cation of the tricolor, yet occasional examples do unquestionably 

 appear at first sight to be so far intermediate that I cannot feel 

 absolutely certain that such may not be the case ; and though its 

 reduced elytra might seem perhaps to place it in somewhat the same 

 relation as the true melanocephala to that species, yet it could not 

 possibly be confounded with the latter. Thus, it is narrower, as 

 well as more closely and finely punctured, than the melanocephala ; 

 its elytra and antennae are even shorter still ; its eyes are a little 

 smaller ; and its head is of the same colour as the prothorax (and 

 almost the same as that of the elytra) namely, rufo- testaceous.

This remarkable Lithocharis, which occurs also in Mediterranean 

 latitudes, is tolerably common around Funchal in Madeira proper 

 where it is found amongst garden-refuse, in cultivated spots. But 

 in the Canaries it has been met with hitherto very sparingly, the 

 only examples which I have seen having been taken by Mr. Gray in 

 Palma and by Dr. Crotch in Teneriffe.

 Habitat Canarienses (Can., Ten.), nidos Myrmicarum parce colens. 



A somewhat thick and compact Canarian Sunius which I have 

 taken hitherto only at rather low and intermediate altitudes in Grand 

 Canary and Teneriffe, where it occurs sparingly within the nests of 

 a species of Myrmica. At the Agua Mansa, in the latter of these 

 islands, I once met with it in comparative abundance beneath 

 stones, in company with the ants.
