90 Rev. H. S. Gorham on new Coleoptera 



The African 'J'riplacid genera will no doubt require revision 

 when they are better known ; at present the species described 

 as " Tnplax" are a medley. 



Mr. Marshall's examples of A. brunneus were taken at 

 light. 



Amblyscelis hcemorrJious. 

 A7nblyopus hccmorrhous, Gorham, Ann. Soc. Ent. Belg. vi. 1885, p. 326. 



Sanguinco-rufus ; elytris nigo-fuscis, puiicto humerali apiceque 

 iudeterminate rufis ; crebre punctatus ; chtris punctato-striatis, 

 opacis, interstitiis crebre permiuute punctulatis. 



Long. 5 millim. 



Hah. Natal, Estcourt [Marshall). 



There is sonietliing remarkable in the fact that I have 

 described an insect from India which I cannot separate 

 from this insect, and in writing that description I say: 

 ^' had this species been an African insect I should have re- 

 ferred it to my genus Amblyscelis, for the tibiae are angularly 

 widened." Mr. Marshall now sends three recent examples, 

 of the origin of which there can be no doubt, and except that 

 they are less shining than my Indian type, I can detect 

 no difference, 



Pycnogeusteria, gen. nov. 



Corpus oblougiim, nitidiim, punctatum, baud pubesceus. Oculi 

 concinne leviter reticulati. Antennae articnlo tertio duobus 

 basalibus superante, quarto ad octavum hand transversis, tribus 

 ultimis clavam oblougam formantibus, decimo ciim apicali 

 connato. Palpi maxillares articulo apicali triangulari valde 

 dilatato, labiales articulo ultimo oblongo parum dilatato, Pro- 

 notum fere ut in Amblijojw, tenuissime marginatum, prosterni 

 processu lato tequali opaco, antice baud elevato vol compresso. 

 Metasternum la^ve. Abdomen ajquale, leviter parce punctatum, 

 lineis nuUis. Pedes compressi ; femoribus sat latis ; tibiis valde 

 angulariter ad apicem dilatatis. 



The type of this new genus is a black insect with the 

 anteunsB, trophi, and body beneath, with the exception of the 

 head, prosternum, mesosternum, and mesothoracic epistoma, 

 bright luteous yellow ; the parts are so distinctly separated in 

 colour as to render it an easy object of study ; the mesothorax 

 may be piceous, but the yellow mesothoracic epimera are 

 peculiar. It will be observed that Pycnogeusleria approaches 

 both Amhlyopus and Amblyscelis ; from the former tbe almost 

 entire absence of raised lines on the abdomen (they are 

 distinct in A. vittatiiSj running across the segment) and the
