182 ORTHOPTERA. 



Smaller than A. sinuata (Stoll), with the elytra and wings more transparent ; the 

 marginal field of the elytra narrower, and the apex not produced. The elytra are 

 much more sinuated than in A. tessellata, wider and shorter, and not produced at the 

 apex.

ANTEMNA, Stal. 



Antemna, Stal, Syst. Mant. pp. 83, 88 (1877) ; Westwood, Revis. Mantid. p. 22 (1889). 



Vertex haud vel levissime protuberans, interdum in medio tuberculatus. Scutellum faciale circ. dimidio latius 

 quam altum. Vertex tuberculatus. Pronoti ampliatio rhomboidali sat magna ; pars postica anterius 

 haud gibberosa. Pedes validi ; antici compressi, lati. Pemora posteriora lobata, spina geniculari armata. 

 Abdomen $ t'ortiter ampliatum. 



A genus closely allied to Upaphrodita, but with the hind femora more lobed and 

 bearing a geniculate spine. The pupa only of Antemna is known.

 quibusdam nigris; femoribus extus granulis nonnullis nigris conspersis, superne fortiter compressis, 

 ampliatis, parte apicali angustata, margine dorsali obtuse serrulato. Pemora posteriora superne prope 

 apicem lobo angulato, subtus lobis duobus, subapicali maximo, instructa. Tibiae posteriores superne tecti-
