Epuraea ornatula new species. 



Oblong, slightly elongate, somewhat convex, rufo-testaceous, sparsely 

 clothed with minute yellowish pubescence, scarcely shining; head closely but 

 somewhat indistinctly punctured, front convex with distinct impressions. An- 

 tennas rufo-testaceous, club piceous, third joint twice as long as wide, one 

 third longer than the fourth, fourth and fifth of equal length, six, seven and 

 eight shorter. Thorax one half wider than long, narrowed in front, sides 

 moderately arcuate from apex to one third from the base, thence obliquely 

 narrowed to the posterior angles which are obtuse, distinct, but finely rounded. 

 There is a faint sinuation before the angulations at one third and before the 

 posterior angles. The sides of the prothorax are widely explanate with the 

 margins narrowly but strongly reflexed, especially at and before the middle; 

 the anterior margin is strongly emarginate and the angles prominent though 

 obtuse and rounded ; the punctuation is indistinct. The elytra are scarcely 

 broader than the prothorax, and twice as long, scarcely wider at the middle, 

 thence narrowed to the apices which are broadly rounded, side margins rather 

 widely reflexed ; punctures rather coarse, close and distinct throughout. Un- 

 derside as coarsely and closely but not so distinctly punctured. Intercoxal 

 process of the abdomen narrow and triangularly acute. Length 2.25 mm., 

 width 1 mm. (one male). 



Male. — Additional abdominal segment, middle tibiae faintly sinuate on the 

 inner edge and strongly dilated at tip. 



This species seems distinct from E. boreela Zettr. its closest ally, 

 by its smaller size, color and form. 



REVIEW. 



A Revision of the Vespida of the Belgian Congo based on the Collection of 

 the American Museum Congo Expedition, with a List of Ethiopian Di- 

 plopterous Wasps. By J. Bequaert. Bulletin of the Amer. Mus. of Nat. 

 History, 1918, 39: 1-384, vi pi. (2 col.), illust. 



Abundantly qualified, by reason of several years' field experience 

 in the Belgian Congo and other parts of Africa, a portion of that 

 time in association with Messrs. Lang and Chapin in the expedition 

 referred to in the title, as well as by an intimate knowledge of the 

 diplopterous wasps, Dr. Joseph Bequaert has published a memoir, 

 which, not by reason of its subject matter or its comprehensiveness, 

 but rather by the masterly way in which that subject matter is dealt 

 with, and by the keen taxonomic perception and sound judgment 

 which that treatment manifests, raises its author indubitably to the 

 very front rank of this world hymenopterists. Indeed, it sets a taxo-
