coarse at the base, but I do not think that any spines are 

 present. 



Elis (Mesa) incerta, sp. n. 



c? . Niger, cano-pilosus ; clypeo maciola mediana ■minuta, tibiis 

 anticis supra pallide Jiavis ; . tegulis pedibusque fuscis ; alls 

 hyalinis, venis nigris ; pygidio haud inciso. 



Long. 13 mm. 



cS . Front coarsely reticulated, the vertex punctured ; thorax 

 closely but not coarsely punctured, median segment punctured- 

 rugose, abdomen finely and closely punctured. Pronotum shorter 

 than the scutellum, the anterior margins straight, the angles 

 subacute. First abdominal segment petiolate, the narrow petiole 

 scarcely more than half as long as the dilated apical portion of 

 the segment, which is constricted at the apex ; second segment 

 twice as broad at the apex as at the base, all the segments slightly 

 constricted at the base. Apical dorsal segment sparsely punctured, 

 without an incision, somewhat convex, subcarinate in the middle, 

 pointed at the apex, the lateral margins raised near the apex. 

 Third abscissa of the radius a little longer than the second, which 

 is fully twice as long as the fourth. First transverse cubital 

 nervure oblique, sharply bent close to the cubitus, second 

 recurrent nervure received just before one-third from the base of 

 the third cubital cell, curved outwards below the middle, the ends 

 slightly curved inwards. 



Sab. Howick, Natal (J. P. Cregoe) ; Cape Colony. 



This is very near the description of Plesia carbonaria Cam., but 

 in that species the seventh dorsal segment is said to be shortly 

 incised at the apex, and the fourth abscissa of the radius is almost 

 as long as the second or third.

Myzine capitata Sm. Cat, Hym. B. M, iii. p. 74 (1855), S . 



S . Niger, albido-pilosus ; clypeo, mandibulis, linea obliqua 

 utrinque supra antennas, pronoto fascia angusta postice, tegulis 

 basi, segmento dorsali primo fascia apicali emarginata, segmentis 

 dorsalibus et ventralibus 2-6 fascia hisinuata angusta fiavis ; 

 pedibxts -fiavis nigro-variegatis ; alls hyalinis, venis testaceis. 



Long. 14-17 mm. 



(J . Head large, much broader than the thorax, the cheeks more 

 than half as broad as the eyes ; anteniiae stout, the apical joint 

 truncate at the apex. Head rugose, thorax closely punctured, 

 median segment punctured-rugose ; abdomen shining, glossed 

 with blue, very finely and closely punctured. Pronotum shorter 

 than the scutellum, slightly narrowed anteriorly, the anterior 

 margin straight, the angles not prominent, posterior margin 

 widely arched. First abdominal segment petiolate, the petiole 

 only about half as long as the rather strongly swollen apical
