KL'MEKrs. 113 



This species is nearly allied to the recently described E. bequaerfi, 

 Herne-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 infuscated cross-veins.

d" . 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 grey hairs ; 

 ocelli forming 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; antenna? short,

dark yellowish, the third joint small, subquadrate, with a black 

 bare arista at the base. Thorax shining aeneous, punctate, with 

 verv short grey pubescence, which is a little longer on the pleurae ; 

 on the middle of the back there are two distant parallel stripes of 

 white pollen extending beyond the suture, but not reaching the 

 scutellmn. Scutellum long, with sharp hind border, which is 

 black and bears short tubercles ; in the middle it is almost as bare 

 as the thorax. Squaniulse pure white and white-fringed ; halteres 

 yellowish. Abdomen very narrow, with parallel sides, narrower 

 than the thorax, of a black colour with aeneous and dark purplish 

 reflexions ; second to fourth segments with equal pairs of broad 

 lunulse, not very oblique and approaching one another in the 

 middle ; pubescence very short, except at the base ; genitalia 

 rounded, not bilobate, concealed. Legs black, with short pale
