;it llio base of t lie tail, which is of the same colour; hciualh the former are 

 several oblique purplish streaks placed over the sti|^mata: it fcvils on the 

 devil's-bit scabious ( Scahiosa succim). The chrysalis is brown. 



This is decidedly the rarest species of the gcmis near l.oii(U)ii ; 

 though near Enborne, in Berkshire, I was informed by Mr. Dale, 

 that he formerly captured it in great plenty, at the end of May and 

 beginning of June. It is probably a native of Cambridgeshire. 

 " 1 am almost certiiin it appears in certain seasons in the fens about 

 the middle of May : Professor Henslow saw several specimens this 

 year in Horningsea-fen, and last year I also noticed one or two at 

 Wood Ditton; but neither of us have succeeded in capturing a single 

 specimen : its food, the scabious, abounds in the fens." — Rev. L. 

 Jemjns. " New Forest, Hants, in May last." — Mr. Weaver.

Upon the dispersion of Mr. Plastead's collection I obtained a fine pair of this 

 species therefrom; but as it is indigenous to North America, I conceive that 

 the ends of science will be more advantageously benefited by the simple indi- 

 cation of the fact, than by giving the insect as an inhabitant of this country, 

 which the mere detection of specimens in a collection does not warrant ; but. 

 on the contrary, as this insect was considered by Mr. Tlastead as the Sp. Fusi- 

 formis, it is evident that he did not scruple to admit /;./•< /y/t specimens into 

 his cabinet.
