Vol. VI] VAN DUZEE— SPECIES OF ORTHOTYLUS HI 



male. Front moderately convex, polished; clypeus small, but 

 little prominent. Antenn.ne rather short, the basal joint as long- 

 as the head ; second about three and one-half times as long as 

 the first. Pronotum rather long and much narrowed before, 

 its length two-thirds its basal width, the sides distinctly con- 

 cavely arcuated with the anterior angles well rounded; sur- 

 face rather flat, obscurely transversely rugose ; callosities large, 

 oval, moderately prominent, distinctly separated by a depressed 

 area. Basal lobe of the scutellum well exposed. Elytra nearly 

 parallel, the costa feebly arcuated; tip of the abdomen nearly 

 attaining the apex of the cuneus in the male, quite so in the 

 female. 



Male genital hooks black ; the dextral large, slender at base 

 and expanded to an oblique triangular apex which passes the 

 middle of the anal opening; sinistral hook finger-like, consid- 

 erably surpassing the apex of the segment, clothed with minute 

 hairs. 



Color above black ; beneath pale with a blackish vitta along 

 each side, which in the male may be so extended as to cover 

 nearly the entire lower surface. Pronotum pale with two ap- 

 proximate black dorsal vittae which in the male are so extended 

 as to cover nearly or quite the entire surface. Head in the 

 male black, polished, with the occipital margins, antennal sock- 

 ets, lower cheeks and tip of the clypeus pale ; in the female pale 

 with a large brown annulus on the front and sometimes with 

 two small points above it and a large black spot between the 

 antennae covering the disk of the clypeus, apex of the front and 

 inner cheeks. Antennae black in the male, pale and somewhat 

 infuscated in the female. Scutellum black, with a pale median 

 vitta in the female and sometimes in the male. Pale costal bor- 

 der of the elytra encroaching upon the black disk along the 

 claval suture and principal nervure, especially in the female; 

 cuneus pale with the apex a little infuscated at times. Mem- 

 brane infuscated, the nervures pale and with a pale spot at their 

 apex in the female. Legs pale, the weak tibial bristles also pale, 

 the apex of the tarsi black. Upper surface sparsely clothed 

 with minute pale hairs. 



Redescribed from a good series taken at Quinze Lake, 

 P. Q., and about Bufifalo, N. Y. It occurs on willows. I would 

 not be surprised to learn that the females of this species are
