transparent, completely revealing the castaneous coloin- of the insect. 

 I have still been unable to determine the exact food-plant of the sj^ecies, 

 as the herbage (consisting of grasses and sedges) upon which it occurs 

 is so closely intermingled ; but I believe that it more particularly affects 

 various species of Carex. 



Eriopeltis festiicae Fonscol. 



Neither Signoret nor Newstead has described the male puparium of 

 this species, though the former figures it — on a very small scale. I have 

 found examples on the upper svu'face of the leaves of Fesiuca, in close 

 proximity to the female sacs. The puparium is elongate, with rounded 

 extremities ; of a granulate, semi-transparent, glassy texture, with a 

 slight indication of a medio-longitudinal carina ; a large operculum 

 covering the hinder extremity, but without other subdivisions. Length 

 1*75, breadth approximately 0'5 mm. 



Z,iiziilasj)is luziilae Dufour. 



This species occurs, at Camberley, on Carex oval is, in addition to 

 its normal food-plant {Luzula). Newstead states that "the eggs remain 

 throughout the winter in the ovisac, the larvae hatching in spring." 

 This is probably the normal condition ; but a few larvae have hatched 

 out, in my laboratory, in the middle of July, from freshly constructed 

 ovisacs taken early in the same month. There is possibly a partial 

 second brood, while the bulk of the eggs remain as such through the 

 winter. The newly hatched larvae already have the stout stigmatic 

 spines strongly developed. 



Ceroplastes ruscl L. 



Examples of this beavitiful little species have been sent to me, on 

 the fruit of green figs imported from Italy. Though it cannot be 

 regarded as an indigenous British Coccid, it is in the same category 

 with Parlatoria zizyplii and Lejudosaphes citricola, wdiich are included 

 in the British list on the strength of their occurrence ixpon imported 

 fruit in our markets.

A note on JRhizotrogus ochracem Knoc?i. — Dr. Sharp informs me that 

 some doubt is supposed to exist as to the specific distinctness of this 

 insect from H. soLstitialiti L. For many years 1 have been well acquainted 

 with both species, which occur in a part of north Cornwall fiequejitly
