Mr. R. Shelford's Studies of the Blattidx. 261 



are in the Hope Museum, Oxford ; one example was sent 

 to Berlin for comparison with Burmeister's type of crini- 

 cornis and was found to be quite distinct ; nor was it found 

 to agree with the other species described by Burmeister in 

 that collection. 



23. P. h'unncri, Sss. (Surinam.) 



Thyrsocera hrunncri, de Saussure, Rev. Zool. (2) xxi, p. 



Ill (1869); Miss. Mex. Orth. p. 49 (1870). 

 Thyrsocera crinicornis, var. fulva, Brunner, 1. c. p. 127 



(1865). 



I have examined the type at Paris, and in my opinion 

 the species is distinct from F. femoralis, Wlk. 



24. P. crinicornis, Burm. (Brazil, Para.) 



Thyrsocera crinicornis, Burmeister, 1. c. p. 499, n. 2 

 (1838); de Saussure, Rev. Zool. (2) xxi, p. Ill 

 (1869); Miss. Mex. Orth. p. 48 (1870); de Saussure 

 and Zehntner, 1. c. p. 33, n. 7 (1893). 



Pseudomojjs affinis. Walker, 1. c. p. 79, n. 9 (1868). 



De Saussure has identified this species coiTCctly, and 

 his description of it should render its determination easy ; 

 a drawing of an example in the Hope Museum, Oxford, 

 was sent to Berlin, and found to correspond closely with 

 Burmeister's type. 



25. P. luctuosa, Sss. (Surinam.) 



Thyrsocera luctuosa, de vSaussure, Rev. Zool. (2) xx, p. 99 

 (1868) ; Miss. Mex. Orth. p. 48, pi. 1. ff. 27, 27a (1870). 



The species is quite distinct from P. crinicornis, Burm. 



26. P. tristicula, Stal. (Brazil, Rio de Janeiro.) 



Pseudomops tristicula, Stal. Freg. Eugenie's Resa, Zool. v. 



p. 310 (1858). 

 Thyrsocera tristicula, Brunner, 1. c. p. 125, n. 17 (1865). 



An entirely black species with a testaceous vitta on each 

 side of the abdomen beneath.
