(Subfam. Phylacides.) 

 Genus Trichosternum (nov. gen.). 



Corpus sat magnum, ovato-oblongum : fronte ad latera leviter ele- 

 vata, ad apicem profunde biloba ; oculis antice valde emarginatis : 

 prothorace transverse, antice leviter emarginato, postice bisinuato, 

 ad latera vix explanato : scutello magno, semicirculari-triangulari : 

 sternis abdominec[ue fere ut in Hadro, sed lobo prosternali valde 

 setose et anguste marginato : elytris subconnatis : alls obsoletis. 

 Antennce capitis prothoracisque longitudine, robustse, apicem versus 

 leviter incrassatse, articulo 1'"° sat robusto breviusculo, 2^° brevi, 

 3*'° elongate, 4'° hoc breviore, 5'° G'°que quarto paulo brevioribus 

 inter se sequalibus, reliquis quinque paulo crassioribus (ultimo trans- 

 verso-rotundato). Labrum (sat anomalum) magnum, corneum, ro- 

 bustum, crassum, ad latera rugose insequaliter serratum, rotundato- 

 quadratum et quasi e laminis duabus (una ad alteram arete applicata) 

 efFormatum, supera sc. robustiore et apice profunde biloba (necnon 

 per emarginationem parce ciliata), infera ad angulos anticos dense 

 ciliata et apice calva minus excavata (ergo superne, inter lobos partis 

 superioris, conspicua). Mandibidce validissimse, corneae, crassse (ad 

 basin prtesertim valde incrassatse), triangulares, apice multo inflexae 

 et obtuse bifidse, intus in medio fissse coriacea;. Maxillae bilobse : 

 lobo externo pubescente, setoso ; interno multo breviore, apice in- 

 fiexo acuto, intus longe pectinato-setoso. Palpi maxillares articulo 

 jmo parvo extus sinuato, 2''" elongato subclavato, 3''" breviore, ul- 

 timo magno securiformi : labiates articulo 1"'° parvo, 2'^" niajore 

 crassiore clavato, ultimo hoc crassiore subovato. Mentum corneum, 

 rotundato-quadratum, basi paulo angustatum, apice integrum, angulis 

 anticis rotundatis. Ligida apice vix emarginata, angulis anticis ro- 

 tundatis longissime setosis. Pedes robusti, crassi : tibiis (prsesertim 

 posterioribus) dense setulosis, anticis ad apicem distincte dilatatis : 

 tarsis heteromeris, posterioribus (sed preesertim posticis) articulo 1""" 

 longiusculo. 



Obs. Genus Hadro proximum ; sed scutello majore, corpore minus 

 glabro (prostcrni lobo densissime setoso), labro valde anomalo du- 

 plici, mandibulis crassioribus, mento siinplici (nee e laminis duabus 

 formate), pedibus robustioribus tibiisque anticis multo magis dila- 

 tatis, prseter csetera, ab Hadro differt. 



A Qpii,, pilus, et areptov, pectus (i. e. lobus prosternalis). 



The beetle from which the above details have been compiled 

 is well known in many of the more extensive collections, where

 title of " Phylax validus, Dej.,'^ and Prof. Lacordaire informs me 

 that he also possesses it under the same ; but it is not included, 

 as such, in Dejean's Catalogue, whilst a glance at the structural 

 diagnosis will be sufficient to show that it is no Phylax at all 

 (as now restricted and defined). It has also been lately com-
