The species at present known as PentlUa in our lists must be placed 

 in Smilia Weise (Deutsche Ent. Zeit. 1891, p. 285), and while they 

 have no epipleural fossets as required in the Hyperaspites it seems 

 unnatural to remove SmUia from association with Lofi^, Sticholotis 

 and Cryptognatha. In all these genera there are but five ventral 

 segments, whereas in the other Hyperaspites there are at least six. 

 The essential character of Smilia is the presence of an obliquely im- 

 pressed line behind the anterior angles of the thorax. This line is 

 scarcely visible in mixella. 



H^IWjIA. Weise Pentilin X Lee. 



The species are all quite small, the largest being but little longer 

 than one millimetre, the smallest less than one millimetre. 

 The species may be thus separated : 



Impressed line of front angle of thorax very indistinct. 



Thorax smooth ; sutnral stria of elytra indistinct misella. 



Impressed line distinct. 



Elytra uniform in color, piceous or black. 

 Thorax distinctly punctate; elytra brownish, sutnral stria distinct behind 



the middle rinarginata. 



Thorax not evidently punctate, liut finely alutaceous, elytra jiiceous or l)lack, 



sutnral stria not evident • • . -ovalis. 



Each elytron with oval red si)ot, the twi) narrowly separated at sutui-e. 

 Thorax not punctate, sutural stria not distinct COCCidivora.

 labeled "collected on Piims moiiophylla."

CRYPTOGNATHA Muls. 



The species of this genus are known from any others in our fauna 

 by the presternum in front forming a lobe concealing the mouth- 

 parts in repose. The middle and hind legs are received when re-
