34 PHYTOPHAGA.—SUPPLEMENT. 
L. flavipennis seems to belong to Lacordaire’s thirty-first group, and is no doubt 
closely allied to L. simples, L. ferrugata, and L. helvola. It seems to differ, however, 
from all of these in the want of the basal depression of the elytra, the scarcely con- 
stricted sides of the thorax, and the entirely black antenne. In one specimen the 
space surrounding the inner margin of the eyes is black. ‘The space at the sides of the 
elytra occupied by a remnant of the ninth row of punctures is broad, smooth, and 
costiform. 
49 (p). Lema planipennis. 
Fulvous, the five basal joints of the antenne, the labrum, the apices of the tibia, and the tarsi black; thorax 
with some fine punctures on the disc; elytra metallic green, flat, without basal depression, strongly and 
regularly punctured, the interstices costate at the apex, the ninth row of punctures interrupted. 
Length 2 lines. 
Head with a short fovea between the eyes, the latter not very deeply notched, the space in front clothed with 
yellow pubescence; labrum black; antenne about half the length of the body, the six apical joints 
fulvous, the others black ; thorax very slightly longer than broad, scarcely constricted at the sides, the basal 
sulcation not very deep, the disc with two rows of fine punctures at the middle and some other punctures 
near the sides anteriorly; scutellum fulvous; elytra somewhat flattened, without basal depression, very 
regularly and deeply punctured throughout, the interstices at the apex and at the sides costate. 
Hab. Muxico, Ventanas in Durango (forrer). 
L have no doubt about the specific distinction of this insect, although I have only a 
single specimen for examination. ‘The colour of the antenne, the scarcely constricted 
thorax, the unimpressed base of the elytra, and their deeply impressed and regular strie 
of punctures visible to the apex, form characters by which L. planipennis may be 
recognized with comparative ease. 
49 (n). Lema approximata. 
Flavous, the head, antenne, tibie, and tarsi black ; thorax subcylindrical; elytra testaceous, the apex greenish, 
subgeminate punctate-striate, a broad sutural and a broad lateral stripe, black, the ninth row of punctures 
interrupted. 
Length 2 lines. 
Head black, the neck fulvous; the vertex with a narrow central groove; eyes deeply notched, the lateral 
grooves deep; antenne half the length of the body, entirely black; thorax subcylindrical, fulvous, 
slightly longer than broad, the sides moderately constricted, the basal sulcation distinct but not deeply 
impressed, the surface impunctate; scutellum black; elytra narrowed posteriorly, with a very obsolete 
depression below the base, the punctuation anteriorly arranged in double rows, the interstices towards 
the apex very broad and costate, the punctures nearly obsolete behind, the ninth row only distinct 
anteriorly, with a broad sutural and a broad lateral longitudinal black stripe, the latter at the shoulder 
widening into a subquadrate spot; underside entirely flavous, covered with fine silvery pubescence; tibiae 
and tarsi black. the posterior tibiee slightly curved. 
Had. Guatemata, Torola (Champion); Panama, Taboga Island (Champion). 
This species seems closely allied to the Colombian L. marginata, Oliv. ; the head and 
antenne, however, are entirely black; and the elytra have their punctures somewhat 
arranged in double rows, and are more or less greenish towards the apex. In the 
female the antenne are shorter than in the male.
