LEPYRONIA.—APHROPHORA. 193 
Superficially, this species, which is not represented in our collection, bears a strong 
resemblance to Philenus fusco-varius, Stil. Iam not quite sure whether it would not 
be better to separate it from Lepyronia; but, as I have only seen one specimen 
(presented by Stal to Signoret and now in the Vienna Museum), I do not feel competent 
to do more than pronounce an opinion. The wings appear to answer to Stal’s description 
of the genus, but the form is quite different from that of the ordinary species of 
Lepyronia. 
PHILAENUS. 
Philenus, Stal, Stett. ent. Zeit. 1864, p. 66 ; Hemipt. Afr. iv. p. 68 (1866). 
This genus differs from Aphrophora in having the vertex of the head and the 
pronotum without carine, and in having the third vein from the outer marginal vein 
forked at some distance from the apex and forming an apical area, which is distinctly 
rounded at the fork. 
1. Phileenus fusco-varius. (Tab. XII. figg. 5; 6, var.) 
Philenus fusco-varius, Stal, Stett. ent. Zeit. 1864, p. 66°. 
Hab. Mexico (Mus. Holm. & coll. Signoret'), Pinos Altos in Chihuahua (Buchan- 
Hepburn), Omilteme 8000 feet, Chilpancingo 4600 feet, and Xucumanatlan 7000 feet, 
all in Guerrero (H. H. Smith), Orizaba, Cuernavaca, Jalapa (Bilimek, in Mus. Vind. 
Ces.); GuateMALA, Chiacam in Vera Paz, Quiché Mountains 7000 to 9000 feet, 
Panajachel 5000 feet, Capetillo (Champion). 
The specimens in our collection are variable in size and coloration: one, from the 
Quiché Mountains, is only 5 millim. in length; and one, from Omilteme, has a large 
whitish dorsal patch covering the greater part of the basal half of the tegmina. 
We figure a specimen from Pinos Altos, and a variety from the Quiché Mountains. — 
APHROPHORA. 
Aphrophora, Germar, Mag. Ent. iv. p. 48 (1821); Burmeister, Handb. Ent. ii. p. 121; Amyot et 
Serville, Hist. Nat. des Ins. Hémipt. p. 563. 
The insects belonging to this genus have the vertex and pronotum plainly carinate, 
and the third vein from the outer marginal vein, as a rule, forked, the fork enclosing an 
apical area, which is more or less rounded at the apex. This last-mentioned character, 
however, is variable: in one species, which appears undoubtedly to be an Aphrophora, 
the fork is absent or slightly represented on one side only. The posterior tibie are 
robust, with two very strong spines, and with the crown of spiacs at the apex strongly 
marked.
