168 Journal New York Entomological Society. tVoi. xxiv, 



Mr. Angell exhibited a rare species of Strategus. 



Mr. Weiss showed a map giving the distribution, mostly in greenhouses, 

 of comparatively new insect pests and spoke also of the Cattleya midge, of 

 European earwigs becoming established at Newport, R. I., and of a hymen- 

 opterous leaf-miner. 



Meeting of April 4, 19 16. 



A regular meeting of the New York Entomological Society was held 

 April 4, 1916, at 8:15 P.M., in Heim's Restaurant, President Harry G. Barber 

 in the chair, with twenty-one members present. 



The librarian reported the binding of a set of the Journal in Holliston 

 Library Buckram No. 50. 



Mr. Howard J. Shannon, 73 Union Ave., Jamaica, L. I., was elected an 

 active member. 



Mr. Davis spoke of a number of species of Cicada, illustrating his re- 

 marks by maps showing the distribution and by boxes of specimens in which 

 were "pinned drawings made by Mr. Olsen, of the diagnostic structures. In 

 the course of his remarks he dwelt upon the necessity of specimens from 

 type locality for accurate comparison with the original descriptions and re- 

 counted the difficulties he had surmounted in obtaining such for some of the 

 early described species, which were thereby in some cases rescued from 

 undeserved synonymy. In respect of distribution, he said that Leconte's 

 districts, divided by meridional lines, and illustrated by the map in his 

 Coleoptera of Kansas and Eastern New Mexico, 1859, were, for Cicada, more 

 satisfactory than Merriam's zones, though the species with wishbone-shaped 

 uncas were perhaps somewhat southern in distribution except that they ex- 

 tended northward through the Mississippi Valley. 



Mr. Leng read a paper on " Omophron and its Distribution " in which 

 he attempted to show that while the preglacial dispersal of the genus was 

 from a northern centre towards the south, where Madagascar and Cape of 

 Good Hope in the old world, and Hispaniola and Mexico in the new world 

 have been reached, the postglacial dispersal has been in the contrary direc- 

 tion, viz. : from south to north, as evidenced by the spread of Gulf Strip 

 species like labiatuin and nitidnin northward, the one along the Atlantic 

 coastal plain, the other through the Mississippi Valley; and by the occurrence- 

 of numerous species now within the areas covered by ice during the glacial 

 period. His remarks were illustrated by specimens of the American species 

 and a few of those found in Mexico, Europe and Africa. 



Dr. Lutz and Mr. Davis, in discussing the subject, pointed out that the 

 idea of the north as the ancestral home of the larger groups was old and well 

 supported by geological evidence in mammals and in trees. 



Dr. Lehmann, upon invitation by the president, spoke of his interest in 

 certain groups of lepidoptera during the last seven years and his journeys, 

 completed and in prospect, devoted mainly to hunting Argynnis and Melitaa. 

 Utah, Colorado and California are planned for 1916, and he said he would 

 gladly give the lepidoptera caught outside his special desiderata to institutions 

 or individuals desiring them.
