CHELONARIUM. 687 
3. Chelonarium hyphydroide, sp. n. 
Ovale, minus elongatum, parum punctatum, politum, nigricans vel piceum; elytris ad apicem setis depressis 
parum numerosis, ante apicem fascia transversa albido-tomentosa. 
Long. 43-54 millim. 
Hab. Panama, Bugaba (Champion). 
One of the smallest of our species, and of less elongate form than usual, and with 
the punctuation and clothing much reduced. The antennae are moderately long, in 
repose only just falling short of the hind margin of the metasternum. The head has 
a more or less extensive irregular space along the middle free from punctures. The 
thorax is highly polished, the front margin is but little reflexed, and the punctua- 
tion is obsolete in the hollow, and absent on the elevated, portion, and the sete in the 
punctures are excessively minute. There are some white hairs on the scutellum. The 
punctuation on the parts of the elytra anterior to the white band is extremely fine and 
distant, and the hairs proceeding from the punctures very small; on examination under 
a microscope it is seen that, on the front parts, each puncture really consists of two fine 
approximate punctures placed longitudinally, the fine seta proceeding from the anterior 
one of the pair. The white postmedian band varies in size and is sometimes reduced 
to a few hairs; behind it, the sete are more distinct than those at the base, but though 
long they are very distant, and the sculpture is extremely fine. The punctuation of 
the under surface is much reduced, the ventral segments being almost smooth on a broad 
space along the middle; the plates of the hind coxe are only finely punctate, shining, 
and there is but little punctuation on the metasternum. EHighteen specimens. 
4, Chelonarium errans, sp. n. 
Ovale, elongatum, parum punctatum, nigricans vel piceum; elytris ad apicem setis depressis elongatis, parum 
numerosis, ante apicem fascia transversa albido-tomentosa. 
Long. 54-6 millim. 
Hab. GUATEMALA, Zapote (Champion); Panama, Volcan de Chiriqui below 4000 feet 
(Champion). 
This species is very closely allied to C. hyphydroide, but is of more elongate form, 
and is easily distinguished by the greater length of the sete, a character which becomes 
very marked on the apical part of the elytra. The sete are also yellower in colour, the 
surface is rather less polished, and the punctuation of the under surface is not quite 
so obsolete. ‘Thirty-three specimens. There is little or no difference between the 
individuals from Chiriqui and those from Guatemala. 
5. Chelonarium chiriquense, sp. n. 
Ovale, rufescens ; elytris parce setosis, guttisque albidis hic inde sparsis, ante apicem in fasciam transversam 
imperfecte aggregatis ; corpore subtus modice punctato ; antennis parvis. 
Long. 5-53 millim.
