NOTES AND OBSERVATIONS. 



The Crimson Augochlora Bees. — The species of Augochlora, 

 closely related to Halictus, are of various colours, but usually brilliant 

 green. There is, however, a little group in which the whole body is 

 crimson or brilliant copper-red. A study of these peculiarly coloured 

 forms brings out the fact that they belong to three entirely distinct 

 sections or subgenera, and hence must represent quite independent 

 developments of essentially the same peculiar coloration. The follow- 

 ing table will separate them : 



Mesothorax very strongly punctured ; abdominal seg- 

 ments fringed or vibrissate (Mexico) . . flammea Sm. 

 Mesothorax very minutely punctured ; abdominal seg- 

 ments not vibrissate ..... 

 Mesothorax dull ; basal area of metathorax covered 

 with radiating striae ; hind spur of hind leg minutely 

 denticulate (Dominica, West Indies).. ignifera Crawf. 



Mesothorax shining ; basal area not covered with 

 radiating stria>, ; hind spur with long, stout spines 

 (Mexico and Guatemala) . . . fulgur (Vachal) 



The Guatemala record of A. fulgur is based on a specimen in the 

 U.S. National Museum, collected by Schwarz and Barber, April 20th, 

 at Cacao, Trece Aguas, Alta Vera Paz. It differs a little from 

 Vachal's description, in that the hair on the abdomen is fulvous. 

 Halictus anthrax Vachal and Augochlora aureocuprea Friese both 

 appear to be synonyms of A. flammea. — T. D. A. Cockerell ;
