M. tumcchi the first and fifth costse are the longest, and unite below the 

 others, and the posterior patch in the last-named species is triangular, 

 short, not transverse, nearer the apex, and below the fifth costa.

Myrmecopteea FORMOSA, Per., 

 Trans. Entom. Soc. Lond., 1894, p. 451. 



Bronze black, moderately shining on the upper part, dark metallic 

 blue underneath ; head conspicuously strigose ; labrum black, with a 

 median whitish longitudinal band on both sexes ; prothorax nearly 

 quadrate, narrowed in front and behind, with the disk raised on each 

 side and plicate ; elytra gradually ampliated from the base to about 

 two-thirds of the length, convex, ending in two moderately long 

 apical spines, longer and sharper in the male than in the female, 

 each elytron with five costas, the first and second near the suture 

 very wavy, and reaching from the base to two-thirds of the 

 length, the third costa equally long, while the fourth and fifth 

 extend further, reaching to three-fourths of the length ; the intervals 

 between the suture and the first costa and those between the 

 second and fifth costae are broadly plicate, that between the first and 

 second costae divided into six or seven broad, deep foveae, and the 

 space between the fifth costa and the outer margin also broadly 

 foveate in the male, less so in the female ; in the fourth interval 

 runs a basal yellowish-white band reaching about the median part 

 of the disk, and there is a supra-apical, more or less triangular, 

 broad patch of the same colour placed below the fourth and fifth 

 costae ; legs very dark blue. Length 18-20 mm. ; width 5-7 mm. 



Allied to M. mauchi, Bates, but differentiated by the broad and 

 deep foveae in the second interval on the elytra ; the dorsal longitu- 

 dinal white band is longer in proportion, and the apical one more 

 broadly triangular.

Myrmecoptera Maeshalli, Per., 

 Trans. Entom. Soc. Lond., 1894, p. 450. 



Black with a bronze tinge ; elytra brassy, moderately shining ; 

 under side and legs black, with a bluish tinge ; labrum black, 

 with a broad median yellowish-white patch in the male, and 

 a narrow one in the female, head very obliquely plicate between 

 the eyes, and transversely so behind ; prothorax subcylindrical, 

 only a little longer than broad, with the discoidal part somewhat 

 raised on each side, narrowed in front and behind, transversely 

 plicate, and with a median band of white hairs reaching from
