LONGICORNIA. 

 ACANTHODERES ElDLETT, D. sp. 



Latus, depressus, omnino albo-griseo-pubescens ; elyfcris pone 

 medium macula lateral! inconspicua oruatis ; apice mucro brevi 

 instructo. 



Long. 11|-16 millim. 



Form and general appearance of A. Jaspicea, Germ., but a little 

 more depressed and with the elytra rather more obtuse at the 

 apex. The colour is pale whitish grey, generally with some sandy- 

 yellow shade on the base of the antennsD, disk of the thorax, and 

 on parts of the elytra. The front of the head is paler, with some 

 conspicuous black punctures, especially between the eyes. The 

 thorax has the usual median raised line and slight swelling on 

 each side of the disk ; there is no black at the sides ; there is a 

 line of very distinct black punctures along the basal margin, and 

 a similar (but less regular) line along the front margin, and there 

 are some other punctures scattered over the surface. The elytra 

 have the usual costa distinct, slightly sinuous as in A. jaspidea. 

 On the shoulder a few small tubercles may be traced through the 

 pubescence. Some examples have scarcely any trace of spots, 

 but most have a not very conspicuous pale fuscous spot behind 

 the middle near the side, and behind this there are generally 

 numerous black punctures which are surrounded by a brown 

 shade ; usually a short oblique brown line may be seen at the 

 apex of the costa. Apical mucro shorter and less acute than in 

 A. jaspidea. Abdomen with a slight grey shade in the middle, 

 and a line of black dots on each side. Tibiae unicolorous, or with 

 a very slight pale brown spot near the apex. Some examples 

 have a slight oblique brown spot on the disk, rather before the 

 middle. 



[These flew into light in the evening, and were very plentiful. 

 They made a loud squeaking noise when caught. — H. N. B.l 



Trypanidius isolatus, n. sp. 



Dense ])allide griseo-pubescens ; thorace guttis minutis non- 

 nullis oriiato ; elytris nigro-punctatis. 

 Long. 13-15 milliui. 



Closely allied to T. diniidiatits, Th., but relatively a little nar- 

 rower and quite differently coloured. The pubescence is very
