90 THE BLATTIDAE OF PANAMA 



very distinct ocellar spots; face much flattened, polished, well supplied with short 

 white hairs which spring from microscopic pits;"'' eyes not extending below antenna! 

 sockets; lateral margins of cheeks feebly convex convergent to clypeal suture. 

 Antennae heavy and plumose in proximal two-thirds, this increasing distad, distal 

 third slender and non-plumose. Maxillary palpi short; fourth joint about three- 

 fifths as long as third, bent ventrad in narrow proximal neck, thence expanding 

 decidedly to apex; fifth joint heavy and enlarged, springing from ventral three- 

 fourths of apex of fourth joint. Pronotum with cephalic margin broadly convex, 

 caudal margin more strongly convex, lateral angles rounded at distinctly less than a 

 right angle ; surface showing broad concavities latero-cephalad. Tegmina and wings 

 fully developed, extending well beyond the abdominal apex, but not as elongate as 

 in this sex of phalerata. 



Supra-anal plate broadly produced between cereal bases, length about three- 

 quarters proximal width, margin convex. Cerci short, extending but slightly 

 beyond supra-anal plate with apex broadly rounded; dorsal surface deplanate with 

 sutures of (seven) segments weakly defined, lateral margins straight; ventral sur- 

 face with segments weakly convex and lateral margins very narrowly and weakly 

 cingulate. 



Subgenital plate broad, truncate; surface weakly convex, except laterad where it 

 is rather decidedly concave; lateral portions deep before cereal bases, with latero- 

 caudal margins more broadly rounded than those of preceding segment, thence the 

 free margin is broadly concave to beyond the cereal bases, rounding broadly into 

 the broad and very feebly convex distal portion. 



Cephalic femora with ventro-cephalic margin supplied with a fringe of moderately 

 short hairs, armed distad with two heavy elongate spines, of which the more distal 

 is the longer; ventro-caudal margin unarmed except for a smaller distal spine. 

 Ventro-cephalic margin of median and caudal femora armed with a single small but 

 stout spine and a larger distal spine. Ventro-caudal margin of median and caudal 

 femora armed in median portion with two slightly longer spines, with no distal 

 spine. Tarsi short and stout, proximal four joints unarmed, supplied with large 

 pulvilli, which occupy the entire ventral surface of each joint except the proximal 

 third of the caudal metatarsus, which is shaped into a rather strong longitudinal 

 ridge. Tarsal claws simple, asymmetrical, the cephalic claw much shorter than 

 the caudal claw, not extending beyond the apex of the large arolium. 



Head, antennae and underparts shining black, except ocellar spots and sutures of 

 mouthparts which are buffy, and abdomen which is margined laterad and caudad 

 by a broad band of ochraceous-buff (paler in the paratype, except on the subgenital 

 plate where this marginal band is tinged with ochraceous-orange toward its internal 

 margin). Pronotum black with a broad cephalic marginal band of ochraceous- 

 bufi" having an orange tinge, this broader laterad, with its caudal margins there 

 broadly convex, mcsad with median invasion of black area broad, straight, trans- 

 verse; two rounded rectangulate spots of the same pale color occur mesad at the 

 caudal margin of the pronotum, separated by an interval of the same length. 



"" The ventral surface, femora and tibiae are similarly supplied with such hairs.
