Genus Rhinocyllus. 

 Germar, Neue Wetter. Annal. i. 137 (1819). 

 16. Rhinocyllus lypriformis, n. sp. 

 R. angustus, lineari-cylindricus, piceo-niger, dense flavescenti-cinereo- 

 squamosus et pilis suberectis cinereis sat rigidis obsitus ; protho- 

 race rugose punctate, subrecto, postice vix angustiore ; elytria 

 cylindricis, punctato-striatis ; antennis rufo-ferrugineis, capitulo 

 acuminate obscuriore ; pedibus rufo-piceis, subgraciiibus. 

 Long. Corp. lin. If. 



Most closely allied to the R. Lareynei, Jacq. Duval (which I 

 have received from M. Leon Fairmaire of Paris, and for the loan 

 of four additional specimens of which I am indebted to M. Jekel), 

 a species found at Montpellier, &c., in the south of France, but 

 altogether narrower and more elongate, with its elytra not quite 

 so wide just behind their humeral angles (where they are but 

 very slightly broader than the base of the prothorax), with its 

 suberect bristles shorter and less dense, and with its legs a trifle 

 less robust. It is possible, indeed, that it may be only a geo- 

 graphical phasis of that insect. In general outline it is a little 

 suggestive of the Lyprus cylindricus, from which circumstance 

 I have borrowed its trivial name. It is hitherto unique, a single 

 example only having been captured at St. Vincent by Mr. Fry. 



Fam. Anthribidse. 

 Genus Trigonorhinus (nov. gen.). 



Corpus sat parvum, breviter oblongum, densissime pubescenti- 

 variegatum : rostro brevissimo, subtriangulari, basi lato, apicem 

 versus angustiore et ad apicem ipsum bisinuato-rotundato [baud 

 emarginato, nee etiam truncato] ; oculis subrotundatis antice anguste 

 emarginatis, demissis : prothorace convexo, aequali (nee tuberculato, 

 nee strigato), subconico, postice lato et ibidem fere elytrorum latitu- 

 dine, margine postico (necnon laterali versus basin) anguste mar- 

 ginato : scutello distincto : elytris aequalibus, postice obtuse trun- 

 cato-rotundatis, pygidium baud tegentibus. AntenncB breves gra- 

 ciles, apice abrupte et valde clavatse, infra sinum oculorum in fovea 

 laterali insertae, articulis l"*" et 2''° (illo prsecipue) longiusculis ro- 

 bustis, reliquis ad clavam parvis latitudine subsequalibus (3*'" quarto 

 vix longiore), 9°°, 10™° et 11""° clavam magnam valde abruf)tam 

 crassam triarticulatam efficientibus (9"° et lO'"" subpoculiformibus, 

 hoc paulo latiore transverse, ultimo subovato basi truncato). La- 

 brum parvum, antice rotundatum. Pedes sat validi, postici paulo 

 breviores : femoribus muticis : tarsis pseudotetrameris, articulis 1™° 

 et 2^° longitudiue subsequalibus, hoc apice leviter emarginato, tertium 

 profunde bilobum recipiente, 4*° minutissimo, inter lobos tertii abs- 

 condito, ultimo clavato unguiculis simplicibus munito.
