BRUCHIDiE. — RHINOMACER.

frequent decayed trees or flowers, and those of the second subsist 

 upon seeds of the leguminous kinds, to which they are sometimes 

 exceedingly destructive, especially the common pea, which is some- 

 times destroyed in vast quantities by the larvae of Bruchus Pisi, 

 hereafter described. The larvse of others are supposed to be para- 

 sitic upon insects. 



In Britain the following genera have been detected, which may 

 be thus cursorily characterized : 



Antenna; clavatae. 



/?Oi/?-M»i elongatum, angustum : . . 351. Rhinomacer. 



breve, latum. 

 Clava antennarum angusta, subacuminata : . 352. Anthuibus. 



abrupte-incrassata, subcompressa. 

 Ocull integres : corpus oblongum. 



Antenna; a.n^. 2-bus basalibus brevibus : . 353. Platyrhinus. 



elongalis: . 354. Tropideres. 



integres: cor/??« breviter ovatum : . 356. Brachytarsus. 



emarginati: antennce graciles : . • 355. Phloebius. 



.^H/en??ar filiformes, serratae aut pectinatae : . . 357. Bruchus. 



Genus CCCLI. — Rhinomacer, Fabricius. 



Antennas curved, long, inserted in the middle of the sides of the rostrum, 11- 

 jointed, the basal joint slightly robust and a little elongate ; the second shorter, 

 subnodose ; the six following slightly elongate and obconic ; the remainder 

 forming a loose slender club. Rostrum longer than the head, the base nar- 

 rovsrqd, rounded, the apex dilated: head transverse: eyes large, prominent: 

 thorax oblong, subcylindric : elytra rather soft, elongate, sublinear, moderately 

 convex, the apex of each rounded: /eg-* slender, unarmed : JeTOora slightly 

 incrassated : tibiw rounded, anterior a little curved : tarsi rather long. 



From the other genera of this family, Rhinomacer may be known 

 by the greater length and tenuity of its rostrum, of which the apex 

 is considerably dilated; the elongate, sublinear, soft, pubescent, 

 elytra; transverse head ; elongate tarsi, different structure of the 

 antennae, and general habit.

I may here take the opportunity of remarking that amongst the numerous 

 discoveries of species which have taken place during the last few months, 

 the following new British genera of Coleoptera have been communicated to
