the suture. The second and fourth nervures are costate, the first and third lie in the 
valley between. The black fascia shows a tendency to become obsolete, in the females 
especially, in one specimen of which it is reduced to two spots. ‘The underwings are 
ample. | 
12. Calopteron scapulare. (Tab. I. fig. 25; Tab. II. fig. 5, ¢ .) 
Nigrum, prothorace (disco excepto) elytrisque ad humeros plus minusve sordide rufis. Long. 6-9 millim. ¢ 9. 
Hab. Mexico, Vera Cruz (Sallé); Guatemaua, Zapote, La Tinta, San Juan, and Vera 
Paz (Champion). 
The small size, moderately dilated form, obscure blackish colour, with shoulders more 
or less yellowish red, and thorax transverse, with acute hind angles and well-marked 
carina, will enable one to recognize this species. The elytra are more suddenly 
dilated, and more rounded at the apex in the male. The second and fourth nervures 
are costate. 
This little Calopteron was taken in considerable numbers by Mr. Champion at Zapote. 
It stands in Parisian collections under the name C. scapularis, and was so named for me 
by M. Bourgeois. 
The figures are from Zapote specimens. 
13. Calopteron posticum. 
Calopteron posticum, Kirsch, Berl. Zeit. 1870, p. 8378; Bourg. Ann. Soc. Ent. Fr. 1879, p. 291. 
Nigro-piceum, capite, prothorace, pectore, pedibus anticis elytrisque testaceis, his fascia ante medium, ad 
suturam latiore, apiceque nigro-fuscis; prothorace subquadrato, valde carinato, angulis posticis acutis, 
productis. Long. 7-8 millim. 
Hab. Nicaracua, Chontales (Janson); Panama, Matachin (Thieme).—Co.omBta’. 
A few specimens only of this have been received from Chontales. It is rather more 
depressed than C. scapulare; the head is frequently infuscate on the crown, as are also 
the tips of the palpi. All the tarsi, and often the anterior legs, are dark, excepting at 
the base. The dark fascia of the elytra is usually interrupted by the yellow suture 
and costate nervures, and is often nearly obliterated. It is very nearly allied to the 
following species; but the antenne appear to me to be longer. Mr. Oberthir has 
communicated to me a fine series of this species taken by Dr. Thieme in Panama. 
14. Calopteron juvenile. (Tab. I. fig. 16.) 
Calopteron juvenile, Bourg. Comptes Rendus Soc. Ent. Belgique, 1879, p. xvi. 
Hab. Costa Rica (v. Patten), Caché (Rogers). 
Very like the last species, but darker in colour, the antennz scarcely so long as the 
elytra, and with only a shoulder-spot of yellow at the base. The central yellow fascia 
is usually neatly and distinctly defined. The thorax is similar in form to that of 
C. posticum, with acute produced hind angles.
