CERESA NITIDALIS, n.s. 
(Plate XXXVI. tigs. 3, 3a, 3b.) 
Very shining, globose; colour uniformly sordid ochreous, with the fore part 
browner; tegmina short; membrane clear hyaline, with five more or less rounded 
apical cells, and oblong sinuous discoidal areas ; pronotum free at the apex, lurnished 
with two short obtuse and inconspicuous suprahumerals, most easily seen lrom the 
front; dorsal outline rounded, and ending in a sharp posterior process ; the scutellum 
covered ; hind tarsi the longest; f'rons bounding the metopidium by a sinuous suture; 
pilose ; marginal edge of pronotum irregular ; the neuration of the tegmina is brown, 
and seems to be abnormal. 
Size, 9x5 mm. 
Habitat unknown.

CERESA TESTACEA. 
(Plate XXXVI. figs. 4, 4a.) 
Fairm. l.c. p. 284. Ceresa patruelis, StSl. Stett. ent. Zeit. p. G9. C. Stdlii, Butl. l.c. Cist 
Ent. ii.: p. 217, t. 3, fig. 11. 
Large; colour bright ochreuus and punctured; the dorsal ridge more or less 
arcuate in some examples, but less circular in others ; the horns short, and inclined 
to rufous colour. Fairmaire states that the dorsal edge is black. This character 
is variable. Tegmina transparent grey, with fine venation ; eyes large. Widely 
spread over Central America. Volcan de Chiriqui. 
Size, 12 x 7 mm. 
Fowler gives as probable synonyms of Ceresa testacea, C. cavicornis (Stal), 
C. fasticliosa (Fairm.), C. alta (Walk.). 
He also thinks that C. alta may be allied to the North American species C. taurina 
and C. constans. 
He examined Signoret’s types which were used by Fairmaire for his description 
of C. testacea , and he found them to vary considerably. 
Gunus: STICTOCEPHALA (Stal). 
The chief reliable difference between this genus and Ceresa appears to consist in 
the form of the last abdominal segment of the male, which in Stictocephala shows 
the styles much shorter than the same parts of Ceresa. Our present knowledge of 
the group, however, is very unsatisfactory, and the examples available are as a rule 
too faded to give clear diagnosis of species. All the known examples are from 
localities in North America. Typical drawings of the genetalia are much wanted. 
Unfortunately my materials are too scanty to supply these details.
