I20 Mr. Cameron on 



lower part of cheeks densely covered with silvery hair. 

 Front raised, furrowed down the centre, bearing large, 

 distinct punctures, narrowed before the antennae into a 

 wedge. The eyes at top are separated by the length of the 

 second and third antennal joints united ; ocelli rather 

 widely separated ; clypeus with a raised margin, sharply 

 rounded at the apex. Mandibles reddish beyond the base. 

 Thorax shining, covered with long fuscous hair ; mesonotum 

 rather strongly punctured ; the scutellum and fore part of 

 the mesopleurae slightly punctured ; the hinder part of the 

 latter impunctate. Metanotum strongly transversely 

 striolated, the strise wide apart ; there is a wedge-shaped 

 depression in the centre of the upper part ; the depression 

 with a keel down its edges ; there are two lateral keels 

 and the posterior part of the metanotum is widely excavated 

 in the centre ; this portion having a gradual rounded curved 

 slope. Petiole as long as the mesothorax, clavate ; fully 

 one-third longer than the second segment ; the latter is a 

 little longer than the third, and both have an elongate fovea 

 on the top at the apex. At the apex the abdomen is 

 sparsely pilose. Femora sparsely haired ; tibiae and tarsi 

 closely pilose ; spurs pale testaceous. 



Trypoxylon accumulator. 



In this species the front is not much raised on either 

 side of the central furrow, which is wide but shallow ; the 

 eyes at the top are separated by about the length of the 

 third antennal joint, at the bottom below the antennae by 

 fully more than the length of the third. The third joint of 

 the antennae is nearly one-half longer than the fourth. 

 Clypeus broadly carinate, the apex projecting, broadly 

 rounded. Petiole longer than the thorax, rather abruptly 

 dilated towards the apex ; the second segment distinctly 

 shorter than the third.
