222 Timehri. 
Clypeus longer than wide, the apex with a distinct, transverse raised margin. 
The 1st abdomical segment cup-shaped, the top of the basal slope with a not 
very distinct ridge. 
Odynerus reticulatus, sp. 1. 
Black, densely covered with pale golden pile, the thorax more densely so 
than the abdomen, a narrow line on the sides of the upper half of clypeus, one 
on the inner side of the base of mandibles, the base of post-scutellum, broad 
bands on the apex of abdominal segments 2-5, the sides of the 6th the 2nd to 
5th more narrowly below and the whole of the 6th, reddish orange ; the raised 
angle on the top of the metanotum ofa paler yellowish colour, legs entirely 
black, the tibial spines pale ; wings hyaline the anterior margin tinged with 
fulvous, the apex slightly violaceous. The raised part of the mesopleure 
reticulate d, the sides of the metanotum more strongly reticulated, the reticu- 
lations running sparsely on to the top of the metapleure. Front and vertex 
closely but not deeply punctured, the pronotum and mesonotum more 
strongly so and with the punctures more widely separated ; the scutellum, if 
anything, more srongly punctured than the mesonotum and wth a smooth 
line down the centre. Apex of post-scutellum bluntly rounded, almost trans- 
verse. The reticulated, lateral part of the metanotum is bounded by a stout 
irregular keel. Clypeus longer than wide, opaque, finely aciculated, sparsely 
punctured, the apex rufous, with a broadly rounded shallow incision, the 
sides bluntly triangular. Basal abdominal segment, large, broadly rounded 
at the base, as wide as the 2nd segment, which Is a little wider than long ; 
the abdomen forms a longish oval and is as wide as the thorax. Female. 
Total length 13 m.m. 
The apex of the 2nd and the 3rd abaominal segments closely. somewhat 
strongly punctured, the others mure weakly punctured, the apical smooth, 
The species is larger and more strongly built than the average examples of 
O. nasideus, which it resembles in colouration and in the pale golden dense pile; 
the common species has the apex of post-scutellum tranverse, not gradually 
bluntly rounded, the pleura and metanotum are punctured, not closey dis- 
tinctly reticulated, the 2nd abdominal segment is wider compared with the 
length, the last segment is entirely fulvous, the wings are much more largely 
suffused with rufo-fulvous and the nervures and stigma are more distinctly 
fulvous ; the metanotal keel, too, is more roundly curved. 
Odynerus clavilinatus, sp.n. 
Black, densely covered with fulvous pubescence ; a small spot on the sides 
of the clypeus above, the apex with the teeth, anarrow line across the base 
of pronotum, one of the same width along the sides, the base of post-scu- 
tellum, the sides of metanotum, the line roundly dilated outwardly above, 
tubercles, a narrow line on the apex of lst abdominal segment, the apices of 
the others broadly, the whole of the last except for a triangular black mark 
in the centre of basal half, the apices of the ventral slightly more narrowly, 
the lines dilated in the middle and the last entirely, orange yellow, the under 
side of the antenne dull rufous, the scape more yellowish in tint. The basal
