 1.33); III, 0.98(0.90-1.06); IV, 0.64(0.60-0.70). 



Pronotiim: Width-length ratio, 4.54(4.46-4.69) :2.18(2.02-2.37). 



Scutellum: Width-length ratio, 3.05(2.93-3.13) :2.86(2.75-3.06).

Type data. — A female specimen (Wien) bears a red type label and 

 a locality label "Brasil." This specimen was made available for 

 study. Since there is no reason to doubt that this was one of the 

 original specimens, it is here designated as lectotype. In the original 

 description two localities were cited, "Bresil" and "Nouvelle 

 Grenada." 



Specimens studied. — 6 males, 6 females. 



Venezuela: Yaracuy, G. Pittier, 1 male (USNM).

Discussion. — Little information is available on this well-marked 

 form, but for some comments on its close relationship to other species 

 see the discussion under Tominotus albicostus, new species.

 ocelli. All the others have the ocelli moderately to strongly developed 

 and conspicuous.
