2. Arescus perplexus. (Tab. II. figg. 12, 13.) 
Arescus perplexus, Baly, Cat. Hispide, p. 84° (nec Waterh.). 
Var. A. Subtus fulvo-piceus, piceo variegatus; supra fulvus; antennis extrorsum nigris ; elytris piceo-punc- 
tatis, utrisque macula parva humerali alteraque discoidali, vix ante medium posita, nigris, neo vix 
micantibus. 
Hab. Costa Rica (Van Patten).—Cotomsta ! (type, coll. Baly). 
This species, which probably is as variable as most of its congeners, is appa- 
rently rare, only two specimens (the typical one from Colombia and a second from Costa 
Rica) being known to me. The specimen from Costa Rica differs from the type in 
having the sides of the thorax obliquely converging ; in all other respects (except colour) 
it agrees with the typical form. A. perplexus may be at once separated -from its allies 
by the angular apices and deep punctuation of the elytra. 
Owing to this species having been accidentally omitted from Gemminger and Harold’s 
Catalogue, Mr. C. O. Waterhouse has since described another insect under the same name. 
CEPHALODONTA. 
Cephalodonta, Baly, Cat. Hispide, p. 124, t. 2. f. 15. 
Twenty-two species of this genus are described or enumerated below; of this number 
four only were previously known. 
Mr. Champion informs me that most of the species are found sitting upon leaves, 
some in the dense forest, others in the thinly-wooded savanna country ; they are more 
numerous in the “tierra caliente” than at the higher elevations. 
1. Cephalodonta gemmans. (Cephalodonta generosa*, Tab. II. fig. 14.) 
Anguste oblonga, convexa, nitida; subtus nigro-picea aut nigra; supra viridi-enea; capite granuloso, nigro- 
geneo aut eneo, facie inferiori antennisque piceo-fulvis, his filiformibus, ad apicem paullo incrassatis, 
articulis sexto et septimo flavis, ultimis quatuor nigris; thorace quam lato longiori, subcylindrico, crebre 
foveolato-punctato, basi et apice piceo-fulvo marginato; elytris oblongis, lateribus vix ante medium con- 
strictis, pone medium paullo ampliatis, apice subacute rotundatis, ad suturam leviter emarginatis, convexis, 
seriatim punctatis, tuberculis aut cretis oblongis octo aut novem quadriseriatim dispositis instructis, viridi- 
eeneis, basi nec non sutura piceo-fulvis, limbo exteriori flavo, eneo tincto. 
Long. 14-2 lin. 
Hab. Guatemaua, Cerro Zunil 4000 to 5000 feet, Las Mercedes 3000 feet (Cham- 
pion). 
Head finely granulose, vertex impressed with a deep longitudinal groove; front 
produced just above the insertion of the antenne into a short triangular plate. Antenne 
half the length of the body, filiform, slightly thickened towards the apex; joints cylin- 
drical, the basal one short, submoniliform, second slightly longer, subovate, the third, 
* On the Plate the name of this species is wrongly given as Cephalodonta generosa, a name already employed 
by Guérin for a species of the same genus.
