male slightly dilated, and covered beneath with a dense brush of

PEDINUS Latr. 



P. SUTURALIS. — Black ; head and thorax minutely punctured ; 

 elytra with punctured striae, and small prostrate hairs. 



Inhabits Missouri. [264] 



Head rounded ; anterior emargination small : labrum trans- 

 verse : thorax, punctures distinct, dense : scutel rather large : 

 elytra, striae impressed, punctured ; interstitial lines with very 

 minute indentations, furnishing small, pale prostrate hairs : wings 

 none : beneath piceous-black : venter slightly granulated, with 

 very short hairs. 



Length half an inch. 



I place this species in the present genus, from the circumstance 

 of its being altogether destitute of wings, although the elytra 

 are not united at the suture.
