Stenoptilia grandis. 310 



flowering stems, the pupa3 were quite unassociated with 

 these and were usually on the mid-rib about the middle 

 of the upjoer side of a leaf. 



Except in size these pupai differ very little from the 

 others of the group. 



I append a note on the pupa. 



The pupae M'ere found on the centre of leaves of Gentiana lutca, 

 altogether 14 were found, full, empty — good and bad — always near 

 the centre of leaf, usually on the mid-rib, on upjier surface and as 

 usual head downwards. They are 12 to 13 mm. long. Thoracic 

 portions rather swollen, 2-3 mm. wide, about 2 mm. from nmta- 

 thorax backwards, but with a falling in of sides (dorsally) of forward 

 abdominal segments and meta- and portion of meso-thorax that gives 

 an appearance to abdomen of being spindle-sbaped, it tapers off very 

 regularly in last four segments to a rather sharp point. The falling 

 in of sides is in accentuation of the prominence of dorsal ridges in a 

 hump on posterior margin of dorsum of 2nd thoracic. 



Seen laterally, the pupa is straight ventrally — dorsally arches back 

 from nose-horn to the hump on meso-thorax, then fuller to 1st abdo- 

 minal whence it is fairly straight till last four segments. The dorsal 

 ridges arch outwards on middle of mesothorax and form an elliptic 

 raised surface, thence (i. e. from hump) they separate, especially 

 on 1st abdominal and end at II of 3rd abdominal. There are no 

 hairs, but there are points marking I and II on abdominal. The 

 colour is green of most of abdomen tending to ochreous at last 

 segments and also on meta-thorax and 1st abdominal ; forwards it 

 is overlaid by whitish, so that on front view the pupa is white. 

 The appendage- cases are dark, getting nearly black in some pupae ; 

 2nd and 3rd legs form a free style beyond end of wings, down 

 to middle of 6th abdominal. The venation of wings is marked, 

 and the whole surface is finely ridged transversely. The pupa is 

 like a large, robust zophodackjlus pupa less richly coloured. 



I have also a solitary specimen from Pajares (Asturias, 

 Spain) that is paler than the French ones, and in facies 

 suggestive of ayprodddylvs, but agrees in essential mark- 

 ings and in size with grandis; being a solitary specimen, 

 I have not examined the appendages, but believe there is 

 no doubt the specimen is specifically identical with those 

 from Larche. 



Hofmann notes under coprodactyhis : " Male specimens 

 from the Alps are often very large, remarkably pale and 

 little marked ; three very dark large specimens in Reutti's
