DIBELONETES. 603 
§2. Thorax more developed, always broader, usually longer, with the lateral angles not 
altogether obliterated ; right mandible tridentate, the superior tooth only slightly 
prominent (Sunides). 
3. Dibelonetes pallipes. 
Nigerrimus, antennis, palpis pedibusque pallide flavis; elytris minus opacis, crebre fortiter profundeque 
punctatis. 
Long. 5 millim. 
Hab. GuatemMaLa, Cubilguitz in Vera Paz (Champion); Nicaragua, Chontales 
(Janson). 
Antenne long and slender, the terminal joints a little thicker. Labrum with two spines 
in the middle, and a minute sharp denticle on either side; right mandible tridentate, 
the left bidentate. Head suboblong, but a little constricted in front of the eyes, and a 
little narrowed behind these to the vertex, rather coarsely reticulate-strigose. Thorax 
elongate, considerably longer than broad, a little narrowed behind and more so in front, 
coarsely sculptured, towards the sides rugose and obsoletely impressed. Elytra con- 
siderably longer than the thorax, rather deeply and coarsely punctate. Hind body 
indistinctly punctate. Legs very pale yellow, rather stout. The male has the hind 
margin of the last ventral] segment broadly but slightly emarginate. 
Two examples from Guatemala, one from Nicaragua. 
4. Dibelonetes laticeps. (Tab. XV. fig. 21.) 
Nigerrimus, opacus, cinereo-pubescens, dense punctatus ; antennis, palpis pedibusque pallide flavis, elytrorum 
apice omnino angustissime testaceo signato. 
Long. 5 millim. 
Hab. Panama, Bugaba, San Feliz (Champion). 
Antenne slender, rather long, a little thicker externally; penultimate joint only a 
little longer than broad. Head broad, slightly broader than the elytra, a little narrowed 
behind the convex eyes, the vertex truncate; densely reticulate-strigose. Thorax elongate, 
much longer than broad, gently narrowed behind, more abruptly so in front, densely 
sculptured. Elytra a little longer than the thorax, densely punctate, the outer apical 
angle of each with a small transverse pallid mark.. Male with a very broad excision 
of the last ventral segment. 
Readily distinguished from D. pallipes, and from an undescribed Brazilian species, 
by the much broader head. Five examples.

Latior, fortiter punctatus, fuscus ; antennis, palpis, pedibus elytrorumque apice pallide testaceis.
