PSEUDOMIOPTERYGINAE 



Pseudomiopteryx infuscata Saussure and Zehntncr 



1S94. Pseudortiioj)teryx infuscata Saussure and Zehntncr, Biol. Cent.-Anicr., 

 Orth., I, p. 163, pi. IX, figs. 10, 11 and 12. [c^: Presidio and Cordova, 

 Mexico; San Juan in Vera Paz, Las Mercedes, Volcan de Atitlan and Zapotc, 

 Guatemala; Chontales, Nicaragua; Bugaba, Caldera and Volcan dc Chiriqui, 

 Panama.] 



Gold Hill, Canal Zone, Panama, XI, 14, 1913, (Hebard; from 

 dead leaves on ground under bushes heavily overgrown with a 

 dense tangle of vines), 1 juv. cf . 



As we have already stated,'* infu.scafa may i^rove to be a 

 synonym, or at best a geographic race, of P. bogotensis Saussure, 

 described from Colombia. Additional series of both sexes are 

 needed before more can be said. 



MUSONIA St&l 



As has been pointed out by Kehn,^ the type of Musonia was 

 first selected by that author as surinama, and as a result, Giglio- 

 Tos' Promusonia, having surinama as genotype, is an absolute 

 synonym of Musonia. 



The species assigned by Giglio-Tos to what he incorrectly 

 considered Musonia {conspei'sa (Saussure) and major Saussure 

 and Zehntner) form a generic unit, differing from Musonia as 

 properly restricted in the features given below. To this genus 

 we give the name Macromusonia, designating the genotype as 

 Macromiisonia [Musonia\ major (Saussure and Zehntner).*^ We 

 believe that major is very probably a synonym of conspersa, but 

 until the type of that species is examined, this will be difficult to 

 decide. 



A. Size small, very elongate, juxta-ocular portions of vertex 

 only slightly convex and raised above median portion. Cephalic 

 tibiae with ventro-internal margin armed with eight spines, of 

 which the first to fourth and fifth to eighth form two series 

 regularly increasing in size distad, the fifth being decidedly

 * We have selected major as genotype, as that species alone is fully described 

 and figured.
