process. He also exhibited a collection of insects from South 

 Africa, including the following Orthoptera : — Pachytyliis 

 pardaliniis, which was often in such numbers as to be a 

 plague ; P. peregrimis, the North African species, which 

 extended its range, although not in great numbers, to the 

 South ; Cyytacanthacris purpurifera, a very large species ; a 

 mole cricket, Acheta africana, from Johannesburg, where 

 they are caught by the children to play with ; and an 

 immature specimen of the rock-hopper, Akicera carinata, 

 which is very sluggish in its habits, and apparently well 

 protected by its coloration ; a number of Coleoptera from 

 Pretoria, where thousands are attracted by the electric 

 light ; a few specimens of Hymenoptera, and a specimen of 

 the " queen moth," Armenia viimosce, from Pietermaritzburg, 

 where the larvae were more or less gregarious ; the imagines 

 congregated on particular shrubs, and could be easily 

 captured by the fingers, being very sluggish and seldom 

 seen to fly, 



Mr. Sauze exhibited a specimen of CicadeUa montana, one 

 of three taken in Surrey by Mr. Heasler, who had been 

 attracted by the unusual stridulation, and had beaten the 

 oaks from whence the noise proceeded. This fact was con- 

 sidered most important, as clearing up a doubt as to whether 

 the species did stridulate in this country, there being no 

 previous record of its having been heard to do so. 



Mr. West, of Greenwich, exhibited a short series of the 

 Hemipteron Eurygaster niaurus, a local species from Folke- 

 stone. 



Mr. Mansbridge exhibited a series of cocoons of Clisio- 

 cainpa neustria, one of which was double. When opened it 

 was found to contain two moths which had emerged from 

 the pupse, but which had been quite unable to get out of the 

 cocoon, because, it was suggested, they hindered each other's 

 attempts ; or, the cocoon being so large, they were unable 

 to concentrate their attacks upon the right part, and perhaps 

 could not get sufficient purchase for their feet and body. 



Mr. Barrett exhibited a variable series of Melanippe sub- 

 tristata and Hydrocampa nyinphealis, received from Mr. Boyd. 

 He also exhibited four British specimens of PUisia ni, with 

 an Italian example for comparison. Two belonged to Mr. 

 Jeffries, one of which was taken in Surrey, and one about 

 twenty years ago in Cornwall ; and two belonging to Mr. 

 C. A. Briggs, taken a few years ago also in Cornwall; a very 

 fine variety of Cleoceris viuiinalis, having the basal half of the 

 fore-wings very dark, in contrast to the pale outer portion ;
