DREPANULID^. 69 



dark brown freckles indicating the dorsal and subdorsal lines, 

 and a dark spot on each side of the twelfth segment ; the 

 under surface, the legs, and some portions of the sides are 

 pink, deeply tinged and freckled above with dark crimson- 

 brown, which fluctuates in height along the sides in two long 

 arches from the spiracular to the dorsal regions. When very 

 young, dark chocolate-brown, changing to russet-brown, and 

 as it grows the yellow colour of the back gradually appears 

 in dots, bars, and then patches, and the mature appearance 

 is quite gradually assumed. (Condensed from Buckler.) 



Mr. Buckler further points out that Hiibner in his great 

 work gives two figures of larvae under the name of sicula. 

 One has two tubercles and is correct, the other has eight and 

 is that of I), falcula. In copying from Hiibner the mistake 

 has, elsewhere, been made of selecting the wrong larva ! 



July to September or October on Tilia parvifolia ; when 

 very young feeding only on the upper surface, afterwards 

 eating long narrow passages into the middle of the leaf from 

 near the footstalk. 



Pupa rounded and tolerably even in thickness to near the 

 anal segment, which is prolonged into a spike bearing several 

 curved bristles ; rust-red, covered with a soft adhesive white 

 powder or bloom. In a cocoon of tough silk, containing 

 small apertures as though for admission of air, placed in a 

 drawn-together lime leaf. In this condition through the 

 winter. 



A rare species and excessively local in this country. 

 Discovered in 1837, when a single specimen was secured in 

 Leigh Woods near Bristol ; two more were found in the same 

 place in 1856, several more in 1861 and one in 1873. In 

 1874 and for many following years a more systematic search 

 was made by Mr. W. H. Grigg and others, a few being 

 taken every year, and some also reared from the egg and 

 from captured larvae. From 1887 to 1891 I find no record, 

 but specimens have since been met with, and there are good
