 with a specimen ( 9 ) of Caenocam bovistae Hoffni. ; also specimens of Cn/pto- 

 lihayus l(pevendali Ganglb., which he had found in large numbers in a nest of 

 Vespa yermayiica in a tree in Richmond Park en November 20lh, 1917, a 

 species of which only two specimens had been taken in Britain before. Mr. E. 

 A. Butler ova of the following species of llemiptera: two species of Penta- 

 tomidae, Fiezodorus lituratus Fabr.. and Pentatoma rujipes L. ; Choroscma 

 schillinyi Schml, a Coreid bug; two species of Ben/tus -, three Reduviids, 

 Ccranus suhapterus L., Nahis major Costa, and N. luyosus L. ; a Capsid bug, 

 Miris laeriuatus: and three Avater bugs, Naucoris cimicoides L., Notonecta, 

 glauca L., and Nepa cinerea L. Mr. Kaye, from Mr. Joicey's collection, series 

 of the two Cutoyramma species pastazza and eicelswr, with races and forms 

 of each, pointing out that the two groups of insects were at once separable by 

 the differences in the tips to the antennae; also anew species of Dynamine 

 {B. ayatha) from Bolivia. Lord [lothschild, a series of Pseudacraeas, in

 I'rof. Poulton, a new form of Pseudacraea poyyei Dew., mimicking the 

 duripjms Klug form of Danaida chrysippus L., in ex-German East Africa; 

 also examples of 66 males and 80 females of Musca autuvmalis, captured 

 December 14th, 1917, in the cistern-loft of St. Helen's Cottage, St. Helens, Isle 

 of Wight. The loft had not been examined in the winter since January 4th, 

 1915, when far greater numbers of the iiies were present. Prof. Poulton said 

 that he owed to Mr. J. J. Joicey the opportunity of exhibiting the type of the 

 West African E. urtmia, from the collection of the late Mr. H, Grose-Smith, 

 and of comparing it with the series oi posthumus in the British Museum. He 

 read extracts on the habits of Ethiopian species of Saranyesa and other Hespe- 

 ridae from a letter written by the Rev. K. St. Aubyn Rogers, from Kongw\i, in 

 ex-German East Africa. Prof. Poulton said that he witched to draw attention 

 to an unfortunate misconception in the recently is.-?ued part of Mr. Charles 

 Oberthiir'a beautiful work, ** Etudes de Lepidopterologie comparee," Ease, xiv, 

 1917, since the Sesias are mimics and not models of the Hymenoptera. He 

 also said that he had just received a letter from Mr. C. O. Farquharson, dated 

 December 13th, 1917, from Ibadan, describing Harpayotnyia and other Diptera 

 being fed by Creniaduy aster ants in S. Nigeria.
