continued from the head to the extremity of the anal flap ; the 

 series of spiracles is just above the lateral stripe, and of the 

 same pale colour. Note. — This larva is so like that of 

 Lobophora lobulata, described at page 8700 of the ' Zoolo- 

 gist,' that it is difficult to express the difference in words, 

 but through the unceasing kindness of Mr. Doubleday I 

 have been enabled to place side by side specimens of both 

 species reared from the egg, and a careful comparison shows 

 that the larva of L. polycommata is the more robust of the 

 two. It undergoes pupation just below the surface of the 

 earth, and remains in the pupa state throughout the winter.

Description ofilie Larva of Hyhernia leiicopJicBaria. — The 

 eggs are laid by the apterous female on the trunks and 

 branches of Quercus Robur (oak), in March : the young larvai 

 are hatched towards the end of April or beginning of May, 

 and as soon as the leaves expand the young larvae fasten 

 them loosely together, forming a little domicile for conceal- 

 ment from the prying eyes of birds, which at this season are 

 constantly on the look-out for larvae with which to feed their 

 young. The larva? are full-grown in June, and then rest in 

 various positions, but I have rarely observed them in that 

 rigid stick-like attitude so common with those Geometric 

 larvae which feed constantly exposed : when disturbed they 

 emerge from their domicile, and hang sus])ended by a thread. 

 Head narrower than the body, porrected, not notched, but 

 exhibiting in a very marked manner the triangular space on 

 the crown ; body obese, transversely wrinkled and verrucose, 

 having also a manifest lateral skinfold. Colour infinitely 

 varied, indeed so much so that it seems desirable to describe 

 five of the more common types of ornamentation. No. 1. 

 Head and 2nd segment apple-green, concolorous : body yel- 

 low-green, with lour paler dorsal stripes, which extend from 

 the 3rd to the 12th segment, both inclusive ; of these four 

 the interior pair are the narrowest ; equidistant from each ex- 

 terior stripe and the lateral skinlold is another stripe about 

 equal in width to, but less distinct than, the two medio- 

 dorsal stripes ; the ventral surface is yellow-green ; the 

 clasiicrs apple-green ; the legs pale sickly green. No. 2 has 

 the head pale green, the cheeks delicately reticulated with 

 black ; the body also pale green, the 2nd segment having
