 other districts near Liverpool. Tsetse-tlies : A large collection con- 

 taining all the known species of Glossina was on view. The most 

 important species are Glossina palpalis, chiefly responsible for the 

 transmission of sleeping-sickness, and G. morsitans, wliich spreads 

 trypanosomiasis among horses and cattle. Acarids affecting Hour : 

 Specimens of the acarid Aleurohius farinosce and samples of Hour in

The Entomological Section of the Northumberland and 

 Durham Natural History Society. — Ajyril 9th. — Dr. F. C. Garret, 

 President, in the Chair. — Mr. Bagnall sliowed and described slides of 

 Thysanoptera and other obscure groups. — The Messrs. Kosie beauti- 

 ful sets of local Diptera, Micro-lepidoptera and preserved larvae. — Mr. 

 J. Baxter, a fine Euvanessa antiopa with its marginal yellow band 

 heavily speckled with black, caught by himself at the Black Hall 

 Rocks, also a series of Vanessa io which after an absence of forty 

 years has occurred every year since 1911 in the Team Valley. — Major 

 Gardner exhibited recently captured local forms of Phigalia pcdaria 

 and Hybernia Icucophaaria showing its full range of variation.— Dr. 

 J. W. H. Harrison brought for exhibition and discussion fine series 

 of various hybrids, including many new ones ; likewise a black Selema 

 bilunaria, a brown black example of the same, a gynandromorphous 

 Oporabia aiUumnata (right side male, left female), and some remark- 

 able aberrations of 0. dilutata, a pure black form, the ordinary grey 

 form with all markings inward from the subterminal line obsolete, a 

 black form with a silvery central band which abounds in a 

 wood near Lanesley, and the variety latifasciata. He also 

 showed a fine Pieris napi var. flavcscens from Forres and some 

 Tcphrosia bistortata of the single-brooded local form which, reared 

 at 80° C., approximated closely to the other species, T. crcpuscularia. 

 Various members joined in the discussion and gave their experiences 

 of the past season.
