At'antliodis variegata Brunner. 



1895, Acanthodis variegata Brunner, Monogr. der Pseudophyll., p. 112. 



One female; Mexico. Coll. Coll. Acad. Nat. Sci. Phila. 



This specimen differs somewhat from Brunner's description in 

 having three species on the lower surface of the anterior femora and 

 four on the lower posterior margin of the median tibiae. 



Gongrociiemis incerta Brunner. 



1895, Gongrocnemis incerta Brunner, Monogr. der Pseudophyll., p. 167. 



Two males; Teocelo, Vera Cruz, Mexico. September. Collected 

 by Otis W. Barrett. 



One specimen does not agree with a female specimen from Jalapa 

 and the other male in the color of the face, which is ashy instead of 

 black. The cerci are long and attenuate, Brunner's description 

 giving these as "breves in apice ipso attenuato." 



luiartliroii clavicercwm n. sp. 



Type: male; Gualan, Guatemala. Mrs. S. P. McElroy (U. S. 

 N. M.). 



Apparently allied to I.furcatum and atrispinum, but differing in 

 the form of the supranal plate which is short aud triangular, and 

 the cerci which are heavy, with the apical portion much expanded 

 and bearing two teeth. 



The singularity of this species causes the author to describe it in 



TRANS. AM. ENT. SOC, XXIX. NOVEMBER, 1902.
