20 THE ENTOMOLOGIST. 



head pale testaceous-brown or putty-colour, with dark brown 

 spots, some of which group together and form two longitu- 

 dinal stripes, one on each cheek : body pale testaceous-brown 

 or pntty-colonred, with numerous dark brown dots, which, 

 associated, form lozenges on the back, and longitudinal rivu- 

 let markings on the sides ; the perfect lozenges on the back 

 are four in number, and each has a quadrate black spot in 

 the centre ; there are two principal lateral rivulet stripes, 

 both of them double ; the lower of these comprises the black 

 spiracles, and terminates in the anal claspers ; a long black 

 spot on each side runs into the ventral claspers ; the double 

 rivulet markings of the ventral surface are five in number; of 

 these the median one is the narrowest and the palest in colour, 

 and its component parts most approximate ; the upper double 

 stripe on each side is situated just below the skinfold ; it is 

 very interrupted and indistinct, and contains five quadrate 

 black spots, namely, on the 5th, 6th, 7th, 8th and 9th seg- 

 ments ; the warts are pale, and the bristles they emit are black 

 with white tips. I am indebted to Mr. Vaughau, of Bristol, 

 for specimens of this larvae ; they changed to dark brown 

 glabrous pupae in a slight web among dry remains of the 

 food-plant on the surface of the earth. The moths emerged 

 from the 17th to the 30th of April. Guenee says of this 

 species that although it does not differ essentially from 

 C. ferrugata, except in colour, it is so constant that he is 

 almost tempted to regard it as a distinct species ; but that 

 Sepp has figured it as coming from the same larva. 1 have 

 positively verified the larva described above as being that of 

 C. unidentaria ; not that I doubted Mr. Vaughan's informa- 

 tion, but that I might have the gratification of confirming 

 him. I extremely regret to say that I am still unacquainted 

 with the larva of the common Coremia ferrugata. It appears 

 to me, however, that on the Continent our view of the names 

 of these species, or supposed species, is not exactly under- 

 stood ; for Lederer has sent specimens of unidentaria to Mr. 

 Doubleday, some with a red and some with a black central 

 band, evidently supposing them our unidentaria and ferru- 

 gata ; and also our I'errugata ticketed var. s])adicearia, Bork. 

 Now the colour of the central band in unidentaria is very apt 

 to exhibit a ferruginous tinge, so that colour taken by itself 

 is insufficient to distinguish them. I am glad to have had
