but which deserves attention as the near relative of one of . the most 
injurious horticultural species (the tarnished plant bug), and also 
because, from its own abundance and habits, it may well become 
the author of serious mischief. 
Although not agreeing precisely with any descriptions of Capsids 
accessible to me, I have little doubt, after careful study of about 
forty specimens collected in June, that the species is that described 
by Say as Capsus invitus. It differs materially from Say’s original 
descriptions, but corresponds closely in most particulars with the 
description of a type specimen of Say’s, published by Uhler in his 
notes on the Heteroptera in the collection of Dr. Harris, * varying 
from that only in some color characters of little moment in so vari¬ 
able a genus. 
DESCRIPTION. 
The following description is condensed from that of Uhlei, modi¬ 
fied with respect to color to conform to our own specimens. 
General color pale obscure yellow, varying to yellowish green. 
Antennae and transverse carina at base of head very slender, the 
former nearly as long as the hemelytra. Surface ot head polished, 
impunctured, clothed with short hairs. Tylus slender, short. Dyes 
lame prominent. Pronotum smooth, very convex, sparingly hairy, 
finely densely and mostly confluently punctured, the punctures 
forming obscure transverse rugosities. The head and fore part ol 
the thorax are slightly darker yellow, the antennae are sometimes 
pale throughout, sometimes embrowned at tip and also at tip ot 
second joint. A broad band on the pronotum a little within the 
margin,' extends backwards along the inner edge of the clavus, is 
continued as a dusky shade through the middle of the membrane 
deepest along the inner edge of the inner cell, and extends 1 ■ . 
into* an indefinite dusky shade. This line is intersected at the tip 
of the corium by a transverse band of the same color extending to 
the edge of the hemelytra. When the wings are closed, these marks 
give the appearance of a median black stripe crossed at the tip o 
the corium by a black band, and forking at the scutellnm. In the 
darker colored specimens the pronotal bands are frequently con¬ 
nected by a basal shade. The posterior halt ot the laiger cell of 
the membrane is usually white. In many yellowish spemmens the 
cuneus alone is green. The posterior thighs aie < omnu ' 
on the distal half, and the anterior tibiae are often brown at tip. 
Length to tip of hemelytra 6 mm. Humeral breadth l.bb mm. 
On the 12th May the younger leaves of many of the common so 
maples (Acer dasycarpum) near Normal, were observed to ^ muled 
and specked with numerous semi-transparent spots, evidently t 
work of the larvae of this capsid, found abundantly upon e a^ ec ^ 
leaves. On the 30th May, specimens collected were all of the se o 
and third stages. On the 1st June, the Ins month 
in the breeding cages and on the trees. By ie o • ' an( j 
nearly all the specimens collected bad transformed ’ 
the experiment was not carried farther.
