surroiindinfi: this barn. On Soptonibcr 1 of tlio third year 

 they appoarod witliont the sli<j:litost chans^o in habit or 

 hal)itat. Tlio vegetation siirroundinp^ tlie manure-heaps 

 had meanwhile Ix'en supj)lanted l>y cinders and tlie 

 wasps liad no folia,u:e uj)on which to rest; hence many 

 paused to rest on the mannre-i)ih's. T.onir and careful 

 watching, however, revealed none of these enterine: the 

 manure for prey or hosts. A few smartweeds in blossom 

 nearby afTorded them food. By seven o'clock, all had dis- 

 appeared, and efforts to locate their sleepinj? abode were 

 futile. In this the tliird year also their dissemination 

 over the field was nil. A visit to the area on October G 

 showed that they were not to be found so late in the 

 season. 



Scoiia nohilitata Fabr. [S. A. Rohwer]. Taken on tlie 

 flowers of buck-brush at Wesco, Auj^fust 1, 1920. 



Elis atriventris Galian. [S. A. Rohwer]. A dead speci- 

 men of this wasp was lyini:^ on the hot sand at Tiake View, 

 Kansas, July 29. 



Elis quinq^iecincta Fal>r. [S. A. Roliwer]. WhiK' i 

 have made observations on the .i;re,2:arious sleepinu: 

 hal/its of the males,* I have found notliin.c; on the habits 

 of the females cxceptiniif on one occasion in a dirt road, 

 where one made three attempts to ^et under some clods 

 of dirt, and under the last one she remained hidden for 

 some time. Since this species is supposed to stini? and 

 oviposit in the larva of may-beetles, this may indicate 

 that she was searchin.i,' for prey. This species was seen 

 feedin.u: upon the flowers of ^felilotus alba. ( )n another 

 occasion, on July 2(), a ji:rou]) of a dozen males and one 

 female was found sippin.i!: the nectar of these flowers. 



Elis interrupia Say. | S. A. Ixoliwer]. This species was 

 also on tlie buck-brush llowers at Wesco, Aui^ust 1, 1920. 

 Tipliia vulgaris Rob. fS. A. liohwer]. This medium- 

 sized wasp was taken from the mouth of a roliber-fly,
