LEMA. 25 
across the middle, and the sutural and lateral margins, black; tibie and tarsi and several spots on the 
breast, black. 
Length 32 lines. 
Of robust and convex appearance; the head impunctate, with the usual deep grooves, the vertex with a large 
triangular black spot ; antenne short and robust, gradually widened towards the apical joints, the latter 
not longer than broad, the first two joints fulvous, the rest black; thorax subquadrate, the anterior margin 
straight, the sides moderately constricted, the basal groove almost obsolete but impressed with a small 
fovea at the middle, the surface with some very minute punctures on the middle and anteriorly at the 
sides, the latter with two black spots placed one below the other, the disc with a narrow straight black 
central stripe which extends from the anterior margin nearly to the base; scutellum black; elytra convex, 
broad, with a scarcely visible depression below the base, strongly and closely punctate-striate anteriorly, 
the punctuation gradually diminishing in depth posteriorly, and-with some very small punctures scattered 
between the larger ones, the interstices costate towards the apex; each elytron with a transverse black 
spot on the middle and an obliquely shaped one at the shoulder, the sutural and the lateral margins, from 
a little distance below the base to the apex, also deep black; the epipleure, underside, and femora pale 
fulvous, a spot on each coxa, another at the sides near the anterior coxe, two spots (one anterior and the 
other posterior) on the parapleure of the breast, and the’knees, tibia, and tarsi, black. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Of this well-marked species only one specimen has been received. On account of its 
general robust appearance and the structure of the antenne L. regularis should be 
placed near L. nupta and L. varipes, from which the black margins and the position of 
the spots of the elytra will readily distinguish it. 
36 (c). Lema brunnea. 
Robust, convex, pale brownish, joints 6-10 of the antennw, a central streak and two small spots on the sides 
of the thorax, the apices of the tibie, and the tarsi, black; elytra strongly punctured anteriorly and 
finely so posteriorly. 
Length 34 lines. 
Head impunctate, entirely fulvous, the neck scarcely constricted, the usual grooves deep; antenne short and 
robust, the terminal joints widened and flattened, the five basal joints and also the apical one fulvous, 
the others black ; thorax slightly longer than broad, the sides somewhat deeply constricted, the posterior 
margin strongly rounded, the basal sulcation entirely obsolete, the surface smooth, shining, very minutely 
punctured on the disc, fulvous, with a narrow black longitudinal stripe (interrupted anteriorly and not 
extending to the base), and two small spots placed one below the other at the sides; elytra convex, without 
basal depression, strongly punctured anteriorly and very finely so from the middle to the apex; underside 
and legs fulvous, the extreme apices of the tibiz and the tarsi black. 
Hab. Mexico, Tehuantepec (Sa//é). 
A single specimen, differing from L. nupta and L. varipes in the colour of the 
antenne, absence of elytral spots, and unicolorous underside; it is, however, quite 
possible that L. brunnea is but a variety of L. nupta. 
36 (p). Lema immaculipennis. 
Obscure pale fulvous, the antenne (the basal joint excepted), the knees, the apices of the tibia, the tarsi, and 
some small spots at the sides of the abdomen, black; thorax nearly impunctate ; elytra convex, without 
depression, distinctly punctured at the base only. 
Length 23 lines. 
Head strongly constricted behind the eyes, the latter deeply notched, the lateral grooves also very deep; labrum
