quadrangular^ dilated at the apex, the basal portion longer than the apical, rather closely punctate. 

 Prothorax a little broader than long, somewhat feebly bisinuate at the base, the sides subparallel behind 

 and feebly rounded and subobliquely converging forwards to the shallow subapical constriction; coarsely 

 somewhat closely punctate, except along the smooth median line, which becomes cariniform posteriorly 

 and is limited on each side by a shallow transverse depression. Scutellum small, subquadrate.. Elytra 

 much wider than the prothorax, moderately long, parallel ; closely crenate-striate, the interstices about 

 as wide as the striae, almost flat, minutely uniseriate-punctate. Beneath rather sparsely punctate • 

 ventral segments 1 and 2 excavate down the middle. 

 Length 4^, breadth 1^ millim. ( tf .)

Two males, probably found under bark of deciduous trees, which cease at about an 









elevation of 8000 feet, and are there replaced by pines. This insect has the elytra

Elongate, rather convex, shining, black, the tips of the tarsi ferruginous. Head deeply foveate and transversely 

 grooved between the eyes, the globose basal portion smooth, the eyes depressed ; rostrum curved, stout, 

 abruptly, quadr angularly dilated at the apex, with the narrow basal portion compressed and longer 

 than the apical, shining or opaque, closely, finely punctate, and smoother or obsoletely carinate down the 

 middle. Prothorax a little broader than long, arcuately narrowing anteriorly, feebly constricted in front 

 and deeply bisinuate at the base; the disc with a transverse, subtriangular, very coarsely punctured, 

 depressed space at the base (which sometimes has a short carina behind), preceded by a broad, outwardly- 

 widened, almost smooth or faintly punctate area, the rest of the surface coarsely punctured. Scutellum 

 small. Elytra long, parallel, considerably wider than the prothorax, transversely depressed below the 

 base ; coarsely, subsinuately, seriate-punctate, the punctures becoming much coarser towards the base 

 and fine towards the apex, the interstices smooth, almost flat, sometimes raised anteriorly. Beneath 

 rather closely punctate ; ventral segment 1 unimpressed, and 5 with a deep transverse fovea, in the <$ .
