EAST INDIAN HYMENOPTBRA. 309 



rugosely punctured ; its apex with an oblique slope, opaque, and 

 closely, finely rugose. Base of metanotum irregularly rugose, the 

 rest alutaceous. Pro- and mesopleurte closely, finely, but distinctly 

 punctured ; the meta- alutaceous. First and second segments of the 

 abdomen closely and distinctly punctured ; the first with a not very 

 distinct suture on the top of the basal slope; the second is smooth and 

 depressed at the base ; the third to fifth segments are minutely punc- 

 tured, the apical two smooth ; the second ventral segment is obliquely 

 produced downwards at the base. The second cubital cellule is much 

 narrowed at the top, being not one-fourth of the length of the third. 



A species not unlike 0. sikJdmensis, but is smaller and more 

 slenderly built ; that has the post-scutellum not so prominently 

 raised ; the second cubital cellule longer compared with the third 

 above ; the keel on the base of the first abdominal segment is 

 much more prominent, the base of the mesopleurse is not smooth 

 and shining, and it wants the wide-curved crenulated furrow. 



Odynerus tytides, sp. nov. 

 Black ; a line on the scape of the antennae beneath, a large mark 

 on either side of the top of the clypeus, a line along the lower margin 

 of the eye incision, a trilobate mark above the base of the antennae, a 

 mark, longer than broad, behind the top of the eyes, the top of the 

 pronotum, the mark narrowed in the middle, tegulfe, two marks, almost 

 united on the base of the scutellum, a mark on the pleurse below the 

 tegulae, the apex of the first abdominal segment above, of the second 

 all round, a narrow indistinct line on the third, the apices of the fourth 

 and fifth, of the sixth narrowly and the whole of the seventh, red. 

 Legs black, the apices of the four front femora, the four front tibite 

 except in the middle behind, the base of their tar.si and tbe hinder 

 tibi£e in front rufous. Wings fuscous-violaceous, the nervures and 

 stigma black. ? . Length, 10-11 mm. 



Hah. Darjeeling. 



Head and thorax closely and distinctly punctured, except on the 

 metanotum, the base of the mesopleurae, and the lower part of the 

 metanotum at the base. The upper part of the clypeus with large, 

 longish, clearly separated punctures, the lower part with the punctures 

 smaller, rounder, and closer together ; its apex with a sliallow incision, 

 its sides not forming teeth. Pronotum transverse. Base of scutellum 

 rugosely punctured, the apex closely, strongly longitudinally striated. 

 Post-scutellum strongly rugosely punctured, raised, its sides slightly 

 raised above into blunt teeth, the apex with a steep oblique slope. 

 MetapleuraB closely, irregularly striated, above almost reticulated, at 

 the base above is a space with clearly separated, fine striations ; the 

 lower part at the apex laterally projecting into a longish tooth. The 

 first and second abdominal segments are closely, distinctly, but not 

 very strongly punctured, as are also the third, fourth, fifth; the last 

 is impunctate. The second cubital cellule is narrowed at the top, 

 being there less than the length of the space bounded by the first 

 transverse cubital and the first recurrent nervures. 



The male is similarly coloured ; the tibite and tarsi are of a
