92 HYMENOPTERA. 



32. PONERA NiTIDA. 13. M. 



Worker. Length 2 lines. Black, smooth and shining : the 

 extreme base and apex of the scape, and the flagellum, ferruginous. 

 Thorax slightly swollen anteriorly, compressed in the middle, 

 and slightly widened to the apex of the metathorax, which is 

 obliquely truncated ; the scale incrassate, rounded in front and 

 truncate behind. Abdomen oblong, rounded at the base and 

 pointed at the apex, slightly constricted between the first and 

 second segments. 



Hab. Port Natal. 



33. PONERA PESTILENTIA. B.M. 



Worker. Length 5 6J lines. Black: the head longitudi- 

 nally and finely striated ; the mandibles large, shining, somewhat 

 elongate, their inner edge serrated irregularly with minute and 

 larger teeth, delicately striated, and with a few scattered punc- 

 tures ; the extreme apex of the antennae rufo-piceous. Thorax : 

 the pro- and mesothorax longitudinally striated, t^e striation on 

 the former curved anteriorly ; the metathorax transversely 

 striated ; the legs more or less obscurely ferruginous, nearly 

 black, with the apical joints of the tarsi usually dark rufo-piceous, 

 the calcaria pale rufo-testaceous, the anterior tarsi clothed with 

 ferruginous pubescence beneath. Abdomen oblong ; the first 

 segment truncated at the base, narrower than the second segment 

 and slightly strangulated at the apex ; the first segment is pinched 

 at the base beneath into a sharp caiina and furnished with a 

 short spine ; the peduncle elevated, subcylindrical, and ronnded 

 or blunt at its apex above. 



Hab. Sierra Leone. (Coll. Rev. D. F. Morgan.) 



34. PONERA SPINIVEXTRIS. B.M. 



Male. Length 6 lines. Black : with flavo-hyaline wings, 

 the nervures rufo-piceous. Head much narrower than the 

 thorax ; the antennae setaceous, longer than the thorax ; head 

 and thorax both covered with a thin downy pubescence; the 

 calcaria and claw-joint of the tarsi testaceous. Abdomen elon- 

 gate, longer than the head and thorax, the apical margins of the 

 segments constricted; the basal segment with a short blunt 

 tooth or spine at the base beneath ; the node of the peduncle 

 incrassate, obtuse above, and, as well as the abdomen, covered 

 with a short downy pubescence. 



Hab. Sierra Leone. (Coll. Rev. D. F. Morgan.) 

 In all probability this is the male of P. pestilentia.
