306 THE CANADIAN ENTOMOLOGtSt. 



Our plunder ihis season was all attacked by pests, necessitating a 

 severe cyaniding. Much of the brightness in this butterfly was lost, the 

 colour now resembling the brown leaf-green of oak trees late in August. 



Scales on the under side are very heavy, there being no suggestion 

 of a band ; the extra mesial spots on primaries are almost wanting, and the 

 general ground colour is a deep chrome. A thick daub of this paint 

 from a good box duplicates it exactly. 



On the basal half of the disk in secondaries there is a suggestion of 

 green, and extended from that portion of the primaries covered by the 

 lower wings when at rest, which is of the pallid hue mentioned above, 

 nearly covering the outer half of discal cell, thence interspacing the 

 media and cubitus to the mesial spots, from which it bends sharply to 

 the outer angle, reaching the margin at lower branch of cubitus, there is 

 an overvvash of black. This is deepest at its inner border and curiously 

 shaded as it blends with the chrome. The whole lower surfaces, with 

 their bright tips and bold opaque colours, are very handsome. 



Number two is a female, pallid above, like a white female, except 

 that the black margin reaches from the discal vein, on the costal side 

 follows the radius, joining margin at its first branch and posteriorly 

 defines the media as far as the border. The outer portion of disk and 

 the costal margin on primaries are more or less splashed with dark scales, 

 while on secondaries the marginal band is only indicated by a dusting on 

 edges of the veins. 



Underneath the spots are much exaggerated. On the primaries 

 they appear as large triangular black stains, with apices reaching farther 

 and further towards the base until between radius and media they touch 

 the discal spot. On the lower wings this stain is ferruginous, shading to 

 green, and practically covers the disk. The unusual size of these spots 

 outlines a white marginal band, the distinctive feature of the specimen in 

 question, 



THE ACADEMY OF SCIENCE, ST. LOUIS, MO. 

 At the meeting of November 2, Mr. Colton Russell spoke of " What 

 an Entomologist Can Fmd of Interest about St. Louis," illustrating his 

 remarks by numerous pinned specimens of insects, giving particular 

 attention to the butterflies, and speaking at some length of the phenomena 

 of periodicity, migration, polymorphism, etc., as illustrated by these 

 insects, his paper embodying the result of a large amount of field work 

 performed during the last ten years. Resolutions opposing the passage 

 of the Antivivisection Bill now before the United States Senate were 

 adopted. Three persons were elected to active membership,
