This species reminds one of Telephorus bilineatus of Say, which is found in the 
United States; it is also not unlike 7. guatemalensis (described hereafter in the present 
work). From the former the pale margins and suture of the elytra, and from both the 
curiously raised black vittee of the thorax (in addition to the male generic characters) 
distinguish it. The crown and base of the head are black and not shining; the 
antennee and terminal joint of both pairs of palpi are black. The thorax has its 
margin finely reflexed, less so in front; it is subquadrate in the male, wider with more 
rounded sides in the female. The elytra exhibit two or three raised lines; but these 
are usually little evident except in the female. Coxe, trochanters, and femora yellow ; 
sometimes the hind thighs are infuscate above. The claws are yellowish. 
21. Discodon oppositipunctum. 
Pallide flavum; prothorace punctis duobus(uno in medio marginis frontalis, altero basali ante scutellum), antennis, 
palpis, tibiis et tarsis, abdominis segmento ultimo elytrisque nigro-fuscis. Long. 7-9 millm. gQ. 
Mas prothoracis disco antice oblique constricto et foveolato, margine vix interrupto; unguiculis posticis fissis. 
Hab. Mexico, Cordova, Toxpam (Sallé). 
_ Head yellow; eyes prominent, especially in the male; antenne greyish fuscous, with 
paler base and articulations. Thorax subquadrate, rounded in front, hind angles right, 
disk uneven ; constricted in the male, and with more prominent hind angles; a small 
spot close to the front margin in the middle, and another on the middle of the base ; at 
times a spot occupying two lateral fovee is faintly visible. Scutellum yellow. FElytra 
greyish fuscous, finely punctured. The legs are yellow, with the exception of the knees 
narrowly black, and the tibie and the tarsi of the same colour. The whole underside 
is yellow, excepting the last segment of the abdomen in both sexes. 
Four specimens are in M. Sallé’s collection. 
22. Discodon purpurascens. (Tab. V. fig. 23, 2 Silis 2) 
Nigrum ; capite et prothorace rufis, hoc vitta mediana, illo occipite nigris ; elytris rufis, subpurpureis, obsolete 
pubescentibus; antennis corpore brevioribus, vix serratis. Long. 10-12 millim. 4g 9. 
Mas prothoracis margine laterali medio oblique minute inciso ; unguiculis anticis internis basi lobatis, inter- 
mediis et posticis externis fissis. 
Hab. Costa Rica (van Patten), Cache (Rogers). 
When I had only seen a single female of this species, which is the specimen 
taken by Mr. Rogers, shown in the Plate, I thought it would prove to be a Stlis; a
