may be considered typical, is fulvous, with the borders 

 broadly black, and a bioad black band towards the tip 

 of the fore wings. In E. Oli/mpiu the tip is broadly black, 

 with a large white spot. In the last group, comprising 

 E. Cleobaa, &c., which sometimes measures three inches 

 across the wings, the species are banded and spotted with 

 black and tawny, and with ochre-yellow beyond the middle 

 of the fore wings, nearly as in Lycorea or l\Jeli/i(sa. 



Fritz Miiller has lately proposed to introduce the genera 

 Colcenis and Dione into the Heliconiiicje, considering that 

 their reseu)blance to Heliconius and Eueides is so great, 

 both in structure, habits, and transforu)ations, that the 

 difference in the wing-cells ought not to be considered; but 

 I do not v\ish to disturb the usual arrangement in the present 

 series of papers.

ICHNEUMONS.=i= 

 By Edward A. Fitch. 



" The most formidable difficulty in the way of the investiga- 

 tion of some of what 1 have called the ' neglected orders,' is the 

 want of accessible handbooks." So says Dr. Parsons in a 

 paper, on the general study of Natural History, read before 

 the Selby Naturalist's Society (see the 'Naturalist,' December, 

 1877, and January, 1878). This paper contains many worthy 

 hints, which deserve to be borne in mind and acted upon by 

 entoujologists especially, and sets forth many important 

 truisms. The study of the terebrant Hymenoptera has been 

 greatly retarded in Britain by the want of accessible hand- 

 books. However we have one now in course of publication 

 which will certainly be a great help to the student of the 

 enlomophagous section of this interesting class of insects. 

 The author has also been the elucidator of the life-histories 

 of the phytophagous sawflies, many of which have been 

 translated into the pages of the ' Zoologist' and ' Ento- 

 mologist.' 



Of the neglected Ichneumonida) we have, thanks to Mr. 

 Marshall, an excellent catalogue; but I believe there is by
