﻿68 New York Shitr (\)ll(f/r of Forrsirij 



sceoiul segment lif^htcr; third and fourth segments subeqiial in 

 length; second segment equal to the first and third conjoined, the 

 first slightly more than half the length of the third. Legs with 

 basal portion of femora and tarsi dark brown to nearly black, the 

 rest lighter. 



Pronotum with explanate margins narrow, distinctly and roundly 

 emarginate on the posterior border, distinctly and transversely 

 rugulose on the collum and basal portion, a smooth someAvhat 

 crescent-shaped area just back of the collum, the pubescence graj'- 

 ish, fine and mostly prostrate. Rostrum reaching between the 

 middle coxae. Head quite sparsely pubescent, its length distinctly 

 longer than its width (diameter through eyes). Male gental 

 claspers curved. Length 3.2 — o.4.1 mm.; width 1.15 — 1.27 mm. 



Numerous specimens, taken on white pine trees, at Barber Point, 

 Wanakena and the Plains during July, August and September, 

 1917, 1919 and 1920. The male is a little more slender than the 

 female. This insect seems to feed largely upon the leaf-feeding in- 

 sects of conifers, particularly white pine, Pinus fttrohus. Nymphs 

 and adults could be found at all times during the summer upon the 

 pine trees but only larger nymphs and adults during the latter 

 part of the season. There is only one generation a year. The 

 insect has been bred from the burrows of Cri/piorhynchiis lapaiJii 

 by the writer (1. c, p. 203). I am indebted to Dr. H. M. Parshley 

 for kindly comparing this insect with his types of T. concolor and 

 T. americano. 



Triphleps insidiosus (Say) (Plate 11; a). 



This is a common species in the family. It is a grass- and an 

 herb-inhabiting insect, especially common in open grassy areas. 

 It is also predaceous and adults have been reported as feeding 

 upon eggs as well as nymphs and adults of other insects. Barber 

 Point, Wanakena, Conifer, and Plains, June, July, August and 

 September, 1917, 1919 and 1920.
