HALICTUS DUBITABILIS, sp. nov. 
H. punctatissimo affinis, sed multo minor, ¢ capite valde elon- 
gato clypeo minus producto, antennis pallidis, ? capite breviore 
clypeo minus producto, propodeo nitidiore striis basalibus brevioribus, 
distinetus. 
¢. Face very elongate, about twice as long as its greatest width 
between the eyes, antennz long, reaching, when the head is in a 
horizontal position, to about the apex of the propodeum, the joints 
of the flagellum longer than wide, slightly swollen beneath, testa- 
ceous and scarcely black even posteriorly. Mesonotum nearly dull, 
closely punctured propodeal area radiately rugose, wing nervures and 
tegule pale testaceous, legs clothed with greyish-white hairs, 
abdomen slightly shining closely and distinctly punctured on the 
Ist and 2nd segments, indefinitely on the rest, beneath with a few 
longish hairs on the discs of the segments. 
? exceedingly like a diminutive punctatissimus but the face is 
rather shorter, the clypeus not being so much produced ; the meso- 
notum is duller and rather more closely punctured, the propodeum 
more shining with more regular and shorter longitudinal striz at 
the base, beyond which the brow is smooth and shining, its apical 
margin subtruncate, abdomen punctured much as in punctatissimus. 
Long. 5 m.m. 
A species with the general facies of punctatissumus but 
much smaller, black, clothed sparingly with greyish-white 
hairs, the ¢ with the antennz beneath, the apex of the 
clypeus, the labrum, mandibles, the tibie at their base and 
apex and the tarsi pale testaceous.
