This species is very closely related to the preceding one, the prin- 

 cipal difference being in the color of the pubescence. CoccineoMrta 

 has the pubescence varying from light yellow to deep red, while 

 clytemnestra has the pubescence almost pure white, and may prove 

 to be only a variety of coccineohirta. 



Group BIOCULATA 



Females having the mandibles acute at the apex and a tooth on 

 the inner margin, thus bidentate; the antennal scrobes usually not 

 carinate above, but the carina more or less present in some species; 

 postero-lateral angles of head not at all tuberculate; thorax long, 

 subrectangular, the scutellar scale present, and a transverse, sinuate 

 carina immediateh' anterior to the scutellar scale; pygidium longi- 

 tudinally rugose; and the carina of the first abdominal sternite pro- 

 duced anteriorly into a prominent tooth. Males having the man- 

 dibles tridentate; antennal scrobes not at all or obscurely carinate 

 above; tegulae glabrous, impunctate for the most part; the last
