dentate, apical portion reddish except the teeth, very finely 
punctate, rounded on outer margin viewed from above, inferior 
tooth basal; cheeks about as broad as eyes, punctures shallow 
and indistinct, densely pubescent on lower angle, thinly so above; 
vertex flat, deeply punctured, the punctures close behind ocelli, 
otherwise well separated; lateral ocelli slightly nearer edge of 
the vertex than to nearest eye ; front below ocelli very densely 
punctured; antennae long, the joints fully twice as long as wide, 
piceous above, red below, apical joint not much modified. 
Thorax very densely and finely punctured above, the punc- 
tures coarser and well separated on pleura below, sparse on the 
sternum, pubescence whitish on the sides, behind and beneath, 
apparently black on mesonotum (specimen rubbed) with large 
anterior patches of dense pale pubescence, and probably mar-

color in fresh specimens; tegulse piceous, very densely and 
finely punctate; wings fuliginous, nervures brownish to testa- 
ceous, second recurrent nervure entering the second submarginal

Legs piceous, all the tarsi ivory color; front coxae with rather

outer face of front tibia piceous and punctate, the posterior 
margin carinate, the other two faces polished and testaceous, the 
anterior one more reddish; anterior tarsi broadly dilated, the 
basal joint only slightly longer than wide, hollowed out anter-
