shining, and sparingly and delicately punctured. Head small and 

 more strongly punctured than the thorax ; a deeply impressed 

 line in front of the anterior ocellus, extending to the base of the 

 clypeus, which is smooth, shining and convex, with its anterior 

 margin rounded ; the mandibles punctate- striate, with four or 

 five black acute teeth ; the antennae and apical joints of the tarsi 

 pale rufo-testaceous ; the mesothorax with two central approxi- 

 mating lines anteriorly, which terminate a little before the middle 

 of the disk, also a faintly impressed line opposite each tegula ; 

 wings smoky, nervures dark ferruginous. Abdomen large and 

 ovate, the nodes of the petiole transverse, the anterior lateral 

 angles of the second node acute. 



Hah. Hong Kong.

Male. Length 7 lines. Head, thorax and nodes of the pe-

 with the nervures dark ferruginous, the posterior wings palest. 

 Abdomen oblong -ovate, slightly narrowed posteriorly ; the first 

 node of the abdomen, viewed above, rounded, the second trans-
