Mr. A. G. Butler on new Blattarige. 



Geomphadorhina, Brunner v. Wattenwjl. 



Of this extraordinary genus its author gives the following 

 diagnosis in his analytical table of genera of Perisphseridaj, 

 "Mares alati (?) ; femino3 apterte ;" but upon referring to his 

 description of the same genus founded upon a male forwarded 

 to him by M. Dohrn we find this diagnosis directly contradicted 

 in the following words : — " II a tous le(s) caract^res du genre 

 precedent [Homalodemas] , a I'exception de I'absence totale des 

 organes du vol et des tubercules du pronotum developpes en 

 forme de cornes." An examination of the figures of this 

 singular species will convince any one that the latter is the 

 correct description.

 broad, slightly contracted towards the tront, which is regu- 

 larly arched (not incised), and very strongly carinated along the 

 anterior margin ; the anterior two fifths slightly convex, much 

 lower than the remainder of the surface, which is nevertheless 

 deeply excavated in the middle in the form of a broad U, on 

 each side of which are two obtuse cuneiform prominences (not 

 cleft at their extremities as in G. portentosa) ; the lateral 

 margins are slightly carinated : mesonotum bright castaneous, 

 with blackish posterior border and a diamond-shajjed central 

 spot ; very convex, oblong, a little wider at the sides than in 

 the middle, but not produced backwards at the lateral angles, 

 a fairly well-defined central longitudinal impressed line, and 

 a number of scattered coarse shallow punctuations over the
