68 Trans. Acad, of St. Louis 



sp. [N. Banks]. On the night of September 9, a moth, 

 Acronycta sp. [Heinrich] was also taken from a centi- 

 pede's mouth. Again, on May 26, one was enjoying a 

 moth, Diacrisia virginica Fab. [H. G. Dyar] which it had 

 captured in the darkness. An incision had been made in 

 the victim 's body wall, at the side, and the soft abdominal 

 contents devoured. They are even canibalistic. I once 

 placed two of them in a jar; the next morning, there was 

 only one, the larger, and a few scraps of legs and skin of 

 the other. 



Polydesmus serratus Say [R. V. Chamberlin]. Under 

 the bark of a rotten log May 20, 1916 we found the neat 

 mud nest and eggs of this species, with the mother's body 

 coiled carefully around them. 



ParajiUus venustrus Wood. [R. V. Chamberlin]. This 

 milliped was found feeding on the flower cluster of some 

 white-flowered composite by the roadside, October 7, 

 1916. 



Spiders 



Theridium tepidariorum Koch. [N. Banks]. A large 

 spider, Phidippus audax Htz. [N. Banks] became en- 

 tangled in the web of the little spider above. The small 

 spider quickly threw a web about the larger one and 

 easily made him his victim — a veritable game of David 

 and Golioth. 



Misumena (Runcinia) oleatoria 5. [J. H. Emerton]. 

 Feeding on grasshopper, (PI. VI fig. 7, p=prey) Septem- 

 ber 10, 1918. 



Runcinia oleatoria Htz. [C. R. Shoemaker]. A little 

 Hymenopteron seemed to be asleep on the flowers of a 

 goldenrod. When I picked it up, I was surprised to find 

 that it was held fast by this yellow spider, whose color 

 afforded him such good protection in his hunting-ground, 

 the flower, that even my practiced eye did not notice him. 



Misumena asperata. [J. H. Emerton]. One often finds, 

 in the fields or by tho railroad-track, sumac twigs, with
