The Subgenus DACTYLOPSYLLA Jordan 



This subgenus is here diagnosed for the first time. 



With the characters of the genus Dactylopsylla and in addition: In male, 

 sternal plate VIII large, divided posteriorly into a pair of large, flat lobes; 

 sternal plate IX with a pair of large, inner, vertical processes, a conspicuous, 

 anterior, median apophysis, and a pair of large, conspicuous, posterior processes, 

 each being divided into a proximal and a distal lobe by a broad ventral sinus; 

 movable finger of clasper long, slender, hooked backward at apex; penis with 

 dorsal portion of outer sheath modified into a long, downwardly curved, finger- 

 like process. 



Type species. — Same as for the genus Dactylopsylla, Dolichopsylla 

 bluei C. Fox. 



Although at first glance the modified segments of the male in this 

 subgenus appear to be of an entirely different type from those of the 

 other subgenera of Dactylopsylla, yet upon closer study the differences 

 observed are found to be in the shape and size of parts rather than 

 in the general plan of the terminalia or in the relations of the parts 

 to one another. This point is further discussed under the description 

 of the subgenus Foxella Wagner. 



Dactylopsylla (Dactylopsylla) bluei (C. Fox) 



(Fig. 5, A) 



Dolichopsyllus bluei C. Fox, 1909, Ent. News 20 : 195, figs. 1-4. 

 Dactylopsylla bluei Jordan, 1929, Novitates Zool. 35 : 38. 



Type host. — Mustela xanthogenys Gray (weasel). 

 Type locality. — San Francisco, Calif. 

 Range. — Known only from California. 



The original description of this species, which is based on females 

 only,- is accompanied by a drawing of parts. 



Dactylopsylla (Dactylopsylla) comis Jordan 



Dactylopsylla comis Jordan, 1929, Novitates Zool. 35 : 38, pi. 2, fig. 26. 



Type host. — Thomomys fuscvs (Merr.) (pocket gopher). 



Type locality. — Okanagan Landing, British Columbia. 



Range. — Known only from British Columbia. 



The male of comis is unknown. According to the original descrip- 

 tion of the female the apical margin of sternal plate VII is rounded 

 and not produced into an angular lobe as in bluei. 



Dactylopsylla (Dactylopsylla) stimsoni (C. Fox)

Type locality. — Los Angeles, Calif. 



Range. — Known only from California. 



The original description of stimsoni was based on the male sex. 

 It is accompanied by drawings of the head, terminalia, and posterior 

 tarsus.
