Hope Museum, Oxford. Pupa found 7th July, 1899, fly emerged 12th 

 of the same month. Schiner records Anthrax as being parasitic in the 

 larvae and pupae of Lepidoptera and Hymenoptera. Dr. Sharp states 

 that M. Kiiuckel d'Herciilais bred Anthrax fenestralis [fenestrata?) 

 from the egg-case of a large locust, Ocnerodes sp. He also exhibited 

 (b) Tabanus bromius — pupa found as above, emerged 12th July, 1899, 

 observing that Tabanus is generally supposed to breed in wet mud 

 round the margin of pools ; and (c) a new species of Cordylura, of 

 which five males and five females were taken at Aviemore in July, 

 1899, and further specimens again in abundance in the same place 

 June, 1900. Col. Yerbury mentioned also that he had sent some of 

 them to Herr Th. Becker in Silesia, in the hope that the species would 

 have received ere now a distinctive name. — Mr. L. B. Prout exhibited 

 three male specimens of Proutia betulina, Z., and two of P. eppingella, 

 Tutt, bred from larvae taken this season in Epping Forest. He re- 

 marked that both species occurred in the same part of the forest, and 

 the larvffi appeared to be attaclied chiefly to old hawthorns. Excepting 

 in the smaller size of P. eppingella, no superficial difference was ob- 

 servable between the two species. The specimens of P. betulina, 

 however, emerged about ten days earlier, the dates being July 5th, 8th, 

 and 9th, while P. eppinyella appeared between July 14th and 21st. 

 Dr. Chapman said that, accepting provisionally Mr. Tutt's name of 

 eppingella for the last species, as a way of avoiding the difficulty of 

 determining whether it be the salicolella of Bruand or his anicanella, 

 which seems more probable, or a distmct species, he might call 

 attention to the fact that he knew of no other British males of the 

 species, except one previously bred by Mr. Prout, and one of unknown 

 locality in Dr. Mason's collection. It is at once distinguishable from 

 P. betulina by the numerous joints to the antennae (27 instead of 21-24, 

 24 instead of 18-21, if only the joints visible by their pectination out- 

 side the head clothing be counted), which are nevertheless shorter, and 

 by the shortness of the anterior tibi^ (-21 mm. instead of -29 mm.), as 

 well as by the less difficult characters of the colour, size, form of wing, 

 &c. — Dr. Chapman said that Mr. Merrifield had called attention at a 

 recent meeting of the Society to the difference in the wing markings 

 in the pupa and in the imago of Aporia cratmji, and exhibited some 

 specimens of considerable interest in relation to the question of corre- 

 spondence or otherwise of pupal and imaginal wings, viz. the imaginal 

 wings of Aporia cratagi removed from the pupa at a certain stage of 

 their development. The specimens showed that at this particular stage 

 the imaginal wings presented the markings of the pupal wing, a set of 

 markings which are in a way the reverse of those of the mature imago. 

 The specimens also showed that this stage was one when the imaginal 

 wing was still so immature that it was almost impossible to handle it 

 without producing injury and distortion. Though the markings were 

 there, they were not produced by pigmentation, at least not by formed 

 pigment. The dark markings of the pupal wings were represented by 

 areas that were more transparent than the rest of the wing. The fact, 

 he remarked, was curious enough whatever might be its minute 

 anatomy and precise meaning. The pigmentation of dark areas, Dr. 

 Chapman remarked, is usually the latest to develop, and here we have 

 apparently a less development in the dark area than on the pale ; and
