primaries and the absence of the pale color on the outer margin 

 of the shoulder lappets, which is characteristic of E. obscura. It 

 is also considerably larger than E. obscura. 



There remains one other closely allied species in this group, 

 to which Cramer gave the name caicus, and which occurs 

 occasionally in Florida. The body is marked like E. ello-, the fore 

 wings are dark with longitudinal paler stripes, the secondaries 

 are red as in E. crameri, but almost wholly without the dark 

 border found in that species, it being replaced by a series 

 of dark stripes running inwardly from the border toward the 

 middle of the wing. For this species, hitherto associated 

 with the preceding in the genus Dilophonola, Rothschild & 

 Jordan have erected the genus Grammodia, upon structural 

 grounds. 



Genus PACHYLIA Walker 



This is a small genus, containing four species, of which one 

 occurs in our territory. It is not likely to be confounded with 

 anything else.

 Fig Sphinx.)

 undalifascia Butler; aterrima Bonninghausen. 



This great hawkmoth, which is very common in Central and 

 South America, occurs sparingly in Florida and Texas. 



Genus HEMEROPLANES Hubner 

 This small genus, the species of which may at once be 

 detected by the silvery spots of the fore wings, being the 

 only American genus of sphingids thus adorned, is characteris- 

 tically neotropical. It is represented in our fauna by a single 

 species. 



(i) Hemeroplanes parce Fabricius, Plate III, Fig. 8, $. 

 (The Silver-spotted Sphinx.) 



Syn. licastus Stoll; galianna Burmeister. 



The figure given on our plate is sufficiently accurate to make 

 a verbal description unnecessary. The insect occurs in southern 

 Florida in the vicinity of Biscayne Bay, and ranges thence south- 

 ward over the Antilles into South America.
