HOKIA Fab. Oliv. 



H. SANGUINIPENNIS. — Body black ; elytra sanguineous) im- 

 maculate. 



Inhabits Pennsylvania. 



Body short, robust, deep black, scabrous, with dense punctures : 

 head lobate at the basal angles, with a slightly elevated, longitu- 

 dinal, glabrous line on the front; antennae inipunetured ; third 

 joint as large or larger than the first; terminal joint [280] 

 acuminated from its middle : mandibles glabrous, and with the 

 palpi impunctured : thorax transverse-quadrate, very obtusely 

 rounded behind : scutel conspicuous, rounded behind, punctures 

 more minute than those of the thorax : elytra very flexible, san- 

 guineous, immaculate : feet punctured ; nails denticulated on the 

 middle, tip and base simple. 



Length more than two-fifths of an inch. 



This species is an interesting addition to the catalogue of 

 North American insects, as it is the only one of its very limited 

 genus, yet found here: It must be rare, only a single specimen 

 having yet occurred. It is very distinct from the three or four 

 species already known. 



MELOE Linn. Latr. 



1. M. ANGUSTicoLLis. — Thorax narrower than the head; 

 elytra and abdomen violaceous. 



Inhabits Pennsylvania. 



Body dark violaceous, punctured : head with profound pun- 

 tures, an impressed, longitudinal, abbreviated, acute, frontal line ; 

 and a transverse, elevated, obtuse one connecting the bases of 

 the antennae : thorax slender, narrower than the head, profoundly 

 punctured, widest rather before the middle, and narrowed at tip 

 and base ; base emarginate, and slightly margined : elytra rugu- 

 lose, dark bluish-violaceous: feet slightly hairy, spines [281] 

 of the tibia, and nails ferruginous : abdomen slightly rugulose, 

 dark greenish, or violaceous : tergum each side black, opaque. 



A rare species, very distinct from the M. americana of Leach, 

 which is not uncommon, and is sometimes gregarious in great 

 numbers ; the thorax of angusticollis is strikingly narrower pro- 

 portionally, as well as the head, than the body ; and the colors of
