370 On new Hymenoptera from the Khasia Hills, 
apex is more coarsely transversely striated and with a 
stouter, transverse keel which projects at the edges imto 
a stout triangular tooth. The upper part of the propleure 
smooth, the lower with curved striations on the basal half. 
Mesopleure punctured, except m the middle behind; im 
front of this it is striated. Metapleurze stoutly, obliquely 
striated. Gastrocceli shallow, smooth, transverse, black. 
The abdominal segments are covered with sbort black 
hair, except the first. 
Acanthojoppa zanthopsis, sp. 1. 
Length 13mm. ?. 
Hab. Khasia. Coll. Rothney. 
This species has a small, broader than long, areola as in 
A. nigromaculata, but it differs in the median segment not 
being marked with black and in the top of the scutellum 
being broader and more distinctly roundly incised. 
Luteous, the face, clypeus, labrum, and mandibles, except 
their teeth, pale yellow; the antenne from the 15th or 
16th joints black. Face and clypeus covered with short 
white hair. The mesonotum is darker coloured and thickly 
covered with short black hair. Apex of clypeus roundly, 
but not deeply, imcised ; the hair on the basal slope is long, 
black, and thick. The basal slope of the median segment is 
smooth and with the keels short, not reaching to the base; 
the areola small, the base rounded, the apex transverse ; the 
apical slope has the centre irregularly shagreened ; the sides 
stoutly, transversely striated. Pro- and mesopleure smooth, 
the base of the metapleuree irregularly and sparsely, the apical 
half obliquely, punctured. Wings hyaline, the apex slightly 
infuscated, the stigma testaceous. The abdomen appears 
darker coloured on the back from being thickly covered with 
short black hair. Gastrocceli shallow, deeper at the apex, 
which is wider than long and 1s aciculated. 
Acanthojoppa tinctipennis, sp. n. 
Luteous; the face, clypeus, inner orbits narrowly, the 
outer broadly below, yellow, the apex of the antenne 
broadly black ; the wings fuscous hyaline, the apical half 
darker, more violaceous in tint, smooth and shining, the 
mesonotum granular and closely covered with short black 
hair; the scutellum coarsely and closely punctured and 
thickly covered with fuscous hair; the sides strongly keeled, 
the apex above slightly depressed. Basal arez of median 
segment closely and strongly punctured ; the areola slightly 
longer than broad, its sides at the base rounded, the centre 
a little depressed; the apex slightly bent inwardly; the
