species being in the possession of Mr. Grote from that island. 

 Mr. A. G. Butler, however, pointed out this error in Papilio, 

 Vol. I. P. 105, and Mr. Grote, who has now seen Walker's type, 

 thus writes from London under date of Dec. 3rd, 1881 : "I have 

 carefully examined the type of CautctJiia noctiiiformis. Walker. 

 The specimen is unset, and smaller than ours from Florida; the 

 forewings very similar, but the hind wings have the yellow only 

 a patch at the base, and resting on the internal margin. The 

 wider fuscous border extends also on costal region, and the 

 yellow is paler." It cannot be but that we have here to deal 

 with an entirely different species from that described by 

 Walker, though it is somewhat extraordinary that so conspicious an 

 insect as the present should so long have escaped the observation 

 of our Florida collectors. The genus CantctJiia has been placed by 

 both Butler and Grote near Anccryx and Dilophonota. This ap- 

 pears to me to be an error, its coloration, shape of wing, ex- 

 tremely long longue, and tufted abdomen, bearing a closer re- 

 semblance to the Macroglossincc. We know nothing, however, 

 at present, of the early stages of this interesting group. 



Sphinx (Protoparce) Cingulata. n. var. decolora. 



A remarkable form, of which three examples are before me. 

 In all of these, the rose-colored shade on the base of secondaries, 

 and the sides of the abdomen, is entirely wanting. This is by no 

 means owing to fading, or to the poor condition of the specimens, 

 as two of them are absolutely fresh and perfect. In all other 

 respects, the markings are identical with those of S. Cingulata. 

 I can, therefore, only regard these examples as variations from 

 the usual type. The species is of very wide distribution, having 

 been found northward as far as Canada and southward as far as 

 Brazil. It reaches also to the extreme west of the continent, 

 and is very abundant in the Hawaian Islands. Have other ob- 

 servers noticed the extreme form now described? 



Indian River. Florida. 



Type. Coll. Hy. Edwards. B. Neumoegen. 



Dilophonota festa. n. sp. 



Size of D. obscura. Head, smoky black on crown, mingled 

 with grayish, with two white lines visible between the antennae. 

 Thorax blackish, mingled with gray — a double median line, and 

 the tegulae and space at base of the wings gray. Abdomen dull 

 iron gray, with very faint blackish dorsal double line, enclosing 

 a paler space. Sides and underside of both abdomen and 

 thorax white, thickly interspersed with brown scales. Antennas 

 with the shaft white, the pectinations fawn color, and the tip 

 pitchy-brown. Palpi, and the whole of the legs white, v/ith 

 brown scales. Primaries black, with a few grayscales intermixed, 

 except on the apex and along the internal margin, where the 

 gray predominates. The wings are deeply notched at the ter- 

 mination of the nervules, which are white and jet black, on a gray
