Tabanus dodgei Whitney. Canad. Ent., xi, 37 (1879); Hine, Ohio 

 Naturalist, v, No. 2, 236 (1904). 



The coloration of the abdomen makes this species a distinct 

 one from any known to the writer. There are one $ and two 

 9 $ before me, a pair taken at West Point, Cuming County, 

 and the odd $ at Broken Bow, Custer County, June. 



Tabanus rhombicus Osten Sacken. Prodrome, ii, 472 (187G); West. 

 Dipt., 218 (1877); Hine, Ohio Naturalist, v, No. 2, 242 (1904). 



There are several specimens before me that agree with 

 Osten Sacken's second form of rhombicus, that is, the lateral 

 triangles on abdominal segments 2-5 are oblique; the inter- 

 mediate triangles show a tendency to a linear prolongation of 

 the apex toward the next segment ; the subcostal cell is nearly 

 hyaline ; the subcallus is not denuded ; and there is no stump 

 on the anterior branch of the third vein. Hine in "The 

 Tabanidae of Western United States and Canada" makes the 

 statement that he believes Osten Sacken's second form of 

 rhombicus to be centron. Hine further states that the dis- 

 tinguishing character that separates rhombicus from centron 

 is the color of the abdomen, it being black and covered with 

 a white pubescence in rhombicus and largely red in centron 

 The specimens before me have the venter colored as in 

 rhombicus.
