GERTRUDE RICARDO. DIPTEREN II. 4OI 



blackish hairs on the first two joints, the third joint slender, not so wide at base. Eyes with 

 the large facets not very large or distinctly divided from the small facets on lower part of 

 eye. Abdomen on underside with some few black hairs. 



24. Tabanus ceylonicus Schiner. 



Novara Reise Dipt. p. 93 (1S68). Ricardo, Records Indian Muséum, IV, N°. VI, p. 223 (191 1). 



Prof. DE MEIJERE sent me two spécimens out of a séries of spécimens from Etna Bay 

 and Merauke, identifying them as Tabanus miniums v. d. Wulp, which is a synonym of 

 Tabanus simplissimus Wlk. Thèse spécimens appear to me to be more properly Tabanus 

 ceylonicus, the palpi being dark, and the beards blackish, but the différences between the 

 two species [simplissimus and ceylonicus) are very small as noted in the Indian Records 

 paper. Xeither species has been recorded before farther east than Sumatra. 



25. Tabanus papouinus, çf, Walker. 



Proc. Linn. Soc. London, VIII, p. 108 (1865). Osten Sacken, Ami. Mus. Civ. Genova, XVI, 

 p. 418 (1S82). 



The type is a maie, very nearly allied to Tabanus breviusculus Wlk. distinguished as 

 stated by WALKER by the narrow border of small facets of eyes reaching the vertex. The 

 abdomen is différent in colouring being a dull yellowish with some grey tomentum at base, 

 then brown with pale segmentations, the pubescence black, on the segmentations yellowish ; 

 underside similar. Length 9 mm. 



26. Tabanus breviusculus, çf, Walker. 



Proc. Linn. Soc. VIII, p. 109 (1865). 



Type (maie) from New Guinea in Brit. Mus. Coll. and a séries of maies and females, from 

 Heuvel Bivak (9), Alkmaar {çf ), Bivak Island (cf ), Etna Bay (Q) in Prof, de Meijere's Coll. 



The maies from Prof. DE Meijere's Coll. are identical with the type, though the legs 

 in the type are darker, being more uniformly reddish brown, the femora and coxae not so 

 yellow. WALKER distinguishes this species from his other species Tabanus papouinus, likewise a 

 maie, by the absence of a narrow border of small facets reaching to the hind part of head, 

 to vertex, the two maies are otherwise rather nearly allied. 



The following description is based in the fresh spécimens. 



A small yellow species, abdomen at extrême apex, darker. Antennae yellow. Legs 

 yellowish and brown in colour. Forehead nearly parallel. 



Length maies 8 — 9 mm., females 5 — 6 mm. 



Female. Face covered with reddish yellow tomentum and with a few pale brown hairs 

 on the cheeks. Palpi same colour with black pubescence, very narrow, ending in a point. 

 Beard scanty, brownish yellow. Antennae narrow, reddish yellow, black at apex, the first two 

 joints with black pubescence, tooth small but distinct on third joint. Forehead with yellowish 

 brown tomentum, almost parallel, about five times as long as it is broad, the frontal callus 

 reddish brown shining, taking up almost the whole of the space for two thirds of the length, 

 in some spécimens ending in a point, often almost the same width throughout. Thorax and
