this specimen exhibits what appears to be a singular color pattern, 

 which might warrant description. 



General color sienna. Head with the eyes and the interspace between the 

 same wood brown; ventral aspect of head dull yellowish; antennae with the 

 first and second joints yellowish, the remainder black, the two colors gradually 

 merging. Pronotum pale yellowish, marked with two large longitudinal 

 blotches of blackish brown which flank the median bar of the basic color, these 

 being reinforced laterally by a single narrow line of the same tint; lateral lobes 

 pellucid. Tegmina with the basal field, the interspace between the ulnar vein 

 and anal sulcus, and a median space in the anal field pellucid ; anterior portion 

 of the marginal field much lighter than the general color and subpellucid. 

 Wings with the costal region infuscate. 



Pseudophyllodromia angu*tata (Latreille). 



1811, Blatta angustata Latreille, in Humboldt and Bonpland, Rec. d'Observat. 

 de Zoolog., i, p. 146, pi. xv, fig 9. [Houses of Vera Cruz.] 



Six specimens ; three males, three females; San Carlos, Costa 

 Rica. (Schild and Burgdorf.) [U. S. N. M.] 



This series is very interesting, and justifies Saussure's association 

 of venosa with this species as a synonym.* In the Biologiaf 

 Saussure and Zehutner tentatively admitted venosa as a species, 

 stating that the differential points were that venosa has the ulnar 

 vein of the wing with two branches, and the apical margin of 

 the wing is not or only very slightly infuscate, while in angus 

 lata " the wings are infuscated on the apical margin and have 

 three ulnar branches." The specimens examined have the ulnar 

 vein with two or three branches, and the apical margin is very 

 slightly or very strongly infuscate.

This species in general form resembles P. angustata (Latreille), 

 but the venation of the tegmina and coloration ot the disk of the 

 pronotum are quite different, the lormer resembling P. fasciatella 

 and the latter is similar to P. peruana. Relationship also exists 

 with P. obscura Saussure from Brazil, and P. semivitrea Brunner 

 from St. Vincent. From the former it differs in the unmarked 

 pronotum, and from the latter in the more elongate tegmina, the 

 different markings on the pronotum, and the greater interspace 

 between the eyes. No affinity exists with P. histrio Saussure or
