LVII. HALTICA Geoff. 1764. (dr., "leaping.") 



Oblong or oval, medium-sized, blue, green or bronzed, rarely 

 reddish-brown, species, having the head short, usually deeply in- 

 serted; antennae half as long as body, joints 2, 3 and 4 gradually 

 longer except in rufa; thorax usually one-half wider than long, 

 broadest at base, which is curved and with a more or less distinct 

 transverse line just in front; side margins slightly thickened near 

 front angles ; elytra! punctures confused ; front coxal cavities open 

 behind, the prosternum rather narrow between the coxa 1 ; hind 

 tibiae not or feebly sulcate, terminated by a short spur ; tarsal claws 

 broadly dilated at base. 



The genus is a difficult one, and the species can never be deter- 

 mined with any degree of certainty without a fair number of speci- 

 mens, some of which must be males. Unfortunately, this sex is 

 much less abundant than the females. The following species have~ 

 been found or probably occur in the State :
