144 Mr. Roland Trimen's Observations on the 



This temporary functional activity of the cephalic pro- 

 cesses for a special object, aided by the freedom for the 

 time of the incipient haustellum (or antennie ?) case, is 

 quite unprecedented in my experience, nor can I recall 

 any record of similar action attending the assumption of 

 the pupal form among the Lepidoptera. And it is cer- 

 tainly a most curious and interesting fact that the very 

 organs actively employed in ensuring the due accomplish- 

 ment of the chrysalis state are specially those which, when 

 the change is complete, assume a position and appearance 

 essential to the protection of the insect, — the haustellum 

 representing the midrib of the leaf (on the upper side) and 

 the processes the apex. 



With reference to the various forms of Blerope reared 

 l)v Mr. Weale fi-om the larvae of the past season taken on 

 his farm, I very much regret to state that my intention of 

 forwarding the Avhole series to the Society, in illustration 

 of that gentleman's memoir, cannot be carried into effect. 

 IV [r. Weale kindly despatched the specimens in a stout 

 corked box, bvit they sustained such grievous injuries on 

 their 700 miles journey by ]30st, that they arrived in a 

 state which quite precludes their being used for purposes 

 of illustration, as far as the females are concerned, — the 

 males being mostly but little damaged. By dint of some 

 care and trouble, however, I have been able to patch up 

 the females to a sufficient extent for their proper determi- 

 nation, and can testify to their due definition in the list 

 which Mr. Weale has given. The "peculiar Hippocoon 

 form " (No. 3), is one of several variations with which 

 I am acquainted, linking that form of the $ to the form 

 Cenea. In the forewings both the sub-apical white bar 

 and the inner-marginal Avhite patch are considerably 

 smaller and narrower than in the ordinary southern 

 Hippocoon, the latter marking being interiorly clouded 

 Avith blackish. It most nearly resembles the variation 

 figured in the second plate accompanying my paper in the 

 Linnean Society's Transactions (vol. xxvi., tab. 43, f. 2), 

 and like that example wants the apical spot of the fore- 

 wings ; but (as far as I can make out in its very damaged 

 state) it has more resemblance to Hippocoon in the wider 

 Avhite space of the hindwings. The Trophonius (No. 7) 

 differs both from that figured by Westwood {Arc. Ent., i., 

 pL 39, ff. 1,2), and from the example figured to illustrate 

 my paper just referred to {loc. cit., tab. 43, f. 5), in the 

 longer and more obliquely-placed sub-apical bar of the
