depressed and narrowed, interspace 3rd highly elevated, inflated and 

 joined to the interspaces 1st and 9th. The ridged parts of interspace 

 3rd form a lyre-shaped figure, enclosing a depressed space, reminding 

 one of the depressions observed in the species of the genus Ips. Inter- 

 spaces 1st, 5th, 7th and 9th have on the declivity small, often obscure 

 tubercles. Interspace 3rd armed on the declivity with distinct promi- 

 nent teeth (fig. 1).

The galleries resemble those of Carphoborus minimus Fabr. 

 From a large nuptial-chamber, engraved in the wood, are diverging 

 4 — 5, rarely 6, — also well engraved — egg-tunnels, inclining, even on

a thick trunk, to accept longitudinal direction. The egg-niches lying 

 rather wide apart with interspaces between them very different. Larval 

 mines long, much involved and winding, and not as deeply engraved 

 in ihe wood as the nuptial-chamber and the egg-tunnels. 



I name this species in the honour of my dear master Prof. N. A. 

 Cholodkovsky, teacher of many present entomologists in Russia. 



Carphoborus teplouchovi, sp. n. 

 Length 1,8 — 2,i mm. Cylindrical. Dark brown. Head almost black. 

 The end of femur, the tibia and the elytra brown, the latter with se 

 cond half lighter. Antennae ;and tarsi yellowish-red. Pronotum and 

 elytra covered with yellowish scales. Head, thorax, legs and abdomen 

 with scale-like stout hairs and partly with simple ones. Front densely 

 punctured. In the males the lower part of the front has a grooved de- 

 pression upon which there are two contiguous tubercles, and is covered 

 with stoping, stout hairs, whose ends are turned towards the tubercles.
