vered with 14 to 16 fine, irregular, longitudinal wrinkles which stop 

 before reaching the middle; its apical two-thirds smooth. 



Habitat : Belgian Congo, one female, Uele District (De Greef). 



Holotype : Congo Muséum, Tervueren. 



This species belongs in the group of 5. (7\) trigonophora (Bischoff). 

 Its closest relative appears to be S. (T.) serenjeana (Bischoff) from 

 which it differs in the sculpture of the pygidial area, the much finer 

 sculpture of the second tergite, the much abbreviated latéral spots 

 of pubescence on the third tergite, and the color of the thorax which 

 is red on the dorsum only. 



Smicromyrme (Trogaspidia) lukugensis, new species. 



Maie. — Black; except the abdomen which is orange rufous; the 

 under side of the first segment black. Calcaria white. Erect pubes- 

 cence of head, thorax, and legs mostly whitish and partly black; that 

 on the abdomen coppery orange. In addition there is more or less 

 dense, appressed, tomentose, slightly yellowish white pubescence 

 forming spots and bands on head and thorax as follows : on the face 

 between the eyes and clypeus; above the antennas and sparsely on 

 the lower temples; the posterior margin of the pronotum and a very 

 dense patch on the excavated lower portion of the mesopleura;; entire 

 dorsal surface of the propodeum. The tergites hâve very fine, appres- 

 sed, orange pubescence, becoming denser laterally and absent in 

 the middle; scarcely in évidence on either the first or last. Wings 

 uniformly brown, with somewhat of a violaceous reflection. 



Length : about 14 mm. 



Head seen from above much broader than long; the occiput but 

 moderately extended behind the eyes; its sides strongly convergent 

 and rounded posteriorly; its posterior margin broadly emarginate; 

 its surface with strong but well separated punctures, with polished 

 interstices; below the ocelli the punctures much denser. Ocelli form- 

 ing an isosceles triangle, the base of which is anterior to the post- 

 ocular line. Antennal groove strongly margined, the carina bent 

 almost into the shape of an interrogation mark. Clypeus with an 

 anterior, raised, roughly triangular portion, the point of which ends
