XI. NOTES ON SOME INDIAN APHIDES 
By P. VAN DER GooT, Salatiga {Java). 
During the latter half of 1916,1 had the pleasure through the 
courtesy of Mr. F. H. Gravely of receiving from the Indian Museum 
at Calcutta a new lot of Indian Aphides, in all 27 tubes, most of 
them collected in the Himalayas. Amongst them were several 
apparently new species, the descriptions of which are given in the 
following pages, together with a list of the remaining species con- 
tained in the collection. 
Macrosiphum gravelii, sp. nov. 
Apterous viviparous female. 
Measurements. 
Fig. I. — Maci'osiphiim gravelii , sp. nov. 
a. Head of apterous female (dorsal view), x 65. 
b. Hind part of abdomen of apterous female (dorsal view), x 35. 
Colour. — Body light yellow or light brownish. Eyes red. An- 
tennae light yellowish-brown, the last three joints brownish-black. 
Legs yellowish-white, tarsus black. Siphunculi dark brown. Cauda 
light yellow. (Notes from specimen in alcohol). 
Morphological characters. — Body elongate-ovate, slightly 
arched ; the dorsum with transverse rows of very short spiny hairs.

Records of the Indian Museum. 
[Vol. XIII, 
Antennae slightly longer than the body; relative lengths of 
the five last antennal joints about as: 59. 52. 40. 10. 53. The 
third joint bears on its basal fourth some 3-5 circular sensoriae. 
Frontal tubercles well developed, not gibbous or protruding on the 
innerside; frons slightly arched. 
Rostrum reaching to the second pair of coxae. 
Siphunculi very long, thin, cylindrical, but distinctly expand- 
ed towards the base; the apex with a distinct reticulation, the 
remainder very faintly imbricated. Cauda elongate, ensiform, 
about half as long as the cornicles. 
Legs long and thin, with small but strong spiny hairs. (Des- 
cribed from numerous wingless specimens). 
Food-plant unknown. 
Locality. — Soom (DarjiHng district), 4,000 — 5,000 feet, i6-vi- 
1914 {F. H. Gravely). 
Types in the collection of the Indian Museum, Calcutta; 
No. 5597/h- 1. 
Colour. — Head and thorax yellowish-brown ; abdomen dirty 
yellowish. Eyes and antennae black. Legs black, base of femur 
light yellow. Siphunculi dark brown. Cauda light yellowish. 
Pterostigma of forewing and all veins with a brownish tinge. 
(Notes from specimen in alcohol). 
Morphological characters. — Body broadly ovate, nearly naked. 
Antennae a little longer than the body ; relative lengths of 
the five last antennal joints about as : 60. 42. 33. 12. 65. The 
third joint bears on its whole length some 65 small circular sen- 
soriae ; the fourth joint shows from 0-3 sensoriae. Frontal tubercles 
small, slightly protruding on the inner side. 
Rostrum reaching to the second pair of coxae. 
Siphunculi moderately long, thick, only slightly swollen in 
the middle but considerably constricted at the apex, with a dis- 
tinct reticulation at the tip. Cauda club-shaped, about half as long 
as the cornicles. 
Wings with normal venation ; the second fork of media i 
fairly long, Hooking-hairs 4 in number. (Described from 3 partly 
damaged winged females, in separate tubes). 
Food-plant unknown.

I have little hesitation in considering the winged forms des- 
cribed above, apparently caught on the wing, to be identical with 
the wingless specimen I described in an earlier paper on Indian 
Aphides [Rec. Ind. Mus., vol. XII, 1916, pp. i — 5). 
The reticulation of the cornicles is very rare in Rhopalosiphum , 
the only species showing this character being Rh. aconiti, v. d. G.

The species described above shows much resemblance to the 
genus Greenidea, Schout., especially by the broad body and the 
short cornicles. The absence of an acute point to the last abdo- 
minal segment, however, necessitates it being placed in Trichosi- 
phum (Perg.) v. d. G.

Although only a single damaged alate female was available, 
this species is sufficiently distinct from other species of Trichosi- 
phtim {Tr. minutum, v. d. G. and Tr. querci, v. d. G.) in the number 
and distribution of sensoriae on the third antennal joint.

The species described above is distinct from all other species 
of Lachnus known to me by the numerous sensoriae on the third 
antennal joint in the winged female.

four longitudinal rows of dark brown spots. Eyes red. Antennae 
brownish-yellow, the tips of all joints blackish. Legs light yellow- 
ish ; tarsus, tip of tibia and the femur except the base brownish- 
black. Siphunculi black. Cauda darkish. Pterostigma of fore- 
wings dark brown. (Notes from specimen in alcohol).

Morphological characters. — Body robust, head and thorax with 
numerous, fine, very long hairs, the abdomen less hairy. 
Antennae about 1/3 the length of the body, with numerous, 
fine, long hairs; relative lengths of the four last antennal joints 
about as: 35. 17. 19. 17. Sensoriae are present as follows: III 
I — 2. IV I. V i + i. VI I (+4). vSecondary sensoriae circular, 
moderately small, of about the same size as the primary ones. 
Rostrum reaching to the third pair of coxae. 
Siphunculi broadly conical, but little elevated above the level 
of the body. Cauda obsolete. 
Wings with the typical Lachnus-v ervAtion ; media i, however, 
only once forked. 
Legs fairly long, with numerous fine hairs. (Described from 
a single winged female with damaged hind-wings). 
Food-plant unknown.

Type in the collection of the Indian Museum, Calcutta; No. 
3825/H. I. 
Although described from a single specimen only, I feel. little 
hesitation in considering this a distinct species. It shows some 
resemblance to Lachnus pineti, Koch, but is sufficiently different 
in the distribution of the sensoriae on the antennal joints, as well 
as by media i being only once forked.
