MITES OF FAMILY CHEYLETIDAE — BAKER 295 



tral seta. Tibia I with a short rodlike sensory seta and four strongly 

 lanceolate serrate setae. Length of body 366/u,, including rostrum SOOju, ; 

 width 300/.. 



Male. — As figured and described by Rodendorf , with four pairs of 

 squamiform marginal setae and three pairs of submedian setae on 

 propodosomatic shield; hysterosomal shield with three pairs of mar- 

 ginal and two pairs of submedian setae. 



Type habitat. — Storehouses. 



Type locality. — Ivanovo ; Agriz, Union of Soviet Socialist Eepublics. 



The description of the female was taken from three specimens col- 

 lected in Bonibus nest, Beaver Mountains, Alaska, March 1, 1942, by 

 C. A. Fowler. The peculiar cloudlike setae of the female were ap- 

 parently overlooked in the original description, and only the setal 

 stems were seen and mentioned as being short, asymmetrical.

According to Oudemans' (1906) redescription of this species it is in 

 general like bishoppi, new species, but is diiferentiated in having a 

 simple ventral seta on the genu of palpus, in having smaller shields, 

 in having fewer marginal setae on posterior shield in that the anal 

 squamiform setae are longer than the simple setae, and in having 

 simple ventral setae on the tibia of the third pair of legs. 



Type habitat. — Dust of caves. 



Type locality. — England. 



EUCHEYLETIA BISHOPPI, new species 



Plate 11, Figures 80-82; Plate 12, Figures 83-88 



Female. — Medium-sized mite, small palpi. Palpal femur strongly 

 swollen on outer side and concave on inner side; dorsal palpal setae 

 squamiform serrate ; genual seta on posterior margin of segment ; genu 

 of palpus with ventral lanceolate serrate seta ; palpal claw with 2 long, 

 narrow teeth ; outer comb about as long as claw, with about 15 teeth ; 

 inner comb about one-half as long as outer and with about 24 teeth. 

 Rostrum of medium size, gradually widening posteriorly, with a few 

 longitudinal sculpturings. Peritreme composed of short, fairly strong 

 segments. Propodosomatic shield wider than long, anterior corners 

 rounded ; four pairs of marginal squamiform serrate setae ; seven pairs 

 of cloudlike dorsal submedian setae as figured. No eyes. Hystero- 

 somal shield with five or six pairs of marginal squamiform serrate
