dilated at the base ; wings slightly dusky, with a fulvous tint towards the base, apex, and costa; 
wings and stigma fulvous ; marginal cell conical at the tip, second submarginal cell larger than 
the first, and separated from it by a nearly straight vein, the recurrent vein received in the 
middle of the second submarginal cell, beyond which the cubital vein is slightly thickened ; 
abdomen with the last joint compressed above at the tip ; anal plate deeply emarginate, the 
lateral processes acute. 
Obs. —This species approaches nearest to L. Hopei, but is distinguished from it by many of 
the characters given above. 
Obs. —Mr. Burchcll also captured a specimen at Guardamdr, in Brazil, on the 8th of 
September, 1828, at midnight, which differs from the above in having the wings rather more 
dusky, with the stigma darker and brown at the base, the vein separating the first and second 
submarginal cells, straight, and the anal plate not exposed. 
Species XIV.— Labidus Spinolcz , IV. Fuscus, cylindricus, capite atro, abdomine fulvo-fusco, 
pedunculo transverso, latcribus subrotundatis, alis infumatis, venis stigmateque subfuscis. 
Long. corp. lin. 6£. Expans. alar. lin. 11^. 
Taken at Meia Ponte, in Brazil, on the 16th of October, 1827^ by IV. Burchell, Esq. 
Very similar to L. Gravenhorstii, from which it differs in its darker-coloured wings and stigma ; 
the two basal submarginal cells are not so long, the vein separating them being less oblique, 
the legs darker coloured, the peduncle broader and not so square, the sides being rather 
rounded, the central surface scarcely angulatcd. 
Mr. BuTchell also captured another specimen at Caisara, in Brazil, on the 23d of October, 
1827, which although greatly mutilated appears to belong to this species.

lin. Sf. Expans. alar. lin. 12. 
Habitat in Brasilia. In Mus. D. Shuckard. 
Species XVI.— Labidus D'Orbignii, IV. (Sbk. Mon. Dor. p. 15.) Niger, brunneo-holose- 
riceus, pedunculo abdominis semicirculato, supra subconvexo, nervis alarum brunneo- 
testaceis, ocellis parvis, cellula marginali brevi postice acute angulata. Long. corp. lin. 
6£. Expans. alar. lin. 12. 
Habitat in America Meridionali, D. D'Orbigny. In Mus. nostr., e Mus. Reg. Paris, 
communic. 
Species XVII.— Labidus JFalJcerii , IV. Castaneo-fuscus, marginibus segmentorum abdo¬ 
minis lucidioribus, alis infumatis, venis fuscis, pedunculo transverso-quadrato, subtus baud 
angulato. Long. corp. lin. 5. Expans. alar. lin. 9^. 
Taken at Meia Ponte, in Brazil, on the 16th of October, 1827, by IV. Burchell, Esq. 
Body long, cylindrical, and of a dark brown colour, with the head darker and the margins of 
the abdominal segments brighter coloured, pubescent ; jaws rather short and curved, facial 
carinas extended along the outside of the front ocellus; ocelli large, lateral ones placed close to 
the eyes. Thorax gibbous before and behind. Peduncle transverse-quadrate, the sides 
slightly elevated, posterior angles not acute, ventral surface not angulated. Legs short and 
very slender; wings dusky, with brown veins and a dark brown stigma; marginal cell lanceo¬ 
late, two first submarginal cells larger, separated by a curved vein, the vein separating tho 
second and third submarginal cells straight and much longer than in L. D’Orbignii, the cubital 
vein closing the second submarginal cell behind not thickened ; the legs are very short and of 
a brick brown colour. 
Most like L. D’Orbignii, but smaller and of a browner colour ; the marginal cell differently 
shaped ; the legs not black, the wings darker coloured, with the second submarginal cell of 
equal breadth throughout.

vertice, thoracis dorso, ct stigmate alarum badiis; clypco tuberculis binis, acutis, instructo, 
etpedunculo transverso-quadrato, subconvexo. Long. corp. lin. 4f. Expans. alar. lin. 8J-.
