thorace ad latera leviter rotimdato, angulis anticis valde rotundatis 

 obtusis, posticis vix productis ; elytris singulis stria suturali pro-

Habitat in pinetis Teneriffse, sub foliis aridis dejectis a DD. Crotch 

 lectus. 



Obs. 0. veloci Europa30 affinis, sed vix ejus varietas geogra- 

 phica ; diifert corpore minore angustiore, capite nitidiore plus 

 minus nigro (rarius concolori), et prothoracis angulis anticis magis 

 rotundatis obtusis, posticis minus evideiiter productis. C. putrido 

 discedit praBcipue eorpore subangustiore ac magis opaco, capite 

 nigrescentiore, prothorace minus convexo necnon ad latera minus 

 rotundato, elytris nullo modo substriatis, antennis gracilioribus. 



Captured by the Messrs. Crotch, rather abundantly, at a high 

 elevation, in Teneriffe, by sifting dead leaves in the Pinal near 

 Ycod el Alto. Possibly, therefore, it may be peculiar to the pine- 

 regions of that and the neighbouring islands. It is very closely 

 allied to the European (and Madeiran) C. v elox ; but it is smaller, 

 narrower, and more regularly elliptic (or less obovate) ; its head is 

 slightly shining, and more or less black (being only concolorous 

 when the insect is immature) ; and its prothorax has the anterior 

 angles more obtuse, or rounded- off, and the posterior ones less evi- 

 dently produced. 



From the C. putridus the pinicola differs principally in its slightly 

 narrower outline and more opake surface, in its darker head, in its 

 prothorax being less convex and less rounded at the sides, in its 

 elytra being quite free from the obsolete stria3 which are distinctly 

 traceable in that species, and in its antennae being slenderer and less 

 clavate. In all probability too its habits are not the same, the single 

 example yet detected of the C. putridus having been found beneath 

 the moist decaying bark of an old laurel in Palma.
