[Vol. VII, No. L 
Fastigium of the vertex elongate, triangular, with a moderate¬ 
ly broad but shallow median longitudinal sulcus, the apex slightly 
acuminate; frontal costa rather deeply sulcate, widened above 
the antennae, nearly equal below, the face unicolorous, impunc- 
tate, strongly oblique; antennae only a trifle longer than the head 
and pronotum taken together; eyes moderately prominent, a 
little less divergent than in the males of A. chlorizans, about 
twice the length of that portion of the cheeks below them. Pro¬ 
notum subcylindrical, rather closely and finely punctate, much 
more closely so in front and on the hind lobe, the latter with a 
prominent median carina and short shoulders, about four-fifths 
as long as on the anterior lobes. Tegmina narrow, extending 
one-fifth of their length beyond the apex of the abdomen. Hind 
femora slender, smooth, as long as the abdomen. The latter 
graceful, tapering, the last ventral segment short and provided 
with a lateral blunt tooth at each side, the center prolonged into 
a short boot-like projection in which the toe is directed to the 
rear. Hind tibiae slender, the lateral carinae poorly developed 
as compared with some of the other species of the genus. Pros- 
ternal spine slender, straight, the apex evenly rounded. 
General color pale grass-green above, yellowish white below. 
Wings caerulean, the dorsum of the abdomen leaden gray. An¬ 
tennae ferriginous, clypeus, labrum, tip of last ventral segment 
and hind tarsi pink. 
Length of body, 22 mm., of antennae, 7 mm., of pronotum, 
3.65 mm., of tegmina, 20 mm., of hind femora, 11.5 mm. 
Habitat. A single male from San Jose, February 5. 
This genus appears to be represented by quite a number of 
species—a dozen or more—when we consider the two Americas. 
They fall into two well defined sections or possibly into distinct 
genera. 
22. Arnilia sp. The collection also contains a single female specimen of 
what appears to be a second species of Arnilia', but, since there 
are at least a half-dozen distinct species of similar size at hand 
as I write, it is difficult to definitely place it with certainty. The 
characters, so far as observed, are more pronounced in the males, 
and until I have had an opprotunity to critically study the dozen 
or more species of the genus of which I have specimens no attempt 
will be made to determine the individual just referred to. It was 
taken February 6, at Amatitlan. 
23. Inusia obscura (Thumb.) (?) Two pairs of a slender locust taken at 
Los Amates, February 25-27, are referred with some doubt to 
Thunberg’s Acridium obscurum. Whether they are that insect 
or not, they belong to Giglio-Tos’ genus Inusia which contains 
two or three representatives in tropical America. 
24. Cornops scudderi n. sp. A moderately robust, medium sized, grass- 
green and testaceous insect with a broad piceous band on each 
side which extends from the back edge of the eyes along the upper 
half of the pronotum and pleura and is bordered below by one 
of greenish yellow. The costal margin and disc of the tegmina 
are dark brown or fuscous. 
Head somewhat wider than the front edge of the pronotum; 
the eyes a little prominent and strongly divergent, a trifle longer 
than that portion of the cheeks below them; vertex nearly as 
broad as the frontal costa between the antennae, rather deeply 
sulcate to the tip of the fastigium. the latter a little wider than 
long, somewhat depressed and blunt in front; frontal costa 
prominent, a little widest above the ocellus, gently sulcate,
