Bruner: Saltatorial Orthoptera. 41 



80. Trybliophorus modestus sp. nov. 



Quite small, a somewhat robust, and dull and plainly colored insect 

 for a member of this genus, but with the definitely produced hind 

 border of the disc of the pronotum and the strongly roughened and 

 serrated hind femora, so characteristic of other members of the genus. 



Antennae robust, pallid, or faintly testaceo-ferruginous, the basal 

 joints flattened and quite wide, gradually narrowing apically and 

 giving to them an ensiform appearance, when compared with the 

 filiform structure of these members, as they are in the remainder of 

 the described species. Head of the usual form, the eyes large and 

 prominent, the vertex narrow, about half the width of the basal 

 antennal joint; the fastigium of the vertex depressed, a- little longer 

 than, wide, linearly sulcate, but with coarse lateral walls. Frontal 

 costa plane, prominent, and broad between the antenntt, narrowly 

 sulcate and suddenly much lower below the ocellus, not quite reaching 

 the clypeus; viewed laterally broadly rounded between the antennae. 

 Front rugulose, not punctulate, as in T. octomaculattis, and its allies; 

 occiput also faintly and sparsely pitted. Pronotum rather robust and 

 punctulate, the anterior lobe subcylindrical, but little expanding 

 caudad; the posterior lobe a little expanding, hind margin of the disc 

 produced at middle, but somewhat shorter, and with the apex a little 

 more rounded than usual. Tegmina and wings somewhat abbrevi- 

 ated, about four-fifths the length of the abdomen. Hind femora 

 robust, extending beyond the tip of the abdomen nearly as much as 

 the length of the genicuke, the tibiae six-spined externally, rather 

 strongly hirsute; the first and second tarsal joints about equal in 

 length. Tip of the male abdomen acuminate and a little upturned; 

 the cerci finger-like, directed upward and a little to the rear, about 

 five times as long as wide at their base, a little narrower on their 

 apical fourth and acuminate. Prosternal spine robust, short, blunt, 

 a little transverse. 



General color pale brunneo-testaceous, sides of the head back of 

 the eyes, the upper fourth of the lateral lobes of the pronotum and 

 the disc, and the costal fields of the tegmina longitudinally vittate 

 with piceous, on the tegmina divided by a narrow pallid line. Genicu- 

 lar lunules, or arcs, and bases of the tibiae infuscated. Antennae a 

 little darker than the prevailing color of the insect. Legs concolorous, 

 the genicular lobes more pallid.
