ELA.CHERTOMORPHA Ashmead, geu. nov. 



This genus resembles Elachertus Spinola, and could be easily mistaken for it, 

 except that the hind tibise have two apical spurs. From Leucodesmia Howard, it is 

 separated by the antennse being ten-jointed and by having the scutellum grooved.

 lines on the scrobes, honey yellow ; thorax and abdomen seneous black, the former 

 shagreened, with the scutellum rugulose and the metanotum carinate ; scape of an- 

 tennse and the legs, except as noted, honey yellow, the middle and hind coxse black, 

 the front and middle femora basally, more or less dusky, the hind femora medially

 abdomen is rounded, smooth and shining, shorter than the thorax, with a short 

 petiole.
