384 PROCEEDINGS OF THE ACADEMY OF [Sept., 



slight and rounded; apex slightly recurved dorsad, rovuided obliquely 

 truncate; intercalary vein distinct, about intermediate in position 

 except dorsad where it regularly approaches and joins the median 

 vein. Wings long and narrow, the width being contained twice in 

 the length ; costal margin evenly and verj^ gently arcuate in the distal 

 half; apex very narrowly rounded; axillary field arcuate apically. 

 Caudal femora quite slender, gently tapering, the width contained 

 about three and a half times in the length, pregenicular constriction 

 not great, pagina rather flat, the sculpturing regular and quite distinct ; 

 caudal tibiae with nine spines on the external margins. 



General colors ecru drab overlaid with bistre in the male, the lighter 

 color on the head and pronotum hoary white. Head with the facial 

 and costal carinas maculate with blackish brown, a large maculation 

 beneath the base of each antenna and the ventral section of the eye 

 marked with the same color in the male, the ventro-caudal section 

 of the gense being washed with the same tint and a postocular stripe 

 indicated, while the fastigium is marked with pale cinnamon-rufous 

 and a pair of arcuate diverging bars of the same color are present on 

 occiput as well as a blackish interocular bar on the vertex; antennse 

 rather broadly annulate with the two general colors. Female with 

 the head finely sprinkled with blackish spots with a trace of a light 

 postocular bar. Pronotum of the male with a median bistre area 

 which narrows caudad and the lateral lobes of prozona are strongly 

 washed with bistre, forming a contrast Avith the hoary metazona. Pro- 

 notum of the female marked much as in the male, but the whole darker 

 and without light colors, while the lateral angles of the disk and a 

 distinct oblique bar on the lateral lobes of the prozona are darker than 

 any of the other pronotal markings. Tegmina with two complete trans- 

 verse bars, one median, one at the proximal fourth and an incomplete 

 bar just distad of the median transverse one, which is broader mesad 

 than at the costal and sutural margins, the bar at the basal fourth 

 toward the sutural margin approaching the median bar and also 

 extending proximad in the intercalarj^ region; distal third with small 

 irregular maculations which are chiefly along the veins. Wings with 

 the transverse bar bistre and situated in the middle, ciuite narrow as 

 the width is not quite a third and a little more than a fourth of the 

 width of the wing, caudad the band arches very slightly proximad 

 and only slightly suffuses the caudal margin, the stigma broad and 

 heavy and extending about half way to the base ; distal section hyaline 

 with the longitudinal veins broadly suffused with bistre toward the 

 apex; proximal half primrose yellow. Cephalic and median limbs
