Cornops nov. gen. (y.6pvo<p?) 



Allied to the preceding. Head shorter than the pronotum, the 

 vertex nearly flat, the tubercle scarcely descending, triangular, longi- 

 tudinally sulcate, bluntly angulated in front; front rather oblique, 

 perfectly straight, with a rather prominent, nearly equal median 

 carina, running down most of the face and shallowly, broadly sulcate ; 

 lateral carinae sharply defined throughout, a little sinuous. Antennae 

 fully half as long again as the head and pronotum together, linear. 

 Pronotum rounded transversely, gently punctulate, with a scarcely 

 perceptible median carina and no lateral carinae, the front margin a 

 little full, the hind border obtusely angulated, lower edge of the lat- 

 eral lobes full on the posterior half. Tegmina very long and slender, 

 equal, rounded at the tip, but very slightly produced. Wings a little 

 shorter than the tegmina, rather slender. Hind femora with a lower 

 apical lobe, as in Euparnops, but not so conspicuous ; upper poste- 

 rior edge of apical half of hind tibiae produced slightly to a laminate 

 edo-e, and ciliate ; lower apical spines of hind tibiae much as in Eu- 

 parnops, but much more pointed, and produced at the tip. Yalves 

 of female abdomen very stoutly, coarsely and profusely denticulate 

 on the outer margin. 



33. Cornops bivittatum nov. sp. 



Luteous; edges of labrum blackish; antennae, excepting at base, 

 fuscous ; a broad straight black band extends from the posterior edge 

 of the eye to the base of the tegmina. The latter fuliginous, the anal 

 area yellowish, the middle of the costal edge blackish, and all the 

 cross veins of the outer half of the central field black. Wings hyaline, 

 with black veins and cross veins, faintly fuliginous on the outer half, 

 deepening toward the margin, and blackish along the costal edge; 

 the vein marking the anterior fold of the wing and the immediately 

 adjacent parts are luteous. Tip of hind femora, base and tip of hind
