with dorsal margin oblique and poorly defined laterad, transverse 

 and carinate between the antennal sockets. The dark brown on 

 the internal face of the cephalic femora is more diffuse and blurred 

 than in Westwood's figure. The caudal metatarsus is as long as 

 the combined length of the three succeeding joints. The genitalia 

 are much like those of Opsomantis tumidiceps, except that the supra- 

 anal plate is slightly less produced, the styles of the subgenital plate 

 longer, fully five times as long as the greatest width, separated 

 by a distance equal to four-fifths the length of one of the styles. 



Length of body 24, length of pronotum 4.8, greatest width of 

 pronotum 2.9, length of tegmen 21, width of tegminal marginal 

 field 1.1, length of caudal femur 6.8, length of caudal metatarsus 

 2.1 mm.

Like Compso7nantis semirujula, this species might, at first glance, 

 be mistaken for a member of the genus Amantis, but it is readily 

 distinguished by a number of distinctive characters. 



In the male before us we note that the ocelli are minute and rather 

 widely separated, the facial scutellum distinctly less than half as 

 high as its basal width, with dorsal margin weakly convex- and show- 

 ing slight irregularities. The limbs are all spotted and dotted with 

 dark brown on both internal and external faces, a particularly 

 large dot being situated on the internal face of the cephalic femur 

 at the distal extremity of the unguicular sulcus. The pronotum 

 expands evenly to the portion of greatest width, the lateral margins 

 curving evenly thence to the cephalic extremity, with no trace of 

 concavity anywhere, the margins are entire, without trace of den- 

 ticulation. The caudal metatarsus is scarcely longer than the 

 combined length of the two succeeding joints. The supra-anal 

 plate is evenly rounded, its length slightly less than half its proximal 

 width. The subgenital plate has the lateral portions narrowly 

 turned dorsad, the lateral margins straight convergent; the styles, 

 situated at the narrow extremity and separated by a distance little 

 over the width of one of these, proportionately large, flattened 

 cylindrical, as long as the supra-anal plate, four times as long as 

 the greatest width, with apices rounded.
