20 THE BLATTIDAE OF PANAMA 



The male sex of the present species is unknown, and we are con- 

 sequently unable to compare the genitalia, which we believe, from 

 examination of males of other species of the group in the unstudied 

 material before us, will be found to be very distinctive. 



Type. — 9; Porto Bello, Panama. August i8 to 20, 1916. 

 (D. E. Harrower.) [Hebard Collection, Type no. 429.] 



Size small, form slender; much as in vl. hemiscotia. Head distinctly longer than 

 broad ; ridges above antennal sockets nearly as decided as in ^ . asema ; ocellar spots 

 distinct. Pronotum much as in hemiscotia. Tegmina narrow; costal margin weakly 

 convex to the narrowly rounded apex; costal veins numerous (twelve), simple; dis- 

 coidal sectors few (five). Wings elongate, not proportionately as broad as in 

 asema, in this respect as in ^1. sordida; costal veins (nine) rather heavily clubbed 

 distad; medio-discoidal area large with four transverse veinlets, the distal veinlet 

 angulate one-third its length from median vein, sending from this angle a longi- 

 tudinal branch distad; appendicular field in length slightly more than two-fifths 

 the length of the remaining portion of the wing, length equal to width. Supra-anal 

 and subgenital plates and armament of limbs as typical for genus, described under 

 asema. 



General coloration rather pale. Head uniform dresden brown, ocellar spots 

 bufify. Pronotum with lateral margins hyaline tinged with buffy, mesal portion 

 ochraceous-buff, laterad with prout's brown sufTusions cephalad, mesad and caudad.^^ 

 Tegmina transparent, heavily tinged with yellow ocher, this strongest distad, with 

 a sharply defined, small, roughly oval, blackish chestnut brown patch meso-prox- 

 imad in the discoidal field, which sends a weak ray of the same color proximad along 

 the humeral trunk. Abdomen prout's brown; limbs warm butT; cerci buffy suf- 

 fused with prout's brown. 



Length of body, 6.7; length of pronotum, 1.7; width of pronotum, 2.3; length of 

 tegmen, 6.8; width of tegmen, 1.8 mm. 



The type is unique. 

 Anaplecta hemiscotia^* new species (Plate H, figure 8.) 



The present species is a member of the Bivittata Group, the 

 majority of the species of which have two striking dark longitu- 

 dinal markings on the pronotum ;^'-' this is also true of mexicana and 

 its nearer allies, which species are, however, larger, pale in general 

 coloration and more elongate. 



1^ These suffusions clearly analogous in the present species to the striking longitudinal 

 bands found in bivittata, analisignata and hemiscotia. 



1** From i7yui-(T/(6Tta = half dusky. 



'^ There are species, however, which should be referred to this group, which have the 

 dark pronotal markings less sharply linear. This is shown to a decided degree in A. 

 gemma, here described.
