27. P. pwiggarti, Bol. (BrRAzIL, San Pablo.) 
Thyrsocera puiggarit, Bolivar, An. Soc. Espafi. x, p. 354 
(1881). 
This is possibly conspecific with P. éristicula, Stal., but 
the description of the latter is so inadequate that certainty 
on this point is not possible without comparison of types. 
28. P. nigrita, Sss. (BRAZIL.) 
Thyrsocera nigrita, de Saussure, Rev. Zool. (2) xxi, p. 
111 (1869); Miss. Mex. Orth. p. 52 (1870). 
This species was described from a specimen lacking the 
abdomen and antennee, and on the strength of the different 
colour of the legs was held to be different from P. tristicula, 
Stal. A perfect example of what appears to be un- 
doubtedly this species was sent to me by Dr. Taschenberg 
of Halle and shows that the species is quite distinct from 
tristicula, the abdomen being orange-red above and below. 
In the male the supra-anal lamina is triangularly produced 
and deeply notched, the sub-genital lamina is ample and 
orbicular, bearing two short acuminate styles; the cerci 
are orange and broadly spatulate; the ante-penultimate 
tergum has the posterior margin notched in the middle, 
whilst the preceding tergum is very broadly and deeply 
emarginate, exposing nearly the whole of the following 
tergum. 
29. P. melana, Wik. (BRAZIL.) 
Pseudomops melana, Walker, |. c. p. 80, n. 16 (1868). 
Distinguished by a luteous band on the abdomen above. 
30. P. simulans, Stal. (BRAZIL) 
Pseudomops simulans, Stal. lc. p. 310 (1858). 
Thyrsocera simulans, Brunner, |. c. p. 124, n. 13 (1865). 
This species, owing to the inadequacy of the description, 
cannot be recognized with certainty; it may not even 
enter into the section of the genus with spatulate cerci. 
Pseudomops melandryoides, W1k. (l.c. p. 84, 1868) is a 
species of Phyllodromia.
