SUBFAMILY TRYXALINAE 21 
@tea (see Plate I, 3). .The females’ are considerably larger, of 
duller coloration, without the black lobes on the pronotum, and have 
- short and abortive tegmina and wings. There is a truly remarkable 
likeness in color and form of the females of this species to those of 
the brownish forms of Dicromorpha viridis Scudd., but they may be 
separated by the fact that in Chloealtis there is a distinct median carina 
on the vertex and the lateral carinae of the pronotum are not parallel. 
In Iowa this species is confined to woodlands or their immediate 
borders, but in Minnesota, where it is very generally distributed, it 
may be found even far out on the treeless tracts of the Red River 
Fig. 2, Normal Habitat of Chloealtis conspersa 
Valley. Its common mode of oviposition is by drilling holes in wood 
and there depositing the eggs and mucous, but on the open prairies of 
Minnesota it must adapt itself to different conditions and possibly 
oviposit even in the soil, as we have taken it in many places where 
there were no trees or even fence posts, yet the species was more 
plentiful than in the woodlands of Iowa. The following from our 
field notes, taken in Iowa, may be of interest here. 
July 26, 1909. We noted a female C. conspersa drilling in a dis- 
carded fence rail of birch which was lying on the ground. She tried 
one spot after another and after a few minutes wandered aimlessly 
upon the log making tentative examinations of the surface at intervals, 
but finally came back almost to the spot she had left and there began
