27. P. puiggarii, Bol. (Brazil, San Pablo.) 



Thyrsoccra puiggarii, Bolivar, An. Soc. Espan. x, p. 354 

 (1881). 



This is possibly conspecific with F. tristicula, Still., 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.) 



Thyrsocerct nigrita, de Saussure, Rev. Zool. (2) xxi, p. 

 Ill (1869); Miss. Mex. Orth. p. 52 (1870). 



This species was described from a specimen lacking the 

 abdomen and antennce, 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 beiug orange-red above and below. 

 In the male the supra-anal lamina is triangularly jDroduced 

 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. mclana, Wlk. (Brazil.) 



Pseudomops mclana. Walker, 1. c. p. 80, n. 16 (1868). 



Distinguished by a luteous band on the abdomen above. 



30. P. simulans, Stal. (Brazil.) 



Pseudomops simulans, Stal. 1. c. p. 310 (1858). 

 Thyrsocera simulans, Brunner, I.e. 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, Wlk. (1. c. p. 84, 1868) is a 

 species of Phyllodromia.
