Thy reus Abbotii. — An example taken in my garden, May 20, 1881. 

 It was at rest on a dark object, with the wings extended at right 

 angles to the body, and the abdomen curved upwards after the 

 manner of certain Pyralids. Riley has recorded the latter habit in 

 Mo. Rept, II., 79. D. S. K. 



Cypripedium acaule. — May 28th I found a blossom of the above, 

 in which a large humble-bee was imprisoned. While it had evidently 

 crawled through the fissure of the lip, the valve-like edges prevented 

 its returning, and it was too large to go out by way of the openings 

 near the stamens. D. S. K.
