igii-J G. RiCARDO : Revision of the species of Tabanus. 157 



Tahanus vagus, type, $ , is from E. India (Saunders coll.), 

 another female from same locality and one from Java were 

 identified b}^ Walker as this species, but I find no difference in the 

 specimens from those of Tahanus alhimedius. 



Tabanus unibrosus, type, 9 , from E. India (Saunders coll.), has 

 the legs somewhat darker than usual, and the median stripe is 

 straighter and narrow. 



Tabanus prisons, type, 9 , from an unknown locality, appears 

 to be identical with T. alhimedius , but priority is not given to it 

 owing to the doubt as to localit3\ 



? Tahanus calidus, type, 9 , from Asia, but in the description a 

 query accompanies the locality ; this is presumably a specimen of 

 Tabanus alhimedius very similar to the series of specimens from 

 Ceylon. 



Aty lotus lachrymans , 9 , Bigot, from Java, appears identical 

 with the Walker species. 



Tabanus spcciosus, 9 , n. sp. 



Type rf from Travancore, 



Type 9 from India (Wroughton), and another female from 

 Tamblegum, Ceylon (Yerbury), in Brit. Mus. coll. In Indian 

 Museum coll. female from Travancore, S. India. 



A distinctly marked conspicuous species with a superficial 

 resemblance to Tabanus reducens, Wlk., from Celebes, but dis- 

 tinguished from it b}^ the presence of side spots. It is allied to 

 Tabanus rubidiis, Wied., but the conspicuous spots on the third 

 and fourth segments of abdomen with wide bases will distinguish 

 it ; on the second segment the spot is very narrow so that the 

 stripe has a much more unequal appearance; and it is larger in size. 



A black species, with three series of white spots on abdomen, 

 legs blackish with yellow tibiae, antennae red, wings almost clear. 

 Length 19 mm 



9 . Face covered with greyish white tomentum, with silvery 

 white pubescence and beard. Palpi pale 3'ellow with some black 

 pubescence, stout, ending in a short acute point. Antennae red, 

 duskier at the apices, the first two joints pale yellow with black 

 pubescence, tooth of third joint small but distinct. Subcallus same 

 colour as face. Forehead with rather darker tomentum and with 

 some white pubescence, about seven times as long as it is wide, 

 only slightl}' narrower anteriorh^, the frontal callus reddish brown, 

 large, oblong, not reaching the eyes, the short linear extension not 

 always visible. Thorax reddish brown in type, probably blackish 

 brown when not denuded, with five distinct grey tomentose stripes, 

 with yellowish white pubescence on them, sides with black hairs, 

 round the base of the wings with white ones ; breast covered 

 with grey tomentum and with white pubescence. Scut ell uni 

 same colour as thorax, with white ])ubescence at sides and on 

 posterior border. Ahdonieu blackish brown, the median stripe
