 Sternopsylla texana Jordan and Rothschild, 1921, Ectoparasites 1: 158. 



Type host. — Tadarida mexicana (Sauss.) (bat). 



Type locality. — Pecos, Tex. 



Range. — Southern Texas and ( ? ) northern Mexico. 



For a discussion of the taxonomy of this species read the discussion 

 following the formal description of Stemopsylla. This species was 

 redescribed and figured by I. Fox (25. pp. 108, 191) in 1940. 



The Genus Eptescopsylla I. Fox 



(Fig. 11, A) 



Eptescopsylla I. Fox, 1940, Fleas of Eastern United States, p. 107. Monotypic. 

 Type, Nycteridopsylla chapini Jordan. 



Head without dorsal incrassations. Frontal tubercle absent. Ventral flaps 

 long, slender, nearly straight, tapering to the acuminate apex, with posterior 

 flap much longer than anterior. Genal process rounded posteriorly. Eye ves- 

 tiges large. Ocular bristle absent. Maxilla acuminate. Pronotum with a true 

 comb. Metanotum and anterior abdominal tergal plates each armed with 2 or 3 

 dorsal teeth on a side. Abdominal tergal plate VII with a false comb. Ante- 

 pygidial bristles absent. Fifth tarsal segment of each leg with 5 pairs of plantar 

 bristles, of which the first pair is ventral, the other 4 lateral. 



This genus may be separated from Nycteridopsylla Oudemans, to 

 which if is allied, by the absence of combs on the anterior abdominal 

 tergal plates I to III. The genus Nycteridopsylla does not occur in 

 North America. Eptescopsylla is represented by two species. 



Although the generic host name upon which the name Eptescop- 

 sylla was based has the letter i in it, this letter was omitted in the for- 

 mation of the latter for the sake of euphony. 



Eptescopsylla chapini (Jordan) 



(Fig. 11, A) 



Nycteridopsylla chapini Jordan, 1929, Novitates Zool. 35:39. pi. 2, figs. 30, 31. 

 Eptescopsylla chapini I. Fox, 1940, Fleas of Eastern United States, p. 107, pi. 30. 



Type host. — Eptesicus fuscus (Beauv.) (big brown bat). 



Type locality. — Glen Echo, Md. 



Range. — Probably eastern part of the United States. 



Sexual dimorphism is shown in the chaetotaxy of the head, the 

 female being armed with heavily pigmented, spinelike bristles near 

 the antennal groove, while such bristles are absent in the male. 



Eptescopsylla vancouverensis (Wagner) 



Nycteridopsylla vancouverensis Wagner, 1936, Ztschr. f. Parasitenk. 8' 658 

 figs. 7-8. 



Type host— Las? onycteris noctivagans (LeC.) (silver-haired bat). 

 Type locality. — Vancouver, British Columbia. 

 Range. — Known only from British Columbia. 



In the description of his species, Wagner states that Eptescopsylla 

 vancouverensis is distinguished from E. chapini by the possession of
