THAUMATODRYINUS gen. nov. 



Agrees v/ith Neodryinus and other genera in the structure of 

 the front legs but differs greatly in otfier characters. Head in 

 front view very strongly transverse, subquadrangular, the cheeks 

 at the base of the mandibles sharply and prominently angled, the 

 vertex strongly convex and subtumid. In dorsal aspect the head 

 is very strongly transverse, more than twice as wide as long, the 

 ocelli being placed in a nearly equilateral triangle. Mandibles 

 with three strong teeth and a small inner one. Maxillary palpi 

 extremely long, extending back far behind the head. Antennae 

 filiform, very long and slender, as long or a little longer than 

 the entire insect; third joint a little longer than the thick scape; 

 fourth subequal to or a little longer than the third; fifth and 

 sixth subequal, distinctly longer than the fourth, each of these 

 two with a minute black tubercle before the middle, bearing a 

 few very fine long hairs, quite different from the general pubes- 

 cence; seventh with a similarly clothed tubercle at the middle; 

 eighth much shorter than the seventh and with a similar tubercle 

 near the contracted apex; ninth as the preceding, but shorter; 

 tenth with a tubercle at the middle and another at the apex and- 

 strongly constricted after the first tubercle; all these tubercles 

 bearing hairs as already described. Pronotum about as long as 

 wide, or as the mesonotum, in profile rising strongly upwards, 

 and this curve continued by the mesonotum, its hind angles at- 

 taining the tegulae. Parapsidal furrows fine and feeble, but quite 

 evident, subconvergent, but still widely separated at the base. 

 Propodeum rather long, about as long as wide.
