120 Orper—HYMENOPTERA. 
trochanters black; posterior tibiee with a double row of serratures outside. Abdomen shining and closely 
punctured, base and apex coarsely so. 
Fig. 5a@ represents the front of the head, and 54 the fore leg, shewing the curved transverse depression 
near the extremity of the tibiw. The antennz are short, the articulation between the eighth and ninth joints 
very indistinct, the ninth joint large and kidney-shaped, and the tenth joint very minute and slender.

Puate XXII, Fre. 6. 
Niger, capite thorace abdomineque immaculatis, punctatus: capite supra rugoso ; antennis gracilibus nigris, 
articulis 4-7 obscure albidis ; pedibus nigris, gracilibus, geniculis, tibiisque prasertim posticis extus albidis ; alis

Habitat ; ‘ Boulogne,’ prope Parisias. In Mus. Britann., communic, D. Latreille (No. 611). 
This species is only half the size of O. coronatus, and the sexes are alike in colour, so that it cannot be 
regarded as a variety of that species.

A considerable number of female specimens of this species were obtained by the late Mr. Raddon, the 
engraver, from skimmings of raw turpentine imported in barrels, as collected in North America. 
A male of this species from Nova Scotia (Redman), in the British Museum, is five lines long, and seven 
lines in the expansion of the fore wings; the antennz are simple, black, with a small white spot in front of the 
third and fourth joints, near the tips; the face with two small, transverse, white lines extending from the fore 
inner margin of the eyes, the knees and front of all the tibie are white: the abdomen with a small triangular 
white spot at the tip above, the wings not so strongly coloured as in the female, but with the same arrangement 
of colour on the submarginal vein, and in the submarginal cell.
