wide as the clypeus. Pronotum short, nearly four times wider than 

 long, posterior margin nearly straight, slightly medially emarginated 

 laterally, broadly rounding below and behind the eyes, touching the 

 genae, posterior two-thirds finely transversely striated, anterior margin 

 finely granulated. Scutellum very small, tumid, triangular. Elytra 

 coriaceous, coarsely shagreened, nearly square, convex, the costal mar- 

 gin extending down and around the pleura, anterior margin entirely 

 concealed by the pronotum, venation obscure, apparently consisting of 

 about eight nearly parallel slightly oblique nervures, the outer one 

 forked beyond the middle, a broad space between it and the thickened 

 costal margin, the third nervure from the inner margin just attaining 

 the inner posterior angle and probably representing the claval sut- 

 ure. Abdomen broad, convex in both diameters, and in the female 

 rapidly narrowing posteriorly to the narrow pygofers, which are 

 roundingly emarginate above to receive the exserted attenuate ovi- 

 positor. 



Color: Vertex with variable markings of light-yellow and black; 

 usually the following light markings may be made out : A narrow 

 arcuated transverse line marking the boundary of the vertex and front, 

 a median longitudinal line, a line on the posterior margin of vertex 

 and bordering the eyes behind, an irregular line running forward from 

 the posterior margin just inside the eye and a small spot in the mid- 

 dle of the disc on either side. Face light above with several concen- 

 tric dark arcs, which deepen and coalesce below, forming a dark band 

 which includes the antennal pits, below this a broad transverse light 

 band including the apex of front and the superior half of the clypeus, 

 and extending around on the genge under the eye to join the band on 

 the pronotum, the apex of clypeus, a small spot in each basal angle, 

 the facial sutures and the lower margin of the genae dark. Pronotum 

 with the anterior third irregularly black, the remainder consists of a 

 transverse light band which runs down on the lateral margin to con- 

 nect with the light band on the face. Elytra, with the nervures and 

 numerous irregular ramose lines connecting them, light, the interspaces 

 dark with finely maculate effect. Abdomen finely maculate, darker 

 than elytra, below dark fuscous to black, ovipositor and spines on 

 tibiae reddish. 



Genitalia: V, ultimate ventral segment twice longer than pen- 

 ultimate, posterior angles rounding, posterior margin nearly straight, 

 sometimes medially elevated, pygofers long, wedge-shaped, much ex- 

 ceeded by the narrowly comj^ressed oviduct, which is over half the
