THE EUMENIDAE 345 



ever, we found that eadi long cell had two partitions mak- 

 ing of it three cells, each of which was lined with a papery 

 substance. Most of the pupae were injured by the jar 

 when the nest fell, so that only two came to maturity and 

 emerged as adult A. tigris, on August 5 and 6, 1916. The 

 caterpillars remaining in the cells were so dried up that 

 their species was indeterminable. 



At first it seemed possible that this Eumenid had made 

 her own nest, instead of being a renter, but later we found 

 evidence of the cells having been resealed; so, in all prob- 

 ability, it had been previously occupied by one of the mud- 

 daubers. 



Mrs. Slosson finds this insect to inhabit the Alpine re- 

 gion of Mt. Washington. Banks 10 finds that it frequents 

 the flowers of Ceanothus, and Robertson records it as hav- 

 ing been taken while feeding on various flower heads. 



Two specimens of this species were taken dead from a 

 spider's web. They linger until late in the fall ; on October 

 27 several of them were out, feeding upon the few remain- 

 ing flowers of the goldenrod, at Clifton Terrace, Illinois. 



Ancistrocerus capra Sauss. [S. A. Rohwer]. 



A woody elder twig of the previous season was picked up 

 from near the ground, at Eureka, Missouri, on July 12, 



1916. It was kept indoors all winter, and on April 23-27, 



1917, four wasps of the above species and one cuckoo-bee, 

 Chrysis (Tetrachrysis) sp. } [S. A. Rohwer], emerged 

 therefrom. 



The first cell, the bottom of which was on a level with 

 the ground, was one and a quarter inches in length and 

 sealed at the top with a mud partition. The cocoon therein
