112 MAINE AGRICULTUIL.\L EXPERIMENT STATION. I915. 



The larval form -of this species has a characteristic black border run- 

 ning from the head along the sides to the last segment of the abdomen 

 narrowing sometimes in the central part of the abdomen and the included 

 area is yellow or in some cases bright red for the central part. 



As the larvae are usually found in grass or weeds and low herbage 

 along fences and roads it is probable that clean culture and the burning 

 of leaves and litter where practicable will have a good effect in reducing 

 the numbers.

A single specimen of this species was taken at Mars Hill Aug. 25th, 

 also one specimen Ft. Kent Aug. 28th. These are exact duplicates of the 

 type specimen which was collected by Mr. Van Duzee at Phoenicia, 

 N. Y. Several females and males taken at Orono Aug. 5, 8, 11, 22, 24,
