90 Cameron, Hyiucnoptcra Orientalia. 



This genus comes near to Dorydes, with which it 

 agrees in some respects ; but may readily be known from 

 it by the transverse probrachial nervure being interstitial 

 and consequently the jjnebrachial and the probrachial 

 areolets equal in length, and by the probrachial areolet 

 in the hind wings being divided into two by a transverse 

 nervure. In Doryctes there are only five area; on the 

 metanotum, instead of ten as in our genus. Characteristic 

 is the curved apex of the radius and of the base of the 

 cubital nervure.

Long. 6, terebra 3 mm. 



Antennae black ; the flagellum densely covered with 

 short stiff pubescence ; the scape shining, sparsely haired. 

 Head shining ; below the eyes is a large, dirty-testaceous 

 mark ; front and vertex sparsely pilose ; impunctate ; the 

 space over the antennae is minutely, irregularly striated; 

 there is a shallow, small, round fovea above each antenna ; 

 the face is strongly aciculated, especially in the middle ; 

 the projecting clypeus is more strongly punctured; over 

 its top is a curved furrow. Mandibles testaceous ; the 

 teeth black; the palpi white. Mesonotum opaque, strongly 

 aciculated ; the parapsidal furrows transversely striated ; 

 in the middle of the central lobe is a shallow, punctured, 

 longitudinal furrow. Scutellar depression large, deep, 

 closely punctured, keeled down the middle. Scutellum 

 closely punctured ; the post-scutellum depressed, bordered 

 by distinct keels laterally. The base of the median seg- 

 ment is smooth; down its middle runs a straight keel; 

 on the sides, inside the spiracles, is a curved keel, the curve 

 being towards the centre ; in the middle, joined to the
