144 THE ENTOMOLOGIST. 



beyond the discoidal black spot, the inner edge curving outwards 

 and not extending beyond the first median nervule, thus leaving 

 the hinder angle white; this disposition of marking he found 

 perfectly constant in those captured. In the Continental speci- 

 mens the orange spot extended considerably beyond the discoidal 

 spot and was continued to the inner edge of the wing, causing 

 the hinder angle to be orange. The distinction pointed out was 

 very small, but if it were constant our E. cardamines was an 

 insular variety, easily separable from Continental specimens. 

 Mr. Tutt read a paper on " The Morphology and Physiology of 

 an Insect," which was followed by a discussion, 



April I2th, 1888. — The President in the chair. Mr. Slater ex- 

 hibited a large Bomhyx from Zulu Land, which he said approached 

 nearest to Bomhyx ouble taken by M. Guerin in South Abyssinia, 

 and might be a local variety of that insect ; if not, it was a new 

 species. Mr. J. Lea, varieties of Tceniocampa munda, light 

 specimens without the twin black spots.* Mr. Henderson, forms 

 of Satyrus semele, Ciicidlia verbasci, from various localities, with 

 a view of illustrating the local variation of the species. Mr. 

 Adkin, bred specimens of Pygara anachoreta, from Saltwood. 

 Mr. Carrington thought that the species was no doubt intro- 

 duced into this country with the balsam poplar, and gave many 

 instances which he had met with of various species being 

 introduced by the importation of plants. Mr. Tugwell, grey and 

 black forms of both sexes of Nyssia liisindar'ia, which he stated 

 were all bred from one batch of eggs ; there was, however, very 

 little variation in the larvse. Mr. J. Jenner Weir, specimens of 

 Pieris hrassicce from St. Petersburg, lat. 60°; Lewes and Black- 

 heath, lat. 50° and 52°; Hyeres, lat. 43°; and remarked that the 

 species did not differ from places so remote either in marking or 

 in size. Mr. T. R. Billups, a living specimen of the genus Asjndi- 

 morpha, which he said was an apparently new species, and was 

 brought from Upper Burmah amongst the roots of an orchid 

 {Dendrobium hrymerianum). The Secretary read a note from Mr. 

 T. D. A. Cockerell with reference to an exhibit of a new rose 

 gall from Custer Co., Colorado, which had been pronounced by 

 Mr. L. O. Howard, of the U. S. Department of Agriculture, to 

 be the product of an undescribed species, Rhodites tuberculator, 

 specimens of which were contained in the collections of the 

 Department. — H. W. Barker, Hon. Sec.
