central rariiia; straight and tlie lateral more slender and sub- 

 oblique ; postscutelhnn large and deplanate with a small central 

 fovea at its base and a large, deeply impressed one on either side 

 extending to its apex. Ahdomoi. glabrous and nitidulous, black, 

 with a distinct plumbeous reflection ; basal segments nude, the 

 apical with white pilosity ; ventral segments plumbeous, with 

 their apices white ; hypopygiun) punctate and cultriform ; terebra 

 almost as' long as body (12 millim.). Legs densely white-pilose, 

 black, with the front femora and tibiae anteriorly dull testaceous ; 

 coxae and femora somewhat strongly punctate. Wings infuscate 

 hyaline, and subinfumate below the stigma and at the apex. 



Length VA millim. 



The S differs little from Cameron's description of the $ , given 

 above. It has the flagellar joints apically nodulose; the vertex 

 broad, as broad as the thorax ; the eyes are prominent and render 

 the head broader than the thorax; the palpi fulvous; the scu- 

 tellum is punctate throughout with its basal fovea strigose ; the 

 metanotum is fully areated with only the glabrous areola confluent 

 with the petiolar area, the costulie are emitted but shortly beyond 

 the transverse basal area and the lar^e spiracles lie in a glabrous 

 space ; the basal segments are laterally pilose with the spiracles 

 of the first slightly before its centre ; the genital organs are large, 

 red and exserted ; the wings have the whole of tlieir apices and 

 a semifascia below and beyond the stigma somewhat strongly 

 piceous. 



Length 11 millim.

Type iu the British Museum. 



The 2 ^^as described from Eothuey's collection and captured 

 in the Khasi Hills of Assam ; I have seen the type in the British 

 Museum and am sure it is congeneric with the same author's 

 Siphiniedia iridicolor, of which the type is also in the same 

 Museum, from Borneo ; the only distinctions 1 can trace 

 between these two specimens are the broader head of the latter, 

 in which also the second recurrent nerviire of the fore M'iugs 

 is received beyond, and not at (as in M. nigricans), the sub- 

 marginal nervure. 



The c? is here described for the first time from an example 

 from Pen an 2:. 



2. Macrogaster varipes, Cam. 



Macrof/aster varipes, Cameron,* Mauch. Mein. 1899, p. 19() ($). 



A black species with the head and all the abdominal segments 

 white-marked, and the flagellum with a broad band of the same 

 colour. Head black ; the strongly punctate and sparsely white- 

 pilose face and cl3'peus, and the frontal orbits (the outer narrowly 

 above and broadly below) stramineous, with a slender black line
