APOGONIA METASTERNALIS. 207 
NOTE XXX. 
A NEW SPECIES OF THE MELOLONTHID GENUS 
APOGONIA 
C. RITSEMA Cz. 
Apogonia metasternalis , n. sp. 
Easily recognizable by the semicircular impression on 
the middle of the metasternura , which impression is more 
distinct in the male than in the female. 
Length 8,5 — 9,5 mm. — Oblougo-ovate , subparallel, 
glabrous, black, the elytra with a green or purple hue, 
the under surface and legs sprinkled with pale coloured 
bristles. 
The face is deeply and closely punctured (the punctures 
larger and somewhat wider apart than those on the pro- 
notum), and separated from the clypeus by a distinct su- 
ture which is preceded by a transverse smooth streak pro- 
vided with some strong punctures; the clypeus itself strongly 
punctured, the punctures large and close together, the 
anterior margin narrowly reflexed, almost regularly rounded, 
very faintly truncate or emarginate in the middle; as the 
eyes lie in a lower level than the face , the inner orbit seems 
to be slightly thickened. 
The punctuation on the pronotum is very even and 
dense ; the anterior angles of the prothorax are acute but 
not prominent, the sides (viewed laterally) are much 
rounded behind the middle , and the posterior angles are 
very obtuse ; the impressions at the basal margin , in front 
of the lateral angles of the scutellum , are very distinct. 
The scutellum is punctured, and has a smooth space at 
the base or a smooth line along the middle.

208 APOGONIA METASTERNALIS. 
The elytra are covered with large aud deep punctures; 
each elytron shows two very distinct narrow costae, the 
third (originating from the outside of the shoulder) being 
less distinct; along the sides are three rows of strong 
punctures, and the narrow space by which they are sepa- 
rated from the third costa bears on the basal half of the 
elytra a single row of similar punctures ; the sutural in- 
terstice shows a regular row of fine but very distinct 
punctures; the costae, however, of which the second is 
triangularly enlarged at the base, are impunctate; the 
punctuation on the shoulders is obsolete. 
The propygidium is very densely and rugosely, the py- 
gidium very coarsely punctured , the latter bears some 
stiff hairs and shows a more or less distinct median keel. 
The punctures on the sides of the prosternum are ra- 
ther wide apart, on the sides of the metasternum they 
are close together, and on the abdomen they are the lar- 
gest and pitlike , especially on the last segment. The ba- 
sal segments of the abdomen are opaque. The anterior 
tibiae have three teeth of which the upper one is obsolete. 
(ƒ. The middle of the metasternum raised, the raised 
portion provided with a semicircular impression the open 
side of which is turned backward; the four basal joints 
of the tarsi thickened , those of the anterior pair broader. 
Q. The middle of the metasternum less raised, the im- 
pression less distinct, the tarsi more slender.
