TMETOGONUS. 



2^S 



genus Pseudorychodes Senna, and its facies is very simi- 

 lar to that of some species of the latter , f. i. Ps. Ritsemae 

 (Senna) ') and Ps. insignis (Lewis) ^); the differential characters 

 are: the different shape of the head, which is nearly trian- 

 gular, with the posterior angles broad, prominent and 

 truncate , and the conformation of the anterior tibiae , 

 these being curved and spinous beneath in the apical third. 

 The thighs are as in OrycJiodes Pascoe , but in this latter 

 the spine of the anterior thighs is not at the middle; 

 the sculpture of the elytra and the shape of the head are 

 also different.
