1 8 THE BLATTIDAE OF PANAMA 



angle by a minute transverse ledge with its free margin straight, on "which at its 

 inner extremity is situated the sinistral style, this style springing from a socket and 

 similar to but slightly larger than the dextral style. 



We would note that the remarkable supra-anal j^late here described is a type 

 common to a number of the related species of Anaplecta.

 paratypes.

Anaplecta sordida new species (Plate II, figure 6.) 



The present insect agrees closely with A. asema in wing venation, 

 but differs in the very dark general coloration, head with less 

 prominent borders of the ocellar areas, less acuminate tegmina and 

 proportionately less ample appendicular field of the wings. The 

 male sex of this species being unknown, we are less able to state 

 definitely its position in the genus. 



Of the other very dark species without pale tegminal margins, 

 we find from the description that, besides differing in other features, 

 A. otomia Saussure, is distinctive in the decidedly rcflexed lateral 

 margins of the pronotum and tegmina, while A. dohrniana Saus- 

 sure and Zehntner belongs to a different group, in which the wings 

 have the medio-discoidal area showing no longitudinal distal vein. 



" We find that for several of Saussure's species of the genus, determined with full satis- 

 faction in other respects, our material is distinctly smaller than the measurements given 

 by that author. This is true of our series of the Mexican azteca, the typical series of 

 which we do not believe will be found to show as much size difference from the present 

 insect as Saussure's original description (Miss. Sci. Mex., Rech. Zool., vi, p. 17, (1870)) 

 would indicate.
