Head lutescent, with a streak in front adjoining the eyes, and the edge of the 

 labrum black; eyes fuscous, greenish beneath; thorax above dull red, with 

 two irregular approximating black streaks on the sides, which last are 

 luteous ; abdomen also dull red or flavescent ; the basal segment, the apex 

 of the 5th, and the remainder black, the 4th to the 8th with a luteous spot 

 on each side ; anal appendages black, upper pair clarate, lower acute ; legs 

 black; wings hyaline, saffron-coloured at the base, with a spot in the 

 middle of the costa, and the stigma black or fuscous, the hinder pair with a 

 large somewhat triangvdar fuscous patch, reticulated with yellow. 



The costal spot varies in size, and is sometimes a little ocellated, and at others 

 nearly wanting. 



Found at Muswell Hill, not uncommonly, in June and July, and 

 abundant near Godalming and Epping; also at Whittlesea Mere, 

 &c.

Appendix. 



Head brown, with two yellow spots behind the eyes; abdomen brown, 

 slightly attenuated, the five or six intermediate segments with a luteous 

 spot on each side ; wings as in Li. 4-maculata, but the central spot is sur- 

 rounded by a brown cloud, and from the stigma a transverse fascia of the 

 same colour extends sometimes completely across the wings, at others but a 

 short distance, and at times nearly obliterated ; legs black. 



Whether this be really a distinct species I am not prepared to affirm ; but its 

 characters appear sufficiently distinct to constitute one ; it is rather larger, 

 and its abdomen is less pilose and broader at its extremity than in Li. 4-ma- 

 culata, of which it is generally considered to be a variety. 



Abundant about Epping and Godalming ; .also taken in Burwash 

 fen. Cambridgeshire, in the beginning of July.
