CYMATODERA. 131 
Thorax narrower behind than in front, widened on the sides in the middle, much 
compressed laterally below the widest part, the disk finely wrinkled transversely above ; 
elytra parallel, apex rounded; sutural angle nearly closed, without strie, but with 
punctures in series, of which there is one sutural, then four pairs of gemellate series, 
very obsolete in the female from Sturm’s collection—closer and more regular in three 
examples which are, I believe, males of the same species. The male has the apex of 
the pygidial plate canaliculate, the fifth ventral plate widely emarginate, with a carina 
from each side of the excision. 
This species appears to me to be allied to C. discoidalis, Chevr., but to be distin- 
guished from it by being more parallel, by the more indeterminate fuscous markings of 
the elytra, which are also less pointed at their extremity. 
4, Cymatodera discoidalis. (Tab. VII. fig. 10, var. fig. 15, 
Cymatodera discoidalis, Chevr. Mag. Zool. 1843, p. 10°. 
Hab. Mextco!, Jalapa, Oaxaca, Cerro de Plumas (Hége). 
This insect, of which the unique type has most obligingly been sent to me by 
M. A. Chevrolat, is less parallel than the preceding; the elytra are more coarsely 
punctured at their base, and have a distinct fuscous patch at two thirds, squarish, with 
its diagonal formed by the suture. The elytra are widest at the centre of this patch, 
and are rather hairy. In a male specimen from Cerro de Plumas the fifth segment is 
arcuately excised, the sixth spoon-shaped, broadly rounded at the apex, and closely 
punctured. A series of this species was collected at Oaxaca and Jalapa, and two or 
three at Cerro de Plumas, by Hoge. 
The type specimen is a female, and perfectly accords with a specimen from Oaxaca, 
except in being a little less deeply coloured. 
5. Cymatodera championi. (Tab. VII. fig. 12, ¢.) 
Elongata, subcylindrica, picea nitida, parce pilosella; prothorace fere glabra; elytris profunde seriatim punc- 
tulatis, apice subtruncatis; antennis longis, caput et prothoracem superantibus ; pedibus dilutioribus. 
Long. 16 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Head considerably wider than the thorax ; antenne long, rather longer than the total 
length of the head and thorax together in the male, in the female about equal in 
length. Prothorax very smooth and shining, wider in front than at the base, all the 
usual prominent parts rather strongly pronounced. The elytra in the male are more 
parallel and narrower than in the female, with series of large deep punctures, which 
are placed rather near together, and at equal distances from each other. The body. 
beneath is pitchy black in the male; in the female it is rufous at the apex and sides of 
the two last segments but one. The legs are pitchy black in the male, pitchy red in
