Lateral ocellus distinctly closer to the median than 
to the eye, as far from the eye as from each other, twice 
farther apart than far from the median, occiput margined 
above. In the general diagnosis of the genus in widest 
sense, runs to fulvipes (the spiraeular sulcus is black) ; 
then to maculatipennis, but the dorso-lateral groove is 
also black and there is a median groove upon the scutel- 
lum. In fulvipes , the lateral grooves of the scutellum are 
present (the ovipositor is distinctly longer here, nearly as 
long as the body). Maculatipennis is grooveless (scutel- 
lum) and distinctly smaller and lacks the black dorso- 
lateral groove (propodeon) or sulcus. 
Mercatori bears a distinctly shorter ovipositor, three 
grooves upon the scutellum and the dorso-lateral groove 
(propodeon) is concolorous: also the size is a half smaller, 
the second wing with only ten lines of discal cilia to the 
other’s fourteen ; the neck of the stigmal vein is longer 
than wide here but in mercatori square. The sulci of the 
propodeum are not black in maculaiipennis ; nor is there 
any black upon the pro-and mesoventer. The species 
fulvipes bears a black triangle upon the proventer, the 
meson of the mesoventer is widely black (but distad less 
widely). In this new species, only the base of the tri- 
angle, or all of it, faintly, the mesoventer ’s ventral median 
line black only narrowly. 
The species herndoni is flavous, bears no grooves 
upon the scutellum, the lateral ocelli are equidistant 
(apparently), (at least one or more abdominal bands), 
and is a half smaller. From limoni, this species differs 
in that the ovipositor and the body are somewhat longer; 
the flagellum, the pedicel above except at the apex, and 
the scape at the apex above widely, are black ; the first 
funicle joint is distinctly longer, distinctly exceeding the 
pedicel (equal in the other, limoni ) ; the dorsal thoracic 
sutures are not black ; in limoni , according to its descrip- 
tion, the scutellum is trisulcate, but I could not confirm 
this, and only the median groove was re-seen, which I 
think is the correct interpretation of this species. Its so- 
called variety, however, morleyi bears the three grooves. 
The basal nerve bears six larger cilia, these smaller 
than the large submarginal vein’s bristles (8) ; nine 
similar cilia continue (towards base after junction with 
the cubital nerve) ; the basal vein is chitinous, crossing 
the cubital as usual and curved distad. Third mandibular
