LEMA. 13 
Lema bitzniata (p. 4). 
To the locality given, add :—Mzexico, Toxpam, Cordova (Sallé); GuaTemaLa, Panima 
in Vera Paz (Champion). 
The single specimen from Guatemala only differs from the Mexican examples in 
having the antenne fuscous instead of fulvous. 
11 (a). Lema incerta. 
Black, the two basal joints of the antenns, the head, and thorax red; elytra violaceous-blue, the lateral 
margins, a transverse band at the middle, and another at the apex, flavous; femora flavous, the tibie 
black. 
Length 24 lines. 
Hab. Mexico, Tuxtla (Sallé). 
It will only be necessary to point out the differences between L. incerta and 
L. biteniata. The antenne in Z. incerta are shorter, and, with the exception of the 
two basal joints, nearly black (in L. diteniata they are fulvous); and the thorax is 
narrower and more constricted in the middle, and the disc is impressed with a single 
row of rather distinct punctures. The punctuation and the pattern and colour of the 
elytra are absolutely the same as in L. ditewniata, but the tibie and tarsi are black. 
Although there is only a single example before me, there can be no doubt of its being 
a good species. 
11 (s). Lema dimidiaticornis. (Tab. XXXV. fig. 13.) 
Lema dimidiaticornis, de Borre, Ann. Soc. Ent. Belg. xxv. p. 78 (1881)*. 
Hab. Mzxico1, Toxpam (Sallé), Cerro de Plumas (Hége); Panama, Bugaba (Cham- 
pion). 
This species seems subject to a good deal of variation in regard to colour, that is, if 
all the specimens before me are to be regarded as one and the same species. Only a 
single example agrees perfectly with the author’s description; the others differ in the 
antenne being fulvous, with the last joint black or nearly so (in the description the 
antennge are stated to be fulvous with the last four joints fuscous); the fulvous spot at 
the base of the elytra is as often wanting as present, and the central fulvous band is in 
most specimens narrow and of equal width (instead of being broader at the lateral 
margin). L. dimidiaticornis may be separated from L. equestris by the colour of the 
legs and underside, and from L. elegantula and L. biteniata by the elytra not having 
a narrow fulvous or flavous lateral margin. The author states that the punctuation of 
the elytra is rather feeble; in the specimens before me the punctuation is strong and 
deep at the base, but very fine below the middle. In the examples from Bugaba the 
elytra have their central fulvous band narrower and very regular, extending across the 
suture, and the apical spot in the shape of a narrow oblique stripe (instead of a spot as
