104 HEMIPTERA-HOMOPTERA. 
3. Ceresa nigricornis, sp.n. (Tab. VII. figg. 11, 11 @) 
Griseo- vel virescenti-testacea, cornibus et carina dorsali et apice extremo pronoti nigris, et macula fusca 
utrinque ante apicalem processum; capite testaceo; pronoto nitido, haud dense punctato, cornibus 
acutis, sat longis, vix reflexis; tegminibus pedibusque dilute testaceis. 
Allied to C. vitulus, but with the horns rather longer and straighter, and of a black colour, which is continued 
below to the margins of the pronotum, and above almost to the highest part of the dorsum, the dorsal 
carina and the extreme apex of the pronotum being black ; just at the base of the apical process there is 
an indistinct fuscous spot, with a light patch just above it, and there are also some scattered whitish points 
on the disc, which are more evident in some specimens than in others; tegmina and legs testaceous. 
Long. cum tegm. 8—9 millim. ; lat. int. corn. 5 millim. 
Hab. Mexico, Teapa in Tabasco (H. H. Smith). 
Two males and two females. 
4, Ceresa nigrovittata, sp.n. (Tab. VII. fige. 12, 12a.) 
C. vitulo affinis, sed major, et vitté lata nigra ante apicalem processum pronoti facile distinguenda, hac vitta 
supra subtusque macula testaced, et supra quibusdam aliis punctis testaceis instructé; cornibus anticis 
acutis modice reflexis; tegminibus cum venis pallide testaceis; venis alarum fuscis; pedibus testaceis. 
Allied to C. vitulus, but considerably larger than the average specimens of that species, and easily distinguished 
by having a broad black band just before the apical process of the pronotum, bounded above and below 
by a testaceous mark, and with a few small testaceous spots above, which are sometimes sprinkled over 
the whole dorsal portion ; the tegmina and legs are testaceous; the general colour of the pronotum is 
more or less rufo-testaceous, but occasionally it is lighter, and sometimes there is a slight brown tinge. 
Long. cum tegm. 9-10 millim. ; lat. int. corn. 5 millim. 
Hab. GuaTeMALa, Sabo in Vera Paz (Champion). 
Several specimens. This is a very distinct species. I have not seen C. difasciata, 
Fairm., which is described as having a black marking at the apex, but that species 
appears to be about half the size of C. nigrovittata and to differ in other points. 
5. Ceresa uncicornis, sp.n. (Tab. VII. figg. 13, 18a.) 
Lete rufescens, pronoto nitido, parce punctato, maculis quibusdam vel vittis testaceis, vitté ante apicalem 
processum et apicali processu plerumque plus minusve distincte testaceo, apice extremo nigro; pronoti 
cornibus aculeatis, fortiter recurvis, nigris vel nigro-apicatis vel rufis ; tegminibus testaceis, pedibus rufo- 
testaceis. 
Of a bright rufescent colour, with testaceous streaks and markings, which in some specimens are very apparent 
and in others indistinct; there is a light patch just before the apical process, which is for the most part 
testaceous, with the extreme tip black ; the light marking round the depressed part at the sides of the 
pronotum, which is characteristic of the group, is also more or less distinct ; the chief character, however, 
lies in the horns, which are very aculeate and very strongly recurved; the tegmina are testaceous and 
very shining, and the legs rufo-testaceous. 
Long. cum tegm. 104 millim. ; lat. int. corn. 5 millim. 
Hab. Panama, Volcan de Chiriqui 2500 to 6000 feet (Champion). 
This species is allied to C. axillaris, Fairm.; at first sight it looks very distinct, but 
it leads through an almost entirely rufescent variety into the next species, with which, 
except for the form of the horns, it is very closely connected.
