124 "THE BLATTIDAE OF PANAMA 



Pronotum subdeplanate, except laterad where it is weakly de- 

 flexed, disk slightly impressed with broad and shallow latero- 

 caudal sulci appreciable; cephalic margin almost transverse, caudal 

 margin very weakly convex. Tegmina very broad, with decided 

 ridges between all of the veins except those of the anal field, dis- 

 coidal sectors longitudinal; anal sulcus distinct; oblique sulcus 

 of dextral tegmen decided. 



Male subgenital plate weakly asymmetrical. Female subgenital 

 plate valvular, the valves vertical, with proximal sulcus transverse. 



Cephalic femora with ventro-cephalic margin armed with (three) 

 widely separated, moderately heavy spines, succeeded by a row of 

 closely placed, microscopic, piliform spines, terminated by three 

 moderately heavy spines, elongate in strongly increasing ratio 

 distad. Ventro-caudal margin of cephalic femora armed with a 

 single distal spine, other ventro-caudal femoral margins unarmed, 

 but all supplied with well spaced, moderately elongate hairs. 

 Ventro-cephalic margins of median and caudal femora supplied 

 with small hairs and armed with (two and one distal) moderately 

 heavy, elongate spines. Median and caudal femora armed with a 

 moderately heavy, elongate, dorsal genicular spine. Caudal tarsi 

 very elongate, nearly as long as caudal tibia. Caudal metatarsus 

 decidedly longer than combined length of succeeding joints, pilose, 

 with ventral surface unarmed. Pulvilli absent. Minute arolia 

 present.

This insect is easily one of the most distinctive of the American 

 Corydids hitherto described. It is brusscls brown in general 

 coloration, delicately mottled with mummy brown, with a fleck 

 of this darker color mesad on each side at the caudal margin of the 

 pronotum, one proximad in the anal field at the sutural margin of 

 the tegmina, and a more conspicuous fleck of this color meso- 

 proximad in the discoidal field of the tegmina. The antennae, 

 which are much longer than the body, are mummy brown distad, 

 ochraceous-buff with an orange tinge in the proximal third, except
