1954] Creighton and Gregg — Cryptocerus texanus 43 
has been interpreted on the basis of probability so that 
it fits into the list. Thus his nest reported from “persim- 
mon” has been assigned to Brayodendron and that said to 
have come from a “live-oak” has been allocated to Q. 
virginiana. 
1. Quercus virginiana (live-oak) 14 colonies 
2. Quercus fusiformis (live-oak) 3 colonies 
3. Quercus stellata (deciduous oak) 2 colonies 
4. Zygia flexicaidis (Texas ebony) 3 colonies 
5. Brayodendron texanum (Mexican persimmon) 2 col- 
onies 
6. Xanthoxylum clava-herculis (prickly ash) 1 colony 
7. Celtis pallida (hackberry) 1 colony 
8. Prosopis jidiflora (mesquite) 1 colony 
Of the twenty-seven colonies listed above seventeen 
(63%) came from live-oaks. It thus appears that texanus 
definitely prefers to nest in live-oaks, although it is suffi- 
ciently flexible in its nesting habits to accept other trees 
as well. 
The size of the colony and the number of dealated queens 
present are also matters of interest. Four of the colonies 
taken by the senior author were plainly fragmentary and 
these have been omitted from the list below.
