MEMBRA CIDAE. 
examples occur with a pale streak on the pronotum ; tegmina clear hyaline, shining 
like talc, with yellow nervures ; abdomen large, ferruginous, and ringed ; legs long, 
particularly the hind pair, the tibiae of which are pilose; hind tarsi longish; 
suprahumerals short and stout. This species is variable, both in size and colour; 
some are of a greenish hue. 
Size, 8x4 mm. 
Expanse, 19 x 7 mm. 
Habitat. —Guatemala, Panama, Rio Janeiro, Cayenne. 
In the Godman-Salvin Collection there is a long series obtained from different 
localities; their variations probably are dependent on cliinatal and other surroundings. 
Some of these modifications, such as C. minor , may be classed under C. vitulus. See 
B.C.A., p. 103. 
CERESA NIGROVITTATA, Fowler. 
(Plate XXXVI. figs. 1, la.) 
Fowler, l.c. p. 104, Tab. VII. figs. 12, 12a. C. alia (?), Walk. l.c. p. 529. 
Colour shining ochreous yellow, dotted with reddish fine punctures; the pronotum 
is covered with small pentagonal-shaped spots, which seem to be distinctive. Dorsal 
ridge with numerous brown dots; suprahumerals sharp, not much developed, and not 
tipped with black; tegmina hyaline with yellowish neuration ; legs yellow and 
slightly hirsute. This is a large species, which Fowler remarks is very distinct. It 
might prove, however, to be C. bifasciata of Fairmaire, though this latter insect is 
double the size. The triangular form of the metopidium is given in fig. la of this 
plate. 
Size, 8 x 6 to 10 x C mm. 
Habitat. —Chontales, Vera Paz, Nicaragua. 
CERESA ALTA, var. 
(Plate XXXVI. figs. 2, 2a.) 
Walk. l.c. p. 539, ? . 
A comparison of Ceresa nigrovittata with C. alta of Walker leads me to the sup¬ 
position that they may be identical species, although there are differences, particularly 
as relate to the position and size of the black pronotal band. A more complete 
microscopic examination may prove which insect should have the priority. C. alta 
does not occur in the synonyms of the B.C.A., but the habitat of Walker’s insect is 
not given in his list. For comparison I figure these insects, both which are large for 
their particular genus. 
Size, 8 x G mm.
