row reddish-brown basal stripe ; with two black bristles at end. 

 Thoracic bristles black; middle scapular as strong as lateral 

 ones ; one anterior supra-alar ; pteropleural a little weaker than 

 sternopleural. Squamulse dirty whitish; halteres whitish. 



Abdomen with a thin, cylindrical basal stalk and with an 

 oval terminal club; punctate and pubescent like back of meso- 

 notum, but long and erect whitish hairs at base on sides; seg- 

 mentation distinct; third segment with long black cilia. First 

 and second segments black with yellowish hind border, that 

 of second being broader and not extending to sides; third 

 segment entirely black; fourth and fifth segments long, the 

 latter longer than the former, black, with a broad reddish yellow 

 middle patch, which has on the middle a narrow, black longitud- 

 inal stripe, ending before hind border of last segment. Oval 

 patches of fifth segment less distinct, shining but not differently 

 colored. Venter very concave, with yellowish membrane and 

 with black sternites, basal one clothed with long whitish hairs; 

 genitalia reddish. Coxa? reddish brown ; femora black in the 

 middle, yellowish at base, reddish at end; tibiae reddish, more 

 or less darkened, the posterior ones being more broadly black- 

 ish; tarsi reddish, with pale base; spur of middle tibia? long 

 and black. 



Wings (Plate II, fig. 5) proportionally short, shining and 

 iridescent. Veins black, second straight, third less curved 

 downward at end and parallel with the last portion of fourth, 

 which is less curved at base; small cross vein a little beyond 

 middle of discoidal cell ; second basal cell broad, but about twice 

 as long as broad ; prolongation of anal cell very long ; no super- 

 numerary lobe. Pattern very simple and less developed, con- 

 sisting only of a narrow, dark, costal border, in the middle not 

 extending beyond second longitudinal vein, while at end it is a 

 little dilated below third vein but without being spotlike. First 

 basal cell infuscated above second; hind cross vein not infus- 

 cated; anal stripe quite wanting, only a grayish shade being 

 present at end of the point of anal cell, into the terminal outer 

 angle of the axillary cell. Costal cells a little infuscated ; stigma 

 darker. 



Note. — The description of the Javanese M. conopoides de 

 Meijere is very much like that of the present species, which, 

 however, is different in having well-developed lower orbital 

 bristles and in having nonspinose front femora.
