at apex of second segment; fourth and fifth if divided into three equal 
areas would be cream-scaled in the first or basal and third or apical areas 
and black-brown-scaled in the second. The apical would be very slightly 
longer, owing to the tuft of cream scales at tip. Proboscis uniformly 
dark-brown-scaled, the tip being scaleless, lighter brown, and bristled. 
Prothoracie lobes dark-brown, clothed with narrow scales and bristles; 
mesothorax with broad, grey, median area, bordered by brown and with 
sparse, golden, curved, hair-like scales; a very much elongated narrow, 
dark V-mark extends from the prothoracic lobes across grey median area, 
meeting the apex of an acute triangular brown spot at posterior margin ; 
scutellum simple and sparsely covered with golden hair-scales ; metanotum 
nude, brown; halteres ocher, dark-knobbed. 
Legs quite uniform brown; femora lighter basally; tibia somewhat 
swollen apically and truncated ; metatarsi and tarsi dark-brown ; in some 
lights the last tarsi of posterior legs appear light-brown and the bases of 
all tarsal segments are lighter. 
Abdomen a uniform dark-brown, with golden hair scales; the basal 
ventral segments slightly lighter. 
Wings cream, spotted with brown as follows: Four prominent large 
brown spots on costa, beside 2 small basal and 1 at extreme apex 
on curve of wing. The 4 large ones are: First 15 times its own 
length from base of wing and occupying costa, subcosta, and Vein I 
equally ; second, which is largest, } its own length from first and oceupy- 
ing costa and subcosta equally, but on Vein I its second quarter is cream, 
much as in M. ludlowti Theob.; third spot its own length from second 
and occupying costa and Vein I equally; fourth its own length from 
third and occupying costa and Vein I. The extreme apical tiny spot 
referred to above is 5 times its own length from costal spot 4, lying 
between forks of first submarginal cell. Vein II with brown on each 
side of cross vein, its anterior fork with 2 spots lying below costal 
spots 3 and 4, respectively; its posterior fork all brown except extreme 
base and apex; Vein III with brown spot near base and very tiny spot 
near apex; Vein IV brown from opposite costal spot 1 to near mid 
eross vein, then cream, then its entire stem brown with base of forking 
cream; its anterior fork all brown except slight cream at base and apex : 
its posterior fork with long brown spot in middle; Vein V with small 
brown spot near base and at its forking; its anterior fork with 3 
long, brown spots, the middle one longest; posterior fork cream on basal, 
brown on apical half, except cream spot at junction with margin. Vein 
VI with basal half, cream except a small spot at its middle; apical half 
brown, not reaching margin. Marginal fringe brown-slate with slight 
cream near base and cream interruptions at forks of Veins TV and V 
and at apex of Vein ITT. 
$ of this species unknown.
