2. Stictocephala dubia, sp. n. ° 
Testacea vel virescenti-testacea, capite dilutiori; pronoto densius et distinctius punctato, humeris distincte 
prominulis, processu apicali, carina dorsali usque ad medium et carinis anticis lateralibus late rufis, 
punctis quibusdam albidis, colore nisi in recentibus exemplis multo dilutiori et decolorato, seepe uniformi, 
testaceo ; corpore subtus toto testaceo, abdominis disco raro infuscato; pedibus testaceis. 
Of a testaceous or greenish-testaceous colour, with the head lighter and the pronotum broadly red along the 
dorsal and lateral keels, proceeding in front from the dorsal keel, the red and part of the testaceous colour 
in quite fresh specimens being sprinkled with minute whitish spots; the colour, however, is extremely 
variable, and the red seems very fugitive; the punctuation of the pronotum varies considerably, but is 
usually distinct, and is coarser at the sides; the underside is testaceous, the disc of the abdomen being 
rarely dark ; legs testaceous. 
Long. cum tegm. 6-63 millim. ; lat. int. hum. 24-3 millim. 
Hab. Mexico, Chilpancingo in Guerrero, Cuernavaca in Morelos, Teapa in Tabasco 
(H. H. Smith), Atoyac in Vera Cruz (Schumann), Orizaba (H. H. S. & F. D. G.), 
Temax in North Yucatan (Gaumer); GuaTEMALA, near the city (Champion). 
This species is very variable in colour and in a certain degree in shape, and I have 
had to go to a great extent by the localities in keeping the specimens united. It 
is quite probable that Ceresa chlorotica and C. uniformis, Fairm., are forms of this 
species, but it is impossible to identify them from the descriptions, which are practically 
the same in both cases, or from the old uniformly testaceous and evidently faded 
examples which stand in the Belgian and Vienna Museum collections under these 
names. In the British Museum collection there is the single type of Thelia rufivitta, 
Walker (from Florida), which is a Stectocephala and comes very near the most brightly 
red-coloured examples of this species, and may perhaps belong to it; the formation, 
however, of the shoulders is different. 
Var, major. 
Virescens, major, distinctius fortiusque punctata. 
Much larger than the type, of a greenish or greenish-testaceous colour, with the punctuation stronger. 
Long. cum tegm. 8 millim. ; lat. 4 millim. 
Hab. Mexico (Sailé), Ciudad in Durango 8100 feet (Forrer), Chilpancingo in 
Guerrero 4600 feet (H. H. Smith). 
This variety looks exceedingly different from the type-form of the species, but it is 
not distinct enough to be separated unless more examples can be discovered, as there 
is at least one typical and one or two intermediate forms from the same locality. 
3. Stictocephala fusca, sp.n. (Tab. VII. figg. 17, 17 a.) 
Fusco-brunnea, capite metopidioque supra caput flavo-testaceis ; pronoto dense et distincte antice subrugosius 
punctato, humeris prominulis sed variantibus ; abdomine testaceo ; pedibus dilute testaceis. 
Very like some of the forms of the preceding species, somewhat variable in shape, of a fuscous-brown cclour, 
sometimes with very small lighter spots on the disc and at the sides of the pronotum, which are more 
strongly punctured than the front part, where the punctuation is thick and finer and slightly subrugose ;
