CRYPTOCEPHALUS. 111 
transversely raised space) and a M-shaped thoracic mark; they agree in other respects, 
but the elytra have frequently only seven instead of eight spots. It is quite possible 
that these Panama examples represent a distinct species (perhaps another of Suffrian’s). 
C. 14-pustulatus is placed by its author in a division in which the elytra have a deep 
transverse depression below the shoulders: this depression is visible in most specimens, 
though not to a very marked degree; the punctuation, however, in these examples, 
does not accord with Suffrian’s description. C. guttulatus, Oliv., is a closely allied 
North-American species; but Suffrian’s description of this insect does not agree so well 
with the specimens from our region. C. guttulatus is, moreover, distinguished from 
C. 14-pustulatus by the prosternum being anteriorly produced, a character not shared 
by the Mexican insects. 
This species is figured on Tab. III. fig. 7 under the name of C. tesseratus. 
Cryptocephalus ocellatus (p. 51). 
To the localities given, add :—Mexico, Oaxaca, Cerro de Plumas (Hége), Teapa 
(Hl. H. Smith). 
In most of the specimens which have come under my observation, notably in those 
from Teapa, there are not more than five or six spots visible on each elytron, that is to 
say, that five or six broad spaces are separated by narrow brown lines in the same 
manner as in C. 14-pustulatus. Suffrian gives the number of these spots as eight; but 
specimens so marked are probably rare. C. ocellatus is distinguished amongst its allies 
by the deep and regular punctuation and the raised interstices of the elytra ; the speci- 
mens from Teapa are of a very pale flavous colour. 
Cryptocephalus rhombeus (p. 52). 
_ The Guatemalan localities quoted, and my remarks on the Guatemalan specimens and 
on the one from Zapote figured, refer to C. patheticus. C.rhombeus must be considered 
as a very doubtful species, it having been described from a single female example. 
C. patheticus, on the receipt of a large amount of additional material, proves, like many 
of its allies, to be a very variable insect.
