40 THE BLATTIDAE OF PANAMA 



Type. — d"; Porto Bello, Panama. February i8, 191 1. (A. 

 Busck.) [United States National Museum.] 



Agrees with inornata, as described, except in the following features. Head with 

 interocular space slightly less than one-half as wide as that between the antennal 

 sockets." Tegmina and wings slightly shorter than in inornata. Wing veins 

 darkened; costal veins showing distinct distal enlargement.^'' Concealed genitalia:" 

 the mesal projecting lobe is subchitinous and the lanceolate dextral process 

 shows no velvety pile. Subgenital plate as described for inornata except for the 

 following feature; mesad at base of sinistral style, a stout cylindrical process 

 curves in an even arc, so that its apex touches the sinistral style; the brief meso- 

 caudal portion of the plate fits in tightly between the styles, its margin curled 

 inward along the dextral style. Tarsal claws of unequal length, as characteristic 

 of the genus, rather short and appreciably stouter than in iiwrnata, the shorter 

 not extending beyond the well developed arolium. 



General coloration of type buffy, tinged with buckthorn brown. Head with 

 vertex buffy with vertical blackish chestnut stripes, remaining portions, as well as 

 eyes and lateral portions of body and abdomen, shining blackish chestnut, except 

 the ocellar spots and a subocular dot on each side which are buffy. Limbs buffy. 

 Median portion of abdomen and all of subgenital plate ochraceous-tawny. Pro- 

 notum with disk ochraceous-buff, mottled with buckthorn brown, with a few sym- 

 metrically placed but weakly defined spots of prout's brown, margins of pronotum 

 transparent, very weakly tinged with buckthorn brown. Tegmina transparent, 

 weakly tinged with buckthorn brown, but more heavily so than in inornata. Wings 

 hyaline, showing a feeble iridescence, veins translucent dresden brown. 



The paratype is less intensively colored, the face having a considerable mesdl 

 buffy suffusion, the ventro-lateral portions not darkened and the pronotal markings 

 reduced. 



In the maximum recessive condition of coloration it is probable that individuals 

 of this species would show in coloration close similarity to the examples of inor- 

 nata here described.

In addition to the type, a single male paratype from Taboga 

 Island, Panama, taken June 14, 191 1, by Busck, and two immature 

 males, bearing the same data, but taken June 10 and 1 1, are before 

 us, 



^^ In the paratype even narrower, nearer one-third than one-half as wide. 



'''' This is decidedly greater than in inornata and aberrant for the genus, in the paratype 

 at hand it is not as marked. 



*^ The concealed genitalia appear to have been soft and niisshaj^en in the type, the 

 anal chamber is crushed in the paratype.
