these are usually more or less obliterated; the fourth and 
following segments covered with golden pubescence.

Male.— Agreeing with the other sex in size and general 
resemblance; the wings fuscous at their apex, the ‘tegule 
proportionally larger. The antenne a little longer than 
the head and thorax, ferruginous, with the two apical 
joints black, enlarged, flattened and forming a somewhat 
pear- -shaped node or club. The posterior femora swollen, 
widest at their apex; the tibie have their apical half 
dilated, their inferior apex being compressed into a thin, 
rounded, flat plate. The apical margins of the segments 
of the erinien strongly punctured, ailie entire abdomen 
being smooth in the female. 
Of this remarkable genus two females were obtained 
by the British Museum from Captain Laing’s collection ; 
they were taken near Lucknow some time previous to 
1870. Mr. Rothney captured both sexes near Pulta, 
Barrackpore ; he reports the species to be extremely 
local. The plant it frequented appeared to be a species of 
Pulicaria.

Celioxys argentifrons. 
Male.—Length 44 lines. Black: the head and thorax 
semi-opake and very "closely punctured; abdomen shining 
rather closely and finely punctured; wings slightly fuscous, 
becoming clear hyaline towards the base. The face densely 
covered with silvery-white pubescence; the cheeks, the 
thorax at the sides and beneath, the legs, and the abdo- 
men beneath, have a fine, short, silvery-white pubescence; 
the segments of the abdomen have each a lateral patch of 
fine, short, white pubescence; the patches extend over 
both the basal and apical margins, they are widest late- 
rally, and are attenuated to a point inwardly, and do not 
extend to the middle of the segments. The apical seg- 
ment has a slender, acute tooth on each side at its base ; 
the apex deeply notched or grooved, the lateral projections 
form short rounded teeth above, and short acute ones 
beneath, all being of the same length. The tooth at the 
lateral angles of the scutellum is very short and blunt. 
Celioxys basalis. 
Female.— Length 7 lines. Black: the abdomen shining, 
elongate and tapering to an acute point. The vertex,
