nulatus, and very long in proportion. One noted projected 
freely from the face of a cliff, curved downward and was 
about two inches long. The architect was not captured. 
O. annulatus is common in Kansas. 
Odynerus geminus Cress. 
Scott County, August 24, 1910. 
This wasp was quite common in a bare strip along a road- 
side near Scott City. A large number of males but no females 
were seen here. 
As heretofore stated, the tunnels of geminus (Pl. XV, fig. 7 
and Pl. XVI, figs. 1-4) had no mud tubes over them, and a part 
at least, if not all, of the pellets of earth are deposited within 
two or three inches from, or even closer to, the entrance of the 
hole, and this makes their nests more easily discerned than 
those of annulatus. O. geminus was not seen making its bur- 
rows in Scott County, though in Wichita County an Odynerus 
was seen starting a hole and depositing the pellets extracted 
therefrom about 14 inches away from the excavation. 
The tunnels of geminus, which were often rather closely as- 
sociated, were in barren hard soil or more or less sandy loam, 
with plenty of lagoons and ponds in the vicinity. Several were 
dug out, one of which is illustrated in Plate XV, figs. 6 and 7 in 
vertical and in horizontal section. The holes are shallow as in 
annulatus and vertical for some distance. It would appear 
that geminus utilizes its holes for a second brood, possibly en- 
larging or adding chambers to the old nest, for none of those 
examined would indicate that they were newly made. One 
nest contained refuse of old cocoons, one of the latter presum- 
ably that of a parasite. Another revealed three small pupal 
shells of a muscoidean fly and one decaying adult wasp and 
pupa, while the empty cells had been used at one time. In one 
nest, however, were two large cells, one containing two Hes- 
perid larvae and the other a Hymenopterous grub. The Lepi- 
dopterous larva was probably that of Pholisora catullus, which 
was common in the vicinity. No wasp was taken at this nest, 
but the latter was one of several tunnels constituting what ap- 
peared to be a loose colony of Odynerus geminus.
