NEANUS, gen. nov. 
Oblongo-ovatus ; capite sat magno; metopidio magno, convexo, levi, vertice supra metopidium marginato, 
carinato ; oculis a latere visis fere rotundatis, prominulis ; ocellis inter se quam ab oculis minus distantibus ; 
rostro ad coxas intermedias extenso ; pronoto antice leviter rotundato, inter oculos nonnihil extenso, haud 
carinato, basi leviter sinuato; scutello sat magno equilaterali; tegminibus clavo a corio sutura profunda 
separato; alis vend tertid ante apicem furcaté aream apicalem triangularem formante; pedibus robustis, 
tibiis posticis spinis duabus validis instructis, apice spinoso. 
Oblong-ovate ; head rather large; metopidium very convex and rounded, vertex carinate; eyes nearly round ; 
ocelli distinct, more distant from the eyes than from one another; pronotum nearly twice as broad as 
long, gently rounded in front and slightly produced between the eyes, the base slightly sinuate; scutellum 
nearly equilateral, pointed behind ; tegmina, taken separately, broadly rounded at the apex, the corium 
separated from the clavus by a deep suture; wings with the third vein from the outer marginal vein 
forked and enclosing a somewhat large triangular apical area; legs robust; posterior tibiee with two 
strong sharp spines, the lower one being the longest, and with a strong circle of smaller spines at the 
apex. 
This genus appears to form a transition between the Cercopine and the Ptyeline. 
The species described is in general appearance much like a very small Cercopis. 
1. Negenus varius, sp.n. (Tab. XII. figg. 1; 2, var.) 
Niger, supra haud nitidus, vertice subtiliter rugoso; metopidio nitido ; pronoto sat fortiter rugoso ; tegminibus 
dense et distincte subrugoso-punctatis, maculis duabus ad basin, duabusque pone medium, testaceis vel 
flavo-rufescentibus, variantibus, interdum deficientibus ; pectore piceo-testaceo ; pedibus piceis. 
Black, rather dull above, shining on the underside; vertex finely rugose, subexcavate ; pronotum rather 
strongly, scutellum finely, transversely rugose; tegmina distinctly and very closely rugose-punctate, 
each with an oblong straw-coloured patch at the base, occupying half of the clavus, but not extending to 
the corium, and a round and rather irregular spot behind the middle quite separate from the margins : 
these spots are very variable in size, and are sometimes in part or wholly absent; abdomen black, chest 
pitchy-testaceous ; legs pitchy. 
The chief varieties appear to be as follows :— 
a. Front spots large, straw-coloured ; hind spots moderate, orange. 
6. Front spots much reduced, straw-coloured or orange. 
c, Hind spots much reduced or absent. 
d. Tegmina entirely unicolorous black, without spots. 
Long. 6 millim.; lat. max. 23 millim. 
Hab. Mexico, Jalisco (Schumann), Chilpancingo 4600 feet, Amula 6000 feet, Soledad 
5500 feet, and Xucumanatlan 7000 feet, all in Guerrero (H. H. Smith). 
Aphrophora inclyta and A. maura, Walk., from Sarawak (List of Homopt. Ins., 
Suppl. p. 187), appear to be allied to this species. 
We figure two specimens—one from Soledad and one from Amula.
