326 Mr. C. 0. Waterhouse on new Cerambjcidse. 



apice anguste trancato, corjjore subtus parce punctulato, prosterno 

 elytrorumque marginibiis violaceis. 

 Loug. 10|-12 lin. 



Quite unlike any species known to me. In some respects 

 it calls to mind Amphisheta impressipennis in general colour, 

 the character of the spots, the slight truncature of each elytron, 

 the absence of any distinct anal plate, &c. ; but the shorter 

 form, expanded and concave under margins of the elytra, 

 oblige me to place it in the genus Coccinellojjsis. The broadest 

 part is about the luiddle ; and the insect is much narrowed 

 anteriorly and posteriorly. The thorax is longitudinally im- 

 pressed in the middle, and very lightly impressed on each 

 side ; moderately thickly and rather finely ]junctured. The 

 elvtra have no distinct slioulders ; that is, they are at the base 

 not wider than the thorax, and gradually become wider to the 

 middle ; the discoidal area before the middle is very convex, 

 the sides slope down, and the apical portion slopes down very 

 much ; the margins are not at all retlexed, finely punctured ; 

 there are fine punctured lines on the dorsal region ; there are 

 numerous small ])ilose |uinctured impressions (particularly 

 posteriorly), and there are three rather larger round spots on 

 each elytron, one below the slight humeral callosity, one about 

 the middle, and another between that and the apex. On the 

 underside, the sides of the sterna and the posterior coxas are 

 of a more brassy colour. The prosternal process and the 

 middle of the metasternum are almost without punctures, flat, 

 and of a purple colour. The abdomen is sparingly punctured, 

 very shining, finely pilose at the sides ; the apical segment is 

 sparingly punctured, about as long as broad, triangular, with 

 the apex rounded. The under margins of the elytra are 

 violet, with a reddish-brown tint at the base. 



Cerambycidse. 



Artelida aurosericea. 



Flava, dense anreo-pilosa ; antciinis fuscis, clytrorum apice parum 



infuscato ; tibiis posticis ad apicem dilatatis, hirsutis. $ .

This species is close to A. crinita^ Th. (Syst. Ceramb. 

 p. 14o), but differs in being of a brighter yellow, clothed with 

 moie golden pubescence, in having the antennae brownish (ex- 

 cept at the base) ; the abdomen is yellow ; and the apical half 

 of the posterior tibije is also yellow and rather less dilated. 

 The lateral tubercles of the thorax are short and conical ; there 

 are four tubercles on the dorsal region, but they are very slight 

 and obtuse. The elytra are obtuse at the apex, but not dis-
