prominent longitudinal carina; frontal costa prominent between the 

 antenn;i?, greatl}* contracted above, .sulcate throughout except at the 

 narrowest place at upper end, the sides parallel to the transverse facial 

 groove below the ocellus, below this gently and evenly divergent. 

 P'ace viewed in profile gently hollow. Antennae broadly (female) or 

 narrowl}' (male) ensiform, as long as the head and pronotum combined 

 in the male, but considerably shorter in the female. Sides of pronotum 

 nearlv parallel, provided with four or five well-defined longitudinal 

 ridges; lateral carinse prominent as far as the second transverse sulcus 

 where they divide, one part continuing as the carina, while the other 

 forms a supplementary carina near the sides of the disk and to the 

 hind extremity; median carina strong, especiallv on the front lobe, 

 cut about the middle by the last transverse sulcus; front edge straight, 

 hind margin obtusely angulate. Tegmina extending be^'ond the apex 

 of abdomen as well as the tips of hind femora in both sexes, of moder- 

 ate width and bluntl}- acuminate in the female, in the male about as 

 l)road at their widest part as the length of the pronotum. also some- 

 what acuminate at apex. Wings much shorter than the tegmina, the 

 anterior field of the male with a broadly rounded and heavy front bor- 

 der made up of three heav}^ veins separated by two series composed of 

 numerous short transverse parallel veinlets; the speculum moderately 

 broad and occupj^ing about one-fourth of the entire wing, separated 

 into sections by 8 cross-veins. Hind femora somewhat longer (male) 

 or about reaching (female) the tip of the abdomen, their apices on each 

 side above produced into short acute lamellae of about equal length. 

 Hind tibiai provided with about 15 spines in outer row. Subgenital 

 plate of male abdomen acute, straight, about twice as long as its basal 

 width. Valves of ovipositor short and blunt. 



General color dull testaceous, inclining to bi'ownish, the sides of 

 head, back of eyes, and pronotum along lateral carina' to hind margin 

 with a piceous or dark brown band that continues for a short distance 

 on the basal portion of the discal tield of tegmina. The latter also 

 provided with a few small black or dark brown discal spots basally and 

 beyond quite generally and regularly conspersed with brown; at the 

 extreme base on the hind margin with a small triangular red patch. 

 Wings with the anterior field testaceous and fuscous, except the spec- 

 ulum, which is colorless; basal half of radial field vermillion, crossed 

 beyond by a rather broad l)and of claret, the apical portion and a nar- 

 row space adjoining the speculum smok}- hyaline, with dusk}' veins; 

 in the female the greater portion of the wing is vermillion with the 

 principal longitudinal veins and many of the transverse veinlets of the 

 anterior field brown or black, the apical fourth and outer part of what 

 corresponds to the speculum in the male smokj^ hyaline. Face, sides 

 of head, pronotum, pleura, and abdomen sparsely conspersed with 

 black dots.
