 of funicle 1 which is longest, somewhat longer than 2 or .3 which are elongate and subequal ; 

 funicle somewhat less than twice longer than wide, somewhat shorter and thicker than the 

 pedicel. Head with very fine surface sculpture and distinct, moderate-sized thimble punctures. 

 Body similar to that of the genotype except that the abdomen is longer than the thorax, the
