underneath the above markings of the wing are very indistinct ; the 

 secondaries are rose-colour, paler at the costal and posterior margins ; 

 underneath they are dusky-cinereous, with a whitish band coinciding with 

 that of the primaries, a transverse series of cr2scents and a dentated 

 brownish band, all rather indistinct ; but the most conspicuous character 

 of the secondaries is a large eyelet situated at the anal angle, consisting 

 of a black pupil, nearly but not quite surrounded by a blue iris, and situ- 

 ated in a black triangular spot or atmosphere, which extends to the anal 

 angle, and is surmounted bv sou blue scales ; the abdomen above is 

 dusky ash-coloured. 



This insect appears to be the American representative of .S. oceilatus^ 

 from which, however, it differs considerably. It comes very near to S. 

 geminatus (Say Am. Ent. i., /. xii.,) but in that the eyelet has two blue 

 pupils. 



423. Deilephila intermedia Kirby. — Expansion of wings 23^ 

 inches. Taken in North America. 



This species is intermediate between D. Eup/iorbice Sind D. Galii, which 

 last it most resembles, but the anterior portion of the mesal stripe of the 

 primary wings is pale rose-colour ; the fringe of their inner margin, and 

 of the posterior of the secondaries is white ; there is no series of white 

 dots on the back of the abdomen and the ventral segments are fringed at 

 the apex with white hairs. This description was taken from an old speci- 

 men apparently somewhat faded. 



[Is probably identical with D. Cliamcencrii Harris, a common species 

 in Canada.]
