very long and extremely slender feelers and legs. A transverse 
incision occurs in the vertex in front of the ocelli. The four- 
jointed feelers are elbowed at the base of the second joint, and 
the tip of the terminal joint is enlarged. The beak is also four- 
jointed; the membrane of the wing-covers is furnished with a 
very few veins. Their colors are chiefly sober tawny or pale 
yellow, with markings of black and white. To show the gen- 
eral appearance of these crane-fly like beings, the illustration of 
Jalysus Spinosus Say has been prepared, Fig. 69. In this species 
the vertex is not furnished with a prominent spinous process, but 
possesses a distinct carina; there is a small spine on the scutel- 
lum, and one on each side of the thorax in front of the coxa. 
The insect measures about one-third of an inch in length, is 
rather sluggish, and occurs in the undergrowth of oak woods. 
FAMILY COREIDAE. 
(Squash-bug Family). 
This is one of the most extensive families of true bugs, and 
is divided into many sub-families. It is characterized as follows: 
“The antennz are inserted above an ideal line extending from 
the eye to the base of the rostrum, and are four-jointed; the 
vertex is not transversly impressed; the ocelli are present; the 
rostrum is four-jointed; the scutellum is small or of medium size; 
the wing-covers are usually complete and composed of clavus, 
corium and membrane; the membrane is furnished with many 
veins, which spring from a transverse basal vein, and are usually 
forked; the tarsi are three-jointed.” (Comstock). 
The family contains both vegetable feeders and carnivorous 
forms; in some cases the same species will feed upon both plants 
and insects. Only a few of the more common species will be 
described and illustrated. 
The sub-family Leptocorisina forms a sort of connecting 
link with the bugs just described and the following ones. Here 
the body, feelers and legs are also long, but not so slender as 
in the Berytide. The head has two protracted lobes with a gut- 
ter between them, or these are separated. The best known mem- 
ber of this sub-family is the box-elder bug, (Leptocoris trivittatus
