82 THE BLATTIDAE OF PANAMA 



EUPHYLLODROMIA Shelford 

 1908. Euphyllodromia Shelford, Gen. Ins., 73me fasc, Orthoptera, Blattidae, 



Phyllodromiinae, p. 17. 



This name was proposed as of subgeneric value for the American 

 species previously assigned to Pseiidophyllodromia Brunner.^^o 

 We consider that it represents a unit of full generic value. 



In the subgenus were included twelve species. Genotype; 

 here selected. — [Blatta] Euphyllodromia angustata (Latreille). 



The following features are considered of generic diagnostic 

 importance. Size small, structure extremely delicate. Head very 

 broad, not covered by pronotum. Eyes well separated and prom- 

 inent, projecting laterad. Pronotum transverse, lateral margins 

 weakly deflexed, oblique sulci of disk weak. Tegmina fully devel- 

 oped in both sexes; discoidal vein angulate near apex of anal field; 

 discoidal sectors few (three), with intermediate veins, which become 

 obsolete proximad, longitudinal. Wings narrow; costal veins 

 thickened in distal half, ulnar vein with few branches (one to four, 

 the latter number due to further distal ramification of the branches), 

 intercalated triangle very narrow. Dorsal surface of male abdo- 

 men with sixth segment specialized mesad, the segments showing 

 further specialization of the latero-caudal angles. Female sub- 

 genital plate strongly cleft meso-distad. Ventro-cephalic margins 

 of cephalic femora armed with a few heavy spines, succeeded by a 

 more closely placed row of minute chaetiform spines, terminating in 

 three heavy spines, elongate in increasing ratio distad. Fourth 

 tarsal joint alone supplied with a large pulvillus which occupies its 

 entire ventral surface. ^^^ Tarsal claws unspecialized. Arolia 

 small. 



"" The genotype of that genus is Pseudophyllodromia ornata Brunner, from the Phihp- 

 pines, selected by Rehn, Trans. Am. Ent. See, xxix, p. 261, (1903). 



1" In addition to the very different tegminal and wing venation, we note from material 

 of Pseudophyllodromia laticeps (Walker) that the three proximal tarsal joints are all 

 supplied ventrad with small pulvilli, the fourth with a pulvillus as described above. 

 We regret that we have no material of the genotype of Pseudophyllodromia before us. 



Specimens of Pseudophyllodromia pulcherrima, described as an aberrant species by 

 Shelford, received from that author, show that the species represents a genus distinct 

 from that of laticeps.
