ish median band. This is followed by a second, quite linear, distinct, 

 undulate between the nervules on anterior, but dentate on posterior 

 wino-s. Terminal margin blackish between apical and medio-superior 

 nervules on anterior wings. 



Head with a median dark line, which separates beyond the " collar" 

 into two, margining the tegulre inwardly, these latter mixed with a few 

 lateral white scales ; two lateral brownish prothoracic spots. Abdomen 

 conical : a few lateral whitish, and below these blackish, scales at base ; 

 anal segment with a few whitish hairs, not tufted (unless by accident 

 the specimen has become deprived of the anal squammation) ; colored 

 much as the thoracic and caputal parts. Legs unicolorous with body — 

 except two reduced spurs at the extremity of the middle and hind 

 tibiae — unarmed. One S (?) specimen. Exp. 2.50 inch. Length of

Under the present generic name Hiibner has arranged four species 

 of Sphingidse figured by Cramer on Plate 216, and called by that 

 author Sphinx Pan. fig. D, *S'. Triptokmus, fig. F, S. Phito, fig. E, 

 and S. oiclus, fig. C These species seem perfectly well associated, 

 and while resembling Unyo, are slighter, slenderer; the head more pro- 

 duced and flattened. The anal segments of the males are not provided 

 with the square cut tuft of Enyo, nor are the anal segments so sud- 

 denly constricted. The anterior wings are provided with triangulate 

 albate marks, reminding one of Calliomma, though without sharing 

 the lustre of the latter genus, from which the present is very amply 

 distinct by the excavation of the external margin of the anterior wings, 

 less prominent palpi, stouter antennae, and more developed maxillae. 



The present species difi"ers from Cramer's figure of S. oiclus, too much 

 to allow of its being referred to that species. The gray color of Cra- 

 mer's figure, the different shape of the discal albate spots, the course 

 of the transverse posterior line, the punctate squammation, are very dis- 

 tinctive, while the lateral prothoracic brown spots are present in Ilemc- 

 roplanes pseudothyreus, but much reduced.
