subdorsal and lateral blotches, spots and lines, are sometimes almost 

 or entirely wanting, leaving the larva a uniform pale yellowish green. 

 This larva very strongly resembles that of E. satyrata in form and 

 appearance, bul is less robust. It tapers towards the head, and has a 

 slightly wrinkled appearance. When full fed and ready to spin up it 

 turns pink. Pupa enclosed in a slight earthen cocoon. Thorax yellowish 

 green, wing-cases dark green, furrowed and wrinkled. Abdomen 

 tapering, rough, dull red. A slight ventral protuberance. 



1 have for the last four or five years been in the habit of taking this 

 larva and breeding the perfect insect, which from the first I recognised 

 to be quite distinct from all our previously known British species. 

 After much delay I have at last, through the kindness of Mr. Double- 

 day and M. Herrich-Schaeffer, succeeded in getting it named. The 

 larva appears to be totally unknown on the Continent. It feeds in 

 September, in damp woods, on the flowers and seeds of Angelica syl- 

 vestris, and occasionally upon late flowers of Heracleum sphondylium. 

 I have taken it in Suffolk, Kent and Derbyshire. The perfect insect 

 appears in May and June. The larva is uncertain in its appearance. 

 In 1859 it was by no means uncommon ; in 1860 it seemed to have 

 entirely disappeared. It is frightfully infested by ichneumons, and 

 not above one in ten or twenty escapes. 



Description of the Larva of Eupithecia trisignala, H.-S. — Rather 

 short and stout, tapering but slightly towards the head. Ground colour 

 pale green. Central dorsal and subdorsal lines dark green, latter 

 broader than the former. Spiracular line waved, whitish. Segmental 

 divisions yellowish. Head black when at rest, curved considerably 

 inwards. Anal tip of central dorsal line purplish. "Back wrinkled, 

 sprinkled with a few very short bristly hairs. Belly green, with a 

 central yellowish line. Pupa enclosed in an earthen cocoon. Thorax

 tapering, reddish yellow ; tip and divisions blood-red. 



Two years ago Mr. Greene and I were searching for larvae of E. tri- 

 punctata in Derbyshire, when I stumbled upon two larvae which I at 

 once saw were those of no British Eupithecia I had ever yet seen, 

 their black heads giving them a most distinct appearance. Mr, Greene 

 was afterwards fortunate enough to meet with more, and from them 

 we bred what turned out to be E. trisignata, H.-S. The larva feeds 

 in September on flowers and seeds of Angelica sylvestris, in company 

 with, and in similar situations to, E. tripunclata. Mr. Greene and I 

 have only met with it in Derbyshire. In Switzerland it feeds on flowers
