An. Indiensis, Theobald (Monog. I, p. 145). 



= An. jiiumiger, Donitz, Insect. Borse, January, 1901. 

 (Specimens of this supposed new species proved to be partly 

 examples of An. sinensis and partly An. barbirostris. 



Wing with two small ferruginous spots on the black costa, oue 

 sub-apical, the other a little in front of the cross-veins ; the rest 

 of the wing rather dark, especially towards the tip, the fringe of 

 which is, however, more or less yellow, though it is elsewhere 

 entirely black, or with some more or less pale patches at the 

 longitudinal junctions. There are never any white basal dots on 

 the costa. Tarsi with pale apical bands throughout, though often 

 barely perceptible on fore and middle legs ; the last joints gener- 

 ally rather paler at tip. Thorax with a grey bloom, laterally 

 red-brown with scattered golden scales. Abdomen black, nude, 

 with scanty brownish-yellow hairs, a denser fringe of these on 

 the hinder borders of the segments giving an indistinct appearance 

 of banding. 



Head black with the exception of a white frontal tuft projecting 

 between the roots of the antennae, which are black, with pale, downy 

 tomentum between the scanty black verticils, a few of the fork-ceUs of 

 nape are whitish. Palpi very shaggy, equalling the proboscis in length, 

 with the tips yellowish and the articulations between the next two joints 

 minutely banded whitish. Halteres fuscous. Legs long and slender, 

 yellowish -brown, deepening on the tarsi, the three or four upper joints 

 of which have conspicuous distal ochreous bands, the last joints being all 

 yellow. 



In view of the incompleteness of Wiedemann's description and 

 the absence of actual specimens from China, it is by no means 

 surprising that this species should have been repeatedly re- 

 described. It is impossible to identify the annularis form by its 

 original description, as no mention is made of the number of 

 costal spots, and the figures and descriptions of the Italian form 

 leave one in entire doubt as to the position of the transverse 

 veins. I have not seen the Indiensis form, as the single specimen 

 from which it is described by Mr. Theobald was a loan from a 

 private collection, but it does not appear to differ much from the
