SATURNnO^ 



Tclea polyphemus Cramer. American Silkworm. ( PI. LIX, fig. 6. ) 

 This caterpillar was taken on the ground, under hickories and 



white oaks on the forested slopes to the valley (Sta. IV, h) Aug. 26 



(No. 163). 



The larva feeds upon walnut, basswood, elm, maple, cherry, etc. 



CERATOCAMPIDiE 



atheroma regatis Fabr. Royal Walnut Moth ; Hickory Horned-devil 

 (larval name). (PI. LX, figs, i and 2.) 



This larva was found on the valley slope (Sta. IV, h) on sumac 

 Aug. 16 (No. 68) ; and on walnut Aug. 20 (No. 108). This last 

 specimen was apparently fully mature. 



The food plants of the larva are butternut, hickory, sycamore, 

 ash, and lilac. See Packard ('05, p. 130) for many figures and a 

 full description of this species. 



Basiloiia imperialis Drury. Imperial Moth. (PI. LXI, Fig. i). 



The larva of this species was found on the leaves of sassafras on 

 the forested slope to the lowland forest (Sta. IV,h) Aug. 20 (No. 

 106). It feeds upon a large number of forest trees including oak, 

 maple, wild cherry, walnut, hickory, and several conifers. 



See Packard ('05, p. 125) for figures and full descriptions of 

 this species. 



Arcthd.e 



Halisidota tcsscllaris Sm. and Abb. (PI. LXI, fig. 4.) 



These caterpillars were taken on hickory on the wooded slope to 

 the lowland (Sta. IV, b) Aug. 26 (No. 163) ; and, again, abundantly 

 (No. 168), in the upland forest (Sta. IV, a) on climbing buckwheat. 

 Polygonum convolvulus, which was entwined about a young walnut 

 or butternut. The yellow hairs and the tufts give this caterpillar a 

 striking appearance. 



I have found moths of this species abundant at Bloomington, 111. 

 The food plants are recorded as maple, oak, hazel, and button- 

 wood. Though larvae were abundant upon leaves of the climbing 

 buckwheat, I did not observe them there eating it. 



NOCTUID^ 



Autographa precationis Guen. 



The moth was taken in the open glade in the lowland forest ( Sta. 

 IV, c) Aug. 22 (No. 143). 



The larva feeds upon plantain, burdock, and dandelion.
