CALOPTERON. 11 
A widely dispersed and very variable species, with which very probably one or two 
more of the following forms will have to be united. 
The figure is of a specimen from San Gerénimo. 
8. Calopteron serratum. 
Lycus serratus, Linn. Syst. Nat. i. 2, p. 649°. 
Lycus serratus, Ol. Ent. ii. 29, t. 1. fig. 5. 
Hab. Guatemata, Zapote (Champion); Nicaracua, Granada (Sallé), Chontales 
(Janson, Belt)—Souta America, Cayenne}. 
Apparently the only distinction between this species and C. reticulatwm is the com- 
bination of a yellow body with a black scutellar patch, and the greater or less inden- 
tation of the black apical portion at the first costal nervure. 
9. Calopteron jimenezi. 
Calopteron jimenezi, Duges, La Naturaleza, 1878, iv. p. 181, t. 6. fig. 8. 
Hab. Mexico, Guanajuato (Sallé). 
10. Calopteron flavipes. (Tab. I. fig. 18, 2 .) 
Calopteron flavipes, Blanch. Voy. d’Orb. Ent. p. 126°. 
Hab. Guarema.a, Zapote (Champion).—Bo.tvia'. 
The body, scutellum, legs, thorax, and base of the antenne are yellow; the sides of 
the abdomen, tarsi, and disk of the thorax are slightly infuscate. 
This species and the three preceding it agree closely in form and sculpture; they 
differ in characters which, though tolerably constant when specimens from one locality 
are examined, will, I believe, prove illusive when tested by series from intermediate 
places. | 
11. Calopteron divergens. (Tab. II. fig. 4, 3.) 
Nigrum, trochanteribus, femoribus basi, prothorace (linea mediana excepta), elytrorum basi et fascia in medio, 
postice dentata, flavis ; elytris obcordiformibus, ad apicem valde expansis divergentibus. ¢ 2. 
Mas brevior, elytris ad apicem fortiter distantibus. Long. 10-12 millim., lat. max. 10 millim. 
Femina elytris minus expansis vix distantibus. Long. 15 millim., lat. max. 9 millim. 
Hab. Nicaracua, Chontales (Janson). 
A species or race differing so remarkably from all other forms of reticulatum in the 
short obcordate form of the elytra, and in their divergence at the sutural angle, that it 
seems more worthy of a specific name than some others. In addition to this character, 
the black portion of the thorax is reduced to a narrow line, its margins are very much 
yeflexed, and its posterior angles acute. The elytra have no scutellar patch ; the hind 
margin of the yellow fascia is dentate on the second nervure and produced a little on
