regions, net in hand. It may at once be recognized by the 

 figures we have given, which are taken from specimens bred 

 on the Indian River by Mr. Wittfeld. The sexes are dissimilar, 

 as the student may observe. It straggles north sparingly, even 

 as far as Canada, and is common in the Gulf States. 



(4) Erinnyis cenotrus Stoll, Plate V, Fig. 11, ?. (The 

 CEnotrus Sphinx.) 



Syn. penceus Fabricius; melancholica Grote; piperis Grote & Robin- 

 son; picta Kirby. 



The sexes in this species are dissimilar, the female being as 

 represented on our plate with light fore wings, marked with 

 dark spots and lines, while the male is prevalently quite dark on 

 the fore wings. The species may easily be recognized by the 

 black spots on the under side of the abdomen. 



(5) Erinnyis crameri Schaus, Plate V, Fig 7, ? . (Cramer's 

 Sphinx.) 



This species, which has often been confounded with the pre- 

 ceding, may easily be distinguished from it by the pale shoulder 

 lappets, the absence of black spots on the under side of the 

 abdomen, and the more evenly colored fore wings, which recall 

 those of E. meri'ance, from which it is at once distinguished by 

 the absence of the white lateral markings on the abdomen. The 

 species occurs in Florida and Texas. 



(6) Erinnyis obscura Fabricius, Plate V, Fig. 5, $ . (The 

 Obscure Sphinx.) 



Syn. rusiica Schaller; phalaris Kirby; stheno Hiibner; pallida Grote; 

 cinerosa Grote & Robinson; rhcebus Boisduval. 



This small species is well represented in our plate by a speci- 

 men which in the main conforms to the m'ost usual style of 

 marking. It can always be distinguished from E. ello, which it 

 resembles in having a dark longitudinal shade through the fore 

 wings, by its much smaller size, and by the absence of the white 

 and black lateral stripes upon the abdomen, which are character- 

 istic of the latter species. It is common in Florida. 



(7) Erinnyis domingonis Butler, Plate V, Fig. 9, ? . (The 

 Domingo Sphinx.) 



Syn. obsaira Walker {non Fabricius); festa Henry Edwards. ' 



This species, which occurs in Florida and the Antilles, may 

 be distinguished from the preceding by the darker color of the
