not a sexual mark [What spot ? — Ed.] . I exhibit living ova, larvfe, pups? 

 and imagines, and shall be pleased if members will help themselves to 

 what they require. The perfect insects sit with their heads considerably 

 raised, antennae lying along their backs, and the females with the 

 body bent upwards and the ovipositor protruding. They remain quiet, 

 except in the presence of the opposite sex, when they flutter wildly, 

 running round and round until copulation takes place. The period of 

 this extends to several hours. Stainton's sexual distinction of the 

 Kphi'stiae reads as follows : — ' Antennte of male not curved near the 

 base, in the male the base of the costa beneath with a tuft of hair.' " 



Messrs. J. A. Clark and Nicholson exhibited their series of Bombyx 

 QUERCus AND B. CALLUN.E to assist in illustrating a paper on those 

 species read by Capt. B. B. Thompson, who showed his own series, 

 and those of Mr. A. J. Hodges ; among the latter were two males, 

 supposed to be the var. roboria. Relating to Collecting observations, 

 Mr. J. A. Clark said that Ci/aniris an/ialus was well out at Epping 

 Forest, and Mr. Tutt said that he had seen Euchlni' cardaminea at 

 Hereford on April 10th. Mr. Bayne recorded a fresh specimen of 

 Taenioccuiipa inunda at the New Forest on May 3rd. Mr. May said 

 that an Erith correspondent, named Goddard, had found larviB of 

 Xi/.ssia Itisjddaria at Darenth and Chattenden Woods, feeding on 

 Spanish (or sweet) chestnut, but all except one were " ichneumoned." 

 Mr. Tremayne stated that he had a brood each of Aiiiidildasi/s strataria 

 and Knudiiios qucrcinaria feeding on Avhitethorn in separate jars. The 

 leaves which had been nibbled, or partly eaten, by the A. Hrataria, 

 had almost immediately turned brown round the edges and dried up, 

 while those which had been similarly treated by the E. quercinana 

 remained quite fresh. It was suggested that, in the case of the 

 A. strataria, the appearance ,might be caused by the action of some 

 liquid ('? acid) secreted in the mouths of the larvae, such liquid not 

 being present in K. qncrt-hiaria. 



Entomological Society of London. — May 6th, 1896. — Mr. Cham- 

 pion exhibited specimens of Aniara famdica, Zimm., from Woking, 

 Surrey, a recent addition to the British list. He also exhibited, 

 on behalf of Mr. Dolby-Tyler, a series of Eburia qu.\drinotata, 

 Latr., from Guayaquil, Ecuador, showing variation in the number of 

 the raised ivory-white lines on the elytra, there being sometimes an 

 additional mark exterior to the short basal line, and sometimes an 

 additional one on the inner side of the second line. Mr. Gahan said 

 he did not notice anything remarkable in the specimens except in the 

 arrangement of the spots. Mr. Horace Donisthorpe exhibited a 



SPECIMEN OF PtEROSTICHUS GRACILIS WITH THREE TARSI On OllC leg, 



taken near Weymouth last month. Mr. G. T. Porritt exhibited a 

 STKiKiNi; sKuiES OF Spilosoma menthastri which he had just bred from 

 Morayshire ova, the ground-colour of the specimens varied from the 

 usual white, through shades of yellow, and dark smoky brown. Mr. 

 Merriheld exhibited specimens of (iitnepti ri/.r rJiaiiDii bred from larvae 

 found in North Italy and Germany, the pvpje of which had been 

 suB.iKCTKi) to various temperatitres. Hc Said that high temperature 

 appeared to cause an increase of yellow scales in the female, and low 

 temperatures generally reduced the size of the orange discal spot on the 

 fore- wings of both sexes. He also exhibited some bred specimens of species 

 of Vanessids, the result of experiments tried with a view to ascertain the 

 extreme of high temperature that the pupae would bear, and its results.
