" ^ . 1"9 mm. Smaller and a little paler than Leimbachi, but not 

 so pale as Oscaris-excensurae. It is distinguished from both by the 

 profile being subtruncate in front of the clypeus, which gives it a 

 false appearance of a Bondroitia. In profile, the mandibles extend 

 very little beyond the clypeus. The frontal carinse behind form a 

 strong curve with their anterior lobes, which are situated on the sub- 

 truncate portion. The eyes, placed within the anterior third of the 

 head, are fairly large but almost unpigmented. The abdomen has 

 some brown bands, not very distinct. The shape of the petiole and 

 thorax, like the sculpture and other characters, is identical with that 

 of Leimbachi, but the head is slightly' narrower. The eyes are com- 

 posed of about 15-20 facets."

" ^ . T4-T6 mm. Reddish yellow or yellow, the abdomen more or 

 less brownish, the 1st segment above yellow, brownish at the sides 

 and near the posterior margin. Masticatory margin of the mandibles 

 reddish brown, the last four joints of the flagellum and also the hind 

 margin of the head slightly brownish. Very sparsely pilose, with 

 fairly long erect hairs. Very smooth and shining, sparsely punctured 

 with piligerous punctures, the cheeks in front longitudinally striate, 

 the frontal carinae somewhat striate, the meso-pleura below finely 

 and shallowly reticulate. Mandibles quadridentate. The head very 

 distinctly longer than wide. The clypeus has a rounded anterior 

 margin ; no median groove, teeth, or carinae ; but the posterior lateral 

 margins, between the antennal sockets, somewhat projecting. Antennae 

 12-jointed; the apex of the scape is nearer to the posterior angles of 

 the head than to the eyes ; the 2nd-8th joints of the flagellum very 

 small, much wider than long. The 1st joint of the club as wide as 

 long or a little wider, the second a little wider than long, the last 

 joint nearly twice as long as the first and second together. The eyes 

 are rather small, placed in front of the middle of the head. The 

 thorax is constricted at the meso-epinotal suture ; the dorsum of the 

 epinotum passes arcuately into the declivity, which is but half as long. 

 The 2nd joint of the petiole is somewhat wider than long, distinctly 

 lower than the 1st joint, and not wider, or hardly wider, than the 1st. 



This species stands close to M. disjjar. In this species the head is
