202 Remarks on the Sphingidce of Cula. 



inception of the sub-terminal line. Terminally, the wing is 

 darker ; nervules prominently tipped with exserted pale fringes. 



Secondaries, reddish-brown, withjrather faint and narrow dark 

 terminal borders ; hardly excavate before anal angle ; fringe 

 on anal angle and internal margin, whitish. 



Under-surface, brownish, shaded with reddish at the base of 

 primaries ; secondaries, more largely reddish, whitish along inter- 

 nal margin, crossed by two punctate lines. Head and thoracic 

 surface above, dark cinereous, without prominent markings. 

 Abdomen brownish cinereous, with paler hairs at the base of 

 the segments ; two darker, longitudinal, dorsal, shade lines. 



Beneath, brownish cinereous, whitish centrally ; abdomen 

 with lateral dark segmentary spots. Legs brownish ; anterior 

 tarsi paler on the outer surface, posterior pair annulated with 

 whitish scales. 



Expanse (female), 3.10 inches. Length of body, 1.60 inches. 

 Number ^Wt of Mr. Gundlach's and Prof. Poey's Colls. 



This species differs from E. melancholica, in the cinereous, not 

 brownish hue, of the upper surface of the primaries, and in the 

 shape of the secondaries. E melancholica resembles E. oeno- 

 trus and E. meriarMB in the coloration of the primaries, but the 

 costal and internal paler patches, which characterize both sexes 

 of these latter species, are absent in the former. I have not seen 

 specimens of E. obscura, Fabr. sp., but judging from Hubner's 

 acceptable figures of Erinnyis stheno, which is cited as a 

 synonym of Fabricins' species, it differs prominently in the 

 markings of the wings, and is also a somewhat smaller species 

 than E. cinerosa. 



Amphonyx cluentius has been determined by Dr. Herrich- 

 Schaffer, as occurring in Cuba, from a specimen sent by Mr, 

 Gundlach. I have seen no specimens of this species. 



I find that the generic term CEnosanda has been used by Mr, 

 Walker in 1854 in the Bombycidse, so that the Sphingid genus 

 will have to receive another name. I propose, accordingly, the 

 name Cautethia for this genus, which contains one of the
