Smicromyrme (Trogaspidia) bugalana (Bischoff). 



Numerous spécimens of this species before us belong to the form 

 which Bischoff calls kibomboana and of which we hâve also seen the 

 type. We hâve not seen the typical form, but as the différence is only 

 in the density of the wing coloration it seems probable that both are 

 morphologically alike. The type of Bischoff's propodealiformis, 

 however, shows such a distinct clypeal structure that we must give 

 it, spécifie rank. 



We hâve one pair from Béni, taken in copula (J. Bequaert), of 

 which the maie shows no structural différence from the maies of 

 kibomboana, but the first and third tergites are entirely black and the 

 disk of the wings is somewhat paler. We could consider it a variety 

 of bugalana, but do not deem it necessary to distinguish it with a 

 name. As the female of bugalana was not known with certainty, we 

 subjoin a short description of both sexes of this pair. 



Maie. — Black; morocco red on the second abdominal segment; 

 calcaria pale. Covered with conspicuous, silky white setae, dense on 

 the face, clypeus, and mesopleurae; forming thin apical fringes on 

 ail but the last abdominal segment; a pubescent band on the prono- 

 tum. Wings stained brewn, with a strong violaceous reflection. 



Length : about 15 mm. 



Head transverse, strongly narrowed behind the eyes, irregularly 

 punctured above. Antennal grooves margined above. Clypeus with 

 a densely hirsute superior area, the oblique latéral arms of which 

 enclose a shallow médian basin on the impunctate disk; anterior 

 margin produced into a short, transverse, oblique lobe, with a basai 

 row of set je on each side, forming a blunt, raised tooth. Second seg- 

 ment of flagellum subequal to the third. Dorsum coarsely punctured; 

 mesonotum with a médian, raised, impunctate line; parapsidal fur- 

 rows distinct posteriorly; between them and the tegulse an additional 

 raised line. Tegulse smooth and polished, with punctures only along 

 the anterior and inner edges, around the outer edges finely striolate. 

 The scutellum with a médian raised carina somewhat compressed, 

 but little elevated posteriorly, truncate behind. Mesopleurse with an 

 oblique, médian dépression; a short, oblique carina in front of the
