No. 34-] HEMIPTERA OF CONNECTICUT: MIRIDAE. 631 



Legs: Coxae pale, a fuscous spot near base of lateral aspect; 

 hind femora black, marked with large and small pale spots, with 

 an oblique subapical pale band, basal one-fourth of anterior and 

 posterior aspects pale ; front and intermediate femora blackish but 

 with pale spots largely confluent so that the black color is separated 

 into streaks and spots, the blackish color most prominent dorsally 

 on apical half ; front tibiae black, triannulate with pale, basal band 

 below knee less conspicuous ; intermediate tibiae black, a black 

 band at middle separating two prominent pale bands, the third pale 

 band at apex but with tip of tibia fuscous ; hind tibiae blackish, 

 irregularly marked with small nearly glabrous pale spots, the pale 

 spots confluent for a space at middle of basal half ; tarsi fuscous, 

 paler on second segment. 



Venter : Black, somewhat yellowish along ventral median line ; 

 genital segment without tubercles, claspers distinctive (fig. 136). 



Described from a single specimen, male, 2^ Aug., 191 7, Kentville, Nova 

 Scotia (W. H. Brittain). 



Key to Species of Phytocoris, Group II. 



In this group accurate determinations can be expected only when 

 making use of the male genital claspers. Once the male is cor- 

 rectly determined, females of the same species can usually be 

 recognized by the general similarity of coloration, differences 

 which are apparent yet very difficult to formulate in a key. For 

 determining fully mature and well preserved specimens the follow- 

 ing key should prove useful but the male genital claspers should be 

 examined when possible. 



1. Corium with distinct black or dark fuscous mark across apical 



area, extending obliquely from radius across to inner apical angle 

 of coriimi, the dark mark never broken with paler irrorations ... 2 

 Corium without distinct black mark across apical area, sometimes 

 fuscous but the dark color broken by paler irrorations, but if not, 

 then the black color on radius distinctly darker than the oblique 

 inf uscation 10 



2. Pronotal disk uniformly deep black, narrow basal margin pale; 



scutellum yellowish, with an oblique black mark each side of 

 median line which begins at middle of disk and extends to margin 



at a point barely beyond middle (p. 636) nigricollis n. sp. 



Pronotal disk pale grayish to blackish, always paler on middle and 

 never deep black 3 



3. Scutellum with distinct black mark on each side of apical half 



which extends from lateral margin obliquely cephalad to near 



middle of disk 4 



Scutellum with black spot at margin each side of apical half, but 

 scarcely longer than broad, at most not extending more than half 

 way to middle of disk _ • • • 7 



4. Pale color on lower margins of propleura not extending upon sides 



of sternum _ 5 



Pale color on lower margins of propleura extending upon sides of 

 sternum ; hind femora black except at base, pale irrorations small, 

 the largest spot not wider than the narrow pale band at slightly 

 beyond middle of apical half (p. 639) husseyi n. sp.
