244 SELECTED NOTES FROM 



Of the short-tongued bees without polliniferous hairs on the 

 posterior tibise there are only two famiHes : — (i) Frosopis, having 

 two submarginal cells to the wings ; and (2) Sphecodes, having 

 three submarginal cells. The second division, or long-tongued 

 bees, are also divided into those without polliniferous organs and 

 those with them. 



Of those without polliniferous organs two families have two 

 submarginal cells to the wings : — (i) Stelis, where the abdomen 

 is rounded at the apex ; (2) Coeiioxys, where the apex of the 

 abdomen is conical ; and four families have three submarginal 

 cells : — (i) Nomada^ with lanceolate abdomen ; (2) Epeohis^ 

 abdomen sub-truncate at the base, and obovate, with glabrous 

 thorax ; (3) Melecta^ abdomen subconical, thorax hirsute ; and 

 (4) Apathus, wh-Qxe the entire body is densely hairy. 



All the other families of the long-tongued bees have pollin- 

 iferous organs, and may be thus divided : — Pollen conveyed on 

 the venter, two submarginal cells, abdomen subclavate, first three 

 joints of labial palpi continuous, terminal joint inserted before 

 apex of third, (i) Chelostoma ; (2) Heriades differs in having 

 the first two joints of labial palpi continuous, and the two last 

 inserted before the apex of the second ; Osmia has the abdomen 

 obovate and rounded at apex ; Megachile has the abdomen 

 truncated at the base, segments slightly constricted, and not 

 spotted with colour ; Anthidtu?n, the segments are not constricted 

 and are covered with yellow. 



Next come those carrying pollen on their posterior legs. 

 Two families have two submarginal cells : — (i) Pantirgus^ with 

 lanceolate abdomen, clavate antennae, and posterior legs, covered 

 with long hair ; and (2) Eucera, with obovate abdomen, filiform 

 antennae, and posterior legs, covered with short dense hair. 



The rest of the bees have three submardnal cells to the 

 wings : — (i) Anthophora, short dense hair on the posterior tibiae 

 externally, abdomen obovate, first joint of labial palpi twice as 

 long as the second ; (2) Saropoda, like AnthopJiora, excepting 

 that the abdomen is sub-rotund, and that the first joint of the 

 labial palpi is six times as long as the rest ; Ceratina, with long 

 but loose hair on the entire posterior tibiae externally and inter- 

 nally, the abdomen being sub-clavate ; Boinbus, curved hair, 

 fringing the edge only of the posterior tibiae, the centre glabrous, 

 the body densely hirsute, and spurs to all the tibiae ; and, lastly, 

 Apis^ where the body is sub-pubescent and the posterior tibiae 

 have no spurs. 



The above is epitomised from " Shuckard's British Bees," a 

 work, perhaps, not without mistakes, but one that has most helped 

 me to the knowledge which I possess of British bees.
