CROP PEST COMMISSION OP 



in other months also. Following are some of the records of capture: 

 Many, May 19 (Newell); Montgomery, June 29; Gloster, July 14; 

 Frierson, July 14; Keachie, August 23; Logansport, September 6 

 (Garrett); Foresthill, September 8 (Newell). 



The following observations on this fly were made by Mr. Garrett: 

 "These insects were numerous and very annoying in the vicinity 

 of Logansport. They almost invariably attacked horses' ears and very 

 frequently left them covered with bjood. They were most numerous 

 near creeks and bayous, but were found to some extent in higher 

 places." 



CHRYSOPS VITTATUS Wiedemann (Striped Earfly). This is a 

 common species all over the eastern United States, and was taken 

 in many localities in Louisiana the past summer. It is usually larger 

 than the last two species mentioned above, but is about the same size 

 as C. flnvidus. In general appearance it is more yellowish than most 

 species of its genus; the stripes on the thorax are bright yellow 

 and conspicuous; the black stripes on the abdomen are narrow and 

 composed of a series of elongated spots joined end to end. The fol- 

 lowing records indicate its general distribution and time of appear- 

 ance: Montgomery, June 29; Gloster, July 14; Lecompte, June 8 

 (Hardy) ; Logansport, September 8 (Garrett) ; Foresthill, September 8 

 (Newein. 



The following observations upon its habits were made by Mr. 

 Newell : 



"During several days of traveling through southwestern Rapides 

 Parish, between Lecompte, Woodworth, Foresthill and Glenmora, I 

 encountered this species wherever low or swampy valleys were crossed, 

 especially where the growth of underbrush was dense. The flies at- 

 tacked the necks and . ears of the horses, both being often covered 

 with blood from their vicious bites. In a swampy area on "Spring 

 Creek," southeast of Glenmora, I counted as many as 1 twenty-five on 

 the ears of my horse at one time. This species was not found in the 

 long-leaf pine timber, but only in the creek bottoms running through 

 the 'piney woods' country. This fly evidently does not attack man, 

 as at different times I approached large numbers of them flying about 

 the horses' heads, for the purpose of capttfring specimens, but was 

 not once bitten. After a few individuals were captured the rest 

 usually became alarmed and flew away. The individuals which were 

 engorging themselves with blood, on the other hand, showed no fear 

 and stuck so tenaciously to the animals that it was almost impossible 

 to remove them without injuring them as specimens." 



TABANUS ATRATUS Fabricius (Black Horsefly). This large 

 black horsefly is generally distributed over the eastern United States, 

 and as far west as Colorado. It is entirely black, wings and all, and
