was always partly a double-brooded species ; T. biundularia appeared 

 early in May until the first week in June, and was only single- 

 brooded ; in every case the insect remained true to the parent type ; 

 and although the markings were somewhat alike in both species, yet 

 there were characteristic differences as shown in the series exhibited ; 

 this also applied to the larval stages. Mr. Barrett and Mr. Tutt made 

 some observations on this exhibit, the latter gentleman agreeing with 

 Mr. Tugwell, but the former was of opinion that crepuscularia and bi- 

 undularia were not distinct. Mr. Turner showed a very light form of 

 Nyssia hispidaria, Fb., from Eichmond. Mr. Carpenter also exhibited 

 varieties of the same species. Mr. Fenn, a long series of Larentia 

 multistrigaria, Haw. Messrs. Skinner, B. W. Adkin, and Mr. West 

 exhibited Coleoptera, the latter gentleman a very interesting collection 

 from the Colombian Republic. Messrs. E. Step, W. Manger, C. G. 

 Barrett, Tugwell, Billups and others, also exhibited. — H. W. Barker,

 March l 10th. — J. A. Clark, F.E.S., in the chair. Mr. Quail exhibited 

 a specimen of D. galii, Schiff., captured at Stoke Newington in July, 

 1888. Mr. Simes, a remarkably small E. cardamines, L., taken in 

 Epping Forest, May, 1889. Mr. J. A. Clark, two varieties of T. 

 gothicina, H.-S., the wings of one specimen, although having the 

 markings of this species, strongly resemble T. incerta, Hum., in shape. 

 Mr. Whittle, a series of Catoptric/, Juliana, Curt., and Paclisca oppress- 

 ana, Tr. Mr. Lewcock read a paper on behalf of Mr. Robert Gillo, of 

 Bath, on the occurrence of aquatic Coleoptera at Burnham, Somerset, 

 in September, 1889. It appeared therefrom that Mr. Gillo, by per- 

 sistently working the district, day after day, had obtained forty-two 

 species ; included in this number were Pelobius hermanni, F. ; Hali- 

 plus mucronatus, Steph. ; HydropJiilus picens, L. ; Dytiscus circumflexm, 

 F., and D. punctulatus, F. ; in addition to these, he also found several 

 species of Elmis, Latr., and Panius, Fabr. Mr. Lewcock also read a 

 paper on behalf of Mr. P. W. Jarvis, of Cape Town, on the " Cole- 

 opterous Fauna of South Africa." The number of species taken 

 south of the Zambezi amount to upwards of 8000 ; Madagascar, 

 having a distinct fauna of its own, is not included in the South- 

 African list. The district appears to be very rich in Cicindelidge, 

 having about 50 species. The genera Carabus and Pterostichus are not 

 represented, but in place of them are twelve species of Anthia, which 

 are larger and far more powerful than our largest Carabus beetle, and 

 twelve of the genus Polyhermia, which also are highly voracious 

 insects ; three species of the latter are so deeply pitted as to give the 

 elytra the appearance of being perforated. A species of Brachinus 

 found near Cape Town is three quarters of an inch in length, and the 

 explosion emitted by it is in proportion to its size. Aquatic species 

 are fairly represented ; but Staphylinidae are not quite so numerous as 

 in Britain, although M. Fauvel has recently described fifty new 

 species. Necrophagous beetles are not numerous, but several species 

 of Histeridaa exceed three-quarters of an inch in length. Upwards 

 of five hundred Larnellicornias are found. Some species of Helioropris
