HEMIPTERA-HETEROPTERA. 309 
Var. calderensis. 
This variety differs from that described under the name of panamensis by having the posterior tibize more 
regularly widened, not notched or sinuated outwardly near base. 
Long. 35 millim. 
Hab. Panama, Caldera (Champion). 
Acanthocephala granulosa (p. 120). 
Acanthocephala luctuosa, huj. op. p. 120. 
To the localities given, add :--Mrxico, Presidio de Mazatlan in Sinaloa, Ventanas in 
Durango (forrer), Tepic in Jalisco (Schumann), Cuernavaca in Morelos (H. H. Smith), 
Omealca (MM. Trujillo), Orizaba (H. H. Smith & F. D. G.), Misantla and Jalapa (F. D.G.), 
Amula, Chilpancingo, Omilteme, Rincon, Tierra Colorada, Venta de Pelegrino, all in 
Guerrero, Teapa in Tabasco (H. H. Smith), Temax in North Yucatan (Gaumer) ; 
GuaTEMALA, Panzos (Conradt), Lanquin and Senahu (Champion). 
From the examination of a long series of specimens obtained from different localities 
in Mexico, in which the shape of the posterior tibiz of both sexes and the colour of the 
antenne are of the most variable character, 1am now inclined to consider the A. granu- 
losa, Dall., and the A. luctwosa, Stal, as but different forms of one species. The 
variation is also of such an intermittent character that I cannot—with the present 
abundant material—separate Stal’s form as a constant variety, though we have already 
figured it in its typical appearance. 
Acanthocephala bicoloripes (p. 120). 
To the localities given, add:—Panama, Caldera, Volcan de Chiriqui 2000 to 4000 
feet (Champion). 
STENOSCELIDEA (p. 121). 
Stenoscelidea snescens (p. 121). 
To the localities given, add :—Mexico, Acaguizotla, Rincon and R. Papagaio, all in 
Guerrero, Teapa in Tabasco (H. H. Smith). 
LAMINICEPS. (To follow the genus Stenoscelidea, p. 121.) 
Laminiceps, Costa, Rendic. Accad. Napol. ii. p. 250 (1863) ; Stal, Ofv. Vet.-Ak. Forh. 1867, p. 542. 
Junia, Stal, Ann. Soc. Ent. Fr. sér. 4, v. p. 179 (1865). 
Differs from Stenoscelidea by the non-dilated posterior tibie. 
This is another purely neotropical genus consisting of some half-dozen species. 
Nicaragua is, according to our present knowledge, the most northern limit of the 
genus.
