Vol. Xxiii] ENTOMOLOGICAL NEWS. 263 



Mesonotum with dorsal margin projecting caudad of pronotum nearly 

 half the dorsal length of the latter. 



Metanotum surpassing the mesonotum by slightly more than half the 

 length of latter. 



Proximal abdominal segment compressed cristato-carinate as in the 

 thoracic segments, exposed portion equal to that of the mesonotum ; 

 remaining abdominal segments not elevated and hardly even carinate 

 dorsad. 



Cephalic and median limbs rather short. Caudal femora compressed, 

 robust, dorsal carina with eight spiniform serrations becoming elongate 

 spines distad, spine on dorsum of genicular region decided, caudal ex- 

 tremity of genicular arches and genicular lobes spiniform, remaining 

 femoral carinae simple; caudal tibiae armed with fifteen spines on 

 each margin. 



General color (specimen mounted from alcohol) clay color, eyes 

 ochraceous, limbs washed with broccoli brown; genicular arches, tips 

 of spines on dorsal carina of caudal femora, genicular region of caudal 

 tibiae and an area on the keel of the mesonotum blackish; tibial spines 

 black with yellow bases. 



MEASUREMENTS. 



Length of body 18.5 mm. 



Length of pronotum 6.5 mm. 



Greatest (caudal) depth of pronotum 9.5 mm. 



Length of caudal femur 1 1.8 mm. 



Four paratypic females have been examined in addition to 

 the type. One specimen is slightly below the average size of 

 the remainder of the series, but otherwise no points of differ- 

 ence are noted. 



We take pleasure in dedicating this species to Dr. Malcolm 

 Burr, the eminent English Orthopterist, in token of apprecia- 

 tion of his valued work on the Eumastacinae.

 Allied to T. zebra Gerstaecker, described from the Cameroons, 

 but differing in the more produced ventro-caudal angle of the 

 lateral lobes of the pronotum, the much more recurved and in- 

 flated apex of the male abdomen, the more elongate subgenital 

 plate of the same sex and the slightly greater size.
