86 Mr. J. W. Douglas on the genus Orthezia. 



described and figured by Dr. Signoret as appertaining to 

 the n^'mph, or what he, with some hesitation, regards 

 as the nymph-form, of Gossyparia ulmi, Geoffr., and 

 which he terms "moignons d'elytres " (Ess. Coch., 

 pp. 318 and 320, pi. 15, fig. 2 6). I can find no trace of 

 these wing-sheaths in the pupa-skin. 



The objects represented by the figures 5 and 7 having 

 been mounted in Canada balsam are thereby rendered 

 transparent, and the segmentation of the bodies, as well 

 as the base of the projections on No. 7, is not clearly 

 recognisable.
