PHASMIDZ 
No walking-sticks have been found in the Galapagos Islands. 
ACRIDIDE 
Eight native species of grasshoppers occur on the Galapagos. 
Two of these each divide into three geographic races. Of these 
species, but one is known from the mainland. That species is 
Sphingonotus fuscoirroratus (Stal.), recorded also from the 
island of Puna, in the harbor of Guayaquil, Ecuador.

The male sex of this remarkable species differs from the 
female*® in its smaller size, slightly more rugose surface, more 
convex occiput and very slightly less produced but more decli- 
vent vertex. The cerci are short, moderately stout, blunt. 
The subgenital plate is very small, conical, with apex blunt and 
somewhat transverse when seen from above. ‘The preceding 
ventral abdominal segment is broadly obtuse-angulate pro- 
duced, with apex broadly rounded and fitting into base of the 
subgenital plate. 
Coloration. The specimen before us is evidently intensively 
colored. Occiput clay-color, weakly washed with cinnamon- 
brown mesad and more heavily so laterad near the eyes; vertex 
clay-color; other portions of head clay-color, heavily and ir- 
regularly overlaid with mummy-brown, with a broad post-ocu- 
lar bar almost solidly mummy-brown. Eyes dresden-brown. 
Antenne clay-color, overlaid with mummy-brown, this very 
irregularly greater on the alternating joints, giving the an- 
tenne an irregularly annulate appearance. Pronotum dorsad, 
8 Comparison with Scudder’s apparently excellent figures is made.
