slender, anterior coxal cavities open, claws appendiculate, a spine on 

 middle and hind tibiae. Length 8.5 mm.; width 2.7 mm. 



Type, male, USNM 66854, from Mauricio, Guatemala, collected in 

 May 1891, by G. W. Bock, from the Knab collection. 



Remarks: With the exception of the specimens of Platymorpha 

 smaragdipennis Jacoby all the others of this genus that I have 

 examined may possibly be of one species, since in general shape 

 they are all very similar, although the variation in color and spotting 

 is considerable. Jacoby described P. variegata as having the elytra 

 black, and described as a variety of that two specimens with pale 

 fulvous elytra having a small black spot placed on the shoulder and 

 a more transversely shaped spot at the middle. The present species 

 differs from the spotted variety in being pale yellow brown, and not 

 at all reddish brown, with onl}^ a trace of a spot behind the middle on 

 each elytron. Jacoby did not mention another male character, the 

 median spine on the lower front of the face.
