Males commenced to appear towards the eud of August. They 

 are of the form normal to the genus, of a brownish purple colour, 

 with a pair of long white caudal filaments. Antenna 10- jointed, 3rd 

 joint longest, longer than preceding two joints together ; subsequent 

 joints decreasing in size to the tenth, which is the shortest. Apical 

 half of terminal joint dense and opaque, with from four to five stout 

 curved spines at its extremity ; one or two long and slender knobbed 

 hairs on each joint with the exception of the 1st and 2nd. 



Eriococcus insignis Newst. 



Occurs commonly on grasses (usually Agrostis sp.) in the Cam- 



berley district. 



Eriococcus greeni Newst. 



This species, which was described from a single example taken at 

 Budleigh Salterton in 1896, has now turned up at Camberley, where it 

 occurs not uncommonly, in association with E. insig7iis. Owing to the 

 difficulty (noted by Newstead) of distinguishing between the ovisacs 

 of the two species, it is probable that E. greeni may be frequently 

 overlooked. The ovisac of greeni appears to me to be pi'oportionately 

 slightly broader and rougher than the other. I find also that this 

 species shows a distinct preference for constructing its ovisacs upon 

 dry fallen leaves. The inse(3ts themselves are readily distinguishable 

 by the arrangement of the spines, which in greeni are scattered thickly 

 and more or less evenly over the dorsum, while in insignis they are 

 confined to the margin where they form a conspicuous fringe. Newstead 

 describes the type as having 6-jointed antennae, the 3rd joint very long. 

 In my examples I find that the antennae are normally 7-jointed, the 

 3rd and 4th being longest and approximately equal. In only a single 

 example have I found the typical 6-jointed form. 



EbIOCOCCUS INERMIS 710V. 

 Adult female elongate oval (fig. 1-a). Derm without spines, except on the 

 anal lobes ; but closely set with conspicuous thick-rimmed pores opening into 

 tubular ducts (fig. 1-c), and some incouspicuovis spiniform hairs. Anal lobes 

 prominent; each lobe with a longish stout apical seta and two stout spines on 

 its inner margin. Anal ring with eight stout setae extending almost to the 

 extremity of the lobes. Legs moderately large ; tarsus equal to or slightly 

 longer than tibia ; claw withoiit denticle ; digittiles hair-like, dilated at 

 extremity. Antenna (fig. 1-b) 6-jointed, the 3rd very long and xisually broader 

 than the 2nd; other joints short. Occasionally there is an incomplete division 

 in the 3rd joint. Antennal formula 3, 6, 2 (4, 5). Length ranging from 1.50 to 

 2,50 mm. ; breadth from 0.75 to 1.20 mm. ; average of fourteen examples, 1.97 

 by 0.94 mm.
