248 Mr. T. V. Wollaston on certain Coleopiera 



tera vix elevata, ad apicem rotuiidata integra ; oculis antice valde 

 emarginatis : protJiorace magno, subquadvato, antice latiore, postice 

 recte truncato (nee siuuato) ; loho irrosternuU crasso, angusto, sub- 

 horizontali, retrorsum producto : mesosterno antice triangulariter et 

 sat argute cxciso ; scutello sat magno, semicirculari-triangulari. 

 Antennce prothorace paulo breviores, apicem versus gradatim clavatae, 

 articulo 1""° (sub margine clypei recondite) elongato valde bicurvato 

 apice sat robusto, 2'^" breviore paulo angustiore, 3''" ad 6*""^ minori- 

 bus subsequalibus latitudine vix crescentibus, reliquis clavam mag- 

 nam laxam minus abruptam 5-articulatam efficientibus (ultimo sub- 

 globoso). Labinim submembranaceum, ad latera tenuissimum, trans- 

 verso-quadratum, postice gradatim angustius, angulis anticis rotun- 

 datis, apice paulo emarginatum et densissime pubescens. Mandibnlce 

 validse, corneee, triangulares, apice incurvte acutae et breviter bifidse, 

 intus in medio fissse coriacese. Muxillce bilobse : loho externa lon- 

 gissimo, subovato, pubescente, ad apicem ipsum inflexo et etiam sub- 

 armato ; interno brevissimo, apice inflexo pubescente sed baud unci- 

 nato. PaJjoi maxillares sat elongati, articulo 1™° parvo, 2^^° majorc 

 crassiore intus sinuato-concavo, 3''° breviore, ultimo sat magno sub- 

 securiformi-ovali : labiales hand distincte observavi. Mentum fere 

 ut in Halonomo, i. e. transverso-quadratum, postice gradatim angus- 

 tius et antice late emarginatum. Liyula obtriangularis, postice gra- 

 datim angustata subrobusta, apicem versus latior mcmbranacea, an- 

 gulis anticis subangulato-rotundatis, apice valde pubescens integra. 

 Pedes validi, antici fossorii : tibiis parce setulosis, anticis valde, 

 posterioribus minus (sed distincte) compresso-dilatatis, anterioribus 

 (sed prsesertim anticis) per marginem externum minute crenulatis : 

 tarsis heteromeris, posticis articulo 1™° longiusculo. 



Obs. Genus in collectionibus cum Tribolio conjunctum, sed a Tri- 

 holiis (i. e. ferrngineo et madenti) species hujus generis toto coelo 

 recedunt ; non solum fossorii sunt (per oras maritimas arenosas sub 

 confervis vel in locis valde salinis degentes), prothorace multo majore 

 antice lato basi baud sinuato clypeoque ad latera minus elevato nec- 

 non ad apicem rotundato (nee emarginato), sed lobo prosternali ma- 

 jore crassiore sublineari-angusto (nee spatuliformi), mesosterno in 

 medio profundius et argutius triangulariter exciso, mandibulis ad 

 apicem brevius bifidis [apex collateralis nisi oculo obliquo baud ob- 

 servandus], mento apice late emarginato, ligula recte truncata, maxil- 

 larum lobo externo multo longiore elongato-ovato loboque interno 

 breviore magis curvato inarmato, antennis facilius incrassatis (clava 

 i)- nee 3-articulata), articulo basilari multo longiore et valde curvato, 

 et praecipue tibiis dilatioribus, anticis latissime compresso-dilatatis. 



A xpevciis, fictus, et Stene (Coleopterorum genus). 



The few closely-allied beetles for the reception of which I 

 have erected the present genus appear to belong principally to 

 African or the more southern ]\Iediterranean latitudes, and are 

 usually to be found in cabinets (when existing there at all) 

 associated with Triholium, from the only two described exponents 

 ^of which (viz. the T.ferrughieum and madens) they are neverthe-
