General color pale cinereo-testaceous sparsely conspersed on the 

 pronotum, the humeral angle of the tegmina, and the hind femora 

 with dark brown or fuscous spots. 



Head a little broader than the anterior margin of the pronotum, 

 gently depressed, the rostrum squarely truncate in front; eyes large 

 and prominent; ocelli very large, almost touching one another. 

 Apical joint of the maxillary palpi broadly funnel-shaped. Pronotum 

 nearly as long as its basal width, the anterior margin shallowly but 

 roundly emarginate, the posterior margin strongly sinuose. Tegmina 

 narrow, extending well beyond the tip of the abdomen, the median 

 vein eight-branched. Wings lengthily caudate. Anterior and middle 

 legs rather robust, the front tibiae somewhat inflated and provided 

 internally with a large oblong foramen. Hind femora graceful. 

 Last ventral segment, or subgenital plate, fully twice as long as broad, 

 longitudinally channeled at middle, the apex deeply and triangularly 

 fissured, the two lobes evenly narrowed and rounded at their apex. 

 Hind tibiae very irregularly spined, not normal in this specimen. 

 Posterior metatarsus externally three-spined, internally one-spined, 

 the apical spines very large and robust. 



Length of body, cf, 21 mm., including elytra, 25 mm., including 

 wings, 30 mm., of tegmina, 21 mm., of pronotum, 3 mm., width 3.75 

 mm., length of hind femora, 13 mm.

 above sea-level by J. Steinbach. Carnegie Accession No. 4546. 



103. Aphonomorphus obliquus sp. nov. 



Related to A. major, but decidedly smaller, and less robust in form. 

 A rufo-testaceous insect, with four prominently oblique rufous bands 

 on the dorsal field of the tegmina. Body hirsute, in part also sericeous. 



Head moderately large, a little wider than the front edge of the 

 pronotum, depressed between the eyes, which are fairly prominent; 

 ocelli large, elliptical, almost touching, and arranged in an arcuate 

 row between the inner angles of the eyes. Pronotum transverse, 

 strongly hirsute, the anterior end widely emarginate in front, behind 

 roundly produced at middle, lateral lobes high, the lower margin 

 rounded. Tegmina of moderate width, reaching beyond the apex of 

 the abdomen and the tips of the hind femora, the veins rather numer-
