CODEEA MEGALOPS, n. sp. Elougata, capita magno, cum oculis 
thorace latiori; hoc quadrato, laterihm antice angulatis, dein sinuato- 
angustatis, angulis posticis rectis ; corpore mhtus, pedibus, capite 
thoraceque viridi-ceneis , elytris violaceo-cnpreis, oblongis, sinuato- 
truncatis, angulis externis dentiformihus, suturalihus spinosis, supra 
profunde punctato-striatis, fasciis duabus macularibus testaceis ; 
antennis obscure piceis, articulis basalibus csneis. 
Long. 71—11 milli7n. Lat. elytr. 24—31 millim. ? . 
Distinguished by the very prominent eyes, which make the head wider than 
aroadest part of the thorax, in this respect resembUng C Schaumii (Chand.) 
, Costa Rica. The under-surface of the body, femora, parts of the mouth and 
,1 joints of the antenna} are dark brassy-green; the head and thorax of a more 
iant green, the head with five or six sharp furrows on each side near the eyes ; 
thorax is nearly as long as broad, and is remarkable in not having the sides 
ided, but produced into a distinct angle, not far from the front margin, and 
ewhlt sinuated both before and after the angle. The labrum is sharply notched 
;8 front edge and is of a brassy-black hue. The elytra are sinuate-truncate, 
1 the lateral angles of the truncature produced into a broad sharp tooth, and 
sutural angles into a narrow spine ; the pale belts are formed of linear spots ; 
anterior belt of six, all short, except that on the 4th interstice, which is four 
es the length of any of the others, and the posterior belt of seven (not including 
indistinct spot on the sutural interstice), all of moderate length. 
Ega and Lower Amazons ; in the rotting and broken bark of the 
aglis of larg: trees, especially in places where these lie across each 
ler, where the species sometimes occurs in plenty. C. megalops 
fers from C Schaumii {bifasciata, Schaum, Berl. Ent. Zeits., 1860, 
iii, p. 4), in the richer violaceous-copper hue of the elytra, the 
aen'ce of green tinge towards the base, and of the additional yellow 
ot near the base on the 5th interstice, besides other characters. 
Besides the numerous species above recorded, the following 
scribed species occur in the Amazon region : — 
G. luculenta, Erichs., Consp. Ins. Peru, p. 69. Common at Eg:i. 
G. picea, Uej., ii, p. 458. Generally distributed throughout the 
luntry, but rare. 
Genus Stenoglossa, Chaudoir. 
This genus was founded by Baron Chaudoir on certain very small 
optodera forms, chiefly on account of their having a very long and 
arrow ligula, with elongate paraglossae convergent at their extremities. 
In dissecting St. dromioides, I find his description accurate, but do 
ot see that these organs differ essentially from those of several true 
hptoderce. The meutum, however, difters from them, in being much
