hinds legs on a slide with the type head of Elachertetrastichus purpureiis Girault. 
Genus DIAULOMORPHA Ashmead. 
The generic diagnosis given by Ashmead (1904) disagrees with the original description 
and since the former is not stated to be given upon re-examination, f must follow the latter. 
According to the original description the antenna? are 8- jointed, the funicle 3-jointed (leaving 
as alternatives 2- or 3-jointed club and one or no ring joints) ; flagellum subcompressed; 
postscutellum half the length of the scutellum. Metathorax (propodeum) short, with a median 
carina. Marginal vein nearly as long as the submarginal, the stigmal and postmarginal veins 
more than half the length of the marginal. Scutellum with two delicate grooved lines.

nearly twice wider than long; stigmal vein nearly two thirds the length of the marginal; 
pronotum semicircular, not short, narrower than the mesonotum; abdomen ovate, depressed 
above, hardly as long as the thorax; antennas 9-jointed, the flagellum subclavate, the funicle 
4-jointed.
