ADSTRO-MAliAYAN DIPTERA 409 



Hab. Mount-Singalang , Sumatra; July 1878 (Beccari). 



NB. I. Antidoxion fulvicorne Snellen v. Vollenh., Versi, en 

 Medd. K. Akad. Wetensch. 1863, f. 1-3(9) from Java, is very 

 like R.. zonatus, but differs in being a little larger ; the an- 

 tennae are comparatively longer, the thorax and abdomen have 

 more red in their coloring ; the wings have a more brownish 

 tinge, especially on the distal half; the cloud in the middle is 

 much larger ; the halteres altogether reddish. It is singular that 

 Snellen v. Yollenhoven attributes 26 joints to the antennae ; his 

 own type in Leiden (which I saw) has 34-35 joints. The num- 

 ber of joints may be differently counted, as the first and last 

 joints of the flagellum show a slight suture. 



NB. IL There is no reason to separate Antidoxion from 

 Rliachicerus. I have compared R. zonatus with an american 

 species, and have not found anything to justify the separation. 

 A species from Brazil, in the Yienna Museum ( $ , Coll. Beschke, 

 in the Winthem Collect.) is not unlike R. zonatus j, especially 

 in the structure of the antennae ; but I counted only 22 joints 

 on them. Thus we have now this genus from North- America 

 and Cuba (5 spec). South- America (one sp.), the East Indian 

 Archipelago (2 sp.) and Spain (one species, described by Loew, 

 in Beschr. Eur. Dipt. I, 248). 



STRATIOMYIDAE. 



Campeprosopa munda n. sp. J'. Thorax metalhc bluish-green ; 

 abdomen metallic-blue , 2"^ and 3'^ segments brownish-yellow , 

 with a square, metallic-blue spot on each side ; apex of the 

 wings infuscated. Long. corp. 8-9 mm. 



Head black, front narrow, almost linear; antennae black; 

 proboscis pale yellow. Thorax metallic bluish green, but little 

 shining, as it is microscopically punctate and clothed with an 

 appressed, not very dense, yellowish pubescence ; a longer and 

 more whitish pubescence on the pleurae ; a smooth , shining , 

 metallic blue or green space between the root of the wings 

 and the collare. Scutellum like the thorax in color , sculpture
