 sexes before me, the male has the anterior tarsi nuich dilated, 

 the penis is stout and moderately curved ending in a broad

 the middle l)ut leave a narrow groove or division ])etween them; 

 in the type tlie underside and legs are llavous, in the specimens 

 now before me, they are more or less black but I am not able 

 to tind any other differences of any importance.
