base. Tegmina witli the dusky markings not forming definite bands as a 

 rule. 



Vertex between the eyes rather broad, bounded by a sharp wall, with 

 a well detined carina lunning longitudinally through the middle ; frontal 

 costa moderately prominent, contracted a little at its upper end and at the 

 ocellus, widening below ; sulcate throughout, deepest at the ocellus, the 

 bounding walls or carinas sharp, reaching the clypeus. Antennce normal. 

 Pronotum with the anterior lobes a trifle more contracted above than 

 usual, the median carina distinct throughout, considerably elevated on the 

 anterior lobes where the disk is much swelled and tuberculate. Tegmina 

 rather narrow, extending beyond the abdomen one third their length. 

 Posterior femora reaching the tip of the abdomen. 



The general color is a dirty grayish yellow or yellowish brown, pro- 

 fusely flecked with irregular brownish dots. Face and sides of pronotum, 

 with the anterior and middle legs, dirty whitish gray, densely flecked with 

 various shades of brown ; there are a few black dots and dashes along the 

 carinse of the face, pronotum and posterior femora. Antennae annulated 

 with alternate rings of testaceous and obscure brown. Tegmina cinereous 

 brown on the basal two-thirds, transparent on the apical third, flecked 

 with numerous small, quadrate, obscure brown spots, which, in some 

 specimens, are pretty evenly distributed over the wing, while in others 

 they are gathered into three irregular bands, the basal one occupying the 

 basal third, the middle one the centre, and the other the apical third of the 

 wing ; beyond this the priiicipal veins are brown, while there are also a 

 few of the quadrate spots scattered at random. Wings beautiful sky-blue 

 at base, gradually fading toward the middle, where the colored portion 

 terminates. At this point and where the fuliginous band usually occurs, 

 the nerves and nervures are dark, but otherwise there is no indication of a 

 dusky band. Beyond this the wings are perfectly transparent, with nerves 

 and nervures near the apex dusky. The upper portion of the thoracic and 

 basal abdominal segments is tinged with a faint bluish color. Posterior 

 femora with two dusky spots on the upper edge which are continued as 

 black bands on the inner face, where the apex is also black ; posterior 

 tibiae glaucous, with the inner base black, followed below by a rather wide 

 yellowish white annulus, spines black-tipped ; tarsi bright yellowish white. 

 Lower surface dirty whitish.
