THE ENTOMOLOGIST. ILly/ 
whenever they came in contact, and if they touched a wound 
caused severe inflammation and painful ulcers, Mr. Bates 
expressed a doubt as to whether the small birds would care 
to meddle with them. 
[The beetles here spoken of as producing inflammation and 
ulcers are in all probability species of Lytta and Epicauta, 
and not members of the family Chrysomelide, to which 
Doryphora 10-lineata belongs.— Edward Newman. | 
Musical Orthoptera.—Mr. M‘Lachlan exhibited two male 
examples of an Orthopterous insect, belonging to the family 
Locustide, which had been placed in his hands by Mr. Daniel 
Hanbury, who received them some years since from his 
brother at Shanghai. It appeared from Mr. Hanbury’s 
statements that these insects were sold in the streets of 
Shanghai, confined in little ornamental wicker-cages, and 
bought for the sound they produced. ‘The species appeared 
to be undescribed, and to pertain to a new genus, somewhat 
allied to Xiphidium. The President remarked that in Turkey 
a kind of cricket was kept in a similar manner in paper cages, 
and fed upon lettuce-leaves. 
Oniscigaster Wakefieldi.—Mr. M‘Lachlan also exhibited 
a series of examples illustrating the natural history of 
Oniscigaster Wakefieldi from New Zealand. He _ had 
recently received from Mr. Wakefield a second series of 
specimens, including the male imago, female sub-imago, 
adult nymph, and larva. The lateral wing-like horny expan- 
sions of the terminal segments of the abdomen in the imago 
and sub-imago are continued in the aquatic conditions on each 
segment of the abdomen, and in addition there are similar 
formations along the back of the abdomen placed longitudi- 
nally and vertically. 
Aquatic Arctia Larva.—Mr. M‘Lachlan further remarked 
that in the Bulletin of the Proceedings of the French Ento- 
mological Society, at the Séance of the 28th January last, 
M. Guenée avowed himself much puzzled concerning the 
supposed aquatic larva producing a species of moth, described 
by M. Bar as Palustra Laboulbenei, which he considered was 
allied to the genus Cnethocampa. He thought further in- 
formation very desirable, for all the characters of the insect 
were opposed to aquatic habits in any stage ; and he suggested 
that the bubbles of air entangled in the hairs might be only 
expired air.
