21, (hitherto undescribed), 9*5 mm. Black, the vertex and occiput, 

 and the disc of the pronotum with a faint reddish brown tint, flagellum, 

 tarsi and apices of the femora reddish brown, scapes and mandibles 

 piceous, the masticatory margin of the latter ferruginous. The 

 fundamental sculpture reticulate-punctate like that of Petersi, but 

 much finer and more superficial. The anterior half of the cheeks 

 with a few large and shallow punctures. Pilosity greyish, very scanty, 

 almost obsolete on the head and thorax. Pubescence greyish, less 

 apparent than in Petersi. Head, excluding the mandibles, nearly 

 one-fourth longer than wide, the sides fairly convex, the posterior 

 margin shallowly concave, the posterior angles rounded, more narrowed 

 in front than in Petersi. Mandibles 7-dentate, feebly shining, micro- 

 scopically reticulate-punctate, and with a few large piligerous punc- 

 tures. Clypeus strongly carinate, lobed, the anterior margin of the 

 lobe straight and crenulate. Frontal carinae closer together than in 

 Petersi, two-thirds longer than their greatest distance apart. Frontal 

 area distinct. Eyes small, placed behind the middle. The scapes not 

 flattened, just reaching beyond the occiput. Pronotum moderately 

 convex transversely, very feebly so longitudinally, with rounded but 

 fairly distinct shoulders. Mesonotum as long as wide. Metanotum 

 distinct, three times wider than long. Epinotum with both faces 

 more oblique than in Petersi. Scale a little higher than the petiole 

 is long, the anterior face convex transversely, feebly so vertically, 

 the posterior face concave, the dorsal edge obtuse. Tibiae cylindrical, 

 armed with a few setae below, not densely pilose as in Petersi and 

 Eugeniae. Very much like Petersi, but much smaller and with differ- 

 ently shaped head, scale and tibiae. 



£ minor, 7*5-8-5 mm. Pubescence somewhat more yellowish than 

 in the 2J.. Apical margins of the abdominal segments narrowly 

 testaceous. Head very long and narrow, excluding the mandibles 

 twice as long as wide. The sides in front of the eyes straight, slightly 

 convergent anteriorly, behind the eyes moderately convex, the 

 posterior margin almost straight. The scapes extend beyond the
