hairy. The femora with a small tooth. Length, sine 

 rost., .18 inch; 4.5 mm. 



Related to vittatus and with similar vestiture but less 

 dense, the hairs are simple and not tufted. It differs also 

 in the absence of smooth thoracic line and is without erect 

 set£e. 



One specimen. La Paz. 



Otidocephalus sparsus n. sp. 



Form of scrohicollis, piceous black shining, surface 

 clothed with tufted pubescence not closely placed, thorax 

 and elytra with erect white hairs. Rostrum coarsely punc- 

 tate, smooth at middle in front. Thorax slightly oval, 

 equally narrowed at apex and base, one-half longer than 

 wide, sides feebly arcuate, disc convex, very coarsely and 

 deeply, moderately closely punctate, tufted hairs not closely 

 placed, erect hairs directed toward the front. Elytra 

 oblong oval, widest slightly behind the middle, humeri 

 distinct, surface with strise of moderately coarse punc- 

 tures, not deep nor closely placed, intervals flat sparsely 

 punctate. Body beneath sparsely clothed with tufted 

 hairs and erect setae. Legs piceous, tarsi pale. Femora 

 with small tooth. Claws with broad rectangular tooth at 

 base. Length, .18 inch; 45 mm. 



This species does not particularly resemble any in our 

 fauna; it has vestiture similar to Ulkei, but less dense. 



One specimen in my cabinet, probably from the Cape 

 Region. 



Otidocephalus carinicollis, n. sp. 



Form of scrobicollis, piceous black, surface very dark 

 bronze, shining, clothed with grayish pubescence with 

 smooth spaces, the intervals with semi-erect black setse. 

 Rostrum vaguely bisulcate each side. Thorax elongate 

 oval, one-third longer than wide, widest slightly in front
