The specimens collected by Mr. Carriker are somewhat smaller than the measure- 

 ments given by Gerstaecker, but otherwise agree very well with his description of the 

 species. 



EPISCOPOTETTIX, Rehn. 

 Episcopotettix, Rehn, Trans. Am. Ent. Soc. xxix. p. 13 (1902). 



This genus, of which only a single species is known, seems to show affinities to both 

 Copiocera, Burm. (spine- characters), and Legua, Walk. (= Prorachthes, Gerst.) (vertex- 

 characters). 



l. Episcopotettix sulcirostris, Rehn. 



Episcopotettix sulcirostris, Rehn, Trans. Am. Ent. Soc. xxix. p. 13 (1902) \ 

 Hah. Mexico 1 (coll. Acad. Nat. Sci. Phil.). 



Described from a single male. A female specimen of this genus, or of a nearly 

 related one, is contained among a lot of South-American Orthoptera submitted to the 

 present writer by the Carnegie Museum of Pittsburgh for determination. Unfortunately 

 this latter specimen is without a locality-label. 



EUCOPIOCERA, gen. nov. 



Related to Copiocera, but differing from it in various respects, the chief of which are the longer and more 

 prominent vertex, the subensiform antennae, the greatly abbreviated tegmina and wings, and the non- 

 transverse prosternal spine. 



General form of body cylindrical, moderately slender. Head elongate, the front straight and greatly oblique ; 

 the vertex wide, nearly as broad as the shortest diameter of one of the elongate eyes ; the fastigium 

 gently elevated, a little more than twice as long in advance of the eyes as its greatest width, the apex 

 rounded, broadly but shallowly sulcate, and provided with a slender median and two coarser parallel 

 lateral carina? that are continuous to the occiput, where they diverge and are somewhat interrupted 

 internally by coarse punctures ; outside of these lateral carina? of the fastigium is an elongate depressed 

 area, which meets a similar area comprising the lateral foveola? ; frontal costa continuous to the clypeus, 

 very narrow above, but gradually and evenly widening below, sulcate from a point midway between the 

 base of the antenna? and apex of the fastigium ; antennas as long as the hind femora, 20- or 21-jointed, 

 the basal joints depressed. Pronotum with the sides parallel, no lateral carina?, the median carina 

 inconspicuous, present only in front and behind, anterior margin rounded, the hind edge sinuate, broadly 

 and angulately emarginate, lower lateral edges straight, the hind lobe very short, not more than one- 

 third the length of the anterior. Tegmina brachypterous, lateral, about three times as long as wide, 

 the apex subacuminate Hind femora slender, much shorter than the abdomen. The latter strongly 

 carinate ; the last ventral segment elongate, acuminate ; supra-anal plate rather small, the sides
