Ceratocampidae 
Genus ADELOCEPHALA Herrich-Schaeffer 
As in the preceding genus, vein 11 of the fore wing is stalked 
with veins 6-8, but the outer margin of the wing is not straight 
as in that genus, and longer than the internal margin, but it is 
convex and shorter than the inner margin. There are a number 
of species belonging to the genus, which are indigenous in 
Central and South America, but only one occurs within our 
borders. 
(i) Adelocephala bicolor Harris, Plate X, Fig. 5, $ ; Fig. 6, 
$. (The Honey-locust Moth.) 
Syn. distigma Walsh. 
The larva feeds upon the Honey-locust (Gleditschia) and the 
Kentucky Coffee-tree (Gymnocladus). It is a rather common 
insect in the valley of the Ohio, and ranges from the region of 
the Great Lakes southward to Georgia and Kansas. 
Genus SYSSPHINX Hubner 
The insects assigned to this genus by recent writers do not 
differ greatly in structure from those referred to the preceding 
genus. The principal structural differences consist in the fact 
that the antennae of the females are somewhat shorter and less 
strongly pectinated, and the abdomen is generally longer, in some 
species greatly exceeding the hind margin of the hind wings. 
The genus is well represented in Mexico and Central America. 
Only four species occur in our territory, two of which we figure. 
(1) Syssphinx albolineata Grote & Robinson, Plate X, Fig. 
7, $. (The White-lined Syssphinx.) 
Syn. raspa Boisduval. 
The figure we give is sufficient to enable the student to iden¬ 
tify this species which is common in Mexico, and also occurs in 
southern Arizona. 
(2) Syssphinx heiligbrodti Harvey, Plate XI, Fig. 14, $ . 
(Heiligbrodt’s Syssphinx.) 
This very pretty moth, which may easily be determined by 
the help of the figure we give, is not uncommon in southern 
Arizona. The caterpillar feeds, it is said, upon Grease-wood 
bushes.
