248 Mr. T. V. Wollaston on certain Coleopiera 



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

 emarginatis : prothorace magno, subquadrato, antice latiore, postice 

 recte truncato (nee sinuato) ; lobo prosternali crasso, angusto, sub- 

 horizontali, retrorsum producto : mesosterno antice triangulariter et 

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

 AntenncB prothorace paulo breviores, apicem versus gradatim clavatse, 

 articulo 1""° (sub margine clypei recondito) 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). Labrum submembranaceum, ad latera tenuissimum, trans- 

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

 datis, apice paulo emarginatum et densissime pubescens. Mandihula 

 validse, corneae, triangulares, apice incurvse acutse et breviter bifidse, 

 intus in medio fissse coriacese. Maxill<s bilobse : lobo externa lon- 

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

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

 nato. Palpi maxillares sat elongati, articulo I'"" parvo, 2'^° majore 

 crassiore iutus sinuato-concavo, 3"'' breviore, ultimo sat magno sub- 

 securiforrai-ovali : labiates haud distincte observavi, Mentum fere 

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

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

 datim angustata subrobusta, apicem versus latior membranacea, 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 coUectionibus cum Tribolio conjunctum, sed a Tri- 

 holiis (i. e. ferrugineo 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 haud 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 coUateralis nisi oculo obliquo haud 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 

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

 et prsecipue tibiis dilatioribus, anticis latissime compresso-dilatatis.

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 Mediterranean 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.ferrugineum and madens) they are neverthe-
