352 NOVITATES ZOOLOGICAE XXXVIII. HISH. FLEAS COLLECTED BY DR. MAX BARTEL.S IN JAVA. By dr. KARL JORDAN, F.R.S. (With 7 text-figures.) T^HE collection of fleas sent by Dr. Max Bartels consists of 30 specimens belonging to 10 species, of which no less than 3 are new, one of them repre-senting a new genus allied to Cfenophyllus, which occurs in Eastern Siberia and North America. The collection, moreover, contains a male oi Paraceras javanicus, of which species we had only the female, the single known male being at Washing-ton. The small series of Ceratophylhis calceatus is likewise most welcome, as but 6 specimens of this species are known. The pair of StivaUu-^ Idus.si obtained by Dr. Bartels renders it certain that St. synetus is the female of .S7. Mossi, and the discovery of a Palaeopsylla extends the range of that genus very considerably. The collection, therefore, is of particular interest, and we thank Dr. Max Bartels sincerely for this contribution to oiu-knowledge of the fauna of Java. The specimens were collected at Tijboeni, Bandong. West Java, by Dr. Max Bartels with the exception of No. 1, which he received from Mr. E. Bartels. 1. Ctenocephalides felis felis Bouche 1835. On Paradoxuruji hermaphrodytus javanicus, 30. vi. 1931, 1 5, an accidental occurrence. 2. Ceratophyllus calceatus Roths. U)o.5. On Rail lis bukit lemmincki, 5.x. 1932, 2 cjc? I Callosciurus nigrovitlatus nigrovittalus, 9.x. 1932, 1 q, 1 $ ; Rattus leplnrus Upturns, 12.x. 1932, 1 $. The specimens from the Malay I'eninsula, Sumatra, and Java do not seem to differ. Cratynius gen. nov. $. Near Ctenophylhis Wagner 1927 (in Konowia, vi, p. 108), but differs from all genera more or less nearly related to Ceratophylhis Curtis 1832 in the mesoster-nite being divided into three sclerites instead of two in consec|uence of the strong development of the internal ridge representing the suture between the sternum (St) and episternum (Est) ; cf. text-fig. 72. Frons and occiput with three rows of bristles, the 4 lower bristles of the anterior row of frons spiniform. sharply pointed ; eye small, above it the internal curved genal rod present in all Ceratophyllids in which the upper eye-bristle is placed near the antennal groove. Bristles of antennal segment II short. Pronotal comb with more than 20 spines, which are narrow and longer than the pronotuni. Surface ridges of thoracic and abdominal tergites and legs some-what coar.se, with minute teeth here and there, apical margins of abdominal tergites I to VII minutely denticulate. Basal abdominal sternite with subbasal lateral bristles. Tibiae with 3 long dorsal bristles (subbasal, median, and apical), the other bristles short (text-fig. 73). Tail of spermatheca very long (text-fig. 74) ; duct of spermatheca Ukewise long, the blind duct on the contrary a mere remnant (D,o.). Genotype : sp. nov. here described.
