July from pupae received from Mr. W. F. Avera, editor of the Ouachita 

 Herald, of Camden, Ark., who had noticed the larvae damaging cot- 

 ton. This parasite has been de- 

 scribed by Mr. Ashmead on p. 437 

 of the Proceedings of the U. S. Na- 

 tional Museum, Vol. XII, 1889, as 

 Limneria eurycreontis,&na\ we pre- 

 sent herewith a figure of the fe- 

 male sex. The eggs are laid in 

 the larvae and those specimens 

 which we reared issued from the 

 pupae. Many Limnerias, it will 

 be remembered, issue from the 

 larvae of their hosts before the 

 latter have transformed. 



We also reared about the same 

 time, from the same lot of web- 

 worm pupae, specimens of a Bra- 

 conid parasite, which we have de- 

 termined as Mr. Cresson's Agathis 

 exoratus.

AN APHIS ATTACKING CARROTS. 



In his report as State entomologist of New York, for the year 1886, 

 p. 123, Prof. J. A. Lintner records the reported appearance of Aphides 

 on carrots and parsnips, at Oakley Park, Mass., in sufficient numbers 

 to seriously injure the crop. As no further particulars or specimens 

 were furnished the professor, and as this is the only case on record 

 where the carrot in this country has been attacked by Aphides, we are 

 left totally in the dark as to what particular species was engaged in the 

 depredations. 



Buckton* states that Siphocoryne pastinacw (Linn.) was found abun- 

 dantly on carrot, at Haslemere, in July, and Curtis t says that in 1847 

 a field in Gilford, Surrey, was about one-tenth destroyed by an attack 

 of Aphis dauci (Fab.), and another species of Aphis occurs in October 

 about the roots. Miss Ormerod £ tells us that a serious attack occurred 

 at Newton Farm, near Glasgow, in 1879, and also states that carrots 

 are attacked by several kinds of Aphides, among them Aphis papaveris 

 Fab., which infests the leaves, and A. carrotw, which affects the flower 

 stems, and also the below-ground portions of the plant. M. Lichten- 

 stein § names in his list seven other species which infest the carrot, three 

 of them attacking the parsnip also.
