INSECTA MADERENSIA. 385" 



either tlie 0. ventrosus or tlie O. cenescens, — its excessively minute scutellura, Lu 

 connection with its inflated and ahnost impubescent form, calling to mind some of 

 the Omiades of more northern latitudes. Still, in the structure of its rostral 

 groove and antennae, it agrees better with the Madeiran type through which we 

 have just passed, and which descends (liable to sul)sidiary modifications) from 

 Laparocerus and Atlantis, through the aberrant Atl an tides, until its distinctive 

 features are almost lost sight of in these smaller groups. It is a common insect on 

 all the mountain- slopes of Madeu'a, between the Hmits of from 2000 to 5000 feet 

 above the sea, but is perhaps most abundant about midway between those 

 extremes. It occurs throughout the whole year, though more particularly during 

 the winter and spring, — at which seasons I have observed it in great profusion on 

 the grassy decli^dties of the Curral das Ereii'as, and on the exposed ridges above 

 the Allegria and Sao Roque. I have however captured it on the Lonibo das Vacas 

 in June, at the Cruzinhas and the Fanal in Jiily, and at the Eeijaa de C6rte in 

 August. It exists likewise on the Dezerta Grande, where it will be perceived, from 

 the above diagnosis, that the specimens assume a distinct state peculiar to that 

 island, — and where, dm'ing January 1849 and May 1850, I collected a series of 

 examples from beneath stones on the great western promontory. I have dedicated 

 the species to my friend G. E.. Waterhouse, Esq., of the British Museum, whose 

 long attention to the Curculionidce is well known, and to whom I am indebted for 

 much valuable assistance in the comparison of the insects of this work. 



Genus 125. ANEMOPHILUS, WoU. (Tab. VII. fig. 7, 9.) 



Corpus parvum, ovatum, convexum, pube variegatum : 7-ostro et scrobe ut iu genere prsecedenti, seel 

 illo paulo breviore, vix oculos attingente, et postice minus piano ; oculis minutis subrotnndatis 

 demissis : prothorace ad latera sub?equaliter rotundato : scutello vel minutissimo vel distincto : 

 " elytris subconnatis, ad humeros rotundatis : alls obsoletis. Antemice (VII. 7 a, 9 a) breves crassse ; 

 scapo cm-vato, ad apicem clavato; funiciilo 7-articiilato, articulo primo magno crasso obconico, 

 secundo minore, reliquis brevibus subnodosis; clava ovata, obscure articulata. Pedes breves 

 robusti : tibiis in utroque sexu similibus et apice valde setuloso-ciliatis ; anticis apicem versus 

 dilatatis, ad apicem internum leviter incurvis, ad externum vel truncatis vel acutis ; posterioribus 

 (VII. 7 b, 9 b) ad apicem subito plus minusve dilatatis, angulis iuterno et extemo subsequalibus 

 acutis. 



Ab avefMo^ ventus, et cf)tXo<; amicus. (Typus — Anemophilus crassus.) 



The three singular little insects which I would include imder the present genus, 

 possess so many peculiarities of theu* own, that it is impossible to admit them, 

 even as a separate section, into Omias, the distinctive modifications of then* un- 

 usually short and thick limbs receding altogether from the corresponding details 

 of the Omiades (as represented in Madeira), and seeming to imply, apart from 

 minor differences, that they are correctly treated as members of an independent, 

 though nearly allied (and, to a certain extent, subsidiary) group. As regards
