44 Trans. Acad, of St. Louis 



taining a channel three and one-half inches deep was taken 

 at Wesco, August 2, 1920. The lower portion contained 

 four cells. The plug and partitions were made of chewed 

 up vegetation, which indicates an Alcidaema bee as host 

 The host larvae all died, but the parasite emerged as an 

 adult May 18, 1921. 



Parasierola sp. [S. A. Rohwer]. A sumac twig taken 

 at Wickes, Mo. on June 30, 1918 gave forth this adult 

 parasite on the same day. Upon opening the stem, I 

 found a second and empty cocoon of the same species ; the 

 pith partitions, some pellets of bee-bread and a dried 

 larvae indicated that the host of this parasite was Cera- 

 tina calcarata. 



Parisierola cellularis Say. [S. A. Rohwer]. One was 

 found alive inside a hollow sumac stem at Wickes, April 

 23, 1920, and during the last week in May, a half-dozen 

 emerged from stems collected on that same day. 



Axima zahriskei How. [J. C. Crawford]. The host of 

 this parasite is unknown to me. Three larvae were 

 found in a hollow blackberry stem on August 14, and on 

 May 1, two adults emerged. 



Allocota thyridopterygis Riley. [S. A. Rohwer]. These 

 parasites emerged from cocoons of the bag-worm, Thy- 

 ridopteryx ephemerae/ ormis between September 11 and 

 23, 1911. These were kept in confinement, fed on molasses 

 and water, and their length of life noted. Four males 

 lived three days, twelve females lived three days, and the 

 remaining fourteen varied in longevity from four to 

 twenty-four days. 



Beetles 



Cicindela punctulata Oliv. [E. A. Schwarz] was seen 

 on June 28, feeding upon a large black ant. 



Panagaeus fasciatus Say. [E. A. Schwarz]. These 

 beetles were often found walking in the barren road at 

 Wickes, Mo., during the first half of July, 1917. Their 

 coloration and behavior were so similar to those of the
