CRYPTOPHAQIDAE. 13T 



The genera are thus distinguished : — 



Niatli joint of anteniue very little wider than eighth. 



Body above punctured and pubescent ; thorax not impressed. 



Telmatophilus. 

 Ninth joint as wide as the tenth ; surface very leehly 2)ubescenl. 

 Thorax transversely impresstid at base ; elytra punctured in strire. 



Loberus. 

 Thorax not impressed at hase ; <dytra irregularly punctured. 



Tomarus. 



Tribe II.— CRYPTOPHAGIj^I (genuini). 



The anteiiiice arc inserted at the sides of the front, which is 

 sometimes prolonged; the ninth joint of tlie antenna) is scarcely 

 narrower than the tenth. The anterior coxas are decidedly trans- 

 verse. The tarsi are sometimes 5-jointed in both sexes, but 

 usually the hind tarsi of the male are 4-jointed; the joints are 

 not lobed beneath, and the fourth is but little smaller than the 

 third. The anterior tarsi of the males are slightly dilated, and 

 hairy beneath. 



Two grou^js are known by the following cliaracters : — 



Mesosternum deeply emarginate, receiving the pnjsternum. 



ANTHEROPnAGI. 



Mesosternum not emarginate. Ckyptophagi. 



Group I. — Antherophagi. 



The genus Antherophagus alone, represented by species in 

 the Atlantic district, Central region, and Alaska, constitutes this 

 group, which differs from the next not only by the prostcrnum 

 being more prolonged, with the tip received into the deeply 

 emarginate mesosternum, but by the very different form of the 

 body, which is oval, and resembles considerably a Xitidulide of 

 the genus Epura^a. The head is flat, the front not prolonged, 

 and in the male is deeply incised at tip, exposing a meral)ranous 

 triangular epistoma. The antennae of the female are clnblxd, as 

 usual ; those of the male are stout, and scarcely thickened at the 

 end. The mandibles are prominent, and suddenly incurved at 

 the tip. The hind tarsi of the male are 4-jointed. The genus 

 lives on flowers. Our species are finely punctured, and densely 

 clothed with fulvous hair.
