Longicornia. 
Acanthoderes Kidleyi, n. sp. 
Latus, depressus, omnino albo-griseo-pubescens ; elytris poue 
medium macula laterali inconspicua ornatis ; 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 antennae, 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 . jcispiclea. 
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. A.] 
Trypanidiijs isolattts, n. sp. 
Dense pallide griseo-pubescens ; thorace guttis minutis non- 
nullis ornato ; elytris nigro-punctatis. 
Long. 13-15 millim. 
Closely allied to r l\ dimidiates, Th., but relatively a little nar- ' 
rower and quite differently coloured. The pubescence is very
