Shelf ord has pointed out that Burmeister 's sericea was the same 

 as Thunberg 's limhata, but failed to note that the latter author's 

 Blatta limhata was preoccupied.

Phoraspis brachytaenia ^^ new species. Plate XV, figiire 3. 



This insect is very closely related to P. picta (Drury) and may 

 prove to be a geographic race of that species. It may, however, be 

 ciuickly recognized by its slightly more slender appearance and 

 shorter tegminal bands. 



Type: cf; State of Santa Catharina, Brazil. [Hebard Collection, 

 Type no. 753.] 



Size smaller and form slightly more slender than in picta. In 

 other respects agreeing closely with that insect, except that the vin- 

 aceous-rufous lateral band on each of the tegmina is, both dorsal and 

 ventrad, much shorter, being abruptly terminated distinctly before 

 the meclian portion of the tegmen, while in picta it extends consid- 

 erably caudad of that point and narrows more gradually to its apex. 



Allotype: 9 ; Morretes, Parana, Brazil. [Paris Museum.] 



Agrees closely with the male sex, except in its somewhat larger 

 size. In form the sexes are similar, the present female being 

 slightly more slender than the males of picta at hand. 



General coloration shining black. Interocular space broadly 

 ochraceous-tawny, marbled with buff which shows a tinge of orange. 

 First three joints of antennae blackish brown, varying to ochraceous - 



^8 From ^paxu-Tatv(a, in allusion to the reduced band of the tegmina, which 

 is much shorter thna in the very closely allied P. picta.
