various spots on the elytra, the abdomen and femora, darker. 
In shape much like pedestris, but rather more parallel-sided 
and compact, its surface quite dull, the puncturation finer, 
the pronotum a trifle shorter, with the sides straighter and 
the base shorter in proportion to the anterior margin, 
giving it a more quadrate shape ; elytra with the membrane 
smoky, the base and the nervures pale, showing rather 
vividly against the darker ground; legs with the femora 
dark except at the apex, anterior pair with a few stiff hairs 
along their underside. 
L. 2-3 mm. 
Common and generally distributed in moss, at roots of 
grass, etc. 
PERITRECHUS, ivd. 
A genus of numerous species, most of which are so 
closely allied that it is doubtful whether they should be 
treated as distinct or only as races of one variable species. 
This condition of things exists also in Scolopostethus, and 
T have in this work given all the so-called species as dis- 
tinct in both cases, without intending thereby to express 
my opinion that they really constitute species of equal value 
to those recognized in other genera, but in order that 
Hemipterists may have the opportunity of judging for 
themselves as to what they consider the value of a species 
in such genera. 
Face triangular; eyes large, or medium-sized, projecting 
more or less beyond the pronotal angles; antenniferous 
tubercles angular at the sides, rostrum reaching to the 
intermediate coxe ; pronotum trapeziform, sides behind 
the middle narrowly foliaceous and pale, base sinuate; scu- 
tellum with a distinct central line; elytra with the 
membrane fully developed; legs with the anterior femora 
more or less incrassated, armed beneath with one or two 
fine spines ; tibize simple, without bristles, or with a few on 
the inner apical margin of the posterior pair in luniger.
