Insecta maxima, valida, prasina. Femora antica extus spinis 7. Tibiae antieae spinis numerosis (eirc. 15 : 20) 

 armatae. Lamina supra-analis anguste elongata. Yertex sat compressus. Margines pronoti integri, 

 excepto in ejus ampliatione. — $ $ . Elytra cordiformia, coriacea, acuminata ; campo marginali plus quam 

 dimidiam latitudinem elytri efficiente ; vena principali in apice elytri desinente. Alarum vena ulnaris 

 biramosa. — <$ 8 • Elytra et alae longissima, vitrea. Cerci longissimi, articulis basalibus 8-10 brevissimis. 



This genus comprises the largest representatives of the family Mantidse. The males 

 and females are very different in the structure of their wings ; but they are easy to 

 unite by the form of the pronotum and cerci. The species are very rare in collections ; 

 we know of only one. 



The genera Macromantis, Metriomantis, and Hicetia form together a very natural 

 group, bearing much resemblance to Cardioptera ; but that genus forms a parallel 

 group belonging to the tribe Vatinse.
