LOPHOPTERYX CUCULLINA. 



Plate XXXV, fig. 4. 



Mr. Buckler figured this species from maple August 

 16th, 1860, August 20th, 1866 (breeding the moth 

 July 7th, 1867), July 10th, 1870. 



In 1858, June 14th, I bred a moth from a pupa I 

 had dug during the previous winter without recog- 

 nising it ; in 1861 I bred moths June 15th to 17th. 

 In 1866 I had eggs, the larvae from which hatched 

 July 17th, but I have no further record of them. In 

 1886 Mr. W. H. B. Fletcher sent me eggs July 17th, 

 which unfortunately proved unfertile; August 28th 

 Mr. J. Anderson sent me larva? of various sizes, but 

 all in the last skin ; and September 10th Mr. Fletcher 

 sent me some full-grown larvse on sycamore. 



The egg is button-shaped, fuller than the eggs of 

 some of the " Prominents," being 0*85 mm. wide and 

 0'75 mm. high, the glossy shell without any ornamen- 

 tation, the colour entirely opalescent greenish. The 

 full-grown larva is about 30 mm. long, cylindrical, 

 tapering much from segment 6 forwards, 13 sloping 

 rapidly, the shining head extending beyond 2 in every 

 direction, the face flat with rounded sides, widening 

 below, the segments distinctly marked, the skin 

 wrinkled; on 6 — 11 a series of slightly raised dorsal 

 humps, diminishing backwards, these humps slightly 

 divided longitudinally and transversely into four small 

 swellings, on 12 a more prominent and sharper hump 

 ending in twin points, which are set with six hairs, 

 the places of the usual dots marked by stiff hairs, the 

 anal prolegs small, held up when the larva is feeding ; 

 the colour varies, one variety was greenish-white on 

 the back, on 2 — 5 a broad dorsal green stripe edged 

 with white widening backwards, and then coming to 

 a point on 6, a green dash through the humps on 7 — 

 10, thence a green dorsal line, interrupted on 12 by 

 the hump, a faint green subdorsal line, the sides glau-
