Ptcry go gramma, gen. nov. 



Head strong-ly transverse, ocelli in a triangle with very wide 

 base, the posterior ones touching the eye-margins. Antennae 

 apparently six-jointCid, counting an extremely short ring-joint, 

 the three terminal joints apparently form a widely dilated but 

 pointed club, the terminal joint in some aspects 'almost spinose 

 in appearance; pedicel widely ovate, the scape also apparently 

 somewhat dilated. Owing to the thinly laminate character of 

 the joints, the antennae are subject to much distortion. Scutel- 

 lum rather less long t'han the mesonotum ;the metanotum point- 

 ed posteriorly and produced over the base of abdomen ; the lat- 

 ter elongate and acuminate, twice as long as the thorax, and 

 apparently laterally compressed somewhat like some Mymari- 

 ilae; the ovipositor exserted for :a length nearly equal to the 

 hind tarsi. Wings wjth the lines of hairs rather confused, and 

 about 7 or 8 in number, the apical fringe not verv long.
