abdominal segment with a slightly flavescent white patch on each 

 side, second segment with a similar apical patch placed at equal 

 distance from the centre and the outer side, third segment with a 

 lateral patch more elongate than the one above it and reaching 

 nearly the outer angle but not quite in a line with the patch on the 

 basal segment ; head very broadly foveate, truncate behind, a little 

 attenuate in front, slightly ampliated laterally behind the eyes which 

 are not very large and are placed forward, mandibles broad at apex, 

 forcipate and bluntly tri-dentate at tip ; thorax narrower than the 

 head, elongate, gradually attenuate from the anterior to the posterior 

 part, about one-fifth longer than broad, somewhat angulated laterally 

 about one-third of the length, prothorax nearly truncate, outer sides 

 very little ernarginate laterally, declivity very abrupt ; it is covered 

 with foveae with the intervals raised, sharp and wavy, but more 

 longitudinal in the anterior median part ; abdomen sessile, basal 

 segment with a sharp basal tooth on each side, as broad at apex as 

 the basal part of the second, which is a little longer than broad and 

 closely but irregularly strigillate, the basal one is more roughly 

 strigillate ; the pygidium and the under side of the abdominal 

 segments are clothed with dense greyish-white hairs ; the tibiae have 

 two series of closely set conspicuous spines., and the spurs are ivory- 

 white ; the ventral carina of the basal segment is short and sharp 

 and gradually sloping from base to apex. Length 13-13A- mm.

Probably closely allied to M. ignava, Sm., which is not represented 

 in the Museum Collection.

? . Upper part of head, antennae, thorax, tibiae and tarsi red,, 

 under side of head, abdomen, and femora black, second abdominal 

 segment with a basal median flavescent, more or less round, patch and 

 a supra-lateral one on each side, third and fourth abdominal seg- 

 ments with a slightly flavescent band ; head closely foveolate, very 

 quadrate in front owing to the genae being produced in a sharp 

 angular process, transverse on the vertex, nearly truncate behind, 

 eyes large, lateral, reaching beyond the median part of the outer sides 

 which are straight ; it is covered with a flavescent pubescence inter- 

 mingled with long black hairs ; thorax nearly straight at apex with 

 the outer angles somewhat rounded, elongate, of equal width for 

 about one-half of the length, narrower and nearly parallel from there
