LOUISIANA CIRCULAR No. 6. 41 



"On June 14, 1905, while coming into Shreveport un the Kansas 

 City Southern Railway, and while standing on the rear platform of 

 the last car, I noticed two of these insects following the train, and 

 occasionally alighting upon the coach. The train was running about 

 twelve miles an hour and was a few miles out of Shreveport. I suc- 

 ceeded in capturing but one of the two specimens." (Newell). 



Mr. Garrett made the following note at Logansport on September 

 6: "These flies usually attack the horses' legs and are quite annoying, 

 for when they have once settled the horse can hardly get rid of them. 

 They are quite numerous at this date." 



Again: "These little insects were taken from the legs of horses 

 which were being driven to a buggy. They usually alight on the horse's 

 leg between the hock and the hoof, and are rather difficult for the 

 horse to drive off, which he usually tries to do by stamping or kicking." 



TABANUS FULVULUS Wiedemann. Length, three-fifths of an 

 inch. Some specimens are larger and some are smaller. Thorax with- 

 out stripes; wings with the anterior margin narrowly yellowish, but 

 otherwise hyaline; abdomen with a median dorsal band and a row of 

 spots on each side, whitish or yellowish. It differs irom ' T. sagax by 

 having the femora yellowish instead of blackish, and the third seg- 

 ment of the antenna is not so plainly angulated above as in that 

 species. It is known from Kentucky, Maryland, North Carolina and 

 New Jersey, and appears to be common near the seacoast. Taken from 

 ;a horse that was being driven to a buggy, June 17, 1905, near Crowley, 

 in the southern part of Louisiana (Martin). 



PlG o Say's horsefly (Tabanus molestits), female, en- 

 larged to one and a half diameters. 



TABANUS MOLESTUS Say (Say's Horsefly). The thorax is dark- 

 brown, plainly striped with gray; the abdomen is black, with the po< 

 terior margin of each segment narrowly gray, expanding into a promi- 

 nent triangle at the middle of the third, fourth and fifth segment^ 

 There is also a small triangle on the second segment, but It 1 so 

 small in comparison with those on the following segments th< 

 hardly noticeable. Wings subhyaline, veins brown, but not margined
