 tibife is more developed in the female than in the male.*

In the British Museum there are two species of Enaria, 

 which I have briefly described above, evidently closely 

 allied to E. rufofulva, Fairmaire (Ann. Fr., 1880, p. 327), 

 but I cannot reconcile either of them with it. 



E. latifrons is nearly uniform in colour, but the head 

 is a little darker yellow. The front margin of the thorax 

 is slightly sinuate on each side of the middle ; in which 

 it difters from E. marginata, which has it straight. The 

 punctures are rather large and deep, and not very close 

 together. E. latifrons has the posterior angles com- 

 pletely rounded off; in E. marginata there is a slight 



* The important difference in the development of the apex of the 

 posterior tibiae in the Melolontliidcc appears almost to be over- 

 looked by Lacordaire. The females have the apex more enlarged 

 than in the males, accompanied by a greater developnaent of the 

 spines and spurs. This is very observable in the common Melo- 

 luntlia vulgaris, but in some of thelnvger Lep id iota the difference 

 is very great. Under Ancylnnyclia Lacordaire says, "Jambes 

 posterieures evasees an bout surtout cliez les femelles," the only 

 mention of this character vi'hich has come iiiuler my rotice.
