344 CANAEIAN COLEOPTERA. 



their humeral callus a good deal developed, and with their interstices 

 rather coarsely transversely-substrigulose and studded with remote, 

 shallow punctures — which are tolerably large towards either side, 

 but smaller and less impressed towards the suture. 



The few specimens which I have treated, in my diagnosis, as a 

 " var. jS " of the present species, and which I hardly imagine can be 

 truly distinct, are a little larger and less shining than the ordinary 

 type, ^vith their prothorax more closely sculptured, with their elytral 

 interstices more even (caused partially by the few scattered punctures 

 being smaller), and with their entire surface even balder still, — the 

 minute hairs with which the species is sparingly beset being so di- 

 minutive as to be scarcely traceable even beneath the microscope. One 

 of them was taken by Dr. Crotch on the subsylvan mountains above 

 Ycod el Alto ; and the remainder by myself at the Agua Garcia.

The only two examples of this Laparocerus which I have yet seen 

 were captured by myself in Teneriffe, on the damp laurel- clad moun- 

 tains above Taganana, during May of 1859. The species may easily 

 be known by its rather narrow and deeply channeled rostrum, by its 

 somewhat small and coarsely punctured prothorax, by its surface 

 being more or less sparingly tessellated with metallic scales, and by 

 the immense punctures of its elytral interstices. It is the last of these 

 characters, in conjunction with its somewhat narrower rostrum and 

 its totalh/ unkeeled and rather less basally-margined prothorax, which 

 appears to distinguish it prlncipalhj from the L, squamosus.
