spinules of peculiar structure. Presternum sparsely 

 punctate, with short erect hairs, propleurge more coarsely 

 punctate. Abdomen sparsely finely punctate, with short 

 erect spinules. Legs roughly punctured with short hairs. 

 Length, .60 inch; 15 mm. 



This species is very peculiar in its form, having nothing 

 in our fauna with which it may be compared. The widely 

 reflexed thoracic margin, the flat and very acutely mar- 

 gined elytra suggest vaguely Embaphion or some species 

 of Akis. 



The spinules of the elvtra and abdomen are of very 

 peculiar construction. When examined under the high- 

 power hand lense they are seen to be really feathers or 

 spines pectinate on two edges, as in the tibial spurs of 

 Prionochaeta and some other genera.

Exactly of the form of parallcla, dull brown opaque, 

 thorax less opaque. Head sparsely punctate, slightl}^ 

 hairy. Thorax about a third wider than long, widest 

 slightly in front of middle, not wider at base than apex, 

 sides arcuate, apex moderately emarginate, base bisinu- 

 ate, disc slightly convex, a finely impressed median line, 

 lateral margin rather widely reflexed as in parallela, sur- 

 face sparsely punctate, each puncture with a short erect 

 hair, the margin with short hairs. Elytra oval, broadest 

 slightly behind the middle, humeri distinct but not prom- 

 inent, marginal ridge extending nearly to apex, disc flat 

 at middle, a sharply elevated costa arising within the 

 humerus extends three -fourths to apex, a short costa 

 branches from the marginal behind the middle and extends 

 parallel with the inner costa, surface sparsely punctate, 

 with short erect hairs. Prothorax beneath sparsely punc- 

 tate. Abdomen finely not closely punctate, with short
