and uervures are fulvous. The base of the basal segment of the 

 abdomen and its sides are covered with fulvous pubescence ; its 

 apex and the apex of the second are fringed with similarly coloured 

 hair : the hair on the rest of the segment and the ventral scopa 

 deep black. Teguloe rufous. 



The apex of tbe clypeus is transverse in the middle and has the 

 sides rounded ; the central part has an irregular margin, almost 

 toothed on the outer side ; the hinder ocelli are separated from each 

 other by twice the distance they are from the eyes. 



Comes near to M. dimidiata Sm.

This species closely resembles one from Borneo which is also 

 undescribed. They both agree in being large, in having the pubes- 

 cence black, except on the apex of the abdomen (where it is pale) 

 and the scopa (which is bright red). The differences between the 

 two may be expressed thus : — 



Head and thorax closely and strongly punctured ; the apical 

 segment of the abdomen clothed with pale pubescence ; the 

 mesonotum not furrowed laterally. Length 21 mm. frederici. 



Head and thorax sparsely punctured ; the apical two seg- 

 ments of the abdomen clothed with pale pubescence ; the 

 mesonotum with a wide, deep furrow on either side. Length 

 23-24 mm hicanaliculata. 



Head strongly and closely punctured ; the face is not so strongly 

 or regularly punctured and in the middle is shagreened only ; it is 

 distinctly separated from the face. The inner part of the man- 

 dibles is irregularly punctured ; the outer side has the punctures 

 smaller and more widely separated ; the apical tooth is bkmtly 

 triangular ; the subapical is a bluntly rounded small tubercle. 

 Mesonotum with the scutellum closely, uniformly, and strongly 

 punctured ; the postscutellum is closely and minutely punctured : 

 the basal area of the median segment is smooth and shining ; the 

 rest of it is closely and minutely punctured ; the base of the seg- 

 ment is fringed with long white hair. Pro- and mesopleurse closely 

 punctured, the metapleura coarsely shagreened. Legs deep black, 

 with deep black pubescence ; the pubescence on the underside of 

 the basal joint of the tarsi is bright rufous ; the calcaria dull 

 red, almost brown. Wings hyaline, slightly suffused with fulvous 

 tints ; the nervures are fuscous black, the stigma darker coloured. 

 Abdomen black ; the back almost bare to the last segment, which is 

 thickly covered with greyish-white pubescence ; the segments are 

 sparsely punctured at the base and apex ; the scopa is bright rufous ; 

 the basal ventral segment is for the greater part reddish brown.
