68 Cameron, Hymenoptera Orientalia. 



rufous ; coarsely punctured, covered with longish and 

 white and fuscous hairs ; behind the eyes less than their 

 length ; narrowed and rounded. Antennal scape covered 

 with long pale hairs, not grooved ; the flagellum obscure 

 fuscous beneath ; covered with an indistinct microscopic 

 down ; the third joint nearly twice the length of the 

 fourth. Mandibles grooved on the outer side. Thorax 

 a very little dilated gradually towards the apex ; the pro- 

 notum coarsely shagreened ; mesonotum coarsely rugosely 

 punctured ; median segment at the apex with an abruptly 

 oblique slope ; the propleurse obscurely, the metapleurse 

 coarsely rugosely reticulated, its outer edge spinose ; the 

 mesopleurse shining, a little excavated, smooth, shining, 

 and glabrous. Legs thickly haired ; the spines thick, 

 pale and black on the tibiae, rufous on the tarsi. Basal 

 abdominal segment gradually dilated towards the apex, 

 not distinctly separated from the second ; on the latter 

 are two oval whitish fulvous marks near the base ; the 

 third and fourth have two marks of the same colour; 

 those on the latter the smaller ; the apical is fringed 

 laterally with pale long hairs, and is closely aciculated 

 or shagreened. The basal ventral segment is obscure 

 rufous ; the keel in the middle has a longer and a shorter 

 blunt tooth ; the second segment has widely scattered 

 punctures ; the others are finely transversely striated at 

 the base ; the apex with scattered punctures and covered 

 with long pale fulvous hairs. 



Resembles closely M. aulica Sm., in coloration, but 

 wants the large spot of silvery pubescence on the 

 vertex, and otherwise is easily known from M. aulica by 

 having the pronotum at the base transverse, with the 

 sides acute ; while M. aulica has the sides broadly 

 narrowed and the base not transverse. In one of my 

 examples of M. aulica there are only four white spots 

 on the abdomen.
