THE FLEAS OF NORTH AMERICA 103 



The Genus Actenopsylla Jordan and Rothschild 



Actenopsylla Jordan and Rothschild, 1923. Ectoparasites 1: 309. Monotypic. 

 Type. ActenopsyUa suavis Jordan and Rothschild. 



This genus includes but a single rare species, representatives of 

 which are not available for study, hence the original description by 

 Jordan and Rothschild is here given in full. 



Near SpUopsyUus Baker (1905). Without ctenidia. Mandibles normal, not 

 enlarged. 



Frons strongly rounded, without tubercle or angle, with two long bristles, one 

 in front of the eye. the other near the ventral margin above the maxillary palpus ; 

 internal projection above maxilla small. Occiput with many small bristles 

 above antennal groove. Club of antenna as in SpUopsyUus segmented all round, 

 longer in 5 than in $ , bristles on upperside of segment II. long. Labial palpus 

 with four segments. 



Pro- and mesothoracic tergites and abdominal tergites II. to VII. with one row 

 of bristles. Metepimerum with a bristle above stigma, the distance of the stigma 

 from the upper margin of the epimerum being much greater than in SpilopsyUus. 

 Stigmata III. to IX. of equal size, not so large as in SpUopsyUus, but the diameter 

 of a stigma more than twice the diameter of the groove of a large bristle of the 

 posterior row of the respective segment ; cavity of last stigma very large. 

 Hindcoxa on inner side with a row of (about) six to eight small spines; mid- 

 and hindfemora with a subventral row of bristles on the inside ; segment I. of 

 midtarsus as long as II., Y. of all the tarsi with only 3 pairs of plantar 

 bristles. 



The authors of this genus place it nearest SpilopsyUus Baker. It 

 is also closely related to Parapulex Wagner.

 312. 313. 



Type host. — * s Xest of Ptychoramphus dLeuticus* (Cassin's auklet). 



Type locality. — Coronado Island. Mexico. 



Range. — Known only from Mexico. 



The original description of this species was based on one male and 

 seven females, and is accompanied by a drawing of the genitalia of 

 the male and the tip of the abdomen of the female. 



The Genus Xenopsylla Glinkiewicz 



(Fig. 12, D and G) 



Xenopsylla Glinkiewicz. 1907, Akad. der Wiss. Wien, Math.-Nat. Kl. Sitzber. 116: 

 3S5. Monotypic. Type (Xenopsylla pachyuromydis Glinkiewicz > =X. chcopis 

 (Rothschild). 



Loemopsylla Jordan and Rothschild, 1908, Parasitology 1 : 15. Type. Pulex clieopis 

 Rothschild (by original designation). 



Front short, high, with anterior margin broadly rounded. Frontal tubercle 

 absent. Genal comb absent. Eye large, unreduced, black. Labial palpus 4-seg- 

 mented. both anterior and posterior margins well sclerotized. Antennal club 

 short, not segmented on anterior surface. Episternum III divided into upper 

 and lower parts by a deep suture. Pronotal comb absent : pronotum with a 

 single transverse row of setae. Hind coxa with a row or patch of spinelets 

 on inner surface. Femora almost devoid of lateral setae. Segment V of each 

 tarsus with 4 pairs of lateral plantar bristles. Abdomen with long setae, but 

 without apical spines. Sternal plate VIII of male large, broad/ unmodified. 

 Sternal plate IX of male with an anterior, whiplike apophysis, a pair of poorly 

 sclerotized. inner, vertical processes, and a pair of simple, more or less clavate, 

 posterior processes.
