LEMA. 11 
example the head is entirely rufous (without the narrow black space surrounding the 
eyes), the thorax is slightly more transverse, and the femora are tinged with fuscous at 
the apex; other differences I am not able to find, and although it is possible that this 
specimen may represent a closely allied but distinct species (on account of the more 
transversely shaped thorax) I am not able to say so with certainty. The very fine 
punctuation from the middle to the apex of the elytra will assist in the better recog- 
nition of L. amabilis. 
5 (c). Lema interstitialis. 
Ferruginous, the antenns (the first joint excepted), knees, tibie, and tarsi black; thorax punctured on the 
disc; elytra dark metallic blue, finely punctured, the interstices minutely punctate. 
Var. The four anterior legs and the base and apex of the posterior femora black. 
Length 23-33 lines. 
Head impunctate, without central groove; the eyes deeply notched; antenne half the length of the body, 
black, the first joint fulvous; thorax slightly longer than broad, the sides moderately constricted, the 
surface with two rows of small punctures, not extending to the base, the basal sulcation shallow; scutellum 
fulvous; elytra almost imperceptibly depressed below the base, the latter more deeply punctured than the 
rest of the surface, the interstices somewhat transversely wrinkled and impressed with more or less distinct 
fine punctures, the lateral margins strongly thickened and accompanied by a row of deep punctures ; 
underside and the femora ferruginous, the knees, tibia, and tarsi black. 
Hab. Muxico, Toxpam (Sailé). 
L. interstitialis differs from L. amabdilis in having only the basal joint (instead of the 
first two joints) of the antenne fulvous, in the punctured thorax, and in the elytra 
being scarcely depressed below the base; and also in the finely punctured interstices 
of the elytra. The allied Z. chalybeipennis, Lac., has the lower part of the head and 
the antenne entirely black, and the basal depression of the elytra deep. Two speci- 
mens, also obtained at Toxpam, are considerably smaller and differ from the type, as 
well as from each other, in having the femora almost entirely, or partly at the apex, 
and the sides of the breast, black; it is possible that they represent a closely allied but 
distinct species. L. mannerheimi, Lac., from Cuba and San Domingo, differs from 
L. interstitialis in the colour of the head, antenne, and legs.

I give a fresh description of this species, to which I refer two specimens contained in 
the Sallé collection :— 
Black; thorax subquadrate, punctured on the disc; elytra metallic blue, with a narrow transverse fulvous
