THE BLATTIDAE OF PANAMA 



Anaplecta cabimae new species (Plate II, figure 9.) 



This species is widely separated from any other here considered. 

 It shows apparent relationship to the Peruvian A. alaris Saus- 

 sure and Zehntner, differing from that species in the smaller size, 

 unicolorous tegmina and decidedly suffused wings, with different 

 venation of the medio-discoidal area. The sex of alaris can not be 

 ascertained from the original description ; the male genitalia of that 

 species will probably be found to show distinct differences from 

 those of the present species. 



In general coloration and form of tegmina similarity to A. 

 domestica Saussure and Zehntner^s is shown by the present species, 

 which however differs in the smaller size and very distinct teg- 

 minal venation. 



In general appearance this minute, straw-colored roach looks 

 much like certain species of Coleoptera. 



Type. — d"; Cabima, Panama. May 20, 1911. (A. Busck.) 

 [United States National Museum.] 



Size very small, form slender for the genus. Head scarcely longer than broad; 

 vertex evenly convex without distinct ridges over the antennal sockets; ocellar 

 spots present, very inconspicuous. Pronotum approaching oval, the caudal margin 

 showing more truncation, this margin very feebly obtuse-angulate convex; surface 

 weakly convex, with no trace of discal sulci. Tegmina extending a brief distance 

 beyond apex of abdomen, narrow; costal margin very feebly convex to near the 

 apex, where it bends more sharply to meet the sutural margin, which is almost 

 straight, apex sharply rounded; costal veins inconspicuous, not numerous (seven), 

 with a few spurious intermediate veins distad; discoidal sectors two in number 

 (the median and ulnar veins, unbranched). Wings not broad; costal veins simple, 

 subobsolete in clouded area (four to five), combining with the similar distal veinlets 

 (four to five), which also spring from the discoidal vein as it curves to meet the 

 median vein at the distal extremity of the medio-discoidal area; medio-discoidal 

 area, before this point, without transverse veinlets; appendicular field in length 

 about three-quarters that of remaining portion of wing, length equal to width.^^ 



2» Two Guatemalan females of domestica are before us. Unlike the type, these speci- 

 mens have the wings suffused, as in cabimae, but the radiate field is iridescent, not dull as 

 in that species. 



2" In this example, instead of the anal vein running to the apex of the wing along the 

 medic-longitudinal fold, an entirely different venation is found. From examination of 

 other individuals of the species, we feel satisfied that this is a remarkable individual 

 variation and not of any specific value, as conditions from the type described below to 

 the normal are found in the series of this species at hand. 



Cephalic portion of appendicular field with a vein (ulnar, rccrudescent?) which runs a 

 brief distance ol)liquely from the proximo-internal angle toward the mesal portion of the 

 free margin; caudal portion with a vein (anal, recrudescent?) which runs obliciucly from 

 the proximo-internal angle toward the mesal portion of the free margin and disappears 

 before reaching that margin, as described for alaris.
