^ Trans. Acad, of St. Louis 



over tlio vo.irotation near Crcvo rocur Lake aiul near the 

 Meramec Hivcr at Moselle. One male specimen of S. 

 scarva emer/jfetl from a cocoon of SccUphroyi carvicnta- 

 r'utm on June If). It was i)lace(l in a vial where, in a few 

 (lays, it broke uj) with its jaws much of the cork stopper. 

 It was then placed in a ca«^e with su^Mr-water and fruit, 

 where it lived for twenty-five days. 



Priocnvmis ncbulosus Dahl. ( S. A. Holiwer]. In a road 

 sparsely covered with ^rass, this Pomi)ilid was actively 

 chasin/i: a spider, but the wasp in her chase encountered 

 a spider's web in the ^rass; she paused in her (piest and 

 spent several seconds searchin-j^ it, and thus lost her 

 quarry. 



Priocnemis nothus Ores. [S. A. Koliwer]. One specimen 

 was taken on the sunny baseball field on September 17. 



Priocnemis nigripes Ores. [S. A. Kohwer]. We have 

 twice found this wasp out walkiujuf about on the ground, 

 once in an open field in St. Louis and a.ii^ain on the sandy 

 ground near the river front in Kansas. They moved 

 nervously, and were poking their heads enquiringly into 

 every crevice and under sticks and leaves. From this 

 conduct we judged they were foraging. 



Priocnemis pompilus Cress. fS. A. Rohwer]. Two in- 

 dividuals were seen foraging on a clay bank in St. Louis 

 on June 20, 19LS. They were eagerly scrambling under 

 clods and nervously tumbling into crevices. After many 

 such adventures, one brought a small si)ider out of a 

 crevice. She carried it a short distance, exjjlored about 

 the region for a few iniiiutes, then returned to the spider. 

 This performance she repeated three times, then she 

 carried the spider into one of the crevices. Three quar- 

 ters of an iiour elapsed and she did not reap])ear. 



Cryptocheilus unifasciatus Say. L^- -^- Hohwer]. On 

 August 31, at Wickes, iMo., this wasj) was seen dragging 

 a large spider by the mandibles across a rough road and 

 over a grassy area, traveling with ease and rajjidity. 

 The spider was limp and apparently dead.
