to him drawings of this species from specimens taken at De 

 Grasse Point, Lake Simcoe, Ontario, Canada. 



The first capture of this species which has come under my 

 notice was by Mr. Chas. W. Johnson, at North Mountain 

 (Ricketts), Sullivan County, Pennsylvania, in September, 

 1897. ^ number of specimens were collected in a section 

 from which hemlock had been recently cut, the species being 

 rather abundant. In August, 1900, I received several speci- 

 mens collected at Bellasylva, Wyoming County, Pennsylvania, 

 by Mr. Otto Behr. Mr. Behr is a resident of that section, and 

 his statement is to the effect that the species always occurs on 

 the branches of the hemlock, and that, on removal, they will 

 immediately return to the same. 



The third instance I know of is the capture of a single spe- 

 cimen of this insect at Ganoga Lake, Sullivan County, Penn- 

 sylvania, by Mr. Stewardson Brown, on September 2, 1900. 

 Mr. Brown states that the specimen was captured in a clearing 

 in a woods containing hemlock, birch and maple, it being the 

 only one observed. 



Quite recently a specimen has been presented to me me by 

 Mr. W. S. Huntington, who collected it at Glen Onoko, Car- 

 bon County, Pennsylvania. The specimen is a male, and was 

 collected in grass, it being the only one observed. 



From the above recorded captures it is very evident that 

 hemlock exercises a very strong influence over this insect ; for 

 while the last-mentioned capture was not taken in hemlock, 

 there undoubtedly is hemlock somewhere in the vicinity, and, 

 while it is not the prevailing tree, it is there in moderate num- 

 bers at least, that is the writer's experience not far from that 

 locality. 



From present indications the occurrence of this insect may 

 be expected in any section of the State which contains moder- 

 ate quantities of hemlock.
