48 THE BLATTIDAE OF PANAMA 



Subgenital plate rather strongly convex, supplied with elongate scattered hairs, 

 free margins evenly and moderately convex-convergent to mesal fourth, which is 

 produced and rather strongly convex, showing a slight angulation mesad; sinistral 

 style minute, simple, cylindrical, feebly tapering to sharply rounded apex, about 

 three times as long as basal width, situated at sinistral base of median produced 

 portion; dextral style similar, except that apex is formed by two minute but stout 

 teeth and with a similar tooth at its base dextrad, this style situated at about the 

 median point on the dextral margin of the median production of the subgenital 

 plate and directed sinistro-caudad.

Agrees closely with male in ambisexual features, differing in the following re- 

 spects. Interocular space distinctly wider, only slightly narrower than width 

 between antennal bases; ocellar sjxjts smaller with area less decidedly defined. 

 Supra-anal plate similar, but less transverse, length slightly less than half proximal 

 width. Subgenital plate very short and truncate, surface convex and supplied 

 with scattered elongate hairs; free margin moderately convex laterad, transverse in 

 broad mesal portion. 



Head blackish liver brown, ocellar spots light buff, antennae prout's brown; 

 mouthparts and palpi buffy, the latter with distal segments heavily washed with 

 prout's brown. Pronotum shining, with cephalic margin narrowly*'^ and lateral 

 margins more broadly ochraceous-buff; remaining portions blackish carob brown 

 except for a large transverse elongate-ovate marking of ochraceous-buff meso- 

 caudad, this occasionally tinged with orange. Tegmina translucent, suffused with 

 prout's brown, this regularly distributed but deepest at the humeral trunk,«i' except 

 the costal margin which is broadly buffy, the transition to the darker portions of the 

 tegmina gradual. Wings transparent, very weakly tinged with prout's brown, this 

 very heavy in area of costal veins, heavy in area about the intercalated triangle, 

 weakest in the intercalated triangle. Dorsal surface and cerci prout's brown, abdo- 

 men margined narrowly laterad with ochraceous-buff. Ventral surface buffy, lat- 

 erad with coxae and proximal abdominal segments marked with brown, ventral 

 surface of abdomen often washed with ochraceous-tawny. Limbs buffy, spines 

 and tarsal joints beyond metatarsus slightly darker.

In the series the length of the caudal tarsal joints varies from 2.8 to 3 mm. 



*5 In notatus the cephalic margin of ochraceous-buff is distinctly wider mesad. 

 ^^ In notatus the humeral trunk is rich prout's brown, contrasting strongly with the 

 tegmina, which are otherwise as pale or paler than in the present species.
