36 THE BLATTIDAE OF PANAMA 



hea\y tuft of agglutinated hairs, with moderately numerous other hairs scattered 

 about laterad on the floor of the median depression; seventh and eighth segments 

 transversely narrower, exposed only narrowly along their caudal margins. 



Supra-anal plate decidedly transverse, basal width four times length, feebly tri- 

 angular with apex sub-bilobate. Cerci small, slender, tapering in distal portion 

 only to acute apex; dorsal surface flattened, much less convex than ventral surface; 

 joints strongly defined, lateral margins of each convex, particularly distad. Con- 

 cealed genitalia complex: mesad a very heavy elongate chitinous process directed 

 caudad is apparent, tapering and curving weakly to its aciculate apex, sinistrad of 

 which is a large chitinous plate; above is situated a much smaller aciculate process 

 and dextrad a plate of similar length which is rounded at its broad apex. Subgenital 

 plate asymmetrical; produced and broadly subchitinous from the caudal margin, 

 developing into heavy and chitinous plates toward the internal margins of the two 

 productions thus formed (the fused and specialized styles), the sinistral longer than 

 broad, tapering very slightly but with apex very broad and rounded; the dextral 

 heavier, more irregular, of approximately the same length but not over half as 

 broad as long; the apices of these well separated plates curving outward, as do the 

 much smaller and attingent, but analogous, plates in males of the genus Latiblattella. 

 The brief mesal portion of the distal margin of the subgenital plate between these 

 plates is produced in a minute subchitinous rounded plate with caudal surface 

 deeply concave.''^ 



Head ochraceous-buff; occiput showing very faintly four very broad vertical 

 markings of darker shade; eyes and inter-ocular-ocellar area chestnut brown, this 

 continued as a broad suffused band to near apex of labrum, with a pair of buffy 

 dashes ventrad on face. Pronotum with two broad longitudinal bars of blackish 

 chestnut brown, which broaden and diverge slightly caudad throughout their length; 

 intervening area ochraceous-buff with a faint tinge of orange, showing in very faint 

 lines and dots of darker coloration the deep-seated lyrate pattern found well 

 developed in such genera as Carihlatta Hebard, Neoblattella Shelford and others;^* 

 lateral margins translucent, ochraceous-buff. Tegmina translucent, ochraceous- 

 tawny, deepening to a line of cinnamon brown running down the humeral trunk, 

 thence straight to the apex of the tegmen, thus bisecting the costal veins, remaining 

 costal marginal portions translucent, ochraceous-buff. Wings faintly tinged with 

 prout's brown, this heavy in proximal area of costal veins and in distal portion of 

 anterior field, ulnar and axillary veins and their branches prout's brown. Abdomen 

 with dorsal surface dark brown mesad, excepting margins of segments which are 



^^ Some variation in these appendages is to be expected from their partially subchiti- 

 nous structure and decided asymmetry, while the fact that both the large plates (styles) 

 are mobile will result in their being found individually in different positions. This is 

 shown by the paratypic material at hand. 



*" A large immature specimen at hand shows that the dark bands are not developed in 

 this species until just before or when the adult condition is reached. This specimen has 

 the pronotal disk showing a lyrate pattern, broken up by twin blotches cephalad and 

 more widely separated blotches mesad, of dark brown.
