The unique maie type of this is before us and as it differs in the fol- 

 lowing structural characters from alecto, it should be ranked as a 

 distinct species. Clypeus with an anterior, transverse plate, not de- 

 pressed below the level of the disk; its anterior margin very slightly 

 concave; its antero-lateral angles a little less than right angles; its 

 sides parallel; its transverse extension much greater in proportion 

 to its length than in the case of alecto; its surface covered by a row 

 of punctulations which bear small setse; it is delimited above by a 

 very weak carinula, not reaching its sides, and above this are two or 

 three fine, transverse striolae. Mesopleurae closely, but not deeply 

 and only moderately coarsely reticulo-punctate below; just in front 

 of the middle coxae forming an oblique, crested ridge. Middle coxse 

 with a smooth and polished area, but without an elevated ridge. The 

 ridge of the scutellum with a longitudinal furrow broader than in 

 alecto, marked by less strongly raised carinse and becoming obsolète 

 toward its apex. First sternite with an anterior, truncate lobe. Seventh 

 sternite unarmed. Eight sternite with ridges somewhat shorter and 

 more erect than in alecto; the bristles of this sternit : mostly grouped 

 into two brushes, one behind each of thèse two ridges. The apical 

 membrane in the unique type is frayed at the apex, so that its shape 

 cannot be exactly determined, but it seems to be somewhat more 

 extensive than in alecto. 



Smicromyrme (Trogaspidia) prolongata (Bischoff). 



Glossotilla alberti subsp. prolongata Bischoff, 1921, Arch. f. Na- 

 turgesch., LXXXVI, Abt. A, Heft 4, p. 493 (tf). 



An additional maie spécimen of this species, from Yambata, Bel- 

 gian Congo (de GiORGi),compared with the type and with a spécimen 

 of alberti from Cameroon, substantiates Bischoff's surmise that it 

 should be regarded as distinct form, rather than a subspecies of 

 alberti (André). The disk of the clypeus bears anteriorly a broad 

 and high triangular lamella; the summit of the clypeus is on one plane 

 with the disk and but sparsely punctured. Seventh sternite with strong, 

 latéral, oblique ridges extending the length of the segment; those on 

 the eighth broadened, parallel with, but no longer than those of the 

 seventh. We cannot understand why it should be included in Glosso-
