MALACODERMATA. 285 
have a small seventh ventral plate, and appear to me to be males and to pertain to 
Leconte’s Section A (Brachynotus, Kirby), the tooth of the claw not being so long as 
the claw itself, but acute and adjacent. 
DISCODON (p. 78). 
Discodon erosum (p. 79). 
To the localities given, add:—Panama, Volcan de Chiriqui 2000 to 3000 feet 
(Champion). 
Two specimens occurred: these differ a little from the type in the colour of the tibie, 
which are pale at the base; the antenne likewise have some of the apical joints 
ochreous in one of these examples. 
Discodon plicatum (p. 79). 
To the localities given, add:—Mexico, Cordova, Jalapa (Hége); GuatTeMALa, Las 
Mercedes, El Tumbador (Champion). 
2 (a). Discodon ——? 
Hab. Mexico (Sturm, coll. Sallé). 
A single female specimen of a large species somewhat allied to D. plicatum, but 
larger and opaque; the thorax transverse and white, and with a wide black vitta. It 
is labelled ‘‘ Canth. albolateris, mihi,” in the Sallé collection. 
2 (s). Discodon calidum. 
Lividum, nitidum ; capitis vertice, antennis, palpis, thoracis vitta integra, scutello, abdomine, geniculis, tibiis 
tarsisque nigris. Long.13 millim. ¢ Q. 
Mas. Prothoracis margine laterali medio plicato-interrupto, segmento septimo ventrali fisso. 
Femina. Antennis articulis tribus ultimis lividis ; prothoracis margine laterali medio leviter sinuato, 
Hab. Panama, Volcan de Chiriqui (Champion). 
A large species, at first sight very similar toa variety of Sidis varians, but larger, and, 
of course, to be separated by the males having the outer claws of the front tarsi with a 
laminar tooth-like extension and those of the middle pair bifid. The three terminal 
joints of the antenne in the male are fuscous. 
Four examples, one male and three females, were collected by Mr. Champion. 
Discodon carbonarium (p. 80). 
Var. Thorace obscure rufo, disco nigrescente. 
Hab. Guatemata, Quiche Mountains, Cerro Zunil (Champion). 
The prothorax in this species has a wide shallow depression behind the middle. The 
elytra are rather shining, scarcely visibly sculptured.
