aspect the dorsal line of the head is moderately declivent from the 

 occiput to the inter-antennal protuberance, which broadly rounds 

 over the ventral section of the facial line to the clypeal sulcus; width 

 of inter-antennal protuberance not quite equal to one-half the least 

 width between the eyes : eyes when seen from the dorsum quite promi- 

 nent, full, in basal outline broad ovoid, flattened caudad: palpi 

 slender, elongate; third joint in length subequal to the fifth joint, 

 moderately arcuate; fourth joint about three-fifths of the length of 

 the third joint; fifth joint trumpet-shaped, flaring quite markedly, 

 the distal margin rather strongly oblique truncate: antennae incom- 

 plete, the proximal joint broad, distinctly depressed. Pronotum 

 rather small, sub-selliform, weakly enlarging caudad, the dorsum 

 rather broadly rounding into the lateral lobes ; cephalic margin of the 

 disk sinuato-truncate, caudal margin arcuato-truncate, medio-longi- 

 tudinal sulcus distinctly indicated mesad and very briefly cephalad, 

 transverse impression weakly indicated, bisarcuate: lateral lobes 

 subquadrate in form, the margins straight, the angles well rounded; 

 ventro-caudal section moderately but not strongly in-bent. Tegmina 

 but little broader than the body, in length but faintly surpassing the 

 apex of the abdomen: lateral field broad, subequal; mediastine vein 

 regularly diverging from the humeral vein, the area between with 

 weakly indicated transverse nervures, which divide the area into 

 subquadrate areolets; accessory veins of the lateral field three in 

 number, situated costad of the mediastine vein, one simulating and 

 subparalleling the mediastine vein, the other two (which are costad) 

 short and sinuate: humeral and discoidal veins straight in general, 

 subparallel: dorsal field with the greatest width at five-eighths the 

 length from the base, distal margin of the discoidal field rounded ob- 

 tuse-angulate; stridulating vein bent arcuate; axillary veins two in 

 number (not counting the thickened marginal node); postaxillary 

 veins three in number; ulnar vein moderately sigmoid, more so proxi- 

 mad than distad; speculum oblique subrectangulate, the greatest 

 width of the same (between angles) equal to about three-fourths of 

 the length, proximal angle weakly acute, distal angle rectangulate, 

 costal angle rounded obtuse, sutural angle rather broadly rounded, 

 figure of the speculum complete, unsjanmetrical elongate subellipti- 

 cal. Wings with the caudate portion projecting distad of the teg- 

 mina a distance equal to three-fourths of the length of the tegmina. 

 Subgenital plate short, slightly transverse, scoop-shaped, the lateral 

 margins converging distad, the distal extremity with a relatively 

 deep emargination, which is made weakly bisarcuate by a median
