THE PUPA OF CHRYSOPHANUS DISPAR. 15 



sional Lycaena avion. Melitaea athalia, M. dictynna and Pararge maera 

 were the only other species seen. I soon got tired of this tameness, 

 and, having devoted half-an-hour to getting together a series of several 

 interesting Pyralids, I decided to descend more towards the valley. I 

 was almost immediately rewarded by finding Polyommatus astrarche, 

 and further down P. bellan/us, in abundance. While engaged in sorting 

 out good specimens a somewhat lighter coloured male caught my notice, 

 which proved to be the first P. hylas, and almost immediately after- 

 wards the first Coenonympha satyrion fell to my net. As this spot 

 seemed to be fairly productive I decided to remain, and in the course 

 of an hour had increased my catch by Erebia oeme and Brenthis 

 amathusia. I was naturally very delighted at finding this last species, 

 as it was new to me. Burnets were busily employed buzzing about 

 from flower to flower, and a good many were captured, but only 

 Anthrocera achilleae, A. filipendnlae and A. purpuralis seemed to be 

 present. On the way home, at the foot of the hill, a swampy hollow 

 proved very productive ; the commoner blues were in hundreds, 

 accompanied by Chrysophanns hippothoe, Arf/ynnis niohe, A. aglaia, 

 Brenthis amathusia, Enodia hyperanthus, and, above all, a fine large 

 form of Coenonympha tiphon. In the afternoon a visit was paid to 

 Moorbad, and, on the moor, C. tiphon and Brenthis pales were found 

 in abundance, the latter, unfortunately, no longer in good condition. 

 (To be concluded.) 



The Pupa of Chrysophanus dispar (idth plate). 



By Dr. T. A. CHAPMAN. 

 In the photograph (pi. i., fig. 1) the spiracle of the left side of the 

 6th abdominal segment is shown, with its surrounding territory ( x 100). 

 We have here a very definite difference between the sculpture and 

 hairs, otherwise so much alike of Chrysophanus phlaeas and C. dispar. 

 In C. phlaeas there appear to be no hairs except the trumpet-hairs, 

 whilst in C. dispar we have long hairs (O'OSmm. to O'lTmm.) of more 

 ordinary type. These occur, however, only in the circumspiracular 

 region, including the prothorax. Each hair is a little swollen in its 

 last third, and from the surface of this portion arise a number of fine 

 spiculae, generally standing out at right-angles to the axis of the hair, 

 producing a very different appearance from the spiculated hair so often 

 met with. Amongst these hairs in the photograph is one, viz., that 

 pointing and with its end close to the side of the spiracle, which, instead 

 of terminating in a sharp point, has an oblique flat end, armed with 

 spiculfe, clearly a hair that was not quite sure it ought not to have 

 been a trumpet-hair. Several trumpet-hairs may also be seen in the 

 photograph. The great mass of the circles unprovided with hairs are 

 no doubt lenticles — some may be hair-bases where the hairs have been 

 lost. Unfortunately, in the preparation, a majority of them have 

 succeeded in retaining an air bubble, which makes them look black in 

 the photograph. Nearly all those, however, that are not so obscured, 

 possess a membrane or diaphragm of minutely dotted structure, like 

 that usually met with in lenticles. The spiracle is of elaborate 

 structure. It may be described as an oval tube nearly as long as it is 

 wide, with the opening it presents diminished to a central slit by 

 membranous outgrowths on the sides, nearly meeting in the middle.
