146 My. J. B. Bridgman on some additions to 
supero-medial area lunate, the slanting part deeply 
grooved, with no spines; Ist segment of the abdomen 
distinctly striated, a transverse groove at the base of the 
2nd segment; this, as well as the remaining segments, 
finely reticulate, with fine scattered punctures ; apical 
segments pubescent. 
The male differs but slightly in the usual sexual 
characters ; the supero-medial area of the metathorax is 
more transverse; the groove at the base of the 2nd 
seoment is less conspicuous; and the thyridii more 
distinct. 
?. Black; base of antennz (except the basal joint), 
and 2—4 abdominal segments, entirely red; apical 
margins of the remaining segments and legs red; apical 
half of hind femora and extreme apex of hind tibie 
nigro-fuscous ; apical joint of all the tarsi black. 
$. Black; apex of 2nd segment, and base and apex of 
8—5, reddish yellow; legs fulvous; hind ones, spot on 
the coxe above, apical half of femora, tibie, and tarsi 
completely black. Length 6—7 mm. 
The striated post-petiole and black scutellum readily 
distinguish this from all the species described by 
Wesmael. 
One male and four females taken at Norwich in July 
and September. 
Dicelotus Cameroni, n.s. (Pl. VIIL., fig. 3). 
@. Nigra, pedibus rufo-flavis, coxis posterioribus 
nigris, basi antennarum subrufis. 
Antenne about half the length of the insect, basal 
joints of the flagellum moniliform ; head very shining, 
with a few minute scattered punctures. Thorax shining, 
mesothorax and scutellum with fine scattered punctures, 
metathorax very finely rugose ; superior areas 5, supero- 
medial area subtriangular with a blunt apex; posterior 
areas 8, postero-medial shehtly concave. Abdomen shin- 
ing, punctures coarser than on the thorax, but rather 
scattered. 
Black; mandibles and clypeus reddish yellow; an- 
tenne fuscous, basal portion reddish brown ; legs red, 
hind coxe black. 
One female taken at Norwich, middle of August, and I 
detected another amongst some Scotch Ichneumons 
belonging to Mr. P. Cameron.
