24 ' rjune, 
as in Oregostoma ; filiform, tliickening and the joints becoming subserrated towards 
the apex. Elytra normal, sides nearly vertically deflexed, the upper limits of the 
deflexed portion carinated, apex obliquely truncated.

(Bhinotragus, id). 
Argyrodines, n. g. 
Snblinear, moderately elongated. Muzzle broad, elongated, oblique, front 
broad, plane. Eyes finely facetted. External maxillary lobe and terminal joint of 
the palpi greatly elongated. Antennae filiform, bristly, as long as the body ( ? ), 
basal joint clavate, 3rd greatly elongated, swollen at the apex, 4th about one-third 
the length of the third and three-fourths the length of the 5th. Thorax about 
two-thirds the length of the elytra, constricted in front and behind, the interme- 
diate portion forming a tumid, rounded mass on each side. Elytra plane, constricted 
in the middle, obtusely rounded at the apex. Legs short, bristly, hind pair 
longest, thighs clavate, tibise compressed, tarsi rather short, basal joints elongate- 
triangular. Mesosternum rather broad, plane. 
A. pulchella, n. sp. 4 lines. ? . Deep glossy black : elytra each with three 
oblique impunctate streaks of silvery -white ; two (narrower) before, and one (broader) 
behind the middle. Head thickly punctured. Thorax with the anterior constricted 
portion and middle of tumid part on each side impunctate, the posterior constricted 
portion sharply striated transversely, rest of surface closely foveated, with the 
interstices forming a reticulated pattern. Elytra closely punctured, except the 
white streaks and a space on the basal side of the streak. Sides of mesosternum 
with a patch of white hairs. Hind tarsi clothed with similar hairs. 
Ega. The genus is without doubt closely allied to Cosmisoma. 
Chlorethe, n. g. 
Facies of Clirysoprasis. Body clothed with short bristles. Muzzle very short ; 
eyes coarsely facetted : maxillse with the exterior lobe short and broad. Antennae a 
little longer than the body (<?), shorter than the body ( ?) ; third to fifth joints 
thickened, and, in the ^ , clothed with longer bristles, most numerous and dense 
on the fifth. Thorax short, sides rounded, unarmed. Legs shortish, as in 
Orthostoma, thighs simple, tibiaj compressed, with two conspicuous spurs at their 
apices ; tarsi short, much more slender than in Orthostoma, basal joint in the hind 
pair sub-linear. 
C. Ingcc, n. sp. SJ — 4^ lines. <? ? . Head, thorax, basal joint of the antennae, 
and breast, brassy-green ; rest of antennge black ; legs bronzed-black, elytra silky- 
green ; abdomen red. Head and thorax very closely punctured, interstices 
reticulated. Elytra finely punctured, with a bristle arising from each puncture. 
Presternum transversely rugose ; mesosternum coarsely rugose-punctate ; meta- 
sternum with shallow, scattered punctures, glossy. 
Ega ; on felled Inga trees. The genus will range next to 
OrtJwstoma. 
MiCROSPILOMA, n. g. 
Body rather short, sub-cylindrical. Muzzle elongated, palpi truncated. Eyes 
rather coarsely facetted, slightly prominent. Antenna short, third and fifth joints
