The narrow outline, coarsely alutaceous surface and basally- 

 constricted abdomen of this very d'lstmct Homalota, in conjunction 

 with its depressed forehead, subquadrate prothorax and abbrevi- 

 ated antennae (the first joint of which is greatly enlarged, and the 

 apical one short), will, apart from its numerous other peculiarities, 

 at once characterise it. It appears to be exclusively attached to the 

 damp, putrid stems of the rotten Euphorbias ; and 1 have hitherto 

 only observed it in those of the E. canariensis — under which cir- 

 cumstances I took it abundantly in Gomera, during February, 

 1858, on a hill-top to the north of San Sebastian; and in Fe- 

 bruary of the following year, in similar positions, on the mountains 

 above Santa Cruz of Teneriffe.

Habitat in ins. Gomera, in truncis Euph. canariensis putridis 

 una cum H. canariensi a meipso reperta. 



Readily known from the //. canariensis by its broader outline, 

 convexer head and more transverse prothorax (which is rounded 

 posteriorly, instead of having the angles well defined), as also by 

 its concolorous and sublinear abdomen, and its somewhat brighter 

 and less alutaceous surface. Is eyes, also, are less prominent, 

 and its antennae longer, — their basal joint, moreover, being less 

 inflated, and their apical one not so short. It is far more nearly 

 allied, however, to the H. cacti, from which it simply differs in its 

 wider and more posteriorly-rounded prothorax and rather longer 

 antennae ; whilst from the H. coriaria it may be known by the 

 much paler hue of its somewhat more ample elytra, by the punc- 

 tuation of its head being slightly less dense, by its pubescence 

 being considerably coarser, and by its limbs being altogether
