from the Indo-Malayan region. In Morley's key it will run to M. 

 instigator Sm. or to M. tridentafa Cam. which he considers synony- 

 mous. From Tosquinet's very lengthy description (Mem. Soc. ent. 

 Belg. 1903, 10, p. 97) of M. instigator it differs in the sculpture of 

 the face, form of clypeus, and more slender abdominal petiole. From 

 M. tridentata (Proc. Zool. soc. London, 1901, 1, p. 230) it differs in 

 the sculpture of the face, propodeum, and metapleurafe, dark scutel- 

 lum, etc.

9. Length 11 mm. Dark metallic blue; antennae black with 

 joints 11-16 white (apical joints broken off) front and middle tibiae fus- 

 cous, their tarsi brownish yellow; hind coxae and femora ferruginous, 

 their trochanters black, their tibiae black with a broad, indistinctly 

 defined, pale brown annulus near base, their tarsi pale testaceous. 

 Wings hyaline with a fuscous band, wider behind, including the basal 

 vein and transverse median nervure, and a second band, fading out 

 posteriorly which extends over the basal half of the radial cell; veins 

 black, stigma pale at base. Head nearly twice as wide as thick, 

 sharply narrowed behind the eyes; ocelli in a nearly equilateral tri- 

 angle, the posterior pair about half farther from the eye-margin than 

 from one another; face broadly protuberant below the antennae, 

 closely punctate; interantennal keel prominent; antennae slender, 

 the basal flagellar joints five or six times as long as thick, the flagellum 

 hairy, especially beyond the first few joints; mandibles without teeth; 

 front and vertex highly polished almost impunctate except at the 

 sides below the ocelli; cheeks and malar space irregularly vertically 

 striate through the coalescence of rows of elongated punctures ; malar 

 space half as long as the first flagellar joint. Mesonotum with weakly 

 impressed parapsidal furrows; densely punctate with an area on each 

 side that is sparsely punctate. Scuteilum convex, rugosely punctate 

 with a small median smooth depression on its apical half. Propodeum 

 rather evenly convex above; coarsely rugose-punctate; areolated; 

 median areas not separated from each other; basal and apical lateral 

 areas completely defined; pleural space defined by. a carina below it; 

 spiracles linear. Propleura coarsely punctate above, smooth below; 

 mesopleura coarsely punctate, confluently so near the middle coxa; 

 metapleura rugose. Abdomen subpetiolate, the first segment slightly 

 longer than the propodeum and scuteilum together, its base one fourth
