Cqptodeka megalops, n. sp. Elongata, capite magno, cum doulis 

 thorace latiori; hoc quadrato, lateribus antice angulatis, dein sinuato- 

 angustatis, angiitis posticis rectis ; corpore subtus, pedibus, capite 

 thoraceque viridi-ceneis, elytris violaceo-cupreis, oblongis, sinuato- 

 truncatis, angulis externis dentiformibus , suturalibus spinosis, supra 

 profunde punctato-striatis, fasciis duabus macularibus testaceis ; 

 antennis obscure piceis, articulis basalibus ceneis. 



Long. 7^- — 11 millim. Lat. elytr. 2f — 3| millim. ? . 



Distinguished by the very prominent eyes, which make the head wider than 

 the broadest part of the thorax, in this respect resembling Q. Schaumii (Chaud.) 

 from Costa Rica. The under-surface of the body, femora, parts of the month and 

 basal joints of the antenna? are dark brassy-green ; the head and thorax of a more 

 brilliant green, the head with five or six sharp farrows on each side near the eyes ; 

 the thorax is nearly as long as broad, and is remarkable in not having the sides 

 rounded, but produced into a distinct angle, not far from the front margin, and 

 somewhat sinuated both before and after the angle. The labrum is sharply notched 

 in its front edge and is of a brassy-black hue. The elytra are sinuate-truncate, 

 with the lateral angles of the truncature produced into a broad sharp tooth, and 

 the sutural angles into a narrow spine ; the pale belts are formed of linear spots ; 

 the anterior belt of six, all short, except that on the 4th interstice, which is four 

 times the length of any of the others, and the posterior belt of seven (not including 

 an indistinct spot on the sutural interstice), all of moderate length. 



Ega and Lower Amazons ; in the rotting and broken bark of the 

 boughs of largo trees, especially in places where these lie across each 

 other, where the species sometimes occurs in plenty. C. megalops 

 differs from G. Schaumii (bifasciata, Schaum, Berl. Ent. Zeits., 1860, 

 pi. iii, p. 4), in the richer violaceous-copper hue of the elytra, the 

 absence of green tinge towards the base, and of the additional yellow 

 spot near the base on the 5th interstice, besides other characters. 



Besides the numerous species above recorded, the following 

 described species occur in the Amazon region : — 



O. luculenta, Erichs., Consp. Ins. Peru, p. 69. Common at Ega. 



C. picea, Dej., ii, p. 458. Generally distributed throughout the 

 country, but rare. 



Genus Stenoglossa, Chaudoir. 



This genus was founded by Baron Chaudoir on certain very small 

 Coptodera forms, chiefly on account of their having a very long and 

 narrow ligula, with elongate paraglossaa convergent at their extremities. 

 On dissecting St. dromioides, I find his description accurate, but do 

 not see that these organs differ essentially from those of several true 

 Coptoderce. The mentum, however, differs from them, in being much
