HE YOUNG NATURALIST 

 EXCHANGE CLUB. 



A LL the parcels in connection with 

 \ this club have now been sent 

 it, and as the period of last season at 

 hch the suggestion was made, was 

 o Lite for many who would otherwise 

 ive joined it, we wish to make the 

 ;cessary announcements for next 

 ason now. We will first say a 

 Brd or two in reference to the insects 

 at have passed through our hands, 

 wisidering all things, the number of 

 ecimens that reached us was almost 

 ore than we could have anticipated, 

 d only one box contained such 

 mm on species as to be of little use. 

 ly one box also reached us with its 

 atents much damaged, and this en- 

 ely from careless packing. Among 

 ; insects sent, Messrs. Carter and 

 :th, of Bradford, supplied a series of 

 lia chi that differ considerably both 

 m the normal type of the species, 

 d from the northern form of it 

 low as Olivacea Stephens. The 

 t>e of Chi is described by Stain ton as 

 bug " whitish grey, the margins of 

 E> stigma and lines darker. " Newman 



says, ''White or whitish grey, with 

 numerous darker markings. The 

 hind wings of the male are pure white, 

 with a delicate marginal line, those of 

 the female are clouded with smoke 

 color, especially near the hind margin, 

 and on the wing rays, the head, 

 thorax, and body are pale grey, almost 

 white." These Bradford specimens 

 are much darker grey than any others 

 we have seen, the head, thorax, and 

 body are dark dingy grey, the hind 

 wings of the male are nearly as dark 

 as those of the female, but in some 

 specimens the fringe is a very pure 

 white. While they are thus darker in 

 shade than the type, they are equally 

 distinct from the variety Olivacea in 

 hue, which is a sort of olive green. 

 To compare them with other species 

 we might say, the type of Chi some- 

 what resembles H. serena, in color, 

 and the Bradford specimens resemble 

 //. dysodea. We shall be glad to hear 

 if this dingy form occurs elsewhere. 

 We also rececived from two members 

 specimens of the black form of 

 Betularice, called Doubledayaria, It 

 seems very curious that intermediate 

 forms between the type and this
