Plate XII. fig. 2, L. subtuberculatus magnified ; 2 a, labrum ; 2 b, maxilla of 

 male ; 2 c, mentum. 



A specimen of the male of this species, which, from its close 

 similarity to L. Cancro'idcs, appears to me to be certainly Austra- 

 lian, is also unique in the collection of M. Chevrolat. A rigid 

 comparison with the typical specimen of L. Cancroides might 

 possibly prove that this is but a variety of that insect with which 

 it agrees in size. In M. Chevrolat's collection it bears a pink 

 label.
