 It. Antenna' not pilose; form elongate, slender, cylindrical. 



<-. Body above nearly uniform gray; tarsal claws feebly toothed or 

 cleft. LXIX. MECAS. 



re. Body above never uniform gray, usually bicolored, with small black 

 spots on thorax; tarsal claws broadly toothed. LXX. OBEREA. 

 '>}>. Antenna? thickly pilose with long black hairs; form shorter, elongate-

 Eyes completely divided, the upper and lower portions widely sepa- 

 rated ; thorax dilated or tuberculate on the sides.

 ly toothed. LXXI. TETROPS. 

 (]il. Form robust ; color red with black srx>ts ; tar-

LXIX. MECAS Lee. 1852. 



Our members of this genus are slender, 

 lil ack species, clothed with gray pubescence. 

 They resemble small Saperdas, but have the 

 front short and subeonvex instead of flat and 

 quadrate, and the tarsal claws cleft. Their 

 habits are, moreover, different, as they do not 

 breed in wood, but in the stems of herbs or 

 weeds. One of the five known species has 

 n eeu taken in the State, while two others may
