as regards species, — being not only a tritie larger, and more 

 parallel, than the T. Adamsi, but likewise a little more 

 dej)ressed, and of a conspicuously darker hue. Its rostrum 

 moreover is, if anything, somewhat longer, and more 

 appreciably (however minutely) punctulated ; and its scu- 

 tellum is perhaps a little longer, and more strictly 

 pentagonal in outline. 



(SUB-FAMILY COSSONIDES.) 



GENUS HIMATIUM. 



Wollaston, Trant. Ent. Soc, Land., 461 (1873). 

 Himatium variolosum, n. sp. 



H. angustulum, sublineare, depressiusculum, opacum, 

 piceo-nigrum, setulis grossis fulvo-cinereis subdemissis 

 parce obsitum ; capite fere ad oculos (demissos, sub- 

 inferiores, late separatos) immerso ; rostro angustulo, 

 parallelo, profunde et incequaliter punctato-rugoso ; pro- 

 thorace ovato-triangulari, antice conspicue constricto et 

 ibidem in medio calvo ferrugineo, grosse sed baud profunde 

 subreticulato-varioloso (nee punctato) ; elytris (prothorace 

 vix latioribus) parallelis, grosse punctato-striatis, inter- 

 stitiis parce et minutissime subgranulatis ; antennis 

 tarsisque piceo-ferrugineis, femoribus tibiisque rufo-piceis ; 

 tarsorum art. 3tio conspicue bilobo. 



Long. Corp. lin. circa 2. 



Habitat Africam Australem (sc. Promont. Bonae Spei), 

 a cl. E. W. Janson ad describendum missum. 



Ohs. A II. puhcscente (e regione " Malabar ") discedit 

 corpore paulo majore, obscuriore, magis opaco, setisque 

 robustioribus squamiformibus (nee pilis) pallidioribus 

 obsito ; prothorace grosse (sed liaud profunde) subreti- 

 culato-varioloso (nee punctato) ; tarsorumque art. 3tio 

 latiore et multo evidentius bilobo. 



Of the present well-defined Himatium three examples 

 have lately been submitted to me by Mr. Janson ; and 

 the species which they represent is manifestly very 

 distinct from the (South-Indian) H. piihescens, — not merely 

 in its rather larger size, darker hue, and more opake 

 surface (which is sparingly clothed with thicker, x)aler, and
