206 HETEROMERA.

A common species in our country, whence we have received a large number of exam- 
ples. LZ. kirschi and L. inscriptum (the types of which are before me) are perfectly 
identical; Z. fulvwm is probably an immature example of the same species. 
According to Chevrolat (op. cit. p. 243, nota), from whose collection the insect was 
originally described, Platydema 4-notata, Lap. & Brullé (P. spheridioides, Dej. Cat.), 
from Colombia, is a Liodema: the description of this species nearly agrees with our 
insect, excepting as regards the rather smaller size, and the coloration of the antenne ; 
in one or two Mexican examples, however, I find that the intermediate joints of the 
antenne are slightly infuscate, instead of being wholly testaceous, as is almost invariably 
the case. With the large amount of material before me, I think it extremely pro- 
bable that our insect is identical with L. guadrinotatum. . 
Immature examples of this variable insect are slightly shining, and often have the 
elytral markings less sharply defined ; in some specimens the first red spot is crescent- 
shaped (the angles towards the base) and extends obliquely to the scutellum, in others 
it is oblique and sometimes ill-defined; the second spot is invariably more or less 
crescent-shaped (the angles towards the apex) and extends along the margin of the 
elytra to the sutural angle. The elytral strie are usually almost obsolete, or very finely 
and indistinctly impressed; in one or two individuals, however, the punctures are 
coarser and more distinct. 
This and the following species superficially resemble the genus Spheridium, of the 
Hydrophilide. A fairly typical example from Capetillo is figured.

Central-American examples agree, as already noted by Chevrolat, with L. obydense 
from the Amazons. . 
LL. tenuicorne, Chevr., from Caracas *, is very possibly a dark variety of this species. 
4. Liodema zimmermani. (Tab. IX. fig. 14.) 
Ovate, moderately convex, reddish brown, slightly shining. Head with the basal half brownish black, the 
frontal half red, finely and closely punctured; eyes strongly oblique, not widely separated; antenne 
serrate from the fourth joint; prothorax transverse, the sides rounded in a line with the elytra and
