THE FLEAS OF NORTH AMERICA 115 



C. Fox (1926) misidentified this flea and described it under the name 

 of AnomiopsyJIus calif 'or mens Baker. In 1929, after Jordan had 

 pointed out that it was really a new species, C. Fox proposed for it the 

 new name faUicalifomicus. 



AXOMIOPSYLLUS MONTANUS Collins 



Anomiopsyllus montanus Collins, 1936, Ent. News 47: 129, figs. 1 and 2. 



Type host. — Bubo xirginianm occidentalis Stone (Montana horned 

 owl). 



Type locality. — Canyon Creek, west of Hamilton, Mont. 



Range. — Known only from Montana. 



The original description of montanus is accompanied by two draw- 

 ings, one of a part of the male terminalia and the other a part of the 

 female terminalia. The type host of this species is probably not a true 

 host. True hosts are probably rodents. 



This species was based upon material misidentified as Anomiopsyllus 

 nudatus (Baker) by Dunn and Parker ( ffi, p. 277 If) in 1923. 



Anomiopsyllus nudatus (Baker) 



Typhlopsylla nudata Baker, 1898, N. Y. Ent. Soc. Jour. 6: 56. 

 Anomiopsyllus californicus Baker, 1904, Invertebrata Pacifica 1: 39. 



Type host. — Neotoma albigula (Hart) (wood rat). 



Type locality. — Tucson, Ariz. 



Range. — Western part of the United States. 



The original description of this species was based on two females. 

 Collins (6, p. 129), in 1936, published a drawing of sternal plate VII 

 of the abdomen of the female. Dunn and Parker (12, p. 2774) , in 1923, 

 misidentified as Anomiopsyllus nudatus material which was later de- 

 scribed as representing a new species (A. montanus Collins) by Collins 

 (6, p. 129), in l$m. 



The Subfamily CHIMAEROPSYLLINAE, new subfamily 



Head divided into 2 parts by the presence of a well developed fronto-epicranial 

 groove or suture ; postantennal region of head dorsally incrassate. Eyes present, 

 pigmented. Front considerably reduced, anterodorsal ; gena extending dorsally 

 to level of upper margin of eye. Labial palpus short, not reaching apex of 

 coxa I. Pronotal comb present. Mesepisternum separated from mesepimeron 

 by an internal, vertical ridge. Hind coxa with a row of spinelets on inner 

 surface. Abdomen without apical spines. 



Contains a single African genus, Chimaeropsylla Rothschild. 



The genus for which this subfamily Chimaeropsyllinae is pro- 

 posed was described by Rothschild (&£, p. 269) in 1911, being based 

 on a single species. He pointed out certain peculiarities of the mouth 

 parts stating: 



* * * The mandibles as well as the labrum are very broad, particularly the 

 former, and closely resemble those of Spilopsyllus cuniculi. Dale (187S), and the 

 Sarcopsyllidae. This peculiar parallelism also obtains in the labial palpi, which 

 show a reduction similar to that which occurs in the fleas mentioned, being but 

 feebly chitinized and consisting of only three distinct segments. 



Rothschild further states that the single included species probably 

 fixes itself to the host by means of the enlarged labrum and mandibles. 

 Chimaeropsylla is restricted entirely to Africa.
