slightly longer than the fourth, club slightly longer than the 

 rcmainder; there are near the eye on the upper surface several 

 Short setae which sometimes extend in acurved line across the 

 head elong the clypeal suture, and there are also a frew scattered 

 setae on the disk ot the clypeus. Prothorax froni above about 

 twice as wide as long; sides very slightly convergent from base to 

 apex, and rather evenly and distinctly arcuate; apex about two- 

 thirds as long as the base, transversely and strongly emarginate, 

 angles acute; base broadly arcuate, feobly sinuate at each side of 

 the middle, angles slightly obtuse and rather strongly rounded; 

 disk glabrous, moderately convex, finely and rather feebly punctatc; 

 punctures distant by from two to three tinies their own widths; 

 lateral niargins very narrowly reflcxed and having a row of 

 a few long erect setae. Scutellum very flat, niuch longer 

 than wide, sparsely punctate. Elytra across the humeri slightly 

 wider than the pronotum; sides parallel and nearly straight; together 

 very abruptly and obtusley roundet behind; disk two-thirds longer 

 than wide and three times as long as the pronotum, convex, glabrous; 

 longitudinal costae fine, not punctate, rather feeblc, intervals narro- 

 wer, feebly impressed, finely and irregularly punctate; epipleurae 

 having a row of rather closely placed erect sotae. linder surface 

 opaque, finely and feebly punctate, noarly glabrous except on the 

 coxae and laste ventral segment whore there is a rather long fine 

 and somewhat conspicuous pubescens. Legs slender, long slender 

 posterior tibial spurs but slightly unequal in length; posterior tarsi

This species can be distinguished from sericea by its sraaller 

 size, rnuch paler color, and very large prominent eyes, and also by 

 the shape of the posterior tarsal claw which in slightly shorter, 

 more robust, and with the apical portion finer and prolonged further 

 beyond the inner in sericea. The surface when viewed perpen- 

 dicularly is not iridescent, but a slight amount may be observed 

 when it is viewed very obliquely. The large eyes referred to above 

 is apparently not a sexual character, as the sexes may be very 

 readily separated by the longer or shorter autennal club, and thare 

 is then seen to be no very marked difference in the size of the eye. 

 It may prove a constant character for grouping apart some of the
