I do not know any species nearly allied to this. It is 
easily distinguished by its bright yellow ovisac, bristly margin 
of the female, long femoral bristle, and the large thick digi- 
tules of the claw. It is possible that the two bristles ascribed 
to the trochanter are really on the distal end of the coxa. 
(8) Lecantum olee (Bern.). 
City of Mexico. 
(9) Lecanium hesperidum (L.). 
On stems of rose, Vera Cruz; on tree (not identified), City 
of Mexico. 
(10) Lecantum terminalie, Ckll., var. 
On leaves of a liliaceous plant, Vera Cruz. 
@ (adult). Margin with very few (simple) hairs. Derm 
with small circular gland-spots. Sides of scale with radiating 
pigment-bands. Parts of the scale and insect turn reddish 
purple in soda. Anal plates with their posterior external 
margins considerably longer than their anterior margins. 
Legs small; tarsus with slender knobbed hairs, knobs rudi- 
mentary ; tarsus about two thirds length of tibia; tibia about 
three fourths length of femur. 
Eggs oval, granular. 
Larva with long and slender knobbed tarsal hairs, the knobs 
rudimentary. Femur decidedly shorter than tibia+ tarsus. 
L. terminalia was described from specimens found on 
Terminalia at Jamaica, and its occurrence on a liliaceous 
plant at Vera Cruz was quite unexpected, so much so that 
until | examined the details of its structure I did not suppose 
I had terminalia, but rather Signoret’s acwminatum, which 
was found on orchids in a Parisian hothouse. 
These Vera-Cruz terminalie were only a few feet away 
from arose-bush swarming with hespertdum, and as one looked 
at them it was hard not to conclude that they were all one 
species, the terminalie modified by the nature of the food- 
plant. Yet in Kingston, Jamaica, where one finds terminalie 
on Terminalia, I have found occasionally on liliaceous plants 
true hespertdum, and not terminalie at all! 
In some few respects, such as the details of the feet, the 
Vera Cruz specimens differ from typical terminalia ; but I am 
certainly not prepared to make a new species out of them on 
these grounds. From acuminatum they differ in the length
