MAHAKAMIA KAMPMEINERTI. 151 



the middle, the margins thickened ; very distinctly but not 

 densely punctured above, the punctures along the sides 

 larger than those along the middle; beneath flattened, the 

 flattened portion spattle-shaped and covered at the base 

 and along the sides with distinct punctures ; the sides of 

 the pygidium likewise punctured. 



Body beneath glossy ; prosternum in the middle densely 

 covered with shallow punctures, on the sides (especially 

 at the base) the punctuation agrees more with that of the 

 pronotum ; sides of meso- and metasternum distantly covered 

 with large shallow punctures, intermixed with very minute 

 ones; along the middle the punctuation is exceedingly mi- 

 nute and agrees pretty well with that of the abdomen ; 

 the apical margin of the last ventral . segment is faintly 

 bisinuate, the margin of the flattened middle portion 

 is slightly rounded and preceded by deeply impressed 

 punctures. 



Anterior legs very elongate (femora 28 mm., tibiae 32 

 mm.), the femora straight, their underside rough, rasplike, 

 it being covered with small warts or tubercles; the tibiae 

 regularly faintly curved, their underside provided all along 

 their length with rows of minute tubercles, separated by 

 a narrow well-defined furrow. Intermediate femora straight, 

 their underside beyond the base rugose and with a deep 

 rounded notch just before the knee-joint; intermediate 

 tibiae shorter than the femora, slightly widened out at 

 the underside at some distance from the base , the 

 underside with two lines of very short rufous setae, 

 these lines slightly diverging towards the base and sepa- 

 rated by a narrow keel. Posterior femora straight, some- 

 what shorter than the intermediate ones ; the tibiae as 

 long as the femora, their underside just like that of the 

 intermediate tibiae. The penultimate joint of all the tarsi 

 not widened, subequal to the second joint.
