388 Miss G. Ricarclo on the 



giving redescriptions of them, in the hope that they may- 

 prove o£ some service to workers in Australia and enable 

 them to name new species with more certainty ; there must 

 be a great number of such species in the newer districts of 

 Australia, such as Nortliern Queensland. 



For the classification of groups see my paper on the 

 Tabanus species of the Oriental Region in * Indian Records/ 

 iv. no. vi. (1911). The original pagination is used for 

 Macquart's Dipt. Exot. Nomenclature of colours is taken 

 in many instances from Ridgway's work on Colour Standards 

 (1912). Where the eyes are not mentioned, they are bare 

 and devoid of j)ubcscence. 



Group IV. 



Forehead with no callus. 

 Tabanus nemotuherculatus, ? , sp. n. 



Type (female) in Mr. Froggatt's Coll. from Cape York, 

 Queensland, 30. 2. (1906), and another female from 

 S. Queensland {Dr. T, L. Bancroft), 1908, in Brit. Mus. 

 Coll. 



This type is not in very good condition, but may easily 

 be recognized by the shading on veins of wings and by the 

 absence of any frontal callus on forehead. Abdomen nar- 

 row, obscurely ferruginous. Anteunse and legs the same 

 colour. Palpi short and stout. 



Length 10 mm. 



Face and forehead honey-yellow, the former with some 

 gi'cyish tomentum. Palpi a shade darker in colour, almost 

 the same width throughout, ending in an obtuse point. 

 Antennae ferruginous, slender, with a very slight angle or 

 tooth. Forehead parallel or almost wider anteriorly, about 

 four times as long as it is broad anteriorly. Thorax darker 

 than abdomen, covei'cd with some greyish tomentum. 

 5'c2^/e//?/m is identical. Abdomen (denuded) dull ferruginous. 

 Legs same colour, a little darker on tarsi. Wings grey, fore 

 border yellowish brown, and every longitudinal vein shaded 

 brown ; short appendix present. 



The other female has the wings almost clear. Abdomen 

 covered with greyish tomentum and with short yellowish 

 hairs intermixed with black ones. 



Tabanus nemopunctatus, ? , sp. n. 



Type (female) from Dunk Island, Queensland [Bunfield), 

 15. 1. 1903, in Mr. Froggatt's Coll.
