390 P. CAMERON. 



moderately large oblique, somewhat oval mark, and bands on the apices of the 

 basal 3 segments all round, yellow, tinged with fulvous. Legs black, the outer- 

 side of the tibise yellow. Wings reddish yellow, darker colored, more violaceous 

 towards the apex. J ■ Length to end of 2nd segment 12 mm. 



Clypeus, if auything, wider than long, its apex transverse, its sides forming 

 short blunt teeth ; the centre with longish, scattered punctures. Front and ver- 

 tex rugosely punctured. Base of thorax not quite transverse, the sides rounded, 

 slightly narrowed ; the apex has the sides only slightly dilated. Pronotum and 

 mesonotum, scutellum and postscutellum, except at the apex, strongly punctured; 

 the apex of postscutellum smooth, transverse. Metauotum closely, transversely 

 striated ; the sides blunt, the upper part bordered by a narrow curved keel. Pro- 

 pleurce and niesopleurBe closely, strongly punctured; the metapleurse closely 

 striated. There is a wide, oblique furrow on the basal half the mesopleurae. 

 Basal segment of abdomen short, cup-shaped, uot separated from the 2nd, with 

 which it is continuous. 



Belongs to Saussure's Section B. a, Syn. of Anier. Wasps, 237. It 

 resembles closely the species of the nasideiis group. The % has all 

 the abdominal segments bordered with yellow, the yellow on the 

 head and thorax being broader ; the clypeus is entirely yellow ; it is 

 as long as wide, its sides project into short triangular teeth ; the 

 space between them is slightly but distinctly rounded. The mark 

 over the antennae is broad, rounded aud narrowed below, transverse 

 above. The flagellum is black, except the hook and the apical two 

 segments below ; the hook is long, curved and reaches to the base 

 of the 3rd segment. In both sexes the anterior nervures, the costa 

 and stigma are reddish fulvous, the teguhe are large, reddish fulvous, 

 with an oval fuscous mark at the base. 



Odyiierus (Pacliodyuerus) aslra-us sp. nov. 



Black; thickly covered with a silky fulvous pile; a narrow transverse line 

 over the antenna?, a short line opposite the antennae, a short one near the base 

 of the antenme, the upper edges of the pronotum all round, a line on the base of 

 the propleurse in the middle, a mark on the base of the tegulse, a small mark on 

 the pleurte below them, postscutellum, the upper outer angles of the metauotum, 

 a line on the 1st abdominal segment above and on the others all round, luteous. 

 The anterior tibise in front and the base of their tarsi luteous. Wings reddish 

 yellow, their apex tinged with fuscous; the stigma and basal nervures luteous, 

 the apical nervures darker colored. $> . Length to end of 2nd segment 8 mm. 



Front and vertex strongly aud closely punctured. Clypeus longer than wide, 

 above almost impunctate; the apex with longish, scattered punctures; the apex 

 is wide, almost transverse, the sides projecting into indistinct teeth. Thorax 

 rather strongly and closely punctured ; the apical slope of postscutellum smooth, 

 transverse. Upper half of the sides of metauotum sharply keeled; the apical 

 half transversely striated. Apex of the 2nd segment and the following closely 

 somewhat strongly punctured; the 1st segment cup-shaped, as wide as the base 

 of the 2nd.
