Halictus dubitabilis, sp. nov. 



H. punctatissimo affinis, seel multo minor, ^ capite valde elon- 

 gate clypeo minus producto, antennis pallidis, $ capite breviore 

 clypeo minus producto, propodeo nitidiore striis basalibus brevioribus, 

 distinctus. 



^. Face very elongate, about twice as long as its greatest width 

 between the eyes, antennae 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 punctvired propodeal area radiately rugose, wing nervures and 

 tegulse pale testaceous, legs clothed with greyish-white hairs, 

 abdomen slightly shining closely and distinctly punctured on the 

 1st and 2nd segments, indefinitely on the rest, beneath with a few 

 longish hairs on the discs of the segments. 



9 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 striaj 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 punctatissimus but 

 much smaller, black, clothed sparingly with greyish-white 

 hairs, the $ with the antennae beneath, the apex of the 

 clypeus, the labrum, mandibles, the tibiae at their base and 

 apex and the tarsi pale testaceous.
