Psyche 
[June 
Colour pale brown thickly covered on bod}^ and tegmina 
with short brown pubescence. Indications of a paler fascia 
about middle of tegmen and at about three-quarters. Hind 
wings infumated. 
Length 4.3 mm. (holotype), 4.2 (allotype), measured to 
tip of closed tegmina. 
The sedeagus is an extraordinary structure — very long and 
tubular, with the distal half more or less membranous, bent back 
on proximal half, to the Xth segment, to the under surface of 
which and to a conspicuous swelling of the membrane beneath, 
it is apparently fastened by hook-like projections. Part of this 
hooking apparatus is a long spirally coiled membranous arm. 
The proximal more chitinised part of the sedeagus is elbowed as 
it leaves the membrane of the pygophor, and more distally bears 
on each side a stout basally directed hook. In the figure (fig. 2) 
for the sake of clearness the lateral appendages of only one side 
are shown. 
Described from 11 specimens, Mina Carlota, Trinidad Mts., 
Cuba, March, 1925 (Nos. 637. 641. 643. 647, 658, 664).

This species differs from the genotype in having a large 
spine on the middle of the hind tibia, as do all the Cuban repre- 
sentatives (Metcalf and Bruner). 
Judging from the descriptions, it differs from L. grisea M. 
& B. in its smaller size, the middle spine of hind tibia being much 
more than twice as long as basal one, the pronotum much longer 
than crown and differently shaped; from L. balloui M. & B. in 
its longer vertex and in colour; from L. nagua M. & B. in being 
larger and more slender in all proportions; from L. mcestralis M. 
& B. in having head much narrower than pronotum; from L. 
pilece M. & B. in colouration and in the long vertex; and finally 
from L. fulva M. & B. in its smaller size, in the absence of straight 
sides to the vertex, and of carina to the pronotum. 
L. collina was swept from mixed bushy undergrowth, and 
on two occasions from lantana ( Lantana camara L.),
