tured ; clothed with grey pile ; the dorsal tubercles and a stripe 
from each to the hind margin black, or thinly clothed with 
brownish-black pile. Elytra each with three or four slightly ele- 
vated longitudinal ridges, disappearing at about half the length ; 
a row of granulations (accompanied by punctures) on each ridge, 
besides three or four other rows in the interstices; the sides 
near the base also densely granulate-punctate : the fine hoary- 
grey pile is in large patches near the base ; elsewhere it forms 
regular rows of small, distinct, oblong spots. Under-surface of 
the body clothed with dense silky yellowish- grey pile, longest 
on the pro- and mesosterna. Legs clothed with grey pile, 
leaving spots on the femora, the tips of the tibiae, and of the 
claw-joints of the tarsi black. Abdomen (in 5 ) with the second 
to the fourth ventral segments contracted in the middle ; apical 
segment very large, tumid near the apex, which latter is trun- 
cate-emarginate and densely hairy. 
Taken at Para. It resembles very much adspersus (Dej.), 
Thoms. Class, p. 337. It may be a local form of that species.

JEgomorphus moniliferus, White, Cat. Long. Col. in Brit. Mus. ii. p. 374, 
pi. 9. fig. 7 . 
This, as will be seen from the excellent figure and description 
above quoted, is a narrower and more depressed insect than 
obesus. The c? has all the three sterna covered with a dense 
brush of hairs, more erect and of a brown colour on the meta- 
sternum. The apical ventral segment in the $ is large, with a 
longitudinal impressed line ending in a fovea before the apex ; 
the latter is emarginate-truncate and densely hairy. 
Pound at Para and Santarem, on trunks of felled trees. 
Genus Myoxomorpha. 
White, Cat. Long. Col. in Brit. Mus. ii. p. 355. 
Body thick, convex, elongated. Head broad, muzzle short, 
somewhat narrowed from the eyes ; sides rounded, obtuse : eyes 
distant on the vertex, very large, especially the lower lobes, 
which advance considerably on the forehead. Antennte shorter 
than the body, simple, neither grooved nor fringed. Thorax 
with large and very acute lateral tubercles. Elytra convex, 
elongated, their surface without ridges, apices briefly truncated. 
Legs moderate, tarsi short, femora clavate ; the fore tarsi in the 
males simple, neither dilated nor fringed. Prosternum narrow, 
simple, with the acetabular sutures angularly gaping ; mesoster- 
num broad, quadrate, horizontal. Abdomen with the terminal 
ventral segment sinuate-truncate in the males.
