136 MALACODERMATA. 
Elytra parallel, evenly rounded at their apex, regularly and deeply punctate-striate, 
strie vanishing at one sixth before the apex; pitchy brown, in the middle a rather 
oblique pale fascia, and the apex rusty red for one quarter the length of the elytron. 
The male has the fifth ventral plate emarginate, the sixth an oblong truncate piece 
notched at its extremity and thickened on the sides, with a corresponding pygidial 
plate; the seventh or genital a bifid acute organ, like two lancets slightly recurved ; 
this piece is often wanting, when the apex of the sixth plate only remains. The 
female has the sixth plate obconic, the apex rounded, with a deep impression on 
its ventral side. 
This fine species, one of the largest of the genus, is most nearly allied to C. fasciifera, 
Lec., of the species known to me, from which it differs inter alia in being less pubes- 
cent, in having the legs almost entirely pale, the apex broadly ferruginous, &c. 
Four specimens have occurred at Trapiche, and as many at Jalapa; in Guatemala 
only one each at the two localities named, which are smaller and slightly different in 
the punctuation, but are, I believe, specifically the same. 
17. Cymatodera flexuosa. 
Rufo-ferruginea, nitida ; prothoracis lateribus piceis; elytris depressis, postice ampliatis, flavis, basi seriatim 
parce punctatis, plaga subhumerali lituraque subapicali piceis. Long. 12 millim. 9. 
Hab. Mexico, Orizaba (Sallé). 
The single specimen there is of this is apparently of a very distinct species. The 
elytra are widened and flat above, but it is amply winged. 
The head and thorax very finely and obsoletely punctured and wrinkled, pitchy red, 
darker between the eyes and on the sides of the latter. ‘The elytra are shining, yellow, 
with pitchy punctures; there is a stripe on the sides below the humeral callus, and a 
broad, rather crescent-shaped mark meeting the margin in the apical half; the punctures 
are small, distant, neatly arranged in rows in the basal half, only a very few passing 
beyond the middle. The legs and underside wholly ferruginous. The antenne are 
half the body’s length, with the palpi and epistoma rusty red. 
18. Cymatodera marmorata. (Tab. VII. fig. 14.) 
Cymatodera marmorata, Klug, Abhand. Berl. Acad. 1842, p. 271, nec Spinola, Mon. Atlas, t.9. f. 4. 
Hab. Mexico, Catemaco (coll. Sallé). 
The specimen figured is a single example so named in the Sallé collection, on what 
authority I know not. It belongs to the “angustata” section, which have the elytra 
oval, widest behind the middle. The thorax is very long, thickly and distinctly punc- 
tured. The legs are pale, with the exception of the femora, which are strongly clavate 
and dark in their apical half.
