Nov., 1906.] Guatemalan Orthoptera. 13 



coarsely but shallowly punctate, as is in fact the whole face, 

 t'r.e 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 inost 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-four4;h 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- 

 t'f ires broadly rounded and strongly convergent, the apical third 

 with straight sides and evenly rounded apex, iniddle of basal 

 portion provided with two parallel lines and the sides with two 

 ciots of black; cerci of the usual form for t'is group. 



Length of body, 18 mm., of pronotum, 3.8 mm., of tegmina, 

 16 inm., of hind femora, 11 mm., of antennae, 10 mm. 



Habitat. Tlie 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. Tney were taken March 3. 

 Saussure described an insect under the nanie of Xipicera 

 pygmaea (Revue et Magasin de Zoologie, Mars 1861, p. 131.) and 

 gave as its habitat simply "Mexico." A soecimen 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 thie 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 cjuite as plainly as S. vaga Scudd. 



27. Aiiemona szte^a Sauss. There are four specimens of this very com- 



mon and wiiely dispersed locust in the collection. Tiiey were 

 taken at Mazatenango on the 3rd of February. 



28. Osmilia tolte^.i Sauss. Ever}' 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, Lij.coln.
