iQii.] G. RiCARDO: Revision of the species of 'VabsLnas. 213 



The name is preoccupied by a Macquart species from S. 

 America. 



A small narrow-bodied species, of which no specimens are pres- 

 ent in the various collections dealt with in this paper, the type 

 and other specimen are both in a faded dirty condition, but the 

 species seems distinguished from any I have yet seen by its very 

 narrow hairy palpi ; the frontal callus is club-shaped with a short 

 rather stout lineal extension ; Bigot gives tha colour of the abdo- 

 men as light chestnut with a yellowish tomentum, which appears 

 fairly correct. Legs uniformly dull yellow. Wings tinged yellow. 



Length of female specimen 13 mm., the type has the abdonen 

 broken off and gummed on to the label, it appears ab,)at the same 

 length. 



" Face covered with grey tomentum which becomes on the upper 

 part on cheeks near the eyes, and on subcallus yellowish brown, 

 cheeks with some brown hairs. Beard brownish with some yellow 

 hairs. Palpi narrow, almoit the same width throughout, dull 

 yellow, the first joint with long brownish hairs, which continue not 

 quite so long on the lower border of second johit, which abov^e is 

 covered with the usual short black pubescence. Antennae reddish 

 yellow, the first two joints with black pubescence, the third narrow 

 but with a very prominent short tooth, at apex it is dusky in 

 colour with hairs at the joints^ apex of toDth also with a few black 

 hairs. Forehead about five times as lon^ as it is broad, and 

 slightly narrower anteriorly, the frontal callus reddish brown, pear- 

 shaped, with a short linea' extension, not reaching the eyes. 

 Thorax brownish. .-1 hdomen apparently chestnut-brown the segmen- 

 tations lighter with traces of golden yellow hairs, which are distinct 

 on the sides and scattered on the dorsum ; under side the same. 

 Legs chestnut-brown, the tibiae yellowish, fore coxae covered with 

 grey tomentum and with pale hairs, femora with some long soft 

 pale hairs, pubescence otherwise black. 



Tabanus flaviventris, $ , Bigot. 



Mem. Soc. Zool. France, v, p. 657 (1892). 



Type $ and two others from Sibsagar, Assam. 



In the description India only is mentioned, but the spv.'cimens 

 are all labelled with the locality; the fourth specim.m included by 

 Bigot under this species does not belong to it but is a new s])jcies 

 now named Tabanus diver si frons. 



In Indian Museum coll. other females evidently of the 

 original typical series from Sibsagar. In Brit. .Mus. coll oiie male 

 and two females from Ceylon (Yerbury). one of the females is 

 marked as "not common." None of the specimens are in very 

 good condition. 



A small yellow species easily recognised b\- its yellovv al)dome;i, 

 legs and antennae, clear wings and {parallel forehead with a small 

 indistinct yellow frontal callns. Length tyjK' \\ nun : others 

 11—14 mm.
