432 DESCRIPTION OF TWO NEW 
the parasitic specimens to be forms new to science. One 
of these is a new species of the genus Phora ; the other 
I regard as possessing characters sui generis, and hence 
define it under the generic title Platyphora, at the 
same time bestowing on the species the name of 
the discoverer, who worthily pursues entomological 
researches, spite of many pressing public engage- 
ments. 
The subjoined descriptions embrace the diagnostic 
peculiarities of the insects in question. 
“PHORA FORMICARUM, n. sp.—Nigro-cinerea, fronte 
setosa, caniculata ; antennis mediocribus, cinereis; pal- 
pis magnis, flavis; halteribus flavidis; pedibus totis 
pallide flavis, inermibus, tibiis intermediis unicalcara- 
tis, posticis modice dilatatis ; alis subhyalinis, nervo 
secundo simplici, nervulis vix undulatis. Long. vix 
$ lin. : 
Frons broad, grey, bristly, two large bristles being 
close to the eye-margin ; down the centre is a deep im- 
pressed channel, which at its lower end joins a channel 
above the antenne, and at its upper end a channel round 
the raised vertical triangle; the space between these 
two latter channels (comprising the true frons) is about 
once and a half broader than deep; on the vertical 
triangle are two bristles; the third joint of the an- 
tennz is moderately large, ovate, grey ; the arista short, 
somewhat yellowish, almost naked; the palpi con- 
spicuous, all pale yellow, with a few short black bris- 
tles at the tip; on the cheeks are some short black 
bristles. 
The thorax is grey or brownish grey, broad, not much 
arched, the disk being nearly flat, and on the hinder 
part absolutely concave ; on the disk there are no long 
bristles, but a dense clothing of rather short black 
bristles; along the side of the thorax between the 
humeri, the base of the wing, and the scutellum are 
some long black bristles, and two on the thorax just 
before the scutellum ; on each side of the scutellum are
