The general aspect of this insect is that of some of our brown 

 Ehiters. As will be seen above the sexes are quite different in the 

 form of the antennae ; the male seems rare. 



Occurs in jNIaryland, Pennsylvania and Indiana (Say). 



P. Ullcei n. sp. — Form oblong, parallel, equally obtuse before and behind, 

 dark brown, moderately shining, sparsely clothed with short fulvous pubescence ; 

 antennae shorter than half the body 9 ; head coarsely and densely punctured, 

 front slightly depressed, a feeble impressed vertical line ; thorax one-foui-th 

 wider than long, sides behind straight and parallel, apical third arcuate, hind 

 angles not carinate ; disc convex, a feeble median impressed line, nearly obliter- 

 ated at middle, surface moderately punctured, densely toward the sides and base, 

 more sparsely at middle ; elytra parallel, obtuse at apex, narrowing at apical 

 fourth, distinctly finely striate, the intervals flat, densely punctate, the punctures 

 finer than on the thorax, but not rugose; body beneath densely and rather finely 

 punctate. Length .38 - .40 inch ; 9.5-1(1 mm. 



Male. — Antennse with first joint as long as the next three, second small, partly 

 concealed behind the first, half as long as the third, third equal to the next two, 

 which are equal .sixth, seventh and eighth a little shorter, equal, ninth equal to 

 sixth, seventh and eighth together, tenth shorter than the ninth, the eleventh 

 longer. 



Female. — Third joint of antennse nearly as long as the next two, fourth and 

 fifth equal, sixth, seventh and eighth subequal, longer than wide, each a little 

 shorter than the fifth joint, ninth broader than the eighth and as long as the 

 three preceding, tenth a little shorter, eleventh longer and more slender than the 

 ninth. 



Broader and more obtuse than heterocerus, with finer punctuation 

 and pubescence, and with narrower hind coxal plates. 

 .Occurs in Ohio ; given me by Mr. Ulke. 



CRYPTOSTOMA Latr. 



Form oblong, parallel ; antennse varying in the sexes ; head rather deeply in- 

 sei'ted, eyes transverse ; clypeus narrowed at base, narrower than the distance to 

 the eyes, apical margin broadly arcuate, mandibles presenting a narrow face ex- 

 ternally ; prothorax a little wider than long, lateral margin distinct in its entire 

 length ; scutellum oval ; elytra striate ; prosternal sutures straight, well defined, 

 very slightly divergent, propleural region triangular, the apex truncate, not sul- 

 cate for the antennse ; metasternal episterna moderately wide, parallel, the 

 epimera not visible ; hind coxal plates gradually but widely dilated internally ; 

 legs moderate ; tansi slender, the first joint as long as the next three, the fourth 

 simple, claws simple. 



The only genera in our fauna to which this is allied are Anelastes 

 and Phlegon, from either of which it may be so easily known as not 

 to require special comparison here. 



One species is known to me, and the specimen is a female, and the 

 following description of the antenna) applies to that sex alone :
