1891.] MICRO-LEPIDOPTERA OF THE WEST INDIES. 497 



Cacoecia, Hb. 

 Caccecia jamaicana, Wkr. 



Teras jamaicana, Wkr. Cat. Lp. Ins. B. M. xxviii. p. 291 (1863). 

 West Indies — Jamaica {Wkr.). 



This species was wrongly included in Teras by Walker ; it should 

 be transferred to Caccecia, with which it agrees in structure. 



TORTRIX, L.

Tortrix effoetana, Mschl. Ab. Senck. Nat. Ges. xv. pp. 330, 3.04

These two species being described from females, it is impossible 

 to say whether they are rightly referred to the genus Tortrix. 



Ptychamorbia, gen. n. 



(7rrii^ = a fold ; Amorbia, nom. gen.)

Palpi conical, densely clothed, apical joint moderate ; projecting
