The present male differs from the Panamanian males of cro- 

 ceipennis in having the exposed portion of the wings darker, pale 

 mahogany red, the caudal margins of the fourth to seventh dorsal 

 abdominal segments weakly beaded, the ultimate dorsal ab- 

 dominal segment with minute scattered knobs distad and a con- 

 cave row of larger knobs along the caudal margin between the 

 forceps. The forceps show very slight curvature, have no distal 

 tooth on the beaded ventro-internal margin, but do have a single, 

 irregular, dorso-internal tooth as shown in the figures of *S. bor- 

 mansi. 



FORFICULIDAE 



FORFICULINAE 

 Doru lineare (Eschscholtz)

 ina, Brazil.] 



Choachi, Cundinamarca, 5900 feet, VI, 17, 1904, IX and XII, 

 1916, (from A. Maria), 2 6^, 3 9 , [Hebard Cln.]. 



These are the first specimens of lineare in the very large series 

 of nearly two hundred specimens before us, in which the wings 

 are rudimentary and entirely concealed by the tegmina. It is 

 very exceptional to find both macropterous and brachypterous 

 individuals in the same species of Doru, but three macropterous 

 examples of the normally brachypterous D. aculeatum are also 

 before us.^^ Other distinctive features make confusion with the 

 normally brachypterous D. luteipenne impossible. 



OPISTHOCOSMIINAE 

 NEOCOSMIELLA new genus 



This genus has the tegmina keeled to near the distal portion 

 and the dorsal abdominal segments neither recurved or acute 

 laterad. In other respects it appears to agree best with Cosmiella, 

 a Malaysian genus. 



The large, subrectangulate pronotum, nearly as broad as the 

 dorsal width of the tegmina, is very different from the propor- 

 tionately much smaller type found in the other American genera 

 of the Opisthocosmiinae, Dinex and Sarcinatrix, which have the 

 tegmina keeled but the sides of the abdominal segments without 

 folds. In this pronotal type it agrees with Neolohophora, which
