In the females the front moderately convex, and the 

 whole surface densely punctured, the punctures bee o- 

 ming finer towards centre. The whole front covered 

 with short, erect, fine hairs, slightly inclining and 

 becoming denser towards centre. Pronotum a little broader 

 than long, slightly narrowed towards anterior margin, compared with 

 the elytra rather shining, densely punctured and covered rather sparsely 

 with scales, and furnished with obscure elevated, but not 

 glabrous median line. Elytra somewhat narrower at base 

 than at apex; their striae with deep punctures, each with a row of ex- 

 ceedingly fine, sparse and inconspicuous hairs. Elytral interspaces with 

 coarse rugosities, each interspace covered with 2 — 3 irre- 

 gular rov/s of scales, unigenous in both sexes. On the 

 declivity: interspace 1st elevated, interspace 2nd slightly depressed 

 and narrowed, interspace 3rd elevated, widened and joined to inter-

The galleries resemble those of Carphoborus minimus Fabr., 

 but the egg-tunnels broader and larval mines deeper engraved in wood 

 than those of the Carphoborus minimus. 



I name this species in the honour of three generations of the 

 Russian foresters' family Teplouchov, well known explorers of the 

 Perm district.
