172 HEMIPTERA-HOMOPTERA. 
Hab. Panama (Boucard), Volcan: de Chiriqui 2000 to 3000 feet (Champion).— 
Cotomsia 15, Bogota !®; Bouivia #2; Braziu}4. 
Numerous examples. This insect is, no doubt, nothing but a small variety of 
4h, reticulatum, with the apex of the elytra, as a rule, somewhat more strongly 
reticulate. |

2. Aithalion nervoso-punctatum. (Tab. X. figg. 20, 20a.) 
AEthalion nervoso-punctatum, Sign. Ann. Soc. Ent. Fr. sér. 2, ix. p. 679, t. 14. figg. 10, 10@°. 
Hab. Mexico! (Sallé; Mus. Oxon.), Ciudad in Durango 8100 feet (Forrer). 
This is a very distinct, dull brownish species, which may at once be known by the 
dark spots on the testaceous veins of the tegmina, the head and pronotum being 
similarly spotted. 
Var. M1nor, var.n. (Tab. X. fig. 21.) 
Forme typicali affinis, sed multo minor, colore griseo-testaceo, margine posteriori capitis magis sinuato, venis 
tegminum minus distincte fusco-maculatis, basique horum minus late opaca. 
Allied rather closely to the type-form, but of a more griseous colour, with the posterior margin of the head 
more sinuate in the middle, the pronotum a little shorter in proportion and more declivous, and the veins 
of the tegmina less distinctly marked with fuscous (this, however, is a variable character); the base of 
the tegmina is less broadly opaque and punctured. 
Long. cum tegm. 7 millim.; lat. int. hum. 3 millim. (Long. form. typ. 84-9 millim. ; lat. 4 millim.) 
Hab. Mexico, Omilteme 8000 feet, and Xucumanatlan 7000 feet, both in Guerrero 
(H. H. Smith). 
It is possible this may hereafter be regarded as a separate species, but I believe that 
it is only a local variety. 
° 3, Aithalion quadratum, sp.n. (Tab. X. figg. 22, 22c.) 
Oblongum, griseo-testaceum, capite angustiori ; margine posteriori leviter sinuato, pronoto scutelloque immacu- 
latis, illo distincte, hoc subtiliter punctato ; tegminibus venis crassis brunneis, sine maculis, areis apicem 
versus plerumque quadratis ; pedibus obscure testaceis ad partem leviter indistincte infuscatis. 
Oblong, subparallel, of a griseo-testaceous colour, with the head narrow, slightly but plainly sinuate on its 
posterior margin ; pronotum and scutellum without spots, the former distinctly and moderately strongly, 
and the latter very finely, punctured; tegmina punctured at the base, with the veins very distinct and 
raised, and the apical areas more regular and quadrate than in the allied species ; legs dark testaceous, 
in part obscurely infuscate. — 
Long. cum tegm. 64-7 millim. ; lat. int. hum. 3 millim. 
Hab. Panama, Volcan de Chiriqui 4000 to 6000 feet (Champion). 
This seems to be a very distinct species, although it is allied to the var. minor of 
LE. nervoso-punctatum ; in both these insects the pronotum is more declivous in front 
than appears to be usual with members of the group, and thus causes them to approach 
nearer to the true Membracide. The specimens described are females.
