APPENDIX. 



Obs. Species H.piniperdce affinis,sed major, crassior, in elytris 

 semper (interdum in toto corpore) plus minus ferruginous, elytris 

 grossius transversim rugosis, antennis omnino pallidis, capitulo 

 longiore acutiore, tibiis sensim latioribus extus magis spinulosis, 

 tarsis sublongioribus. 



Found sparingly, at rather low elevations, in Madeira proper, 

 principally, I believe, if not entirely, under the bark of pine-trees. 

 I have not, myself, ever met with it ; but it has been taken, in the 

 vicinity of Funchal, by Mr. Leacock and the late Mr. Bewicke. 



In the ' Ins. Mad.,' as well as in my Madeiran Catalogue, I referred 

 this Hylurgus to the common European H. piniperda ; but I had 

 not compared the species very rigidly, and there can be no doubt 

 that it is in reality quite distinct from that insect. It differs from 

 the piniperda in being on the average a little larger and thicker, 

 and in its elytra (which are more coarsely rugulose) being always, 

 and often indeed its entire body, more or less ferruginous. Its 

 antennae are totally pale, with their club somewhat longer and more 

 acute; its tibiae are rather broader and more spinulose; and its 

 feet are a trifle longer.

Habitat in Gomera et Hierro, a DD. Crotch intra caules Euphorbi- 

 arum copiose repertus. 



I have thought it desirable to give a fresh diagnosis of this Acalles, 

 compiled from additional material obtained by the Messrs. Crotch in 

 Gomera and Hierro, that I may be the better able to indicate in 

 what particulars the following (closely allied) species differs from it.
