Longicorn Coleojytera. 205 



free angle above tlie bulb of antenna ; antennas a little 

 longer than body (in the male?) pubescent and slightly 

 pilose, none of the joints with sharp angles, 1st joint 

 rather stout, but little more than half as long as the 3rd 

 joint; joints 4 to 11 not differing much from one another. 

 Ligula (?) ; terminal joints of palpi distinctly dilated. 

 Anterior coxffi globose, very little prominent, their cavities 

 Avithout external prolongation, but with the suture of its 

 closing quite distinct, their posterior portion open ; middle 

 coxal cavities with a veiy small external prolongation. 

 Legs rather short and stout, femora much thickened, but 

 without distinct slender basal portion. Surface of thorax 

 rather flattened and uneven, without distinct prominences 

 or marks. 



I am indebted to Mr, Bates for an insect from Formosa, 

 which is extremely closely allied to this Astrimus obscurus, 

 but is a little larger and paler in colour. I should, how- 

 ever, have considered the two to be conspecific, were it 

 not that an undoubted, though minute, difference exists 

 in the external prolongation of the intermediate cotyloid 

 cavities ; the anterior prolongation of the side of the 

 metastermim is conspicuously shining, and is deflexed 

 from the plane of the rest of the metasternum. As I have 

 not been able to assign the species to any named genus, 

 I have given it a new generic name, and enumerate its 

 characters above. It cannot, I think, be very much mis- 

 placed in Lacordairc's Callidiopsidcs, although the an- 

 tennal tubers are rather strongly elevated and distinctly 

 anofulated. 



SoTENUS (ncAv name). 



• Sotenus setiger, n. sp, Fulvo-testaceus, fere unicolor, 

 sat nitidus, vertice summo transversim scabroso ; jn-otho- 

 race subgloboso, sed dorso sat planato, leviter intequali, 

 nitido, fere nudo, punctis panels sctigeris irregulariter 

 sparsis ; elytris punctis profundis sat magnis, subseriatis 

 ornatis, seriebus alternis setis erectis, tenuibus elongatis 

 munitis. Long. 11^ mm., lat. 3 mm. 



This insect is rather remarkable on account of the 

 sculpture of the back of the head and of the punctuation of 

 the elytra; the general form, appearance and colour are 

 somewhat like Liuderes Kollari, but iSutenus setiger is 

 more robustly formed.
