Mangesia atopogamia, sp. n, 



J . Niger ; capito, pronoto, mesouoto scutelloque rufis ; flag-cllo 



nigro ; alis fu.<co-C3eruleis. 

 Long. 17 mm. 



$ . jNIandibles very broad, with five strong teeth; clypens 

 with a distinct median carina ; antennae inserted low down, 

 close to the base of the clypeus, a tubercle above the base of 

 each antenna ; the flagellum covered with black pubescence_, 

 the first joint as broad as long, the third nearly as long as the 

 first and second combined and fully half as long again as broad, 

 the apical joint longer than the penultimate and about five 

 times as long as broad. Head punctured-rugose, subquadrate, 

 rounded at the posterior angles ; eyes separated from the 

 posterior margin of the head by a distance not exceeding their 

 own length ; ocelli in a triangle, the posterior pair about four 

 times as far from the eyes as from each other. Thorax 

 coarsely punctured, the pronotum strongly rounded ante- 

 riorly ; median segment coarsely rugose, with a median 

 longitudinal carina, the surface of the posterior truncation 

 transversely rugcse-striate. Abdomen flattened, smooth 

 and shining, the seventh segment very broadly rounded at 

 the apex. Neuration similar to that of fuscipennis, Kieff., 

 the type of Mangesia ; but the extension of the radius is 

 more distinct, and the cubitus is continued beyond the apex 

 of the second cubital cell, though broken by a white scar at 

 the junction of the first transverse cubital nervure. 



Hab. S.W. of Lake Chilwa, Nyasaland; January (^S. A. 

 Neave) . 



The head is much more quadrate than in fuscipennis and 

 less narrowed posteriorly, the petiole is shorter, being broader 

 than long, and only the median carina of the median seg- 

 ment is developed. The tarsal ungues are tridentate, as in 

 Kiefler's figure (Ann. Soc. Sci. Bruxelles, p. 201, 1911). 

 Superficially this species strongly resembles Elis atopogamia, 

 Sauss., which occurs in the same locality, the size and colour 

 being the same in both species.
