was lost, but the pupa was preserved and the accompanying drawings 

 were made from the specimen. 



This species belongs to the same group as pitUcaris Linne of Eu- 

 rope, and is a persistent biter. On April 15, 1914, the writer was bitten 

 by this species at Carmi, on the Little Wabash River. It was in the 

 afternoon, contrary to the general custom of these species, as they gen- 

 erally flv in the evening, and the red spot produced by the bite was no- 

 ticeablefor at least five hours. The species is larger than pulicaris, and 

 the bite more severe, as the writer can testify from his own experience. 



At Dubois both sexes of varipennis were beaten from an evergreen 

 plant — a favorite resting place for most of the species according to the 

 writer's knowledge of their habits both here and in Europe — and sub- 

 sequently a large series of females was taken on a horse which was left 

 in the yard for a short time. It was early in the afternoon when these 

 were taken, but immediately after a slight shower and when the sun 

 was not shining. All were taken on the lee side of the horse, but 

 whether they approached from that direction was not ascertained. An 

 examination of some cows which had just come in from the fields 

 produced a few specimens, mostly attached to the tender parts close 

 to the upper extremities of the legs. It was somewhat difficult to de- 

 tach the flies, as they bore well amongst the hair and retain their hold 

 very firmly. While many specimens of this species were obtained 

 from the horse when it w^as near the house, only one was taken from it 

 when it was in the woods a mile or so from the house. There, the 

 species most common was sanguisugus Coquillett, the habits of which 

 are mentioned in the notes on that species (pp. 301-302). 



Two males and one female were taken at light at Mr. Hinkley's 

 farm, Dubois, April 24, 191 4. 



Varipennis was described by Coquillett from specimens obtamed 

 at Las Vegas Hot Springs, N. M. I have examined specimens of this 

 species in the collection of the U. S. Bureau of Biological Survey 

 taken on Graham Mountain, Arizona, in May and June, 1914, some of 

 them at an altitude of 3200 feet.
