Genus Rhinocyllus. 

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

 16. Rhinocyllus hjprifomiis, n. sp. 

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

 squamosus et pilis suberectis cinereis sat rigidis obsitus ; protlio- 

 race rugose punctato, subrecto, postice vix angustiore ; elytris 

 cylindricis, punctato-striatis ; antemiis rufo-fcrrugineis, capitnlo 

 acuminate obscuriore ; pedibus rufo-piceis, subgracilibus. 

 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 

 siibcrect 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. Anthribidae. 

 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 truncate] ; oculis subrotnndatis antice anguste 

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

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

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

 ginato : scutello distincto : elyti'is sequalibus, postice obtuse trun- 

 cato-rotundatis, pygidium hand tegentibus. Antennce breves gra- 

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

 laterali insertoe, articulis 1™" et 2*^° (illo prsecipuc) longiusculis ro- 

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

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

 crassam triarticulatam efficientibus (9"° et 10'"° subpoculiformibus, 

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

 hrnm parvum, antice rotundatum. Pedes sat validi, jjosfici paulo 

 breviores : femorihus muticis : f arsis pseudetetrameris, articulis 1™° 

 et 2^*° longitudine subtequalibus, hoc apice leviter emarginato, tertium 

 prefunde bilobum recipiente, 4'° minutissimo, inter lobes tertii abs- 

 condito, ultimo clavato ungidcidis simplicibus munite.
