within which it constructs a very delicate cocoon ; Ratzebur^ and Har- 

 rach raised it from Lasiocampa pini, Brischke (Schr. Oes. Danz. 1882, 

 p. 135) both from that species and Euplexia huipara in Prussia; and the 

 var. giganleum has been reared from Bomhyx trifolii by both Ratzeburg 

 and Gravenhorst. With us it is by no means a common insect and I 

 have never seen it aHve. Gravenhorst thoui,dit Eleazar Albin's pL vii, 

 representing a British parasite emerged from Sphinx liguslri, probably 

 represented the present species, but 1 consider it certainly a 7 rogiis ; and 

 Curtis, recording it from Darenth Wood, adds " I believe it has been 

 bred from the caterpillar of Sphinx ligus/ri." Donovan (Brit. Ins. iii, 

 56, pi. xciii) roughly figured the female in 1794. and says it is not very 



commonly found in May and June. Hope took it at Netley and Bignell 

 on 2ist June at Bickleigh. I have specimens from Painswick in (jIos. 

 (Watkins), the Isle of Wight (Morey) and Whitby cm igth August, 1X97 

 (Beaumont). Stephens took it at Darenth.

Extremely like the last species and doubtless hitherto mixed with it in 

 Britain, whence it has not been recorded. Therefrom it differs in its 

 apically nodulose basal segment, the lower interception of the nervellus, 

 much more strongly antefurcal submarginal nervure, which is no longer
