Guatemalan Orthoptera.

coarsely but shallowly punctate, as is in fact the whole face, 
the punctures brown; occiput rather long, the eyes distant 
from the front edge of the pronotum; antennae filiform, nearly 
as long as the hind femora, the basal joint robust and green, 
the balance brown. Pronotum subcylindrical, the surface 
coarsely punctate, on the anterior lobe distantly, on the hind 
lobe rather closely; front margin rather broadly rounded, 
hind margin widely obtuse angulate, anterior half of lower edges 
obliquely truncate; transverse impressed lines continuous, pro¬ 
found, the hind lobe much shorter than the anterior one, the 
median carina distinct throughout but most apparent on hind 
lobe. Tegmina of medium width, extending a little beyond the 
apex of hind femora, their tpis rounded, with the upper portion a 
little truncate. Hind femora robust extending one-fourth their 
length beyond the tip of abdomen; hind tibiae seven-spined on 
the outside. Abdomen tapering, the last ventral segment short, 
upturned and contracted to a narrow prow-shaped projection; 
the supra-anal plate broader than long, the sides of basal two- 
thirds broadly rounded and strongly convergent, the apical third 
with straight sides and evenly rounded apex, middle of basal 
portion provided with two parallel lines and the sides with two 
dots of black; cerci of the usual form for this group. 
Length of body, 18 mm., of pronotum, 3.8 mm., of tegmina, 
16 mm., of hind femora, 11 mm., of antennae, 10 mm. 
Habitat. The single male type was taken March 11, at Puerto 
Barrios. 
25. Vi!erna aeneo-oculata DeG.(?) Two males and two females of this 
genus are at hand from Mazatenango. They were taken March 3. 
Saussure described an insect under the name of Xipicera 
pygmaea (Revue et Magasin de Zoologie, Mars 1861, p. 131.) and 
gave as its habitat simply “Mexico.” A specimen bearing Saus- 
sure's label is before me as I write. It is a Vilerna and undoubted¬ 
ly distinct from aeneo-oculata. The four Guatemalan specimens 
in the present collection are distinct from Saussure’s and are re- 
fererd with some doubt to DeGeer's species from South America. 
26. Schistocerca pyramidata Scudd.(?) There are specimens of a large 
Schistocerca in the collection from Los Amatas, which are placed 
here with some doubt. They were collected February 20. These 
insects vary from pale rufo-testaceous with scarcely any tarce of 
maculation to dark gray-brown and strongly maculate on the 
tegmina—nearly or quite as plainly as 5. vaga Scudd. 
27. Aiiemona azteca Sauss. There are four specimens of this very com¬ 
mon and widely dispersed locust in the collection. They were 
taken at Mazatenango on the 3rd of February. 
28. Osmilia tolteza Sauss. Every locality in southern Mexico and south¬ 
ward to Costa Rica, contains plenty of specimens of this locust. 
It is represented by about a score of individuals from all the lo¬ 
calities where Orthoptera were taken by Prof. Hine. 
University of Nebraska, Lincoln.
