82 Christmas Island. 



MANTIBARIA, Kirby, gen. nov. 



Head very large, oval, as broad as the thorax, and broader than 

 long; ocelli arranged in an equilateral triangle, antennae inserted 

 close together between the eyes, and set with short hairs, scape 

 slightly curved, about four times as long as broad, second joint 

 rather longer than broad, slightly narrowed at the base and 

 truncated at the extremity ; flagellum nine-jointed, the joints 

 transverse, closely appressed, a little broader than long, except 

 at the extremities, the last as long as the preceding three, and 

 ending in a fine point ; pronotum nearly square, a little rounded 

 in front ; scutellum forming an obtuse-angled triangle, truncated 

 behind, and with a slight central carina ; abdomen moderately 

 broad, with six dorsal segments visible, of about equal length ; 

 legs short, stout, clothed with short hairs, but destitute of spines ; 

 tarsi five -jointed, the first joint rather longer than broad, the 

 second, third, and fourth transverse, the fifth as long as all the 

 rest put together, greatly swollen, and followed by large claws, 

 which are, however, more or less damaged in all the specimens 

 before me, and hence cannot be further described. Rudimentary 

 wings visible under the microscope. 



Affinities uncertain ; I am inclined to refer the species to the 

 Bryinince, but without feeling at all sure that this is its real 

 position.
