EAST INDIAN HYMENOPTERA. 15 



Crabro lysias, sp. nov. 



Black ; the scape of the antennae, an interrupted line on the pro- 

 notum, and two large transverse marks on the second and fourth 

 abdominal segments, yellow ; the greater part of the front tibiae, the 

 middle at the base and apex, the hinder, except in the centre behind, 

 and the basal joint of the hinder tarsi, yellow. Wings hyaline, the 

 stigma fulvous, the nervures darker. ? . Length, 9-10 mm. 



Hah. Himalayas. 



Clypeus thickly covered with dark silvery pubescence, and distinctly 

 keeled in the centre. Mandibles punctured strongly, but not closely 

 at the base ; the apical teeth equal in size, large. Front and vertex 

 closely, rugosely punctured, opaque, more shining along the lower 

 inner orbits. Ocelli in a curve. Mesonotum opaque, closely rugose, 

 a narrow furrow in the centre of the basal half; the punctures on the 

 scutellum run into striae at the apex. Metanotal area irregularly, 

 closely longitudinally striated ; a deep furrow in its centre ; the furrow 

 becomes wider towards the apex, and is united to the furrow on the 

 apical slope, which is obscurely transversely striated. The upper part 

 of the propleurae obliquely striated ; below, at the apex, are three stout, 

 oblique keels. The upper part of the mesopleurae is stoutly striated, 

 the striae curved ; the lower part punctured, the punctures running 

 into striae ; the basal furrow is wide. Metapleurae obscurely striated. 

 Tibiae stoutly irregularly spined. The basal half of the pygidium bears 

 large punctures ; the apical is smooth, hollowed, narrowed, and keeled 

 laterally ; it is fringed with long golden hair. 



Comes near C. argeiitatus and C. hellus in Bingham's ar- 

 rangement. 



Crabro menyllus, sp. nov. 



Black ; the scape of the antennae, except for a brownish line above, 

 an interrupted line on the prouotum and two transverse large marks 

 on the base of the second abdominal segment, yellow. Wings hyaline, 

 the nervures and stigma dark fuscous. ? . Length, 7 mm. 



Hab. Himalayas. 



Front and vertex closely and distinctly punctured, the former more 

 strongly than the latter, which is not furrowed, and is covered below 

 with silvery pu.bescence. Ocelli in a curve. Clypeus not keeled or 

 furrowed in the centre ; thickly covered with silvery pubescence. 

 Mandibles black, piceous towards the apex. Mesonotum closely and 

 strongly punctured, and thickly covered with longish pale pubescence. 

 Scutellum closely punctured, less strongly and obscurely striated at 

 the apex ; the extreme apex shining. Post-scutellum closely punc- 

 tured, with a smooth space in the centre. Metanotum aciculated, the 

 base closely striated, the striae stronger and oblique on the sides ; the 

 apical slope aciculated and closely, but not strongly, obliquely striated. 

 Mesopleurae distinctly, but not very closely, punctured ; the meta- 

 closely, finely obliquely striated. Petiole as long as the second and 

 third segments united ; it becomes gradually wider towards the apex ; 

 the third and following segments are thickly covered with fulvous
