by a sting in the neighborhood of the mouth. Then, following a 
brief delay, the wasp bit off the four pairs of legs at apparently 
one strong snip for each leg, the member being cut off at the 
next to last joint, leaving the coxal stub only. This operation. 
notwithstanding the sev eel interruptions by wandering ants, 
occupied but a minute and a half. Thereafter she grabbed her 
prey by the anterior and dorsal portion of the body; “she carried 
it beneath her, halting every now and then to fuss with her 
burden. This procedure was kept up for half an hour, when I 
captured the pair. 
Another of these wasps was carrying a spider with three uncut 
legs. This burden was borne for about 100 feet before both 
disappeared in a shallow hole in a bank. This burrow, later on 
blocked up, contained three rather short but ample cells, in enc 
of which was a more or less delegged spider with a wasp eg 
secured on the underside of its abdomen, The eggs were ease 
white, somewhat curved, and 2.35 x 0.58 mm. in dimensions. 
The second nest I located was a little way inside a rat hole in 
a bank. A short tunnel leading to a single cell contained a de- 
legged spider. I interrupted the proprietress at work, and I here 
noted that she operates like the rest of her cell-making tribe. On 
this occasion she was gathering mouthfuls of moist soil about a 
foot away from her nest to seal up the entrance to her burrow, 
using the end of the body as a plasterer. 
My observations on this insect were from March to August, 
1917. 
Pseudagenia aegina Smith. 
Length 9 mm.; thorax red, two bands on forewing. 
The nest of this pretty species is shown in Fig. 51. It was 
found well in the forest and was suspended from a bank by a 
small rootlet. It is made of rather dark soil or mud arranged 
so as to give the nest a granulated texture. It is one-celled and 
yielded a male wasp. The insect is not uncommon about the 
edge of the forest. 
Batozonus bioculatus (Bingham) 
Length 15 mm.; black; antennae, legs and wings largely orange. 
During the rainy season this conspicuous orange-winged insect 
might often be seen searching for the corpulent web- spinning 
spider Poltys sp., V with which she provisions her nest-hole. She 
is a handsome pompilid, and, apart from her gaily-colored w ings,
