their extremity. It docs in fact form somewhat of a connecting link between the 

 typical and aberrant Atlantides ; for whilst its excessively pilose elytra, and the 

 slis^htlv incrassated leers and the armed tibia? of its males must needs (as the most 

 important of its characters) retain it amongst the former, yet the posterior tibia? 

 being undilated at their termination wovxld tend to identify it with the latter, did 

 not the singular and very acute Httle spur, with which they are fortified behind 

 then- apex, exist, to represent the inner heel (as it evidently does), which is more 

 or less largely developed, and modified, throiighout the whole of the normal 

 members of the group. The A. lanatus is a rather abundant insect towards the 

 {owQY limits of the wooded districts, — occm*ring occasionally, likewise, beneath 

 stones in more open spots. I have not myself observed it except in the south of 

 the island ; but have taken it conamonly, during the autumnal months, at tlie 

 Curral das Romeiras, above Funchal, — and it was captured by Professor Heer at 

 the Mount Church, and on the Pico da Cruz, dming the -ndnter of 1850-51.

A. elongate-ovate, rufo-piceous, and sparingly variegated with a robust, decumbent, green and golden, 

 or golden-grceu pubescence, — reflecting a metallic splendour. Rostrum and prothorax as in the 

 last species ; the latter being a little more distinctly keeled in the centre, but with the same 

 character of punctuation (namely, large punctures with minute ones between, the former having 

 impressed radiating lines divergent from each of them). Elijtra somewhat parallel towards their 

 base; rather deeply punctate-striated; quite free from additional pile except at the extreme apex, 

 where there are a few, tolerably elongated, erect, and exceedingly soft, or silken hairs ; pinched 

 in on either side about the apex, causing the suture in that region to be prominent and keeled, 

 and that poi-tion of the body consequently to be boat-shaped ; the alternate interstices rather 

 distinctly tessellated with denser patches of the golden-green ])ubesccnce. Antenna somewhat 

 long and slender, rufo-ferruginous ; their scape slender at the base, being rather suddenly 

 thickened towards the apex : the first and second joints of their funiculus of aboftt equal length. 

 Legs more or less rufo-fenuginous, exceedingly pilose, and simple in both sexes* : the tarsi with 

 their terminal joint rufo-testaceous.
