line with spiracle and a good way below it, a little ventral to the 

 front of the two marginal hairs, and another behind and only a little 

 below spiracle. The 6th and 7th abdominals are the same, as also 

 the 8th, though the spiracle is cicatricial. The hairs are about 

 0-25mm. long, slender, smooth, and pointed. Further details would 

 unduly extend this already lengthy description, but it ought, perhaps, 

 to be noted that there is a (femora ?) piece between the maxilla and 

 first leg, that there are two (antenna-basal) hairs on either side of the 

 vertex and a pair at the base of the labrum.

Everes alcetas (coretas) as a distinct species from Everes argiades.

{Concluded from p. 237.) 



It becomes, therefore, interesting to have Reverdin's remarks on 



the two insects, as occurring in Switzerland ; alcetas only seems to 



occur in the Valais. He also notes the difference in the shape and 



Form. No. Sex. Right wing. Left wing. No. Sex. Right wing. Left wing.

*This figure is worth a few remarks outside the subject of the paper. The 

 original photograph is a very beautiful and perfect one by Mr. Main of the living 

 moth in resting attitude, natural size. It was hopeless to produce this with any 

 useful effect by the process employed in this plate (or any other?). The brown 

 markings are individual scales, or at most groups of very few. It occurred to me 

 that the photograph could be enlarged so as to overcome the difficulty, and in 

 this case four diameters was decided on with the result shown. It is haixlly 

 probable that this simple device has not been resorted to in figurmg insects. 

 It is clear, however, that it affords a method of accurately showing details 

 hitherto wanting, and should prove useful in plates of lepidoptera, especially of 

 the smaller species. — T.A.C.
