The male has the clypeus, a line on the lower side of the eye incision and 
the underside of the antennal scape bright yellow ; the yellow line on the 
apex of the third abdominal segment is widely interrupted ; the black 
marks on the basal two abdominal segments are shorter and at the apex 
do not extend to the outer edges ; there is only a narrow basal band on the 
metapleurae ; the yellow line on the apex of the second ventral is dilated 
twice in the middle and more largely triangularly at the outer edges. 
Odynerus indecor us, sp. n. 
Black, with the following parts red: the antennae except the apical 
six joints above, the mandibles except the inner edge, clypeus, a mark 
almost as wide as long, and slightly, roundly narrowed below, a broad 
line round the eye incision, the outer orbits, the line on them continued 
more narrowly round the outer edge of the vertex, prothorax, except the 
lower fourth, a broad curved line on the scuteilum, commencing laterally 
at the basal fourth ; the central apical part narrower, post-scutellum, the 
metanotum except the base and centre narrowly, an oblique wide conical 
spot on the upper basal part of the mesopleurae ; from its lower edge a 
line, widened towards the apex, runs obliquely to the lower edge of the 
pleurae ; outside this, near its centre, is a line about one-third of its length ; 
above its base is a shorter oblique line, three times longer than wide ; 
beyond the top of the last is a smaller spot. The abdomen is red with the 
following black marks : a large mark on the first, narrowed in the middle, 
the incision gradually narrowed towards the inner side, the basal black 
part narrower and broader than the apical, which has the branches sharply 
pointed, there is a large, somewhat similar mark in the centre of the 
second, the basal part clearly shorter and wider than the apical, both 
becoming gradually narrowed obliquely to the middle, a mark on the 
middle of the first ventral, narrowed at the base, becoming gradually 
widened towards the apex, the third to near the apex and the base of the 
fourth narrowly, black ; the apex of the first above, and the second and 
third all round, yellow ; wings fulvous-hyaline ; the apex fuscous- 
violaceous. Female. 
Length, 13 mm. 
Dunbrody. 
Clypeus as broad as long, closely, rather strongly punctured, the apex 
transverse ; the rest of the head more closely punctured and densely 
covered with white pubescence ; scuteilum flat ; the post-scutellum with 
a curved crenulated keel near the base, its apex broadly rounded ; sides 
of metanotum broadly rounded ; second abdominal segment hardly 
one-fourth longer than wide ; the abdominal segments are weakly, sparsely 
punctured. 
Odynerus euryspilus , sp. n. 
Black; the antennae, mandibles except on the inner side, clypeus, 
a broad mark on the centre of the lower half of the front, its upper part 
united to a line on the lower part of the eye incision by one of equal width, 
the enclosed black part being oblique, of equal width and longer than 
wide • the sides of the vertex behind, through the black on it being
