Ressembles very much M. sycorax, and might be easily mistaken 
for it; the abdomen however is more pyriforme, the mesonotum is 
black, the ventral carina of the first joint is not sharply dentate, and 
the ridge on the ventral part of the second joint does not end in a tooth; 
the punctures on the second segment are much more elongate, and the 
intervals much raised and sub-linear. 
Male. — Black, clothed with black and grey hairs and with white 
abdominal patches; head shagreened, anterior and posterior part 
clothed with dense, greyish white hairs; prothorax also clothed with 
greyish hairs, mesothorax with five longitudinal grooves, scutellum 
produced in a thick, short trıangle, metathorax wıth a broad median 
groove, carinate on each side and reaching to about half the length, 
and a supra-lateral, sub-diagonal carina coalescing at about mid- 
way with the outer margin, which is also very sharp; abdomen sessile, 
first joint not banded, second one covered with a withe patch, leaving 
a diamond-shaped space denuded in the centre, the other joints, except 
the apical one, have a lateral apical band; underneath the five ultimate 
joints have a lateral fringe of sparse, greyish hairs, and the ventral 
carina of the first joint is short, truncate at both ends, and not incised; 
wings subviolaceous. The prothorax and mesothorax are deeply and 
closely punctured, and the metathorax closely foveate, the scutellum 
is thickly fringed with long, greyish hairs; the abdominal segments 
have shallow, spaced punctures. Length 13—15!/, mm. 
* As closely allied to M. medon, Sm., as the female is to M. sycorax, 
Both sexes have been sent to the museum by Colonel J. H. Bowker as 
having been caught in copula. I have some doubts, however, as to 
the identity of both sexes, because they are so differently marked. In 
M. sycorax (? guineensis) the two sexes, which I have several times 
bred from the mud nests of Pelopoeus spirifex, have similar markings. 
It is very singular that the female, which is so closely allied to M. sy- 
corax that it is diffieult to distiguish the two, should differ so much 
from the male.

„Male. — Black, with the thorax ferruginous red; second ab- 
dominal segment with a narrow, apical, seemingly not interrupted 
silvery white pubescent band, third segment with a very broad band 
of the same textour and colour covering nearly the whole surface, 
but somewhat broadly interrupted longitudinally in the centre; wings 
deep fuscous or black but with the basal part hyaline for about one- 
fourth of the longth and a small space at the apex also hyaline, in the 
first radial cell is a median, small. somewhat rounded transparent patch; 
body covered with a greyish white pubescence and erect hairs inter- 
mingled with black ones which on the upper side are more numerous 
than the white. — Head closely and irregularly scrobieulate, smaller 
than the thorax, but equal in width to the anterior part ofthe pronotum,
