CUCULLIA GNAPHALII. 71 



on the head and thoracic segments they point for- 

 wards, and on all the others backwards. The ventral 

 surface is similar in colour to that of the sides, and 

 freckled in the same way with pale yellowish, in a 

 series of six longitudinal lines, rather thick and whitish 

 in the central ones ; that is, there is a broad central 

 one and one equally broad on each side of it, and two 

 other slender lines on each side of these, so that there 

 are seven in all. The larva has a rough mealy look, 

 which assimilates well to the rough stem of the plant. 

 As it matures, the dark stripe on the back becomes 

 paler, as though the green and pale yellow freckles 

 showed more plainly through it ; while the transverse 

 subdividing wrinkles towards the segmental divisions 

 become a little deeper and yellow when the larva 

 bends its body round sideways. 



By the 1st of September it had attained an inch 

 and a half in length, and the dark colouring on the 

 back had become a little paler. (W. B., September, 

 1871; N.B., I, 123.) 



CUCULLIA UMBRATICA. 



Plate XCYIII, fig. 5. 



To the kindness of the Rev. Hugh A. Stowell and 

 Mr. Greening I am greatly indebted for examples of 

 the larvae of this species, and for interesting details 

 of their early history. The first-named gentleman 

 captured a female at honeysuckle, which laid a large 

 number of eggs on the 11th of July, 1866, and in five 

 days they were hatched, and fed well on sow-thistles 

 (Sonchus). 



Unlike the sun- loving habits of others of the genus, 

 these larvae evinced a great aversion to light, and 

 always hid themselves by day, reposing under the 

 lower leaves of the sow-thistles, and at night ascending 

 and feasting on the upper leaves and flowers 



Those reared from eggs were full-fed by the 25th
