evenly arched, as in the genus Acrolophitus, lateral carina} continuous, 

 increasing in size backwards, and forming overhanging blunt walls to 

 the lateral lobes; posterior extremity acute-angled, with the tip up- 

 turned and strongly marginate. Tegmiua lanceolate-ovate, in the 

 female about half as long, and in the male only a trifle shorter than the 

 abilomeu; wings shorter than the tegmiua, the humeral held very nar- 

 row, the axillary equal to the post-axillary or radial field and bordered 

 with very heavy veins, like this portion of the wing in Rhomalea and 

 Ta>niopoda, and like these are evidently used as musical organs. 



General color, dirty grayish-white, with a slight rusty tinge to the 

 sides of the pronotnm and thorax. Lower half of tegmiua brown. 

 Inner face and lower sulcus of posterior femora black nearly to the 

 knee; inner edge of posterior tibiie bright vermilion, outside grayish- 

 white. Carime of face, pronotum, and posterior femora flecked with 

 dark brown and black. Tips of antenna? infuscated, remainder gray- 

 ish. Spines of posterior tibia; testaceo-cinereous iu the middle, their 

 bases and tips black.

Sub-family TRYXALIN-S3. 

 Ochrilidia (?) crenulata sp. nov. 



Related to 0. occidentalis (Stenobothrus occidentalis Thos.), from which 

 it differs in its smaller size, shorter occiput, and in its markings. 



Occiput rather short and slightly rounding ; the vertex between the 

 eyes about as wide as the length of the basal autennal joint, the front 

 margined by a bluut carina, forming at the fastigium , a right angle, with 

 the apex, gently rounded; lateral foveohe missing; frontal costa prom- 

 inent above, where it is very narrow, widening evenly below, sulcate 

 throughout, the literal walls sharp. Eyes pyriform, not prominent. 

 Face straight, very oblique. Pronotum short, nearly as broad as long, 

 the lateral carina? greatly bowed, faint; median carina visible through- 

 out, severed about the middle by the last transverse impressed line ; 

 anterior edge slightly ascending upou the occiput; posterior edge 

 broadly rounded. Tegmina narrow, the anterior edge bowed, the pos- 

 terior edge straight ; the veins of the disk not uniting and forming colls. 

 Posterior femora slender, in the female just reaching, but in the male 

 surpassing, the tip of the abdomen about one-third of their length. In- 

 terior apical spines of the posterior tibiie fully twice as long as those on 

 the outside, the lower one much the longest. Antenna; long, with the 

 basal joints somewhat flattened, and the apex acuminate. 



General color light testaceous, striped, and marked with brown. 

 Frontal costa and a quite broad median liue reaching from the fas-
