\'ol. XXviii] ENTOMOLOGICAL NEWS 155 



Size small (for the genus); form moderately compressed; surface 

 smooth, of tegmina shining, very closely, finely and deeply cribroso- 

 punctulate. 



Head with the interocular space slightly less than the greatest width 

 of the eye; fastigium acute, depressed, sulcate, the apex well separated 

 from the fastigium of the face; paired ocelli large; fastigium of the 

 face distinctly acuminate; face considerably bullate, moderately com- 

 pressed ; eyes ovate in basal outline, compressed, distinctly directed 

 cephalad; antennae surpassing the apices of the tegmina. 



Pronotum with the greatest caudal width of the disk contained one 

 and one-third times in the greatest length of the disk, the same mod- 

 erately narrowing cephalad ; cephalic margin of the disk very shal- 

 lowly and broadly obtuse-angulate emarginate, caudal margin of the 

 disk very broadly arcuate, faintly flattened mesad ; lateral margins of 

 the disk rather broadly rounding into the lateral lobes : lateral lobes 

 of the pronotum with the greatest depth slightly more than the great- 

 est length ; cephalic margin of the lobes moderately arcuato-sinuate 

 caudad of the eyes; caudal margin regularly and considerably arcuate, 

 the humeral sinus deep, rounded acutc-angulate; ventral margin of 

 the lobes with the cephalic section oblique truncate; ventro-cephalic 

 angle rounded obtuse-angulate, ventro-caudal angle indistinguishable 

 in the regular curve of the caudal section of the ventral and the 

 caudal margins. 



Tegmina surpassing the apices of the caudal femora by considerably 

 more than the length of the pronotal disk; greatest width of the teg- 

 men contained about two and two-thirds times in the greatest length 

 of the same; form of the tegmina elongate elliptical, slightly pro- 

 longed proximad, the distal half more regular in form : costal margin 

 briefly oblique sinuato-truncate proximad, thence rounding into the 

 arcuato-truncate costal margin proper, which regularly rounds distad 

 to the broadly rounded apex; sutural margin (aside from stridulating 

 field) moderately arcuate: marginal field broad, narrowing distad, the 

 greatest proximal width but little less than half the greatest width of 

 the tegmen ; mediastine vein weak, bifurcate; discoidal vein in general 

 straight, with regular oblique rami diverging toward the costal mar- 

 gin; median vein with the ram.us diverging briefly proximad of the 

 middle, this bifurcate mesad ; ulnar vein at the closest point separated 

 from the humeral trunk by one-half the distance separating it from 

 the sutural margin at the point of their greatest remoteness; cross- 

 veins of the discoidal field regular (see figure) : stridulating field rela- 

 tively short and very broad, the free margin produced into a rectangu- 

 late process at the apex of the stridulating vein; distad of this the 

 margin is sinuato-emarginate ; stridulating vein straight, quite thick, 

 sulcate; base of ulnar vein very distinctly paucicrenulate, proximad of
