420 FIFTH REPORT OF THE ENTOMOLOGICAL COMMISSION. 
transverse carina at base of head very slender, the former nearly as long as the heme- 
lytra. Surface of head polished, impunctured, clothed with short hairs. Tylus slen- 
der, short. Eyes large, prominent Pronotnm smooth, very convex, sparingly hairy. 
finely, densely, end mostly continently pnnetnred, the pnnetores forming obsenre 
transverse rugosities. The head and forepart <>f the thorax are slightly darker yel- 
low, the antenna- are sometimes pale throughout, sometimes emlirowned at tip and 
■ISO at tip of second Joint. A broad band on the pronotnm. a little within the mar- 
gin, extends backwards along the inner edge of the calvus, is continued as a dusky 
shade through the middle of the membrane, deepest along the inner ed^e of the inner 
cell, and extends distally into an indefinite dusky shade. This line is intersected at 
the tip of the corium by a transverse baud of the same color, extending to the edge 
of the hemelytra. When the wings are closed, these marks give the appearauce of a 
median black stripe crossed at the tip of the corium by a black baud, and forking at 
the scutellum. In the darker colored specimens the prouotal bands are frequently 
connected by a basal shade. The posterior half of the larger cell of the membrane 
is usually white. In many yellowish specimens the cuneus alone is green. The pos- 
terior thighs are commonly iufuscate on the distal half, and the anterior tibia- are 
often brown at tip. Length to tip of hemelytra 6 mm . Humeral breadth 1.6G ,,1In . 
On the 12th May the younger leaves of many of the common soft maples (Acer dasy- 
carpum) near Normal were observed to be curled and specked with numerous semi- 
transparent spots, evidently the work of the larvae of this Capsid, found abundantly 
upou the affected leaves. On the 30th May specimens collected were all of the sec- 
ond and third stages. On the first of June, the first imagos were seen iu the breed- 
ing cages and on the trees. By the 5th of that mouth nearly all the specimens col- 
lected had transformed to the imago, and the experiment was not carried further. 
61. Poecilocap8U8 goniphorus (Say). 
A brilliant scarlet red bug found on different trees, including the maple. 
62. Lygus monachus Uhler. 
The following account by Miss Murtfeldt of this bug appeared iu her 
report as special agent of the Division of Entomology (Bulletin 
No. 13) : 
This bug came under my notice for the first time late in the spring of 1882, infest- 
ing the growing points of young soft maples (Acer dasycarpum). Most of the insects 
were at that time mature, but two or three pupa? were found, enough to indicate that 
the leaves of the maple had been their breeding place. A few specimens were taken, 
but as the insect was not present in sufficient numbers to give it importance as an 
injurious species, not much attention was paid to it. During several succeeding 
springs I occasionally came across a mature specimen — which, from its exceeding 
agility, both in running and flying, generally evaded capture— but it was not until 
the present season that the maples were infested to such an extent as to injure and 
disfigure them. 
Just as the leaves were beginning to put forth, close observation revealed the fact 
that they were all more or less stippled with transparent spots, some mere dots, 
others a tenth of an inch or more in diameter. As the leaves expanded the delicate 
cuticle of the upper surface would give way and they presented the appearance of 
being perforated with holes and much torn and tattered along the margin, marring 
their beauty for the entire season. If, about the 1st of May. the leaves were care- 
fully examined, there would be found on the under surface of each from two or three 
to a dozen or more very delicate bugs of a very pale translucent-green color, the 
embryo wing-pads being almost white. They were further characterized by very long 
and slender legs, beak, and antenna?, body flat and broad oval in outline ; head small,
