tions of the body are darker and more conspicuous, and the abdominal 
tubercles more prominent. The antenna? and leg's are wider, the latter 
with the lateral tibial expansions just beginning- to show, being now 
about the same width as the tibia itself, and without teeth. The 
tubercles are larger, but the dorsal spines are scarcely longer than in 
the second stage. The haustellum immediately after the molt projects 
beyond the abdomen to a distance about equal to the length of the 
head. Length of body just after molt, 6 nim . 
Fourth stage. — The appearance of this stage is shown at d* fig. ±. 
The antenna?, hind legs, and bod}' are subequal in length, the haustel- 
lum a little shorter when first transformed, the width of the body at 
this time only a little over 2 mra , becoming about 3.5 mm before the next 
molt. When "full colored" the body is of about the same appearance 
as in the third stage, but the red ground color becomes lighter and 
duller orange before molting, while the black coloring extends farther. 
The wing pads are bronzy black, occupying mare than half the thorax; 
the tibia? each marked with a whitish band just below the middle; 
lateral expansions about two-thirds wider than tarsi, with one more or 
less feebly marked lateral tooth toward apex. Length when first 
molted, 9™ m . 
Fifth stage. — This stage is illustrated at e, fig. 4. With the casting 
of the fourth skin the nymph begins to show the appearance of the 
mature bug; the antenna? and legs are still shining black, the latter 
yelloAvish at the extreme apex, and the tarsi have each a whitish band, 
as in the preceding stage. The lateral expansions are several times as 
broad as in the preceding stage, strongly bidentate on the lateral sur- 
face, and rather feebly unidentate on the inner portion, which is 
marked with a medial white spot. The head and body are black, 
thickly covered with gray pubescence, thickest on the head. The 
prothorax is narrower at the apex, where it is of about the same width 
as the base of the head, and broader than the thorax at the base; the 
sides are nearly straight, with wide orange margin. Just behind the 
apex of the thorax there is a pair of small, rounded orange tubercles 
placed rather closely together. Length when first molted. ll mm . 
The adult. — A full description of the mature insect has been given 
b} T the writer in the article previously mentioned (p. -±5), but for the 
benefit of those who may not have opportunity to refer to that descrip- 
tion it may be stated that the parent insect is a large, chocolate-brown 
heteropterous bug of the same family as the squash bugs, the Coreidse, 
from which insects it may be readily distinguished by its more slender 
form, acutely pointed head, and longer antenna 1 and legs, but more 
particularly by the leaf -like expansion of the hind legs (see fig. 3,«). 
The length is 18 to 21 mm , and the width across the thorax 5 to 6 mm .
