LEMA. | 15 
Head impunctate, black, with the usual grooves; antenne black, the three (sometimes four) apical joints 
flavous, the fourth joint twice as long as the third; thorax about as long as broad, somewhat deeply 
constricted at the middle, the transverse basal sulcation not strongly marked, the disc with two rows of 
minute punctures arranged longitudinally, and the space between sometimes with a longitudinal groove ; 
elytra with a distinct transverse depression below the base, deeply and regularly punctate-striate anteriorly, 
the punctuation becoming very much finer below the middle, and here replaced by lines, the interspaces 
between which are raised, each with a broad transverse flavous spot or band at the middle (not extending 
to the suture or lateral margin), and a rounded spot near the apex, the latter surrounded posteriorly by a 
narrow margin of the ground-colour; breast and legs black; abdomen flavous. 
Hab. Panama, Bugaba, David (Champion). 
Numerous examples. In a single specimen the anterior femora are flavous, and the 
posterior femora have a flavous spot at the middle. 
12 (vp). Lema sexplagiata, (Tab. XXXV. fig. 15.) 
Head, the eight lower joints of the antenne, and the breast, black, the thorax, the femora more or less, and the 
abdomen, flavous; elytra black, a spot at the base, a larger one at the middle, and the apices, flavous. 
Var. Legs entirely black. 
Length 23-3 lines. . 
Head deeply constricted behind, almost impunctate, the space surrounding the eyes alone finely punctured ; 
antenne black, the three (sometimes four) apical joints flavous, long and slender, the third joint twice as 
long as the second, but shorter than the fourth; thorax scarcely longer than broad, deeply constricted at 
the sides, the basilar sulcation almost obsolete, the disc impunctate, flavous, the basal margin (in some 
specimens) black; elytra without trace of a basal depression, finely punctate-striate, the punctuation 
scarcely stronger anteriorly than posteriorly, the interstices towards the apex more or less distinctly 
costate, black, with a round spot immediately below the base, a larger and more transversely shaped one 
_at the middle, and the apices broadly, flavous; legs variable in colour, generally flavous, the base of the 
femora and their upper portion as well as the tibie and tarsi, black; abdomen flavous. 
Hab. Panama, Bugaba (Champion). 
Many specimens. In general coloration and in the pattern of the elytra L. sexplagiata 
exactly resembles L. apicicornis, a species obtained at the same locality; but differs in 
its generally smaller size, and in the elytra being without a basal depression, and having 
an extra spot placed near the base. The elytra in L. sexplagiata are flavous at the 
apex as well as at their margins (in L. apicicornis a narrow black margin surrounds 
the flavous portion), and their ground-colour is, moreover, entirely black instead of being 
of a distinct blue shade at all the darker portions as in L. apicicornis. In some speci- 
mens the black bands separating the elytral spots do not extend to the lateral margins, 
these latter as well as the epipleure remaining flavous; in all the lower margin of the 
posterior black band is deeply emarginate. 
Lema transverso-fasciata (p. 4). 
To the localities given, add:—Panama, Bugaba (Champion). 
Panama specimens differ from those from Costa Rica in having a slightly narrower 
blue band to the elytra, and in the interstices between the punctures being somewhat
