 if bent backwards ; 1st scapal joint short, not much longer than 

 the 2nd ; joints of the flagellum elongated, cylindrical, gradually 

 decreasing in length, clothed with a fine pubescence ; a single 

 somewhat longer hair is perceptible on each segment, above the 

 pubescence ; the antennse of the female are but little shorter than

* This description was written some time before I had read the description of 

 J'c«t7/o/ffi'^/^(7/a7(fa, Edw., with which my species is perhaps synonynions.thougli 

 this is not certain. In anj' case the genns (hjintioatcs ap])ears to be a sound one, 

 being based on the absence of a neck and on the conspicuously clubbed femora.
