Cap. — Generally ovate in outline, from exterior of plant; some- 

 times with sides slightly concave. Margin of cap finely serrate on 

 edge ; ridged on inner side, the ridges corresponding to the serrations. 

 A series of hairs, arranged quite regularly, joins the lower, outc 

 edge of the cap with the pellicle and apparently holds the cap in 

 place. Color within the margin, yellowish green. (This may vary 

 with the state of development of the Qgg). 



The cap bears a short, stout spine which is attached on the con- 

 cave side of the egg. The spine is rigid, but flexible at the base, 

 wdiere it joins the margin. Spine enlarged slightly and rather abruptly 

 at tip and projects for its entire length outside the epidermis of the 

 plant. Color pale reddish; length .16 mm. 



According to insectary records, from 11 to 13 days were required 

 for eggs to hatch; this in the latter half of July and the first half of 

 August. 



The Xymphal Stages. 



Dr. Forbes^ studied this species as a strawberry insect and pub- 

 lished descriptions of certain of the nymphal stages. Forbes, how- 

 ever, was under the impression that there were but four nymphal 

 stages, whereas the actual number is five. The stages described by 

 him as IT, III and IV are, in reality. III, IV and V. Descriptions 

 of the five stages follow. 



Stage I. — Head and prothorax brownish ; meso- and metathorax 

 yellowish, sometimes greenish; abdomen pale clay yellow; body 

 sparsely setaceous, setae black; length 1.4 mm. 



Head including eyes slightly wider than prothora.x ; eyes deep 

 rose ; antennae pale cadmium yellow, except last segment, which is 

 deep red, white tipped and with a somewhat broader white band at 

 base; sparsely clothed with fine white hairs; beak long, the tip extend- 

 ing well on to the abdomen, color pale cadmium yellow, tip dusky. 

 Prothorax narrower than succeeding segments, about one fourth 

 longer than mesothorax, distinctly margined ; mesothorax nearly twice 

 the length of metathorax ; metathorax short. 



Abdomen ovate, broadest before middle, pale clay yellow except on 

 margins and apex of venter, where it is pale cadmium yellow. 

 Femora pale cadmium yellow, hind i)air slightly darker; tibi.T pale
