is less common. Have found the larva on tomato and potato. 

 I have neither taken the larva nor imago of M. cingulata in 

 Missouri, though I found it a common hawk at Fort Smith, 

 Ark. 



The pupa is easily distinguished by its doubly-curved tongue 

 case, so unlike that of celeus or Carolina. 



Mr. Otho C. Poling has taken cingulata at Quincy, Illinois, 

 and thinks it feeds on a solnaceous plant. Search for the 

 larva on convolvulus plants (sweet potato, bindweed, morn- 

 ing glory, etc). 



Out of twenty larvae, September, 1897, I obtained but one 

 pupa of M. Carolina. Nineteen of ithem were parasitized. I 

 have found dark brown larvte of M. Carolina only on jimsou. 



Daremma mululosa is common about Curryville, and Mr. 

 Poling has found the larvje plentiful at Quincy. 



I have found the larvje on ash in August. There is much 

 variation of color in the caterpillars. The moth looks not un- 

 like Ceratomia amyntpr, but some large males have a faint 

 grayish green tinge that gives a handsome appearance to the 

 fly. The larvte of Ceratomia ami/ntor are quite common some 

 years. Unlike the larvtc of other hawks, they have four 

 fleshy horns behind the head. The whole larva has a rough, 

 granular appearance, in perfect harmony with the harsh, 

 toothed foliage on which it feeds. Mr. Kalph Sweet took ([uite 

 half a hundred larvae of amyntor, one September, from a single 

 elm tree. 



Of Thy rem abbotii I have seen but one larva taken on grape. 

 It is probably common, though I have not found it so. Mr. 

 Poling showed me a number of pupjc of abbotii from larvae 

 taken at Quincy. The larva of Thy reus has no caudal horn. 



u^llopos titan and Amphion nesHus, as well as LepitieHia Jiavo- 

 fasciata, may be sought at early flowere, as serviceberry and 

 lilac. They fly at mid-day and are early spring species. I 

 have seen no one of them in Missouri. 



Hemaris tenuis, if it be a good species, is probably an inhab- 

 itant of Missouri. The writer has taken a moth at flowers in 

 April that answers to the description of this hawk . H. diffini^ 

 is very common. I have taken the fly at horsemint flowem 

 in May and thistle blooms in August. The larva feeds on 

 buckberry, snowberry and feverwort. H. thyabe, like diffinis, 

 hovers over early flowers and thistle blooms in the hot sun- 

 shine in August. Both diffinis and thysbe are double- brooded. 



The larva of thysbe is common on black-haw and snow-ball, 

 and may V)e known by the toothed yellow collar behind the 

 head.
