bay, extending over several square rods, several thousands of these 

 bees were nesting. The appearance of their burrows was the same 

 as that already described. 



To the writer these studies revealed some very interesting facts : 



First: In their natural state these bees are subjected to from 

 seven to twenty inches of rainfall during the winter. The majority 

 of these cells in the laboratory were allowed to become dry within 

 a few days after sealing and never received any moisture other 

 than that which they could get from the air in an ordinary school 

 room, yet these bees seemed to emerge normally and at approxi- 

 mately the same time as control specimens which were watered 

 several times. 



Second: Those left in broken cells, some of which were allowed 

 to lie on dry sawdust in no cell at all, emerged normally, differing in 

 this respect from Xylocopa orpifex and X. varipuncta, which were 

 subjected to the same test and which failed to emerge normally 

 when left out of contact with an enclosing cell wall. 



Third : Several larvse were left exposed during the entire season 

 in a cabinet in which were kept chemicals, including HCl, HNO3, 

 and NH4OH, and tho kept in stoppered bottles the fumes from 

 these chemicals were plainly perceptible each time I opened the 

 cabinet. These specimens all emerged normally in the spring. 



The distribution of this species as given by Lutz and Cockerell 

 in their forthcoming catalog is as follows :
