 recognisable. 



The genus is dedicated to Mr. Harold W. B. Moore, formerly of the Guiana 

 Museum, who has reared most of the parasite Hymenoptera described in 

 these papers. 



Moorella fulviceps, sp. n. 



Black, the head fulvous, the pronotum of a paler fulvous colour, the pro- 

 pleurae pale testaceous, the base and apex of the abdomen, the former on the 

 basal segment all round and the latter much more narrowly on the apical 

 white segment ; antennae testaceous, the scape paler, more yellowish in colour ; 

 anterior legs whitish, the coxae and trochanters of a clearer white, the middle 

 pair fuscous, the hinder black, the apical three-fourths of the 1st joint of the 

 tarsi, and the whole of the 2nd to 4th white, the 5th fuscous. Wings hyaline, 

 the submarginal nervure fuscous, the others black, a large fuscous cloud, 

 commencing at the stigma where it is narrowed and extends to the hinder- 

 margin of the wing ; the base is almost straight, the apex broadly rounded. 

 Co-vered with a white microscopic pile ; smooth and shining, the apex of the 

 mesonotum and the scutellum finely, closely punctured; the latter with a few 

 punctures in the centre. Mesopleurae opaque, bare, almost aciculated. Female. 

 Length, 1*5 mm. 



The hind tarsi are one third of the length of the tibia?. The wings are 

 pilose and distinctly ciliated round the outer margin.

Phlebopenes albopilosellus, sp. n. 



Metallic green, the lateral lobes of the mesonotum broadly dark purple, 

 the back of the abdomen broadly of a brighter purple, the centre of the front 

 below, the lower lateral part of the face, a line on the inner side of malar space, 

 the basal half of the scutellum, the parts bordering it, post-scutellum, the sides 

 of metanotum and a large irregular mark down the middle of the mesopleura- 

 dark indigo-blue the mesonotum in front, the pleurae, mesosternum and sides 

 of abdomen with brassy tints ; legs black, the femora and more particularly 

 the hinder, green, the hind tibiae at the base with a white ring, as long as the 

 hind spurs. Wings hyaline, the centre of the anterior with fuscous streaks, 

 the nervures black. Female. Length, 11 mm. terebra, 24 mm. 



Antennal scape dark green, narrowed to a point in the centre below, 

 distinctly keeled there. Face raised slightly in the centre, bordered by shal- 

 low furrows which converge slightly above ; finely, closely punctured, the sides 

 irregularly transversely striated. Front and vertex finely closely punctured. 

 The raised central lobe of the mesonotum is finely closely transversely striated; 

 the raised, basal central lobe is more strongly striated, especially on the sides 

 at the base ; the scutellum finely striated, becoming stronger towards the 

 apex ; the outer edge of the mesonotum is raised into a keel, inside of which
