I cannot bring myself to differ from Trimen, and to accept the 

 concluKion of Watson, that L. levubtt, Wallgr., should constitute tlio 

 type and sole representative of a genus. The difference between 

 this species and the others given belo^^' are certainly rather of 

 specific than of generic grade. I therefore sink Wallengren's 

 genus LmcocMtonca as a synonym of Ahantis, Hopff., as has 

 already been done by Trimen,

With the figures of their species, given by Westwood and 

 Butler, before me and a long series of specimens labelled by 

 Mr. Trimen to compare with them, I am wholly at a loss to see 

 what valid reason exists for separating the insect recognized by 

 Dr. Butler as Sapaa trimeni from the insect described by West- 

 wood. It is true that the normal colour of the sides of the 

 abdominal segments of the insect is " snow-white," as stated by 

 Dr. Butler, and brought out in his excellent figure, but the fact 

 that Westwood says that these segments in the type were 

 ' luteous " does not in my judgment furnish sufficient reason to
