4,28 INSECTA MADERENSIA. 



conspicuous ; and the eyes, instead of being reniform, are almost as deeply emar- 

 ginated as in any of the CerambicidcB with which we have here to do. Its antennae 

 moreover are not quite so hau-y as in Slabinotns (though its body is even more 

 so), and its femora are much less clavate. In some respects indeed it is inter- 

 mediate between Blabinotiis and Cli/ttis, uniting to a certain extent the elements 

 of them both : nevertheless, whilst the above distinctions will readily separate it 

 from the first, its elongated, cylindrical body, apically entire elytra, more length- 

 ened and setiform antennae (inserted immediately in front of the emargination of 

 the eyes), in conjimction with its less perceptibly abbreviated anterior legs, wUl, 

 apart from the modifications of its oral organs, equally remove it from the second. 

 The two ol)scure patches of its prothorax, produced by the condensation of paler 

 pile, are worthy of remark ; for, being placed in nearly similar positions as the 

 tubercles are in BlaUnotus, they have all the appearance, prima facie, of being 

 elevated, likewise, — thus keeping up the analogy of the latter in a somewhat 

 singular way. 



328. Trichofems senex, WoU. (Tab. IX. fig. 3.) 

 T. subcylindricus fusco-piceus valde subcinereo-pubescens, prothorace transverso-subgloboso aequo 



obscure piloso-bimaculato, elytris punctatis piloso-submarmoratis, antennis pedibusque rufo-fer- 



rugineis. 

 Long. Corp. lin. 4:^-7. 

 Habitat in JIadera sylvatica, rarissime : duo specimina (a DD. Heinecken at Lowe capta) sola vidi. 



T. nanow, linear-elongate, subcyliiulrical, of much the same colour as the last insect, but a little 

 more nifcscent, clothed with decumbent subcinereous hairs (of a coarser nature, and with a less 

 decided admixture of yellow, than in the last insect), and with exceedingly long and almost erect 

 ones intermixed. Antenme just perceptibly shorter than in Blahinotus, and not quite so hirsute. 

 Prothorax somewhat transverse-globose, its sides being regularly rounded ; its upper surface free 

 from inequalities and tubercles, though with indications of a glabrous and very abbreviated por- 

 tion of an (otherwise) obsolete dorsal line in the centre of its hinder disk ; and with an ob.scui-e 

 patch, produced by denser pile, on either side of its fore disk. Elytra rather roughly punctured 

 anteriorly, but obsoletely so behind (the punctures even in front being less defined than those 

 of BlaUnotus) ; with the cinereous pubescence somewhat unequally distributed (though scarcely 

 causing the surface to appear so decidedly mottled as in the last genus) ; and with excessively 

 long, fine, and erect hairs interspersed. Antenna and legs rufo-ferruginous. 



Until quite recently a single specimen only of the present insect (collected by 

 the late Dr. Heinecken) had come beneath my notice ; but a second has been just 

 communicated l)y the llev. R. T. Lowe, by whom it was detected at the llibeiro 

 Frio during Jidy of 1851. It would seem to be extremely rare, — having alto- 

 gether escaped my own observations in these islands (the result however perhaps 

 of its not making its appearance until nearly the autumn, a season at which my 

 researches in Madcu-a have been less prosecuted than at any other).
