188 MALACODERMATA. 
1. Pelonium stenochioides. 
Pelonium stenochioides, Chevy. Rev. et Mag. Zool. 1874, p. 74°. 
Hab. Mexico}. 
M. Chevrolat (Mémoire, p. 37) says this and his P. semivittatum are allied species. 
The latter=P. helopioides, Cast. 1 have not seen it. 
2. Pelonium nigroclavatum. 
Pelonium nigroclavatum, Chevy. loc. cit. p. 75}. 
Hab. Mexico, Teapa in Yucatan ! (Pilate). 
Apparently not unlike the species which follows; Chevrolat compares it with his 
piciventre from Cuba described in the same paper. 
3. Pelonium notabile. 
Subparallelum, punctatum, rufo, piceo pallidoque variegatum ; prothorace inequali, tuberculis elevatioribus 
rufo-piceis, postice nigro-piceo; elytris unicostatis, pallidis, punctis piceis maculisque nigris adspersis, 
fascia irregulari ante apicem rufo-picea, ad suturam latiore, nigro marginata, apice subalbido levi ; 
antennis pallidis, articulorum penultimorum duorum apicibus et ultimi medio nigris; pedibus anticis 
nigro-piceis, basi tarsisque fulvis, posticis et intermediis pallidis, geniculis tibiisque externe nigro tinctis. 
Long. 8-9 millim. 
Hab. Panama, Bugaba (Champion). 
A beautiful species, but difficult to describe: it reminds one of P. scopariwm, Klug ; 
but its surface is more uneven, and its colours are different. The head is pitchy black 
in front, rufous behind, with two darker lines, one from each eye to the base; it is 
sparingly but distinctly punctured behind; the eyes are coarsely granulate, the antenne 
rather longer than head and thorax, the club equal to basal portion, last two joints 
but one triangular. The thorax is longer than wide, with a central short sulcus, 
and a pit on each side of the centre surrounded by rufous elevated but irregular 
and confluent tubercles; the sides are tubercularly widened. The elytra are very 
coarsely punctured, the punctures honeycomb the surface; the costa reaches the sub- 
apical fascia; the yellowish-white apical patch is unpunctured. 
Four specimens are all that have been sent.

Pelonium fasciculatum, Spin. Atlas, t. 36. f. 3. 
Hab. Panama, Bugaba (Champion).—Sovutn America!, Brazil (coll. Gorh.), Magellan}. 
The identification is not certain; but the specimen from Brazil in my own collection 
is certainly the same as the single one collected by Champion. The apical joint of the 
antenne is yellow. The thorax is smooth, with small lateral tubercles; the spots on
