176 Records of the Indian Museum. [Vol. IV, 



The specimens from Formosa have the abdomen in females 

 more reddish yellow, the segmentations paler with yellow hairs. 

 Frontal callus a little broader and more pear-shaped. 



<f . Redder in colour than the female^ the spots on abdomen 

 are smaller and the fore tibiae dull yellowish or obscurely red at 

 base with only a few lighter hairs. E3'es large, the large facets 

 occupy the upper half but do not reach the anterior border of the 

 frontal triangle, nor the vertex where the small facets extend as 

 a narrow border. Palpi yellow, with yellow pubescence and a few 

 black hairs at apex. Length of males 17 — 2o|- mm. 



The type of Tabanus mentitm, Walker, a male from Foochow, 

 China (G. T. Lay), is probably identical, judging from its similarity 

 to the male from Formosa, but owing to its bad condition and the 

 fact of its being a male, its identity must remain doubtful till the 

 advent of more material. 



The blackish colouring sometimes surrounding the median 

 abdominal spots is more distinct than usual, as oblong black spots 

 on the second, third and fourth segments, and only on the third 

 and fourth segments is a median grey spot visible, probabh^ owing 

 to denudation, the apex of the al:)domen is blackish.
