females of cyuthia, and vice-versa., in boxes, but in no case did pairing take 

 l)lace, the males and females crawling over each other as if they were all of 

 one sex. The one window of this room was kept closed, which must have 

 been the cause of non-pairing, as there was no current of air, conse- 

 quently the males, which seemingly have to depend a good deal on the 

 draft of air, were not able to locate the female. One crippled female of 

 Telea polyphemus was taken outside towards evening, in June, and placed 

 on a shrub. It was found copulating the next morning with a fine male 

 of the same species, the female commencing to deposit its eggs during the 

 following night. This shows that for successful copulating insects need 

 the fresh air. 



Of Hyperchiria io hatching in February and March, some (male and 

 female) were also put together in a large box covered with gauze, but with 

 the same result ; none were found to pair, although left together for a 

 week, during which time some males and females never left the spot where 

 they settled the first day. No female of these deposited any eggs during 

 that time, whilst of S. cynthia and C. promethea sterile eggs deposited in 

 June and July could be counted by the thousand. 



Description of an odd variation of Telca polyphemus, male, hatched 

 last summer : Wings almost transparent. Primaries almost without any 

 shading, the usual band near outer margin removed nearer towards ocelli, 

 which itself is narrower as in typical form, elongate, nearly perpendicular 

 with sharply pointed ends above and below, surrounded with yellow, then 

 black, having on margin towards base a red band slightly intermixed with 

 pale blue ; above ocelli a dirty red dash extending to costa ; the lower 

 part of the irregular band near base wanting, leaving only the upper part, 

 which is also more perpendicular, and crescent shaped. Near base almost 

 entirely bare. 



Secondaries unicolored, the usual dark band removed close to ocelli, 

 bordered towards outer margin with a broad bare band. Ocelli the 

 reverse in shape from those on primaries ; outer line straight and inner 

 line convex ; bordered towards outer margin with a black band extending 

 on the outer side around ocelli, terminating in a narrow crescent-shaped 

 black line above, encircling a narrow light blue band which is itself shaded 

 by a darker blue, crowned by a wide white band bordered with red. A 

 second pale but dark wide band runs almost parallel with first, only broken 

 by ocelli, which is altogether but a little over half as large as on typical
