Some Additional Bees from Prussian Amber. 
By T. D. A. Cockerelh 
I have just received from Dr. A. Tornquist three species of 
amber bees, all different from those previously described. One 
represents a new genus. 
Sophrobombns gen. nov. 
Small bees resembling Chalcohombiis, but the second transverso- 
cubital nervure absent, and the basal nervure going a considerable 
distance basad of the transverso-medial. Stigma well developed. 
Marginal cell ending rather bluntly very near to but not on costa. 
First discoidal cell shorter than marginal. Eyes naked. Mandibles 
with a convex cutting edge, without teeth. Hind basitarsus flattened, 
quadrangular, short. 
Sophrobombns fatalis sp. nov. 
J. Lengtli about 8 mm; a short, thickset bee, metallic dark 
coppery red, with very little pubescence. Yertex with very short 
fuscous plumose hair; ocelli large, in a curve; malar space about 
twice as broad as long; mandibles broadened apieally, with a convex 
cutting edge, their lower margin with long and short bristles; blades 
of maxillae long and slender; clypeus with very minute weak punctures; 
antennae very much closer together than either is to eye; scape long 
(about 1070 p), curved; second joint barrel-shaped, but its basal third 
narrower and cylindrical; third joint much longer than fourth, but 
not quite so long as second; fourth broader than long; thorax above 
with erect strongly plumose fuscous hair, twice as long (about 340 p) 
on scutellum as on mesothorax; scutellum projecting as in the allied 
genera; thorax and abdomen not or scarcely sculptured ; legs mode- 
rately clothed with fuscous hair; pulvillus large; claws with a strong 
inner tooth a little beyond the middle; hind tibiae very large and long; 
hind basitarsus quadrangular, not twice as long as broad, the outer
