Hah. — Ferozepore — March and April. 



The puncturation on the clypeus is les3 close than it is on the front and 

 vertex; there is a narrow smooth band on its apex. Puncturation on the 

 thorax close, distinct, on the pleura almost running into reticulations. Base 

 of hind metatarsus hardly half the width of apex of tibiae ; the spurs and 

 tarsal spines are white ; the apical 2 tarsal joints and the claws reddish. 



The ^ has the antennae as long as the head and thorax united ; its apical 

 segment is densely covered with white pubescence, in the centre are 2 stout 

 teeth separated by a semicircle, on either side of these are 2 short teeth, with 

 a blunt tubercle beyond them ; the fore coxae are armed with stout, bluntly 

 pointed teeth. 



DIPLOPTERA. 



Odynerus rufo-himacvlatus, sp. nov. 



Black ; a broad, curved mark on the sides of the upper two-thirds of the 

 clypeus, a dagger shaped mark over the antennae, its lower part distinctly 

 narrowed, underside of antennal scape, a line on the upper half of outer 

 orbits, an almost interrupted line on the pronotum, rorndly ijcrrcwed en 

 the sides behind, an irregular mark below the tegulae, the base and apex 

 of the latter, a longish line rounded on the innerside, on the sides of 

 the scutellum, a squarish one on the sides of post scutellum, a narrow 

 line on the sides of the 1st abdominal segment, a wider, trilobate one 

 on the 2nd, a short, bilobate one on the centre of the 8rd and 4th and 

 a shorter, wider curved one on the 5th and the apex of the 2nd ventral, 

 pale yellow. Wings clear hyaline, the stigma brown, the nervures blackish ; 

 the apex of the clypeus and 2 large spots near the centre of the 1st 

 abdominal segment rufous, legs red, the middle coxse below, the 4 anterior 

 tibiae below and the tarsi pale yellow. 



Length, 7 mm. 



Bah. — " India ". In my collection. 



Clypeus slightly longer than wide, the lower two-thirds of the centre keeled 

 on either side, the ape.x clearly separated, transverse. Underside of flaj^elium 

 light orange-brown. Head and thorax closely, not very strongly, punctured. 

 Base of thorax almost traijsver&e, the sides not projecting ; apex of post- 

 scutellum smooth, gradually narrowed to a blunt point, sides of metanotum 

 broadly rounded. 



Allied to 0. humbertianus, Sauss, which has the 2Dd abdominal segment 

 tuberculate near the base in the centre and laterally at the apex with a 

 smaller tubercle. In the present species the depression on the metanotum 

 becomes gradually wider towards the apex ; the apical teeth on the metanotum 

 are large, triangular, as wide at the base as they are long. The puncturation 

 on the clypeus runs into striae at the apex. The frontal mark vaiit s in form, 

 and the reddish marks on the base of the abdomen vary also in size and 

 form.
