110 HEMIPTERA-HOMOPTERA. 
the shoulders are slightly prominent, but more so in some specimens than in others; the head and front 
part of the metopidium are yellow-testaceous, and occasionally the hinder part of the pronotum is reddish ; 
the abdomen is testaceous, and the legs clear testaceous, the colour in some specimens being very light. 
Long. cum tegm. 6 millim.; lat. int. hum. 3 millim. 
Hab. Mexico, Presidio de Mazatlan (Forrer). 
Several specimens. It is quite possible that this may be only a variety of the 
preceding species, but the examples are quite fresh and differ considerably in colour 
and general appearance from the type specimens of S. dubia. 
4, Stictocephala elongata, sp.n. (Tab. VII. figg. 18, 18 a.) 
Elongata, angusta, viridescens; pronoto a latere viso minus elevato, supra viso depresso, antice subtilius ad 
latera parcius fortiusque punctato, carina dorsali laté obtusa utrinque apicem versus compresso-sulcata, 
humeris rotundatis, haud prominulis ; abdomine pedibusque totis testaceis. 
Narrow and elongate, with the pronotum greenish, the head and front part of the metopidium being testa- 
ceous; pronotum very narrow between the shoulders, which are rounded and not prominent, finely 
punctured in front, coarsely at the sides, with the flattened front part before the dorsal carina very long, 
the dorsal carina being obtuse and broad and compressed and indistinctly sulcate on each side of the 
apical process ; the abdomen and legs are entirely testaceous. 
Long. cum tegm. 7 millim.; lat. int. hum. 23 millim. 
Hab. Mexico, Ciudad in Durango 8100 feet (forrer). 
One female specimen. This is one of the most distinct of all the representatives of 
this genus in our collection. 
5. Stictocephala cornuta, sp. n. 
Testacea, nitida, capite metopidioque supra caput flavis; pronoto dense fortiusque, ad latera parcius, punctato, 
humeris in cornua modica sat acuta vix reflexa productis, cariné dorsali et carinis lateralibus ex hac 
procedentibus cum cornibus lete rufis, his ad extremum apicem nigris, impressione laterali semicirculari 
conspicua, processu apicali acuto toto rufo ; corpore subtus pedibusque flavo-testaceis. | 
Of a testaceous colour, with the head and front of the metopidium lighter, and with the dorsal keel and keels 
proceeding from this broadly and brightly red, the surface being often flecked with small light spots and 
in front with greenish spots or patches; the pronotum is distinctly punctured, more coarsely at the sides, 
where the lateral semicircular impression is very distinct, and is produced in front into two moderate 
horns, which are stout and very slightly reflexed, and are red, with the extreme tips black; the apical 
process is long and acute, red; the underside and legs are entirely of a light testaceous colour. 
Long. cum tegm. 7 millim. ; lat. int. hum. 44 millim. 
Hab. Panama, Bugaba (Champion). 
Two males and one female. This species is like a Ceresa in general appearance, but 
the formation of the apical appendages of the male (which are exposed and visible in 
the type specimen) shows clearly that it must be referred to Stictocephala. 
There are three rather coarsely punctured specimens of a Stictocephala in our 
collection (one male and two females), labelled “ Quezaltenango, Guatemala, 7800 feet 
(Champion),” which have the underside infuscate in both male and female, and may 
perhaps belong to another species, but they are too much faded and discoloured to 
identify or describe.
