42 THE BLATTIDAE OF PANAMA 



four proximal tarsal joints with pulvilli, the tarsal claws unspecial- 

 ized; with LatihIatteUa in the oblique tegminal discoidal sectors; 

 with Platylestes in the unspecialized dorsal surface of the male 

 abdomen. 



It differs signally from these genera in having the armament of 

 theventro-cephalic margins of the cephalic femora of "type A," as in 

 Supella Shelf ord. Thus the combination of characters found in 

 this genus is distinctive, but particularly is it differentiated in the 

 wing venation as discussed above. 



Generic Description. — Size very large, form moderately broad and 

 structure rather chitinous for the group. Interocular space narrow. 

 Inter-ocular-ocellar area flattened ; face transversely rather strongly 

 convex, narrow below the eyes with lateral margins moderately 

 convergent to clypeal suture. Pronotum slightly more convex than 

 is usual in the group. Tegmina and wings fully developed." 

 Tegminal discoidal sectors oblique (sixteen). Wings with costal 

 veins not enlarged distad; discoidal and ulnar veins with a great 

 number of closely placed branches (thirteen to fifteen for the ulnar 

 vein), all of the branches of the ulnar vein complete to the free 

 margin of the wing; intercalated triangle subobsolete. Dorsal 

 surface of male abdomen unspecialized. 



Ventro-cephalic margin of cephalic femora armed with a series of 

 moderately elongate heavy spines, which decrease gradually in 

 length mesad, the distal spines only slightly shorter than those 

 proximad, terminating in three heavy elongate distal spines in 

 increasing ratio. Ventro-caudal margin of cephalic femora with 

 a few (four to five) heavy elongate spines. Other femoral margins 

 well supplied with heavy elongate spines. Four proximal tarsal 

 joints supplied ventrad with large distal pulvilli; that of the third 

 caudal tarsal joint occupying almost all, of the fourth joint all, of 

 the ventral surface. Tarsal claws unspecialized. Well developed 

 arolia present. 

 Macrophyllodromia splendida new species (Plate III, figures i to 4.) 



The two dark parallel pronotal bars are very striking features in 

 this otherwise generally immaculate insect, which aside from this 

 feature, has some general superficial resemblance to NeohlattcUa 

 adspersicollis (Stal), though of much richer general coloration. 



" The female sex is unknown for this genus.
