MONOGRAPH OF THE DORYLIDES. 
Entirely of a fulvous red colour (except the head, which is dark chesnut) and shining, being 
hut slightly pubescent; the jaws of moderate size, the clypeus entire, the ocelli very large, 
the facial carinae very strong, and extending on each side of the front ocellus, forming a strong 
angle beneath it; the antennm are long and slender, tho basal joint longer than in L. Klugii; 
the thorax is not very gibbous in front, the peduncle is narrower than the thorax or abdomen, 
and of a squarer form than in any of the preceding, with tho angles acute ; the abdomen is 
very long and cylindric, not thickened towards the tip as in L. Klugii. The wings are broad 
and almost colourless, with thin brown veins ; the stigma large and blackish ; the marginal cell 
is slightly attenuated towards the tip ; the first and second submarginal cells are large, separated 
by a slightly curved vein; the recurrent vein is received at the middle of the second sub- 
marginal cell, beyond which the cubital vein is thickened; the anal plate is deeply and widely 
emarginatc ; the lateral processes very acute. 
f T Peduncle as long as broad. 
Species XX.—Labidus Rojnandi, Shk. (Mon. Dor. p. 17). Rufo-testaceus; vertice badio, 
stigmate alarum brunneo-fusco, et pedunculo abdominis quadrato-convexo; mandibulis 
brevibus, tenuibus ; abdominis segmentis posticis, subcompressis. Long. corp. lin. 4J. 
Expans. alar. lin. 7^. 
Inhabits Brazil (Mus. D. Shuckard). Also taken at Canga, in Brazil, on the 4th of November, 
1838, during the night, by W. Burchell, Esq. Mr. Burchell possesses a specimen 4 lines 
long, and with the wings expanding only 7 lines, which I refer to this species, although the 
anal plate is not exposed, and the wing-veins exhibit the following distinctions, which are, 
I apprehend, to bo regarded as irregularities :—The right fore-wing has four submarginal cells, 
a small supplemental one (forming a third) being interposed between the ordinary second and 
terminal cells. This little cell is very narrow in front, but broader behind. The left fore¬ 
wing has also four submarginal cells, but here the small supplemental cell is interposed between 
the ordinary first and second ; it is of a triangular form, and does not extend upwards to the 
marginal cell, the second transverse-cubital vein being in fact furcate at a little distance from 
the marginal cell. 
UNKNOWN SPECIES. 
Species XXI .—Labidus Pertii, Shk. (Mon. Dor. p. 18). 
Syn. — Lab. Latreillii, Perty, Del. An. Art. Br. p. 138, t. 27, f. 11. 
Obs.—Dorylus mediatus , Fabr. Syst. Prez., p. 428. (Labidus? mediatus, Shk. Mon. 
Dor. p. 18.) preserved in the Royal Museum of Copenhagen, has been examined by 
Dr. Ericbson, who informs me that it is a male Mutilla, having the third joint of the 
antenna? (instead of the base of the second, as described by Fabricius) ferruginous. 
^Enictus, Shk. 
This genus differs from Labidus in the venation of the wings, and 
geographical situation; and from Dorylus in the small size of the 
body, the long curved mandibles, and the slender cylindrical thighs; 
whilst it is at once separated from Rliogmus by possessing only 
one recurrent vein. 
Mr. Shuckard founded the genus in his Monograph on the 
Dorylidse upon two specimens of a single species brought from 
Poonah, in Bombay, by Col. Sykes. I have, however, long had a 
note of a second species in the Cabinet of the Linnsean Society, and 
now possess, by the kindness of W. W. Saunders, Esq., President 
of the Entomological Society, F.L.S., &c., a specimen of the species 
described by Mr. Shuckard, taken in Northern India, by Lieut. 
Campbell.
