the basal half of the hind cox pallid fulvous, the trochanters testaceous 
marked with black laterally ; the extreme base of the femora and their apex 
more broadly pale yellow ; wings hyaline, the stigma and costa black. Male. 
Length 7 m.m. 
The apical half of the clypeus, mandibles, except the teeth and the palpi 
pale testaceous, as well as a narrow line at the eyes opposite the antenne. Face 
smooth, shining, sparsely covered with short white pubescence ; the front and 
vertex alutaceous. Ocelli large, amber coloured. Pro- and mesothorax smooth, 
the mesopleure finely punctured, except at the apex above; the me’anotum 
finely, closely, transversely striated, more strongly so towards the apex ; the 
basal area twice longer than wide, narrowed towards the apex; the basal trans- 
verse keel obliquely turned to the outer apical side ; the second is near the apex 
and is broadly roundly curved ; there is a similar keel at the extreme apex. 
There are four small teeth—rounded, indistinct—on the apex of the hind femora 
beyond the large one. 
Pharsaliine. 
The curious genus Pharsalia, Cresson is placed by Ashmead in the Nototrachini 
(Bull. U. S. Nat. Mus. xxiii, 88) along with Nototrachus and Eugnomus ; by 
Szépligeti in a sub-family of the Ophionide, an arrangement with which I agree 
with him. cf. Gen. Ins. [chnewmonide Ophionide, 3. Its alar meuration, is 
not unlike that of Ropronza, a genus which has been referred to the Procto- 
trypoidea and which has also been made the type of a distinct family by Mr. J. C. 
Bradley. 
There are three points in the male which have not been pointed out by the 
writers who have described this genus, namely, the eyes in the male are pilose 
and the costa extends as a thickened vein, about two-thirds of the length of 
the radial cellule in front and beyond it ; in the male the genital armature largely 
projects—to a greater extent than the length of the last segment; it is in the 
form of two broad, knife-like projections, with the basal third wider than the 
rest. There are two spurs on the hinder tibie, one only on the four anterior. 
Ophionellus, West, appears to be identical with Pharsalia ; in O. fragilis, West, 
the type of the genus, the antennz are said to be from 30-40-jointed, as against 
25 in the species I have described. 
Pharsalia annulipes, sp.n. 
Black, the underside of antennal scape, two longish triangular marks on the 
top of the face, united above and continued as a short line along the eyes, 
reaching to shortly above the antenne, malar space, mandibles except the 
teeth, palpi, a short line on the upper, outer orbits, and the tegule, whitish 
yellow, legs ; the anterior rufo-testaceous, the tarsi paler, the coxe and basal 
joint of trochanters pallid yellow, the middle coxa, basal joint of trochanters, 
a band of the length of the second tarsal joint on the base of the tibie and the 
basal three tarsal joints, white, the femora rufous, the tibie of a darker rufous
