Testaceous, witli the clypcus, liind tibiae, and all the tarsi 

 reddish. Tiie form is elongate and cylindrical. The head 

 is small and deeply punctured, and the clypeus transverse, 

 with the margin strongly rcflexed and bilobed in front. 

 The pronotum is very linely punctured, rounded at the sides, 

 with the front angles nearly right angles, the hind angles 

 very obtuse and the base tinely margined and very gently 

 rounded. The scutelluin is finely punctured and the elytra 

 bear irregular rows of fine punctures, the second interstice 

 being wide and irregularly punctured. The pygidium is 

 rather rugosely but not deeply punctured. The metasternum 

 is finely and densely punctured and clothed with fine yellowish 

 pubescence. The front tibia is tridentate and the inner claw 

 of the front tarsus is cleft. 



^ . The inner front claw is very broad. The clypeus is 

 shining, a little excavated on each side and the lobes 

 pointed. 



? . The clypeus is rugosely punctured, the lobes blunt,

This insect, together with that which follows and 

 A. siamensis, Nonfr., form a peculiar group distinguished by 

 the bilobed clypeus and in the male by a form of oedeagus 

 the paramera of which end in transverse laminoe. A. hilobata 

 is extremely like A. siamensis, of which Dr. Ohaus has 

 kindly sent me for examination a typical male specimen, but 

 it is a little more elongate and lets stout. It is doubtful, 

 however, if the absolute discrimination of the two is 

 possible without examination of the genitalia, which are very 

 different. They are shown in the accompanying sketches, 

 the oedeagus of A. hilobata (fig. 1) being longitudinally 

 grooved and the two terminal laminte meeting in a sharp 

 angle behind. In that of A. snimensis (fig. 2), both groove
