GENUS IV. 

 DEILEPHILA * Ochsenheimer. 



The spiral tongue of tliis genus is considerably smaller in size than in the preceding ; the abdomen shorter, and 

 more acute at the tip ; the wings comparatively shorter, the anterior ones not having the tips produced into an acute 

 subfalcate point ; the hinder margin slightly, but regularly, rounded, and the hinder angle obtuse and not 

 rounded off as in the next genus ; the hind wings are also broader than in the latter ; the antennae are rather short, 

 and vcjy clavate at the tips, which are terminated by a hook, ending in a very slender hair ; the spiral tongue 

 is much shorter than in the preceding genus. The abdomen is only marked with interrupted dark fascife at the 

 base, the other segments having only slender pale lateral bands. The chief character of the genus, however, as 

 distinguished from the following, with which it has been generally united, consists in the peculiar form of the 

 larva, which has the sides of the body elegantly marked with pale spots of different size, and in not having the 

 anterior segments retractile ; the caudal horn is short and rugose ; and the pupa state is passed at a short 

 distance beneath the surface of the ground.

This beautiful species generally measures about three inches in the expansion of the fore wings, the ground 

 coloiu- of which is greenish brown, having a broad livid stripe, extending from the base of the inner edge to the 

 tip, the anterior portion of which has a rosy tint, but is very iiTegular in its outline, a large patch of the 

 ground colour beiug near the base, and another near the middle of the wing ; the outer margin of the wintr 

 is also bordered with a dusky or livid rosy hue ; the base of the wings has a white patch, and the inner margin 



* This generic name is derived from the Greek SeiA?;, the evening, and ipi\4w, to love, in allusion to the twilight flight of the insects ; the name 

 Smcrinthus is evidently from an^puiBos pro ix^pivBos, a thread ; but I do not perceive the alhision ; (this name is prior to Dalmau's generic 

 name Dilina, Swed. Trans. 1816 ;) and Acheroutia is a fanciful name, retaining the allusion to the specific name of the Fate, Atropos, the river 

 Acheron leading to the infernal regions.
