In the male two segments, in the female one, before 

 the apical are white and luminous; the structurai characters 

 of the apex are as usual in this genus.

Photuris axillaris, Mots. Etud. Ent. iii. p. 61. 



If I am right in my reference, this is very like late- 

 fascia in form and details, but the elytra are nearly 

 black, only the middle of the suture and margin being 

 yellow.

Of similar form with the three preceding species, which 

 all have the thorax very small compared with the length 

 and amplitude of the elytra ; the eyes of the males are 

 rather large and prominent ; the luminous segments are 

 particularly conspicuous, and not clouded in either sex.
