spots placed in a longitudinal row. The last molt takes 

 place in about three weeks. 



The imagoes of the summer brood appear during July and 

 those of the fall brood in September. While feeding upon 

 the tent caterpillars in the spring this bug is frequently 

 devoured by two spiders, Epeira strix and Phidippus mulli- 

 formis, which are common occupants of the caterpillar webs.

Prof. C. P. Gillette has been so kind as to send me the 

 type and only known specimen of this beautiful species. Its 

 prominent characters are : 



Length, 14 mrn. Body ovate, like P. placidus, but much larger. 

 Upper-surface dull olive colored, punctate with black. Head 

 quadrangular, lateral lobes longer than tylus, but not as long as iu 

 P. cynicus. The sides of the tylus are margined anteriorly with 

 yellowish. The entire upper surface of the head, aside from the 

 preceding, is heavily punctate with black. First segment of an- 

 tennae not extending beyond lateral margin of head, yellowish ; 

 second segment hardly longer than head, testaceous; third seg- 

 ment two-thirds as long as second ; fourth and fifth segments of 

 nearly equal length, each about three-fourths as long as second, 

 and, in common with the third segment, black except at base, 

 which is yellowish. Rostrum of medium size, not as short as in 

 P. cynicus, reaching upon middle coxne. Second segment of ros- 

 trum reaching on the fore coxae ; third and fourth segments of 

 nearly equal length; fourth segment piceous.
