culis ovatis, obliquis et postice elevatis ; thoracis tuberculis latera-

Head brown ; front naked, coriaceous, punctured, black ; eyes 
moderate, reaching little more than halfway down the forehead; 
vertex very convex. Antennae rather shorter than the body ( $ ), 
tapering to the apex, basal joint curved ; colour brown. Thorax 
twice as broad as long, a little narrowed behind the lateral tu- 
bercles, which are long and spiniform ; surface dull ashy brown, 
with a central transverse black line. Elytra massive, narrowed 
to the apex, convex, especially in the middle of the basal part on 
each side; shoulders prominent and oblique, with a conspicuous 
tubercle at their hinder angles ; colour ashy brown, paler near 
the middle, and covered with small, oblong, raised, scale-like 
tubercles, which are very crowded and strongly elevated at their 
posterior ends near the base, much scattered and very slightly 
elevated near the middle, and arranged in rows, simply as spots,

Genus Eudesmus, Serville. 
Serville, Ann. Soc. Ent. Fr. iv. (1835) p. 82. 
This well-marked genus resembles Oncideres in its cylindrical 
form of body. Its distinguishing character is derived from the 
bulbous ovate shape of the third antennal joint in the male. 
* The following new species have lately been received from entomological 
travellers in South America : — ^ 
Oncideres limpidus. Cylindricus, fusco-nitidus ; elytris fulvo-ochraceo 
irroratis. Caput ( S ) modice angustatum, fronte punctata, ochracea, 
vitta infraoculari nigra; tuberculis antenniferis intus prominulis, 
acutis. Antennae corpore longiores, nigrae nitidae; articulo basali 
distincte clavato, articulis tertio et quarto infra dense ciliatis. Thorax 
postice angustatus, tuberculis lateralibus modice productis, nigris ; 
supra ochraceo-brunneus, linea nigra transversa, ante medium fascia 
rufo-fulva. Elytra cylindrica, fusco-nitida maculis numerosissimis 
discretis tomentosis ochraceo-fulvis ; juxta basin tuberculis globosis 
paucis; deinde leviter granulata, humeris confertim tuberculatis. 
Corpus subtus fulvo-tomentosum. Pedes nigricantes, femoribus 
fulvo tomentosis. Long. 10 lin. <? . Hab. in Bahia Brasilije, a Dom. 
Reed lecto. 
Oncideres Bouchardii. Cylindricus, cano-griseus ; elytris nigro punc- 
tatis et maculis majoribus rotundatis fulvis sparsis. Caput latum, 
griseum, maris paulo angustius, tuberculis antenniferis intus vix pro- 
minulis. Antennae griseae ; articulo basali gradatim incrassato, nigro, 
maris valde rugoso. Thorax griseus, linea transversa nigra. Elytra 
convexa, vage punctata, cano-grisea, maculis rotundatis carneo-fulvis 
conspersa, punctis nigris ; prope basin tuberculis numerosis globosis. 
Corpus subtus pedesque cano tomentosa. Long. 10-11 lin. S $ . 
Hab. in Sta. Martha Novae Granatae, a Dom. Bouchard copiose missus.
