Haematopota lunulata (Macq.) v. d. Wulp, Sum, Exp. 

 Tab. I, f. 14. 



Haematopota sp.? 



All the specimens before me have the design on the wings like 

 the above-quoted figure of Mr. v. d. Wulp ; but some of them have the 

 antennae reddish, except the latter part of the 3'''^ Joint, which is black; 

 and, at the same time, two whitish rings on the bind tibiae; the other 

 group of specimens has altogether black antennae and only o n e white 

 ring near the base of the bind tibiae. Neither of them agrees entirely 

 with Macquart's description. 



Chrysops signifer Walk. J. Pr. Lin. Soc V, 277 (Bätchian). 

 I found the species thus determined and the specimens ( $ Q ) agree 

 with the description. They vary in size very much. About Chr. 

 unizonatus Eond. I took the following note when I saw the type in 

 Genoa, a single specimen: „very like signifer Wk., only face altogether 

 yellow; first abdominal segment yellow. May be only a paler variety." 



Chrysops dispar (Fab.) Wied. A. Z. I, 196. I believe C. 

 impar Rond. Ann. M. C. Gen. VII, 460, to be the same as dispar; 

 I have Seen the types. 



Tahanus. There are about a dozen species in the coUection, 

 most of which it would hopeless to recognise among the 120 described 

 species of this genus from South-Eastern Asia, as they show no striking 

 distinctive characters. Five of the species belong in the group with a 

 very narrow (9) front, and a narrow frontal callus, coalescing with a 

 linear Prolongation above, a group abundantly represented in the 

 Austro-Malayan Archipelago. Three species have the front and callus 

 of the ordinary structure, and resemble, in their coloring, some european 

 and N. American species. The two following species • deserve a 

 special mention, 



Tahanus van der Wulpi n. sp. $9. 



Syn. Tabanus pictipennis v. d. Wulp, Tijdschr. v. Ent. XI, 100, 

 Tab. III, f. 1, 2 (Celebes). 



Mr. v. d. Wulp 's figure of this species is unmistakable ; some dis- 

 crepancies in the description are due to the fact, that he had a teneral, 

 and therefore not fully colored individual. I owe this explanation to 

 himself, after he had kindly compared one of my specimens with bis 

 own type. The name pictipennis being preocupied by Macquart
