52 ENNYCHIA OOTOMACULaTA. 



persevered in his search again last year, and on the 

 18th of August found four of our still unknown larvae, 

 and again, on the 3rd of September, three more in a 

 younger stage than any previously detected ; my 

 friend kept for himself but two larvae, part of the 

 four first found ; yet, most fortunately, with one of 

 these he has been successful in solving our puzzle, 

 and on the second of the present month he had the 

 pleasure of breeding a fine female Ennychia octo- 

 maculata, and great indeed is the satisfaction this 

 success has given to both of us. 



Hitherto as a larva unknown in England, this 

 species is mentioned by Dr. E. Hofmann, in his 

 ' Kleinschmetterlingsraupen,' as living on and skele- 

 tonizing the under side of the leaf of Bellidiastrum 

 michelii ; but he gives no description of the larva 

 itself, nor does he say whether Hartmann, whom he 

 quotes, has described it. 



In this country the larva is found in a slight 

 whitish web on the under side of the lowermost 

 leaves of Solidago virgaurea, eating away large 

 portions from them ; when only the length of a 

 quarter of an inch it is of a whitish-green tint with 

 greener dorsal line, but after the next moult assumes 

 very much the appearance in all but size of the adult, 

 and again moults before attaining its full dimensions. 

 When full-grown the larva is from five-eighths to 

 nearly three-quarters of an inch in length, tapering at 

 both ends, the head somewhat broader near the mouth 

 than at the crown, the segments of the body well cut 

 at the divisions, particularly on the belly, where they 

 are very plump ; on the back there is a deep sub- 

 dividing wrinkle across the middle of each, segment, 

 and an ordinary wrinkle on each subdivision ; the 

 ventral legs are slender, the anal pair stretched out 

 behind in a line with the body, and the head similarly 

 extended in front. 



In colour the head is whity-brown, having a few 

 light brown freckles and black ocelli ; the back is
