CALOPTERON. 9 
Var. a. Elytris pallide flavis, fascia subbasilari marginem non attingente et apice late ceruleis. Long. 13-15 
millim.

(Tab. I. fig. 12.) 
Hab. Type: Mexico, Jalapa (Hége), Vera Cruz (Sallé); Guatemana, Zapote, San 
Gerdnimo, Pancina, San Joaquin, Vera Paz (Champion); British Honpuras, Belize 
(Blancaneaux); Costa Rica, Volcan de Irazu (Rogers). ° 
Var. a: Mexico, Vera Cruz (Sallé); Costa Rica, Caché (Rogers). 
Var. 6: Mexico, Vera Cruz (Sallé); Nicaragua, Chontales (Janson); Costa Rica 
(Mus. Gorham). 
Very nearly allied to dasale, Kirsch. The elytra are clathrate, reticulate ; there are 
four principal nervures; the intervals are divided by longitudinal costules below the 
middle; the outer interval (7.¢. that next the outer margin) is not divided till just 
before the apical blue portion; but individual cells are frequently divided, or the 
transverse lines branch ; towards the apex itself the cellular formation is very irregular ; 
the first, second, and fourth nervures are continued. The portion of the elytra imme- 
diately before the apical blue part is much depressed transversely ; the suture is sinuous ; 
and the elytra in repose overlap. 
This species has been identified by M. Bourgeois with the C. bifasciatum of Dejean’s 
Catalogue. 
The figure 11 is of a specimen from Zapote ; the figure 12 of var. 6 from a Chontales 
specimen. 
2. Calopteron corrugatum. (Tab. II. fig. 3.) 
Calopteron corrugatum, Candéze, Mém. Liége, 1867, p. 357, t. 3. fig. 1. 
Hab, Mexico, Cordova (Sallé, type) ; Nicaragua, Chontales (Belt), San Juan (Sailé). 
This species resembles the var. 0 of C. bifasciatum in colour, but is essentially 
distinct ; the elytra are very slightly depressed, their suture is not sinuous, nor do they 
overlap; the first four interstices are not divided, but single cells are so occasionally. 
The transverse lines vary in the degree of closeness in different specimens. 
The figure is of a Cordova specimen. 
3. Calopteron pallidum. (Tab. I. fig. 14, 2.) 
Nigrum, prothoracis lateribus et elytris pallide flavis, his fascia ante medium indeterminata fusca, illo linea 
mediana nigra; elytris postice spathulato-dilatatis, nervulis quatuor elevatis, interstitiis transversim 
reticulatis, interstitio extimo ad apicem diviso. Long. 16-17 millim. 
Hab. Costa Rica, Caché (Rogers). 
The elytra are very much more dilated before the apex than in the variety of 
palpale, which has a dark fascia; and, as a consequence, the fifth or exterior interstice 
is wider ; and the cells are here divided by a distinct line.
