Of the anteniite, joints 1 and 2 are stouter than any of the fol- 

 lowing 6, and are together scarcely so long as joints 3-5 together ; 

 3 and 4 are equal inter se, each much shorter than 2 ; 5 is very 

 evidently but not very much longer and stouter than 4 ; 5-8 are 

 equal inter se, and eacli a little smaller than 4 ; 9 is short and 

 transverse, about as wide as 1 ; 10 not much longer than, but 

 nearly twice as wide as, 9 ; 11a little wider than, and about 

 twice as long as, 10 ; none of the joints 1-8 are transverse, 



Femina. A mare differt antennis (pra?sertim articulis inter- 

 mediis) obscurioribus, longioribus, articulis aliter propor- 

 tionatis ; metasterno postice minus fortiter impresso, ab- 

 domine simplici. 



Of the antennae of the female, joints 3 and 4 and 6-8 are a 

 little more elongate ; 5 is not much longer or stouter than 3 ; 9 

 and 10 are together about as long as 6-8, neither of them trans- 

 verse, 10 longer and wider than 9 ; 11 is a little longer but 

 .scarcely wider than 10. 



The superficial characters of this species seem to be near those 

 of Bryaxis vitrea, Scliauf., of which no sexual distinctions are 

 recorded by its author ; the difference in colour is considerable, 

 so that tliis form is at least deserving of a varietal name, even 

 if it should eventually turn out to be a form of vitrea.

Of the antennae, joints 1-3 decrease successively in tliickness, 



2 and 3 being almost equal to each other in length, 1 a little 



longer ; joints 3-8 scarcely differ in thickness, except 5, whicli is 



scarcely thicker than the rest ; 4, 6, and 7 are equal inter se, each 



a little shorter than 3 and 5, which are of equal length ; 8 is a 



little shorter than 7 ; 9 is almost globular, a little longer and 



stouter than 8 ; 10 is a little longer than 9, and nearly twice as 



wide, being pretty strongly transverse ; 1 1 is very little wider
