REPORTS OF SOCIETIES. 



ENTOMOLOGICAL SOCIETY OF LONDON. 



November 2nd, 1887. — Dr. David Sharp, F.Z.S., President, in the chair. 



Mr. Stevens exhibited a specimen of Acidalia immorata, L., purchased by 

 him some years ago at the sale of the collection of the late Mr. Desvignes. 

 Mr. Stevens remarked that specimens of the insect lately captured near Lewes 

 had been described last month by Mr. J. H. A. Jenner as a species new to 

 Britain. 



Mr. Adkin exhibited, and made remarks on, a series of male and female 

 specimens oiArctia mendica from Co. Cork; he also exhibited for comparison 

 two specimens of A. mendica from Antrim, and a series of bred specimens 

 from the London district. Some of the males from Cork were as white as the 

 typical English females, but the majority of them were intermediate between 

 the form last mentioned and the typical English form of the male. 



Mr, Enoch exhibited a specimen of Calocoris bipunctatus containing an 

 internal parasitic larva. 



Dr. Sharp exhibited three species of Coleoptera new to the British list, 

 viz.:—(l) Octhebius auriculatus, Eey, found by Messrs. Champion and 

 Walker some years ago in the Isle of Sheppey, but described only quite re- 

 cently by M. Eay from specimens found at Calais and Dieppe. (2) Limnius 

 rivularis, Eosenb., found by the late Dr. J. A.. Power at Woking ; the 

 species though not uncommon in Southern Europe, had not, he believed, been 

 previously found farther north than Central France. (3) Tropipkorus obtusus, 

 taken by himself on the banks of the Water of Cairn, Dumfriesshire ; he had 

 considered previously that this might be the male of T. mercurialis, but M. 

 Fauvel, who was studying the European species of the genus, informed him 

 that this was not the case. Dr. Sharp also exhibited a Goliathus recently de- 

 scribed by Dr. 0. Nickerl as a new species under the name of G. atlas, and 

 remarked that the species existed in several collection, and had been supposed 

 to be possibly a hybrid between G. regius and G. cacicus, as its characters 

 appeared to be exactly intermediate. He also exhibited a living example of 

 the Mole Cricket, Gryllotalpa vulgaris, from Southampton ; between the 

 spines of its hind legs were a number of living Acaridse placed in a symmet- 

 rical manner so as to appear as if they formed a portion of the structure of 

 the limb. 



Mr. Eland Shaw exhibited two species of Orthoptera, which had been un- 

 usually abundant this year, viz. Nemobius sylvestris, from the New Forest, 

 and Tettix subulatus, from Charmouth, Dorset. 



Mr. E, B. Poulton exhibited the cocoons of three species of lepidoptera, in 

 which the colour of the silk had been controlled by the use of appropriate
