140 THE BLATTIDAE OF PANAMA 



caudal margin with whitish, as in C. albonervosa Rehn,i^i lateral portions transparent, 

 very faintly tinged with buckthorn brown. Tegmina and wings colored as in 

 specilliger. Dorsal surface of abdomen dull ochraceous-orange. 



In addition to the type and allotype, a female is at hand, taken 

 at Porto Bello, Panama, March 13, 1911, by A. Busck, and a 

 paratypic male, taken on the Rio Trinidad, Panama, May 5, 191 1, 

 by A. Busck. 



Subfamily PERISPHAERINAE 

 LIT0PELTISi^2 new genus 



The present genus belongs to the second section of the Perisphae-. 

 rinac, containing Stenopilema Saussure and its allies. To this 

 section also belong the American genera Colapteroblatta, Poroblatta 

 and Acroporoblatta, recently described from Colombia by the 

 author,!^^ and Miohlatta Saussure, described from Brazil. i'^^ The 

 present genus would superficially appear to be more closely related 

 to Miohlatta than to the others, and represents a unit having a 

 distinctly Panchlorine facies. Closer examination shows, how- 

 ever, that nearest relationship with Colapteroblatta exists, this 

 indicated by the general similarity of tegminal and wing form and 

 venation and limb armament. 



From the original description of the male sex of Mioblatta, we 

 find that males of Litopeltis differ in their larger size, somewhat 

 broader form, lack of pubesence, smooth vertex without carinae, 

 polished and not thickly microscopically impresso-punctate pro- 

 notum with cephalic margin showing feeble truncation, wings 

 with proportionately narrower marginal field, ulnar vein with 

 numerous incomplete branches and armed femora. 



Compared with the male type of Colapteroblatta conipsa Hebard, 

 this sex of Litopeltis is found to differ in the decidedly smaller size, 

 ocelli which are represented by poorly defined large ocellar spots, 

 more convex pronotum with lateral wings strongly declivent and 

 caudal margin more angulate and caudal metatarsus which is as 

 long as the combined length of the succeeding tarsal joints. The 

 females of these species differ similarly in size and in caudal meta- 



"' A further development of the type found in specilliger.
