PELONIUM. 189 
the thorax are more diffused and the hinder ones confluent; but in other respects this 
insect seems to agree with the figure. 
5. Pelonium amabile. (Tab. IX. fig. 15.) 
Pelonium amabile, Spin. i. p. 862", t. 33. f. 1; Chevr. Rev. et Mag. Zool. 1874, p. 26°. 
Hab. Panama, Volcan de Chiriqui (Champion).—Soutn America, Colombia *, Guiana, 
Cayenne, Brazil ?. 
The scutellum, club of the antenne (excepting the tip of the apical joint), and three 
joints preceding it are pitchy black. The elytra are vaguely and very obsoletely 
punctured. 
Only one specimen was met with by Champion. 
6. Pelonium percomptum. 
Precedente angustius ; prothorace longiore, ad basin utrinque linea nigra; elytris pallidis, scutello concolori, 
fortiter striatim punctatis, singulis postice macula irregulari obliqua, versus apicem convergente, rufo- 
testacea nigro marginata ornatis ; pedibus pallidis, geniculis, femoribus medio clavisque articulis apicibus 
nigro tinctis. Long. 83 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
This species is a good deal like P. amabile, but differs in many respects, particularly 
in the large punctures of the basal part of the elytra (the apex from the posterior 
patch onwards is smooth) and in the form of the brownish-red patch behind: in 
P. amabile it is irregularly quadrate, common to both elytra; here it is separate on 
each elytron, though meeting near the apex, oblique, externally with two notches, the 
first forming a sinus. The apex of the antenne is dark here, but pale in P. amabile. 
A single specimen only, sent by Champion. 
7. Pelonium metallescens. (Tab. IX. fig. 16). 
Subdepressum, oblongum, elytris subparallelis; supra eneo-plumbeum micans, capitis fronte, prothoracis lateribus 
angustius pedibusque pallide flavis, his fusco variegatis, capite thoraceque profunde et rugose punctatis. 
Long. 6 millim. 
Hab. Guatema.a, Cerro Zunil (Champion). 
Head testaceous, tips of the mandibles and of the palpi and crown pitchy; antenne 
ten-jointed, of which the fourth and sixth joints are triangular and larger than the 
fifth, the seventh joint is small and almost quadrate, the three club-joints subequal. 
The thorax is pitchy above, with an impression on each side immediately above the 
tubercles (which are yellow) ; and there is an obsolete fossa on each side of the central 
line at the base. The elytra have very indistinct indications of strie; they are shining 
with a brassy tint. ‘The legs are very pale, with the knees, a spot in the middle of each 
tibia, and the tarsi clouded. 
Three specimens from Cerro Zunil.
