dusky dots scattered through the middle area, especially in the basal 

 half of the wing where it narrows. Vertex of the head very narrow 

 between the eyes, scarcely broader than the first joint of the antennae, 

 the foveola rather deeply sulcate, broadening a little below with high 

 but rounded edges; frontal ridge nearly equal throughout, rather shal- 

 lowly sulcate at and below the ocellus. Pronotum scarcely enlarged 

 posteriorly; median carina very slight, equal, cut only by the poste- 

 rior transverse furrow ; lateral carinse obsolescent, posterior lobe of 

 pronotum punctulate. Terminal segment of abdomen of male 

 squarely docked at tip; cerci rather broad at base, tapering on basal 

 half to about half their width, then equal, and slightly incurved, the 

 lower outer angle rounded off and the outer surface slightly ridged. 



Length of body, 21.75 mm.; of antennas, 9.5 mm.; of tegmina 

 18 mm.; of hind femora, 13 mm. 2 d", taken 15 July, at Dallas, 

 Texas, by J. Boll. 



26. Caloptenus deletor. Brownish fuscous, darkest above, 

 Front of head and sides of pronotum dull, livid brown, with an indis- 

 tinct maculate dusky band between the eyes and the hind lobe of the 

 pronotum, sometimes reduced to a mere line below the lateral carinae; 

 antennae pale reddish, infuscated apically. Tegmina as long as the 

 body, brownish fuscous, with a median line of alternate pale and fus- 

 cous spots; fore and middle legs pale dull brownish, the middle femora 

 blackish above, all the tarsi marked with blackish; hind femora with 

 the upper outer half blackish, sometimes broken into very oblique 

 dashes by a median and postbasal yellowish streak; hind tibiae and 

 tarsi red with a narrow black basal annulus, the tarsal joints tipped 

 with blackish fuscous. Head not elevated, well arched; vertex a 

 little broader than the first antennal joint, the foveola shallow with 

 slight but rather sharp lateral edges, greatly expanding anteriorly; 

 frontal ridge broad, expanding a little next the ocellus and a little 

 sulcate in the same part. Pronotum faintly constricted in the middle, 

 the median carina distinct but slight, nearly equal, cut only by the 

 posterior transverse furrow; lateral carina indistinct excepting on 

 the posterior lobe, the latter obscurely punctate. Terminal segment 

 of abdomen in the male broadly rounded at the tip ; cerci long and 

 slender, compressed, a little incurved, broadest at the base, uniformly 

 and very slightly tapering on the basal half, beyond equal, bent a 

 little forward, broadly and roundly docked at tip, and emitting from 

 the posterior angle a slender, compressed, scarcely tapering shoot
