Beneath, primaries uniform pale reddish brown, secondaries the 

 same, but paler. 



Thoracic patch bright reddish brown edged inwardly with sil- 

 very gray. Abdomen pale reddish brown. 

 D. floridana can be easily distinguished from any of its congeners 



1st. By having but three transverse lines, two of which are 

 so faint as to be scarcely distinguishable, while none of the other 

 species have less than four distinct transverse lines 2nd. By the 

 silvery edge on the thoracic patch and 3rd. by the dark color and

MACRCGLOSSA THYSBE, Fabr. 



Dnring the last spring we took several specimens of Macro- 

 glossa Uniformis. Eggs were deposited May 31st. In freedom 

 they are generally deposited singly on the underside of the leaves 

 of the" sheep-berry (Viburnum lentago). In one instance, how- 

 ever, we found 10 eggs under one leaf. 



The larvae appeared June 7th ; they passed the first moult June 

 ll-12th ; the second, June 13~14th ; the third, June 16-17th ; 

 the fourth, June 21-22d. They left their food-plant, and began 

 making cocoon June 29th. They pupated within cocoon two 

 days later, and emerged July 15th as Macroglossa Thysbe. Fabr. 



The larva in its general markings does not vary much 

 through all its history. 



The mature larva has the head deep green, large, closely sessile 

 upon the body. The head is partially retractile beneath the first 

 segment of the body. The body is nearly cylindrical, enlarging 

 moderately from the first to the fourth segments, The first seg- 

 ment has a collar above, which is edged with yellow, and under 

 which the head may be partially retracted . There is a sub-dorsal 

 line extending from the head to the caudal horn — up to maturity 

 it is yellowish, then becomes pale white. There is also an indis- 

 tinct dorsal line of yellowish changing to white. The ground 

 color of the body below the sub-dorsal line is clear deep green, 

 above a blue green, deeper bluish toward dorsal line. Spiracles 

 red spots, with a yellow dot above and below. Fore-legs red, the
