Elema may be found on the pine ridges of southern Missouri. 

 I have not found it here. 



I have not yet found Deidainia inscripla. The larva feeds on 

 grape. 



Everyx chcerilus is not uncommon about Curryville. There 

 are two seasonal broods. The imago is larger, but not more 

 handsome than E. myron. The larva is found here on black 

 paw ( Viburnum prunifolium) and snow-ball. Have never found 

 it on other plants. It may be easily reared in bags on snow-ball, 

 but is singularly subject to the attacks of a hymenopterous para- 

 site, so much so that few of the first brood seem to escape. 



Of all our vine feeding hawks, Everyx myron is the com- 

 monest. Larvae may be found from early Summer to late Au- 

 tumn, and are easily recognized by the swollen thoracic region, 

 small head and caudal horn, absent in the mature larva of Phi- 

 lampelus. There is a very noticeable difference in the color of 

 the imagoes. In the Summer brood (from Summer larvae in 

 June and July) many of the moths have the rust-red over both 

 wings, more or less obscuring the otherwise olive-green of the 

 Spring imagoes from Autumn larvae. 



Patient search has thus far failed to find Everyx versicolor, 

 though its food-plant, button bush, occurs along our streams. I 

 am still sanguine of success. I feel sure it is among our hawks. 

 The larvae of all our species of Everyx pupate on the surface of 

 the ground in loose cocoons of leaves, dirt and silk. 



I have taken the imago of Chcerocampa tersa at light, but have 

 failed to find the larva. It is said to feed on button-weed. Mr. 

 Ralph Sweet once found an imago fresh from the pupa, near a 

 prairie brook or slough, but a search for the food-plant proved 

 fruitless. 



In 1886 the writer collected 25 larvae of Everyx myron, 24 of 

 Ceratomia amyntor, 6 of Dolba hylceus, 40 of Paonias exccccatus, 

 20 of Daremma undulosa. In 1887, 106 larvae of Smcrimhus 

 geminatns, 24 of Hemaris thysbe, 12 of Everyx chcerilus, 6 of 

 Ttiptogon modcstus, 36 of Daremma undulosa. 15 of Hemaris 

 diffinis, 15 of Paonias exccecatus, 8 of Philampehis achemon. In 

 1897, 12 larvae of Philampehis achcmon and 13 of Smcrinthus 

 geminatus, i Cressonia juglandis, 4 Dolba hyhcus, and an un- 

 known Sphinx from trumpet creeper.
