38 THE BLATTIDAE OF PANAMA 



Abdomen with proximal dorsal segments unspecialized; sixth with a semicircular 

 mesal area, formed cephalad by a convex ridge and laterad by the weakly convex 

 margins of very suddenly and deeply impressed longitudinal areas, caudad of the 

 cephalic ridge is a narrow, transverse, feebly obtuse-angulate plate, with free caudal 

 margin supplied with a few hairs, caudad of this the median portion of the special- 

 ized area is raised in a large blunt process, with lateral margins concave and diver- 

 gent caudad and dorsal surface clothed with a heavy tuft of hairs radiating cephalad, 

 caudad of this the narrow distal portion of the segment is subchitinous in texture, 

 the caudal margin transverse, but with latero-caudal angles moderately acute- 

 angulate produced, with apex bluntly rounded; seventh segment longitudinally 

 brief, transversely moderately constricted; eighth segment much the same, but 

 with caudal margin sinuous. 



Supra-anal plate transverse, triangularly weakly produced, with apex broad and 

 briefly bilobate. Concealed genitalia: soft integument almost completely fills the 

 anal chamber, from which projects mesad a short, flattened, chitinous lobe, with 

 surface microscopically shagreenous and with disto-dextral angle produced in a 

 short spine, which curves feebly sinistrad at its sharp apex; ventrad of this process 

 the integument is produced in a straight, elongate process, tapering evenly to the 

 acute apex, with dextral margin subchitinous. Dextrad, beneath the dextral 

 cercus, an elongate, lanceolate, chitinous process extends meso-caudad, with sur- 

 face heavily clothed with a microscopic velvety pile. Subgenital plate not large, 

 somewhat asymmetrical ; brief lateral margins convex to bases of heavy, elongate, 

 inset styles, between which the brief and delicate meso-caudal portion of the plate 

 is deplanate, weakly produced with free margin weakly convex. Styles stout, 

 elongate, flattened cylindrical, convergent, with immediate apices rounded and 

 curved outward and supplied with a few hairs; dextral style considerably larger 

 than sinistral. Mesad, at base of sinistral style, a moderately stout, flattened 

 cylindrical process curves mesad, thence nearly straight caudad, with immediate 

 apex rounded, not enlarged and curving sinistrad, the median portion with dorsal 

 surface feebly convex and ventral surface deplanate, the ventral margins thus 

 formed microscopically serrate. Limbs and their armament, character of pulvilli 

 and arolia, typical for the genus." Tarsal claws of unequal length, as characteristic 

 for the genus, elongate and slender, the shorter extending well beyond the moder- 

 ately well developed arolium.

Agrees with type, except in the following features. Form decidedly broader, 

 pronotum more ample. Tegmina and wings distinctly less elongate, but extending 

 well beyond the cereal apices. Dorsal surface of abdomen unspecialized. Supra-

 Costa Rica, as these were the ports at which fruit had last been loaded.
