EUMERUS. 113 
This species is nearly allied to the recently described L. bequaertz, 
Herné-Bazin (1913), and very probably ‘corresponds to the un- 
named specimens recorded from Basoko by the author on p. 78 of 
the work in question; it differs in being smaller, in having much 
broader yellow abdominal spots, which besides are of a triangular 
shape, and in the infuseated cross-veins.

3. Length of the body 7 mm. 
This species is distinguished from any of its congeners at present 
known, owing to the presence of a very strong spine near the base 
of the hind femora. 
Head black; vertical triangle very long and narrow, shining, 
pollinose only in the anterior angle, clothed with erect erey hairs ; 
ocelli formine an equilateral triangle, which, however, extends £ far 
forwards and is distant from the vertex ; occiput prominent above, 
white pollinose near the eyes ; frontal triangle and face clothed 
with very dense white pollen and minute white pubescence; eyes 
quite bare except for the presence of a few hairs below, in contact 
for a distance shorter than the frontal triangle; antennz short,

dark yellowish, the third joint small, subquadrate, with a black 
bare arista at the base. Thorax shining eneous, punctate, with 
very short grey pubescence, which is a little longer on the pleure ; 
on the middle of the back there are two distant parallel stripes of 
white pollen extending beyond the suture, but not reaching the

black and bears short tubercles : ; in the middle it is almost as bare 
as the thorax. Squamule pure white and white-fringed; halteres 
yellowish. Abdomen very narrow, with parallel sides, narrower 
than the thorax, of a black colour with eneous and dark purplish 
reflexions; second to fourth segments with equal pairs of broad 
lunule, not very oblique and approaching one another in the
