Supra-anal lamina slightly produced ; sub-genital lamina large, 

 siJoon-shaped ; cerci moderate. 



The genus bears the same relation to Anapleda, that 

 Pscudcdohia does to TlicgaiwpUryx.

 extremities swollen, medio-discal field crossed by eight transverse 

 venulse, ulnar vein with six branches, apical area broader than long,

II. The 'genera Pseudomops, Serv., and Thyrsocera, 

 Burm., of the suh-fam. Phyllodromiin.<e. 



There has been considerable confusion regarding those 

 species of Phyllodromiinse with incrassated antenna; and 

 angulate ulnar veins in the tegmina. The steps whereby 

 this confusion has grown may be summarized shortly as 

 follows : — 



The genus Pseudomoiis was founded in 1831 by Serville 

 for the reception of the Blatta oblongata of Linn^us, though 

 whether Serville's determination of the Linngean species is 

 correct is not certain. Burmeister in 1838 included in 

 his genus Thi/rsoccra the species spcdahilis, crinicornis, 

 cinda, afjinis, flavvpcs, laticornis (Perty), histrio, oblongata 

 (Linn.), anniUicornis and hirticornis ', of these ten species 

 eight are Neotropical, two {spedabilis and histrio) are 

 Oriental ; spedabilis must be selected as the type of the 

 genus. Brunner, de Saussure, and other authors have 

 ignored Serville's name Pseudomops and have employed 

 Thyrsocera instead; however de Saussure in 1893 created the 

 genus Hemithyrsoccra for those Oriental species with a 

 triangular apical triangle to the wings and with a simple or 

 bifurcated vena ulnaris alarum ; of this genus Jncimda is
