this band across the cell is nearly of the ground color of the wing ; a subapical dark 

 patch rests on the costa in four equidistant dark brown dots ; a dark spot be- 

 tween the end of the cell and the outer border very dark at the beginning extends 

 obliquely down to the outer border a little above the anal angle. Ground color of 

 fore wing with numerous cross streaks of a brighter yellowish color. Fringes concol- 

 orous with the ground color of the wing. Hind wings light gray with darker reticu- 

 larions. Underside of all the wings lighter than above and faintly reproducing the 

 markings of the upper side. Expanse of wings, 12 mm.

NOTES ON SOME DIGGER BEES.— II. 



By John B. Smith, Sc.D. 

 (Plates III-V.) 



Augochlora humeralis Patton. 



The first introduction to this species came April 4, 1898, when 

 digging out plaster casts of spider burrows. At that time Mr. Brake - 

 ley ran across occasional vertical burrows, filled at the top an inch or 

 so, but open below that and extending down fully three feet. Beyond 

 that they were lost and were looked upon as unusually deep old Col- 

 letes diggings. 



April 17th, an area 18 x 16 x 23 inches was cleared of pine needles, 

 lichens, moss and other surface debris, and about an inch and a half of 

 sand was skived off cleanly, with a large sharp trowel. In this area 13 

 round holes about one-fourth of an inch in diameter were now exposed. 

 From one of them a bee came up and was captured. It proved to be 

 Augochlora humeralis, Mr. Fox and Mr. Ashmead separately determin- 

 ing the species for me. 



Plaster was now poured into several of these holes and to Mr. 

 Brakeley's astonishment the first opening required four fluid ounces to 

 fill. The others required yet more, until in one case nine ounces 

 were needed to bring the mixture to the surface. 



April 1 8th, digging began by making a trench before the area of 

 casts, and working down an old burrow, the trench was deepened 

 from time to time until it was fully four feet down. In the first cast a 

 bee was imbedded 23 inches from the top, there was a totally different
