and the Peruvian Andes. Prof. T. Hudson Beare, a specimen of Tracht/phlmus scabri- 

 cuius with the two deciduous mandibles still in place, taken at St. Margaret's Bay. 

 Lieut. -Colonel Manders, the ? of Papilio phorbanta from Bourbon, an aberrant 

 member of the nireus group of Papilios, and compared it with the other members 

 of the same group from the African mainland, Madagascar and Mauritius kindly 

 lent for the purpose by Profess >r Poulton. The case is dealt with more fully and 

 the insects figured in his paper on " The butterflies of Mauritius and Bourbon," in the 

 Trans. Ent. Soc , 1907, pp. 449—451. Dr. K. Jordan, on behalf of the Hon. Walter 

 Rothschild, some interesting Papilionids: (a) Troides alexandrse, Rothsch., remark- 

 able for the beauty of the $ and the gigantic size of the $? , a new discovery by A. S. 

 Meek, who found this fine insect in the north-eastern portion of British New Guinea 

 at some distance inland from the coast ; (b) a gynandromorphic specimen of Troides 

 haliphron, Boisd., the only one known of this genus, obtained by Dr. L. Martin in 

 South Celebes, the left side being <j? and the right side $ . Mr. R. Adkin, specimens 

 of Tortrix pronubana, Hb., reared in June and July from larva? collected in May, 

 also others reared in autumn from ova deposited by moths of the June emergence. 

 His observations had led him to conclude that, as had been shown to be the case in 

 Guernsey, the species would be found to be practically continuously brooded 

 throughout the summer months, the chief emergences taking place in June and 

 October, but with stragglers appearing probably in every month from April to 

 November. Mr. L. W. Newman, long series of Melitxa aurinia, and Nolodonta 

 chaonia, from many localities in the United Kingdom, to illustrate the wide super- 

 ficial variation of the respective species. Dr. F. A. Dixey exhibited specimens of 

 Nyehitona medusa, Cram., and Pseudopontia paradoxa, Feld., observing that a 

 former suggestion of his as to a mimetic relation between them had been confirmed 

 by a letter lately received from Mr. S. A. Neave, at present in the Congo State, who 

 wrote that the two forms " inhabit exactly the same localities and are barely dis- 

 tinguishable from each other on the wing." Mr. Rowland F. Turner communicated 

 a paper " On Two Diplopterous Hymenoptera from Queensland," and " Notes 

 on Thynnidw., with remarks on some aberrant genera of the Scoliidee." Mr. 

 Guy A. K. Marshall read a paper " On Diaposematism, with reference to some 

 Limitations of the Mullerian Hypothesis of Mimicry." In this he pointed out the 

 difficulty of accepting the idea of a mutual simultaneous mimicry between two 

 unpalatable species, such as is postulated by the hypothesis of Diaposematism. 



The General Meeting which followed was adjourned to March 4th. —

A FORTNIGHT'S WINTER COLLECTING IN VENEZUELA. 

 BY G. B. BONGSTAFF, M.A., M.U., F.U.C.P., F.E.S. 



On December 20tli, 1900, the K.M.S. " Tagus," bound to Jamaica, 

 touched at La Guaira, a place that Charles Kingsley has immortalized 

 in his great romance. Owing to the formalities of the Venezuelan 

 officials we could not land till the afternoon was far advanced. The
