life-history of the lai'va he docs not give ; but he mentions that from 

 his observations on atra and dispnr, he has no doubt about their dis- 

 tinctness. It is also stated by Dours {lib. cit.) that the krva o£ atra 

 " vit sur les Ribes, les Salix ; " he also giving dispar as a distinct 

 species ; while, on the other hand, Dietrich (Mitth. d. schweiz. ent. 

 Ges., ii) regards it as a variety. If the observations of Eudow and 

 Dours be then correct, there can be no hesitation in treating dispar 

 as a good species, since its larva is attached to Scahiosa succisa, on 

 which it feeds in July and August. It has the head black, except the 

 face, and at the sides, which are green, the eyes being situated in the 

 dark portion. Body dark green ; the folds of the skin marked with 

 black, and aci'oss the back there are darker green stripes proceeding 

 from the edges to the centre, but still remaining apart ; below the 

 spiracles the sides are of a lighter green, and the feet are of 

 the same colour. Across the skin there are also whitish raised dots 

 — two rows to a segment, — and the head bears a few scattered 

 hairs. "When alarmed or touched, it rolls itself up into a ball, and 

 ejects a brownish liquid from the mouth. I could not see if anything 

 issued from the sides, as iii the Cimhicidcs. AVhen full-fed, it became 

 of a glassy light green colour, and proceeded to pupate in the earth. 



Length, 13-li lines. 



Tenthredo mesomela, L., sec. Thorns, (riridis, Kl.)— The following 

 is a diagnosis of the hitherto undescribed larva of this species : Head 

 deep shining black ; mouth parts pale ; upper part of the body deep 

 black ; sides pale, spotted with pale brown ; feet white, claws black. 

 Body covered with white tubercles and short hairs. Full-fed : shining 

 olive-green ; pupates in the earth. Length, 12 lines. Food-plants : 

 Banunculus, Heradeum, and apparently others. 



Emph/tus calceatus, Kl. — Last year I was fortunate enough to 

 discover the larva of this Emplytas at Fossil Marsh, feeding on Spiroia 

 nhnaria. It has the head deep black, with the mouth parts paler. The 

 upper part of the body is slaty-black, often with a greenish tinge ; the 

 rest of the body, with the feet, white, the claws being also ol' this 

 colour. The skin is wrinkled and furrowed, and bears a few hairs. 

 The spiracles are darkish. In confinement, it passed the pupa state in 

 bramble stems, and in form and habits does not differ from the other 

 larvfe of the genus. Length, 12 lines. AVith regard to the imago, I 

 may add that I have in my collection a specimen without a coloured 

 band on the abdomen.
