A. smaller than the A. Euphorbia, and with the pubescence 

 rather denser, longer, and somewhat darker. Prothorax rather 

 longer in proportion, though less acuminated (or more regularly 

 and obtusely rounded) anteriorly, where, moreover, it is free 

 from the small marginal asperities, or tubercles, which are so 

 evident in that species ; of an altogether darker hue, the extreme 

 apex only being of a more or less lurid yellow ; sculptured much 

 in the same manner as the A. Euphorbia, but with the punc- 

 tures, as well as the under alutaceous surface, somewhat more 

 coarse and dense ; and with the obscure dorsal ridge narrower 

 and less conspicuous. Elytra a trifle more densely and regu- 

 larly sculptured than in that insect ; and with the front fascia 

 usually broader (or more suffused) and less broken, and the 

 hinder one also more suffused and placed nearer to the apex, to 

 which it occasionally altogether extends. Limbs dusky testa- 

 ceous, being usually less obscured than those of the A. Eu- 

 phorbia. 



The present insect was detected by myself and, subsequently, 

 on the same day (the 23rd of December, 1858), by Senhor Moniz 

 in decayed stems of the Euphorbia piscatoria, between Point 

 Oliveira and the Brazen Head, to the east of Funchal. It was 

 through the fact of having previously captured it in Teneriffe, 

 Palma, and Hierro, of the Canarian group, within the rotten 

 branches of the selfsame plant, that I was induced to commence 

 a search amongst the Euphorbias of the lower elevations of 

 Madeira also ; and the result was that the present Aphanarthrum 

 and the following one (both of them being likewise Canarian) 

 were at once added to our list. It seems to be as common 

 throughout the maritime districts of Madeira as the A. Euphor- 

 bia is in the E. mellifera of loftier altitudes ; for it has been 

 taken abundantly by Mr. Bewicke and Senhor Moniz, not only 

 towards Cani^o (where we first observed it), but also at Porto 

 Novo, and in the region beyond the Cabo Gerao, to the west- 

 ward of Funchal.
