Measurements {in millimeters) 



In addition to the type and allotype we have examined three 

 paratypic females bearing the same data as the type. 



W(! take pleasure in dedicating this striking species to the 

 illustrious Brazilian zoologist Dr. Herman Von Ihering, to whose 

 kindness we owe the opportunity to study the present collection. 



Sparatta clarkii Kirby 



1890. Sparatta clarkii Kirby, Journ. Linn. Soc. London, Zool., xxv, p. 52G, pi. 

 XX, figs. 8, Sa. [Tejuca, Petropolis, Constancia and Theresopolis, Brazil.] 



Hamonia, State of Santa Catharina. June 12. (Liiderwaldt; 

 under bark of tree.) One male, two females, one immature male, 

 one immature female. 



We are using this name tentatively, as we are not convinced 

 of the distinctness of this form from Serville's pelvimetra. The 

 present male material differs from the description of Serville's 

 species in the uniformly black head, pronotum, tegmina and 

 exposed portion of wings, but what value should be attached to 

 this difference is uncertain. The females are representative of 

 the form called pygidiata by Kirby, which Burr has suggested as 

 a probable synonym of clarkii. We are ciuite certain the latter 

 view is correct. The adult females agree with the male in colora- 

 tion. What relationship clarkii has to rufina Stal we do not know, 

 but here again there is strong probal)ility of more synonymy. 

 St§,l does not mention the medio-inlcriial tooth on the forceps, 

 but this may have been a pure oversight. Th(> male specimen has 

 the l(^ft branch of the forceps imperfect.
