Hah. Peru, 11° 3' south and 7.5° 17' west of Greenwich. 



The individual hère described is either immature or has the 

 valves of the ovipositor somewhat deformed, lienee they hâve not 

 been described. Only the type is présent. It shows a trace of a 

 median carina on the pronotum. 



Ommatolampis peruviana, sji. n. 



A somewhat larger, more robust, and at the same time more 

 strongly rugose insect than one of the preeeding (0. Ugnicola), in 

 which the liind femora are a trifle shorter and the body is rather 

 more strongly hirsute throughout. 



Head large, about as wide as the front edge of the pronotum, 

 the face but little retreating, the eyes not prominent; the vertex 

 nearly or quite as wide between the upper edge of the eyes as 

 twice the diameter of the basai antennal joint; the vertex depressed, 

 plane; the frontal costa but little produced between the antennae, 

 very coarsely punctate; antennae filiform, slender about reaching the 

 base of the hind femora. Pronotum very coarsely punctate, rugose, 

 evenly tapering, the transverse sulci profound; the anterior edge 

 broadly rounded and emarginate at center, the posterior edge trun- 

 cate; bind lobe not much more than a third the length of the ante- 

 rior one. Tegmina linear or subspatulate, not more than half Cros- 

 sing the auditoi'y aj^paratus. Hind femora moterately robust, slightly 

 surpassing the tip of the abdomen; hind tibiae somewhat undulate, 

 sevenspined on the outer margin. Prosternai spine pyramidal, acumi- 

 nate, straight. Supraanal ])late triangulär, widely sulcate at middle on 

 basai half, crossed midway by a transverse carina back of which it 

 is constricted; cerci short, bluntly pyramidal, about half the length 

 of the supraanal plate. Valves of the ovipositor short, cuneate, 

 with the apices gently hooked. 



General color above bruneo-ferruginous becoming olivaceous 

 posteriorly and below. Occiput and pronotum above marked as in 

 lignicola with strongly diverging pale lines which reach the i)oste- 

 rior edge a little below the insertion of the tegmina. Face below the 

 ocellus and above the clypeus, middle of cheeks and lower edge of
