628 ON NEW SPECIES OF FLEAS. [May 26, 



3. Ceratophyllus indages, sp. n. (PI. XXXI. fig. 17.) 



We know only the $ . The clifi"erences from the 5 of the 

 preceding species are apparently constant, though slight. This 

 ilea is deeper brown than the preceding one. The seventh abdo- 

 minal sternite is longer, its upper margin being even more 

 ■emarginate distally, while the apical margin is not sinuate at all 

 (PI. XXXI. fig. 17). 



Length : $ 3'1 mm. 



We have six 5 , taken ofi" Sciurus vulgaris orientis, at ISToboii- 

 betsu, near Moruran, Hokkaido, Japan. 



As the diiferences between the females of closely allied species 

 in this group of Cerat02)hylhts are generally slight (quantitatively), 

 we consider that the above-mentioned characters indicate that 

 this insect is distinct from C. argus. The discovery of the c? 

 will doubtless settle the point. 



4. Ceratophtllus andersoni, sp. n. (Plate XXXI. fig. 19.) 



Thorax. — The meso- and metanotum and the abdominal ter- 

 gites 1-7 bear each 2 rows of bristles, the mesonotum having 

 some additional hairs on the back besides the small hairs situated 

 a,t the anterior edge. The metathoracic epimerum has 5 bristles 

 (1, 3, 1). The long apical bristle of the seventh tergite is as long 

 as the first hind-tarsai segment. 



Legs. — The hind femur bears 2 bristles on the inner surface, 

 one being subbasal, the other placed subventra-lly near the apex. 

 The first mid-tarsal segment is about one-fourth longer than the 

 second (20: 16). The bi"istles situated at the dorsal edge of the 

 hind tibia and at the anterior and posterior edges of the hind 

 tarsus are very deep brown. The first hind-tarsal segment, like 

 the second to fourth segments, bears 2 rows of bristles on the 

 outer surface. 



Modified segments. — $ . The seventh abdominal sternite is 

 quite unlike that sclerite of the allied species, being less broad 

 vertically and much more rounded (PL XXXI. fig. 19). The eighth 

 tergite bears a few more bristles than in the preceding species. 

 The bristles of the tenth sternite are veiy stout. The stylet is 

 four times as long as it is bi-oad at its base. 



Length: 5 3*1 mm. 



We have one $ , taken oj6f Putorius itaisi, at Takamori, 

 Xumamoto Ken, Kiushiu, Japan, on April 6th. 



5. Ch^topsylla globiceps Tasch. (1880). 



Pulex globiceps Taschenberg, Die Flohe, p. 66. n. 6, t. 2. figs. 10 

 10«, 11 (1880) (ofi- Fox and Badger). 



There are five 5 in the collection, which are apparently identical 

 with European specimens. Ta.ken from Meles anakuma, at Jinrio, 

 Tokushima Ken, Shikoku, Japan, on February 1 7th,
