THE ENTOMOLOGIST. 117 



whenever they carae in contact, and if they touched a wound 

 caused severe inflannnation and painful ulcers, Mr. Bates 

 expressed a doubt as to whether the small birds would care 

 to meddle with them. 



[The beetles here s])oken of as producing inflammation and 

 ulcers are in all probability species of Lytta and Epicauta, 

 and not members of the family Chrysomelida), to which 

 Doryphora 10-lineata belongs. — Edward Newman.] 



Musical Orthoplera. — Mr. M'Lachlan exhibited two male 

 examples of an Orthoptcrous insect, belonging to ihe family 

 LocustidiE, 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 |)eitain 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. 



Oiiiscigaster IVakefieldi. — Mr. M'Lachlan also exhibited 

 a series of examples illustrating the natural history of 

 Oniscigasler 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. 



Jfjualic Arctia Larva. — Mr. M'Lachlan further remarked 

 that in the Bulletin of the Proceedings of the French Ento- 

 mological Society, at the Seance of the 28th January last, 

 M. Guenee avowed himself much puzzled concerning the 

 supposed aquatic larva producing a species of moth, described 

 by AL Bar as Palustra Laboulbenei, which he considered was 

 allied to the genus Cnetliocampa. 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.
