SPHINGES. 



Ilomaris palpalis Orote. 



ft 



S . — Antennae black. Head above pale sulphur yellow, palpi bright orange 

 with the tips black. Tongue black. Breast and sides of the thorax, beneath 

 the wings, pale sulphur yellow. Thorax above, covered with olivaceous or

Length of fore wings, 20 m. m. A specimen with the ticket " Gil-

 contained in the Museum of Comparative Zoology at Cambridge. 

 Allied to the Eastern H. tenuis, and diflfering from all the species 

 by the discolorous labial palpi. No perceivable reddish apical stain. 



Note. — To my previous paper on the species of Hemaris, I now 

 add the following observations which have become necessary from the 

 study of specimens kindly sent me, by Mr. Lintner, from Albany, 

 a brood of H. tenuis, raised by Mr. 0. Reinecke of Buffalo, and twelve 

 specimens of the same species from Ohio and Missouri received from 

 Dr. Hodge. I have communicated the larva of H. tenuis to Mr. Lint- 

 ner, whose attention to this group has been rewarded with such sat- 

 isfactory results, and he informs me that the specimen differs from 

 that of H. diffinis, described by himself, in the more distinct and 

 well defined ventral stripe. The general color of the larva of tenuis 

 is green, but a few brown specimens were found. The observation
