36 PHYTOPHAGA.—SUPPLEMENT. 
metallic blue elytra, and black underside, it is almost impossible to come to a conclusive 
opinion in regard to the number of species which they represent, or which of them 
may be the true L. plumbea, Lac. The examples I refer to L. plumbea have the under 
surface, antenne, and legs (the base of the femora excepted) black; and the elytra 
violaceous-blue, with a feeble basal depression, and deeply punctured strie. Some 
specimens lately obtained by Messrs. Smith and Godman at Orizaba are of a more 
greenish tint above, and are rather smaller and more narrowed posteriorly, and have 
the black colour of the lower portion of the head extending upwards between the 
antenne ; possibly these may represent another species. 
54 (a). Lema yucatana. , 
Rufous, the labrum, antenne (the first joint excepted), the apices of the tibie, and the tarsi black; thorax sub- 
quadrate, moderately constricted ; elytra without basal depression, strongly punctate-striate, the ninth » 
row entire. 
Length 12 line. 
Head impunctate, constricted behind the eyes, the latter prominent and deeply notched ; the labrum and mandi- 
bles black; antenne: half the length of the body, black, the basal joint fulvous ; thorax scarcely longer than 
broad, moderately constricted at the sides, wider in front than behind, the surface with a few very minute 
punctures (only visible under a strong lens); scutellum black ; elytra subcylindrical, without any trace of 
a basal depression, deeply and regularly punctate-striate, the ninth row uninterrupted, the interstices 
strongly costate towards the apex; the posterior femora strongly thickened, reaching nearly to the end 
of the abdomen. 
Hab. Mexico, Temax in N. Yucatan (Gaumer). 
A single specimen. This species belongs to the first division of Lacordaire’s mono- 
graph, it having the ninth row of elytral punctures uninterrupted. JL. yucatana may be 
recognized by its small size, the anteriorly widened thorax, and the colour of the 
antenne. 
55. Lema guatemalensis. 
Lema pudens, huj. op. p. 13 (nec Lacord.). 
To the Guatemalan localities given, add :—Panajachel, Senahu (Champion). 
The specimens referred by me (ante, p.13) to L. pudens proving to belong to another 
species, I now describe it :— 
Black, the extreme base of the femora, the upper portion of the head, and the thorax fulvous ; the latter 
impunctate ; elytra dark metallic blue, with a distinct oblique depression below the base, strongly punc- 
tured anteriorly, finely so posteriorly. 
Length 2-22 lines. 
I am obliged to separate this species from L. plumbea on account of the very distinct 
basal depression and the different system of punctuation of the elytra, the punctures 
being less closely placed and much finer posteriorly. Lacordaire says nothing about a 
basal depression in L. plumbea or L. pudens and only speaks of the longitudinal groove 
within the shoulder, whereas in L. guatemalensis the elytra are distinctly depressed below
