Habitat Canariam Grandem, in arbore quadam fici emortud ad 

 Mogan mense Aprili a.d. 1858 depreliensus. 



The present PJiloeophagus differs from all the other Canarian 

 species hitherto observed in its somewhat smaller size, narrower 

 outline and more piceous hue. In its only slightly-expanded 

 antepenultimate tarsal-joint (which, however, is broader than in 

 that species), as well as in its habits (for it appears to be attached 

 to the fig-trees of comparatively low elevations), it approaches the 

 P. simplicipes ; nevertheless, apart from the characters just alluded 

 to, its less deeply sculptured surface, somewhat more compact 

 funiculus-joints, less obliquely-truncated shoulders and usually 

 imperceptible seutellum, will immediately separate it from that 

 insect. Indeed, out of ten examples from which the above 

 (typical) diagnosis has been compiled, it is only in one of them 

 that I can detect the least trace of a seutellum, even beneath the 

 highest power of the microscope (though a small triangular place 

 for its reception is just visible); whereas in the last species the 

 seutellum is, in all instances, remarkably conspicuous. 



The var. ft (from Lanzarote and Fuerteventura), which may 

 possibly be specifically distinct, is, on the average, a trifle larger 

 than the Grand Canarian type, with its seutellum rather more 

 perceptible, and its prothorax a little less deeply punctured. The 

 ten specimens from Grand Canary were found in the rotten wood 

 of an old fig-tree at Mogan, towards the south-west of the island, 

 on the IGth of April, 1858. Of the var. ft I have hitherto cap- 

 tured only four examples in Lanzarote and one in Fuerteventura; 

 but two more of it were taken in the former island by Mr, Gray. 

 I believe they all occurred in decayed fig-trees. 



Genus Caulotrupis. 

 Woll., Ins. Mad. 308, tab. vi. f. G, 7, 8, 9 (1854). 

 I am far from being convinced that this genus can properly be 

 dissevered from Phlceop/iagiis ; and it was mainly through the 

 species which compose it being somewhat remarkable externally, 

 and appearing to consliturc a small geographical assemblage 

 peculiar to the Madeiras, that I tliought it desirable originally to
