32 DESCRIPTION OP INSECTS 



tarsi only is dilated, and it is granulated beneath as in c(«nm, 

 and of course does not, strictly speaking, belong to this 

 genus. The Baltimnriensis, carbonarius, agricolus, caeniis, 

 and riisticus have also granulations or rather close set hairs 

 on the dilated tarsi of the male. On account of this distinc- 

 tive character, I should have referred them all to that divi- 

 sion of Feronia in which M. Latreille places Epomis, &jc., 

 did not that author expressly state that insects of that divi- 

 sion ought to have the two anterior tarsi only of the male 

 dilated. 



12. H. *rusticus deep black-brown; base of the antennse, 

 mouth beneath and palpi, and posterior thoracic angles 

 reddish-brown ; glabrous beneath. 



Length from two-fifths to half an inch. 



Carahus rusticus. Melsh. Catal. 



Jintennm brown, two basal joints reddish -brown; labiuiu 

 black ; maxillce ^nA palpi reddish-brown. 



Thorax glabrous, a dorsal impressed line, and two abbre- 

 viated ones at base ; margin not depressed, but continuing 

 the general curve to the edge ; hind angles obsoletely 

 reddish-brown. 



Elytra, striae im punctured ; second, fourth, and sixth inter- 

 stitial lines punctured near the tip, marginal one with 

 ocellate punctures not interrupted in the middle. 



Pectus and postpectus not hairy. 



Var. a. Elytra reddish-brown. 



Very similar to H. carbonarbis and equally common ; but 

 is readily distinguishable by tlie colour of the thoracic 

 angles, naked breast, punctures of the interstitial lines, ^c. 



13. H. *carhonarius black; palpi and base of the antennsp 

 piceous ; sternum and postpectus somewhat liairy.
