(J. Eyes extremely large, almost contiguous (narrowly 

 separated iu ? ) ; autennaj moderately elongate, a little longer 

 than in ? , distinctly thickened outwards, joints 7-10 

 gradually decreasing in length, 11 concave within, curved, 

 nearly as long as I) and 10 united ; anterior tarsal joints 1-3 

 with a hiat'kcomb along their inner edge. Genital armature 

 ( Fl. XII. tig. 37) : lateral lobes sinuous within and curved 

 inward at the ti[), as seen from above; median lobe almost

This is a form of the variable /. dimelana, Walk_ ( = car- 

 doni, Bourg.), with the head wholly testaceous, a /\-shaped 

 black mark between the eyes excepted, the antennai shorter 

 and not so slender, and the terminal dorsal segment of the 

 abdomen entire. The median lobe is very similar in the 

 two insects.

cJ . Elongate, narrow, feebly shining, finely pubescent, 

 and sparsely Jiigro-sctose ; testaceous, the head (the labrum

 duced anteriorly, the labrum transverse, trapezoidal, excavate ; 

 eyes very large, ahnost contiguous ; antennse long, slender, 

 filiform, j(»ints 3-10 sube(iual in length, 11 concave, a little 

 longer than 10. I'rothorax longer than broad, scarcely 

 wilier than the head, strongly sinuate at the sides posteriorly, 

 rngnlosely punctate. Elytra long, snbparallel, densely, 

 rugnlosely punctate, without seriately-arranged granules on 

 the disc. Anterior tarsal joints 1-3 with a narrow black
