20 PHYTOPHAGA.—SUPPLEMENT. 
L. hamata. The Panama specimens have the elytral markings blue instead of black, 
as stated by Lacordaire. 
Lema biannularis (p. 7). 
To the locality given, add :—Muxico, Cordova (Sallé), Jalapa, Tapachula in Chiapas 
(Hoge); Costa Rica (Van Patten), Cache (Rogers); Panama, Volcan de Chiriqui 
(Champion). 
The type of this species is unfortunately not contained in the British Museum, and 
is probably lost. The numerous specimens received from the above localities nearly 
agree with Clark’s description, but show so much variation amongst themselves that it 
is quite impossible to say if all (or any) of them represent the true L. biannularis; in 
several the elytral rings are blue (not black, as stated in the description); and the 
posterior semilunate mark is scarcely of the same shape in any two specimens, it being 
more or less curved or straighter, and longer or shorter, in different individuals. The 
Chiriqui examples are much smaller, and have the elytral markings equally variable in 
shape. Clark gives Guatemala as the locality, whence, in spite of the very large 
amount of material at my disposal, I have not seen a specimen. If I were to treat 
those before me as distinct, I should have to describe half a dozen extremely closely 
allied and doubtful species. For the present I prefer to regard them as belonging to 
one variable and widely distributed species. 
Lema bicincta (p. 7). 
To the locality Mexico, add :—Jalapa, Colima city (Hége), Cuernavaca, Juquila (Sallé). 
To judge from Lacordaire’s description it is somewhat doubtful whether the specimens 
obtained from the above localities really represent this species or L. lucublanda, Lac. ; 
I think that I rightly refer them to ZL. bicincta. In all our examples (with one 
exception) the first joint of the antenne is black (of which Lacordaire says nothing); 
the anterior blue band of the elytra is rather deeply dentate at its posterior margin, 
and the posterior band is only half the width of the anterior one, and does not extend 
(as it is stated to do in L. bicincta) to the lateral margin. I am, however, unable to 
find any other difference, and it is quite possible that the bands of the elytra are subject 
to variation. 
80 (a). Lema chiriquensis. (Tab. XXXV. fig. 18.) 
Testaceous, the basal joint of the antenne, the head, and the breast black ; elytra strongly punctate-striate 
anteriorly, a broad transverse band at the base and another below the middle violaceous-blue 
Length 23-3 lines. - 
Hab. Panama, Volcan de Chiriqui (Champion), Colon (Boucard). 
LL. chiriquensis averages rather smaller in size than Z. bicincta, and differs in having
