Genal comb with 3 spines 9 



8. Genal process visible above uppermost genal spine; abdominal tergal 



plate VII produced into a process between the 2 sets of antepygid- . 



ial bristles Corrodopsylla Wagner. 



Without these characters Doratopsylla Jordan and Rothschild. 



9. None of spines of genal comb overlapping; tip of each palpus usually 



with a terminal hooklike bristle Ctenophthalmus Kolenati. 



Ventral spine of genal comb overlapped by middle spine ; tip of each 

 palpus without terminal hooklike bristle ; bristles on posterior bor-

The Genus Tamiophila Jordan 



(Fig. 10, D) 



Tamiophila Jordan, 1938, Novitates Zool. 41: 124. Type, Typhlopsylla grandis 

 Rothschild (by original designation). 



Frontal tubercle acuminate. Head with a fronto-epicranial groove. Genal 

 comb consisting of 2 spines, of which the first is short and broad and overlaps 

 the more slender and much larger second one. Eyes vestigial. Labial palpus 

 consisting of 6 segments (counting the somewhat shortened basal segment). 

 Pronotum with comb. Antepygidial bristles present, at least in female. Coxa 

 III without a patch of spinelets on inner surface. Fifth tarsal segment of legs 

 I and II with 5 pairs of lateral plantar bristles. Fifth tarsal segment of leg III 

 with 4 pairs of lateral plantar bristles. 



Two species are placed in this genus, one doubtfully so. 

 Tamiophila grandis (Rothschild) 



(Fig. 10, B) 



Typhlopsylla grandis Rothschild, 1902, Ent. Rec. and Jour. Variation 14: 62, 



fig. 3. 

 Neopsylla striata Stewart, 1926, Insecutor Inscitiae Menstruus 14 : 124. 

 Tamiophila grandis Jordan, 193S, Novitates Zool. 41 : 124. 



Type host. — Tamias striatus (L.) (eastern chipmunk). 



Type locality. — Branchtown, Ontario. 



Range. — Eastern part of the United States and Canada. 



This species was first misidentified as PuJex gigas Kirby by Baker 

 (#, p. 163) in 1895, and for many years thereafter that name was 

 applied to it. In 1929, however, Jordan (^1, p. 172) pointed out that 

 Pulex gigas Baker is identical with grandis and that Pulex gigas 

 Kirby is an altogether different flea belonging in the genus Ilys- 

 trichopsylla. 



The original description of grandis was accompanied by an illus- 

 tration of the male genitalia. The female terminalia and the head 

 have been figured by I. Fox (85, p. 179) . 



This species seems to be exceedingly rare and not often encountered 

 in collections. The extensive collections of the United States National 

 Museum include but a single female specimen. 



Tamiophila (?) texana (Stewart), new combination 

 Neopsylla texana Stewart, 1930, Canad. Ent. 62 : 179, pi. 15, fig. 6. 



Type host. — Rattus norvegicus (Erx.) (house rat). 

 Type locality. — Houston, Tex. 

 Range. — Known only from Texas. 



This species is placed in Tamiophila with hesitation because of the 

 chaetotaxy of the fifth tarsal segment of the hind legs. In the orig-
