Coleoptera of the Falkland Islands. 179 



27. Listroderes compressiventris, Enderlein. 



Hah. FALKLANDS {Th. Havers, R. Vallentin), Seal Cove 

 and Port Louis {Enderlein), Port Stanley {Col. A. M. lltid, 

 M. Cameron). 



Described from three examples. The thirteen others in 

 the British Museum are mostly in poor condition, few of 

 them showing the pallid oblique streak on the sides of the 

 elytra towards the apex which is indicated in Enderlein's 

 figure. Recognizable amongst its allies by the apically 

 compressed, subacuminate, convex, elongate elytra, which, 

 viewed in profile, appear abruptly declivous at the apex, this 

 being due to the thickening of the suture before the tip. The 

 male has the first ventral segment deeply excavate down the 

 middle. There is an indication of a smooth median line on 

 the prothorax in all the specimens before me, including three 

 males. 



28. Listroderes nordenskioldf, Enderlein. 



I Jab. FALKLANDS, Port Darwin, Seal Cove, and Port 

 Stanley (Enderlein), W . Falkland (R. Vallentin). 



Described from nine examples, presumably all males.. 

 Two females before me seem to belong to this species, these 

 having the prothorax and under surface densely, finely punc- 

 tate, almost granulate, and the squamosity of the elytra 

 variegated with irregular rows of whitish spots, the cinereous- 

 hairs on the under surface long and adpressed. The apices 

 of the elytra are not produced. 



29. Listroderes griseonotatus, sp. n. 



<J . Elongate, moderately convex, dull above, shining 

 beneath, nigro-piceous, the antenna?, tarsi, and tips of the 

 femora ferruginous ; sparsely, finely griseo-pubescent, the 

 pubescence becoming closer at the sides of the elytra and 

 clustered into oblong spots on their disc, and also condensed 

 into a faint sinuous submarginal line on the prothorax ; above 

 densely, finely, shallowly, beneath very sparsely, punctate 

 Rostrum short, stout, a little widened outwards, rugosely. 

 confluently punctate, with a sharp median carina and an indica- 

 tion of another one on each side exterior to this. Head foveate 

 and somewhat depressed between the eyes, the antennal scape 

 reaching to a little beyond them, the vertex simply punctate. 

 Prothorax transverse, rounded at the sides, widest before the
