THERMONOTUS PASTEUR!. 249 



Thermonotus Pasteuri is extremely close to and shows 

 a striking resemblance with Th. apicalis Rits, , but is easily 

 distinguished from that species by the more robust protho- 

 rax which has the lateral spines much less slender , by the 

 black colour of the abdomen , metasternum and coxae , etc. 



Length 22 — 23 mm., breadth at the shoulders of the elytra 

 8^/2 — 9 mm. — Brick red, the apical half of the mandi- 

 bles, the eyes and antennae, a spot along the middle of 

 the scutellum , the entire legs , the metasternum and the 

 abdomen black, the upper lip and the apical joint of the 

 palpi blackish, the apical third of the elytra dark steel 

 blue. The prothorax and the red portion of the elytra are 

 (in places , as my couple is somewhat rubbed) covered with 

 a very dense , almost crustlike , ochreous pubescence ; a 

 reniform spot of a similar pubescence is present on the 

 head (which inter alia for the rest is almost smooth) be- 

 hind the upper lobes of the eyes ; on the steel blue apical 

 portion of the elytra and on the dark spot of the scutel- 

 lum the pubescence is black; a small spot of a white 

 pubescence is present on the under surface of the base of 

 the 3rd and following antennal joints. The sides of the 

 abdomen, the metasternum and the legs are thinly covered 

 with a delicate greyish pile. 



The head is nearly smooth and impunctate , but provi- 

 ded along the middle with a narrow raised dark line which 

 extends from the anterior margin of the clypeus up to the 

 prothorax; a slight impression is to be seen along the 

 middle of the vertex , and another impression , which is 

 sharply bounded on the inside , is situated between the 

 base of the eyes and mandibles. 



The prothorax is robust and transverse , and measures 

 from point to point of the lateral spines 8^/0 — 9 mm. ; 

 the anterior transverse groove is angularly curved backwards 

 in the middle ; the disk between the lateral spines is raised, 

 has an uneven , coarsely punctured surface , and a mesial 

 smooth streak which is notched at the base opposite the 

 scutellum ; the lateral spines are very broad at their base ,
