. ADSCITIDI. 387 



statices in Ino (i.e., Adscita) % Aurivillius appears to be the only 

 author who has followed this grouping. 



Bowell states (Entom. Record, etc., ix., p. 27) that in Adscita (Ino) 

 the scales are generally small, scantily distributed, and rarely bifid, 

 and those of the lower wings are less highly specialised than those of 

 the upper. The scales of A. chloros are the simplest, those of both upper 

 and lower wings being plain, strap-shaped. The scales of A. tenui- 

 cornis, A. pruni and A. chrysocephala form a middle group, with the 

 scales of the lower wings simple, those of the upper bifid. A. budensis 

 has peculiar scales, those of the lower wings are exceedingly small, 

 whilst those of the upper wings have their ends decorated with a 

 number of small points, viz., the ends of the columns separated by the 

 striae. This peculiarity is visible in the other species, though to a 

 much smaller extent. The scales of A. ampelophaga are the most 

 highly developed of those examined, those of the lower wings being 

 bifid, those of the upper trifid, occasionally even quadrifid. We have 

 previously (Brit. Noctuae, etc., ii., p. xvi.) discussed the peculiar 

 phenomenon observed when species of this genus are enclosed in a 

 clamp box, the green scales becoming changed into a bronzy or red- 

 brown colour. 



So far as our British species are concerned, the eggs are so similar 

 that Chapman could distinguish no difference between them, except 

 in size. The newly-hatched larvaa, too, are practically identical. 

 The pupas, also, are very similar, but these similarities, and such 

 differences, as exist, will be best obtained from the detailed accounts of 

 the larva and pupa of each species that follow. 



It is well-known that cross-pairing occasionally occurs among the 

 various species of the genus Anthrocera, but Oberthiir states (Lep. des 

 Pyrenees, p. 31) : " Nous avons meme trouve - une Zygaena filipendidae 

 solidement jointe a une Procris ! Nous aurions eu de la peine a croire 

 une pareille enormity, si nous ne l'avions nous-memes observed et si 

 nous n'avions tenu par les antennes la Zygaena entrainant la Procris 

 soudee avec elle." 



Gynandromorphous examples of this tribe have been recorded by 

 Slater in A. geryon (right $ , left ? ), from Britain ; in A. ampelophaga 

 by Schultz [(1) right <? , left $ , (2) left $ , right $ ] , from Hungary ; 

 in A. pruni, by Schultz (right $ , left $ ), from Pesth. At least 

 seven gynandromorphous examples of the two latter species have been 

 noticed.
