274 Miss G. Rlcardo on (he 



Coll., and two females in Mr. Frencli's Coll., both from 

 Endeavour River, Queensland. Walker's type was described 

 from an unknown locality, the other female from New 

 Holland, Both specimens from Endeavour River have been 

 compared with the Macquart type in the Paris Museum 

 by myself and Monsieur SnrcouE. I consider them also 

 identical with Walker's type. 



A medium-sized brownish species with indistinct median 

 ^rey spots on the abdomen. Forehead narrow, antennae and 

 le^s reddish. 



Length 12|-15 mm. 



Face covered with greyish tomentum, and with some 

 few pale hairs. Beard yellowish. Palpi yellow Avith black 

 l^ubescence, stout, ending in a fairly fine point. Antenn(B 

 reddish yellow, dusky at apex, the first two joints with black 

 hairs, the third rather broad at the base with a distinct 

 angle. Forehead narrow, about eight times as long as it is 

 l)road anteriorly, a third narrower anteriorly than at vertex ; 

 the frontal callus chocolate-brown, oblong, taking up nearly 

 the whole space between the eyes, with a narrow lineal 

 extension. Eyes bare. Thorax blackish with grey tomen- 

 tum. Scutellinn appearing reddish, being denuded. Abdomen 

 tawny, with grey tomentose median spots not forming a 

 continuous stripe, on all the segments, commencing from 

 the second one, on which the spot is largest, being triangular, 

 pubescence on dorsum 1)lack ; underside the same colour 

 with pale segmentations. Legs with femora reddish, the 

 tibise chamois-leather ■with black pubescence, tarsi blackish 

 at apex. Wings clear, stigma and veins yellow, no 

 appendix. 



Walker's type is in poor condition, but appears to be 

 identical with the specimens I compared with type in the 

 Paris Museum.

The female type of Tabanus succiirvus, Walker, from 

 Macassar, Celebes, the same locality as that of Tabanus 

 factiosus, appears to me identical with this latter species, 

 though a dark-coloured specimen, the tibise being only dull 

 reddish at base (not yellowish), and the spots on the abdo- 

 men not visible, probably owing to denudation ; the beard
