 colour becoming paler as it unites with the rufous colour 

 of the rest of the head ; the face coarsely and closely 

 punctured, the clypeus at the base sparsely punctured, its 

 apex almost impunctate ; thickly covered with short pale 

 hair ; the mandibles pale lemon-yellow, the teeth black ; 

 the hinder orbits obscure-yellow ; the palpi pale-yellow. 

 The two basal joints of the antennae are rufous. Thorax 

 rufous, shining ; the pro- and meso-notum closely and 

 rather strongly punctured, closely covered with a micro-

 with short fuscous hair. Propleurae closely and somewhat 

 strongly punctured, thickly covered with short fuscous 

 hair ; the base raised and paler in colour. The meso- 

 pleurse strongly punctured ; the metapleurae with the 

 punctures more widely separated, and smaller at base ; 

 at the base is a smooth, curved, and in front of the 

 spiracles is a wider, deeper, oblique, furrow, which becomes 

 wider towards the apex, and clearly separating the pleurae 

 into two unequal parts. Wings hyaline, with a fuscous 

 tinge, the nervures and stigma dark-fuscous. Tegulae 

 lemon-yellow. Abdomen not quite so dark-luteous as 

 the thorax ; the petiole with an elongated depression 

 extending from the front of the spiracles to a slightly 

 greater distance behind them, in the centre on the top ; 

 its apex being slightly wider than the base ; the ventral 

 surface of the second and third segments pallid lemon-
