with both the humeral and anterior angles rounded, the latter much more so 

 than in either lurida or ornata. Last ventral segment gradually narrowed to 

 the extremity which is sinuated with the angles much rounded. Uncus when 

 viewed in profile short with the lower side much straighter than in lurida; 

 when viewed from behind, shallowly notched. Fore wings with the venation 

 almost entirely straw colored, slightly darkened about the marginal cells; the 

 basal cell is clear. The membranes at the base of both pairs of wings are

orange, but these as well as the venation, lack the bright color of ornata. 

 Head black with the grooves, front and the region of the transverse rugae 

 almost wholly dull orange. There is a broken black band consisting of four 

 spots extending across the front, and the hollows between the transverse 

 ridges are narrowly lined with fuscous. The terminal part of the rostrum 

 is black, the base is pale. Pronotum black centrally, but margined all round 

 except at the anterior angles with dull orange, and the orange of the grooves 

 considerably spread. This leaves only the central part black, with some irreg- 

 ular black marks on the ridges between the grooves, and a submarginal black 

 band along the sides and posterior margin. Mesonotum dull orange with four 

 obconical black marks on the anterior margin, and a central spear-shaped 

 mark extending toward the orange elevated X. There is a black dot each 

 side at* the anterior extremities of the X, also an interrupted black band 

 extending each side from the X to the base of the fore wing. Metanotum 

 edged posteriorly with orange. Tergum shining black, with the segments 

 narrowly edged posteriorly with orange. The uncus is black. Beneath the 

 legs are light colored except at the knees and the fore femora are somewhat 

 blackened on the inner side ; the abdomen is light, except the usual dark spot 

 centrally near the base, and the valve is also light in color.
