are known, 3 being recorded from Madagascar and 2 from Africa, 

 viz., S. conradti, Emery, from the Cameroons, and the new species 

 described below. 



Genus SIMOPONE, Forel. 

 In Grandidier's Hist. Madagascar, vol. 20, p. 139, 1891. 



Characters. 



% . Body more or less cylindrical ; bead parallel-sided. Antennae 

 11-jointed, scape very flattened and strongly incrassate towards the 

 apex. Thoracic sutures usually indistinct. Petiole articulated to 

 the 1st abdominal segment by a narrow surface. The constriction 

 between the 1st and 2nd abdominal segments very wide and rather 

 low down. Legs short ; claws dentate or pectinate. 



? . Unknown. 



3 . Clypeus very short ; frontal carinae convergent behind and 

 separated by a longitudinal sulcus. Mandibles triangular and 

 edentate. Antennae 13-jointed, scape short and thick, 1st joint of 

 nagellum very small. Mayrian furrows on the mesonotum strongly 

 defined. Petiole nodiform ; the constriction between the 1st and 

 2nd abdominal segments very strong. Anterior wings with two- 

 cubital cells, not completely closed. 



Simopone Marleyi, n. sp. 



£ . 7 mm. Eeddish ochreous yellow, mandibles and flagellum a 

 little darker, apical segment of abdomen except at its extreme base, 

 and the articular surface between the 1st and 2nd abdominal seg- 

 ments, black. Posterior half of thorax, petiole, legs and scape very 

 shining, the rest of the body moderately shining. Head, thorax, 

 petiole and lst-4th abdominal segments sparsely and shallowly 

 punctured ; the punctures are ill-defined and largest on the head, 

 smallest on the abdomen. The legs, antennae and mandibles are 

 sparsely and finely punctured. The anterior half of the head is- 

 microscopically longitudinally striate. The pubescence is sparse 

 and consists of short recumbent golden hairs. It is more abundant 

 on the 1st and 2nd segments of the abdomen, and very scanty on 

 the head and thorax. The apical margins of the petiole and 

 abdomen, and the sides of the apical segment bear some longer and 

 thicker hairs ; legs and antennae very sparsely pubescent. 



Head slightly narrower in front than behind, almost one-third 

 longer than wide, sides moderately convex, posterior margin feebly
