segment is oblique ; obscurely punctured ; the sides at the 

 base distinctly and strongly reticulated, this being also

 the punctuation running into indistinct reticulations. The 

 lower part of the propleurse strongly irregularly striolated, 

 distinctly margined at the base and apex ; the upper part 

 of the mesopleurae smooth in the middle ; the posterior 

 half raised ; the base of the raised part crenulated ; 

 the basal part of the lower region bearing large, 

 deep, round, distinctly separated punctures ; the punc- 

 tured part of the mesonotum is separated from the 

 upper and basal by an oblique furrow. The anterior 

 legs are pale testaceous, except the coxse which are black 

 and the middle femora which are infuscated ; the hinder 

 coxae are black, strongly punctured on the basal half, the 

 apical part closely striated in the middle above ; the sides 

 and lower part thickly covered with white hair ; the hinder

 versely striolated and oblique ; its centre is strongly 

 furrowed ; the sternum between the four hinder legs is
