Blab'motus is an exceedingly well-marked genus, presenting many peculiarities 

 which ^vlU readily separate it from the allied groups. Thus, its extremely pUose 

 surface and cylindrical hody (which however it possesses iu common with Tricho- 

 ferus), added to the structure of its prothorax, which has two prominent, greatly 

 developed tubercles on the disk, and the sides furnished \d\\\ an acute central 

 tooth, are, even 2)rimd facie, apparent : whUst, at the same time, in its obscurer 

 details it is not less distinctly characterized, — since its reniform eyes (somewhat 

 remote from the inner margin of which the antennae are inserted, which is not the 

 case cither in JPhijmatodes or Trichoferus), and the remarkable formation of its 

 very elongated palpi, which have theu* last joint large and seciu-iform and the basal 

 maxillary one decjily* sinuatcd externally, at once remove it from the remainder 

 of the Madeii'an Longicorns here desci'ibed. I have retained the name proposed 

 for it by M. Chevrolat, after my first return from the Madeira Islands in 1818. 



327. Blabinotus spinicollis, Woll. (Tab. IX. tig. l.) 



B. subcylindricus fusco-piceus valde cinereo- et flavescenti-cinereo-pubescens, prothorace inaequali 

 tuberculato ad latera spina media instructo, clytris profunde punctatis piloso-marmoratis, 

 antennis pedibusque fusco-ferrugineis. 



Long. Corp. lin. 5-7,}. 



Habitat in ligno antiquo per partem Maderae sylvaticara, non infrequens : praesertim nocte volitat, quo 

 tempore ad ignium lumina allectus saepissime legatur. 



B. narrow, linear-elongate, subcylindrical, of an obscure rusty- or brownish-piceous, densely clothed 

 with decumbent, silken, cinereous and yellowish hairs, and with longer and more erect ones 



* This singularity- of structure is slightly indicated also in Clytus, but altogether absent in the inter- 

 mediate genus Trichoferus. In Beucalian it is exceedingly evident.
