38 NONAGRIA FULVA. 



a narrow plate on the front part of the anal segment ; 

 the dusky-brown tubercular dots were most minute, as 

 usual with internal feeders they were largest on the 

 twelfth segment, and were there just perceptible (by 

 the aid of a strong lens) each bearing a short bristle ; 

 the ventral surface was pale flesh-colour, the anterior 

 legs light brown, the whole skin shining. 



When about to pupate all the stripes disappeared, 

 and the skin became of a porcelain-white, strongly con- 

 trasted with the black spiracles. 



The pupa was of a slender figure, measuring five- 

 eighths of an inch in length, very uniform in substance 

 throughout ; the thorax rather short and convexly 

 rounded ; the head sloping forward was prolonged with 

 a slight tendency to a beak, though rounded off at the 

 very tip ; the wing-covers short in proportion to the 

 length of the body, from the moveable segments of the 

 body below them being longer than usual; the last 

 three tapered a little, ending in a short blunt thorny 

 projection ; the colour was light brownish-ocbreous 

 with a faintly darker dorsal stripe, the anal projection 

 dark brown, and the whole surface very glossy. (W. B.,

My best thanks are due to Mr. James Batty, of 

 Sheffield, who took a long journey during inclement 

 weather that he might search for the larva of this 

 species, comparatively new to our lists ; and it may be 

 supposed how much I rejoiced at the success of his ex- 

 pedition, when on the 16th of May last I had the 

 pleasure of receiving from him a consignment of grow- 

 ing plants of Elymus arenarius containing several full- 

 sized larvae. 



Of course I am not able to give any account of their
