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

 when they are better known ; at present the species described 

 as " Tri)>lax " are a medley. 



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

 light. 



Amhlyscelis hoimorrhous. 

 Amblyopus hamorrhous, Gorham, Ann.Soc. Ent. Belg. vi. 1885, p. 326. 



Sangninoo-rufus ; elytris nigo-fusois, puncto humerali apiceque 

 indeterminate riifis ; crebrc punctatus ; elytris punctato-striatis, 

 opatis, interstitiis crebrc permiuute ijunctulatis. 



Long, 5 millim.

There is something 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 Amhlyscelis, 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. 



Pycnogeustekia, gen. nov. 



Corpus oblougum, nitidnm. pmictatum, hand pubesceus. Oculi 

 concinne leviter reticulata Antennae articnlo tertio duobus 

 basalibiis supcrante, quarto ad octaviim baud transversis, tribus 

 ultimis clavam oblougam formantibus, dccimo cum apicali 

 connato. Palpi niaxillares articulo apicali triangulari valde 

 dilatato, labiales articulo ultimo oblongo parum dilatato. Pro- 

 notum fere ut in Amlihjojio, tenuissime marginatum, prosterni 

 processu lato asquali opaco. anticc baud elevato vel compresso. 

 Metasternum l;eve. Abdomen a^qualc, leviter parce punctatum, 

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

 angulariter ad apicem dilatatis. 



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

 antennaj, 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 Pycnogeusteria apju-oaches 

 both Amhhjojjus and Aviblyscelis ; from tiie former the almost 

 entire absence of raised lines on the abdomen (they are 

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