Proconus, n. gen.—Rostrum obconical, as long and, in front, as 
broad as the head, broadly impressed anteriorly ; its scrobes 
oblique. Antenne shortand stout; scape short, gradually thickened ; 
funiculus 5-articulate, longer than scape, two basal joints obconical, 
2nd larger than 3rd; club ovate, compact, its base not greatly 
exceeding the 5th joint in breadth. Head exserted, with a broad 
neck. Eyes small, oviform, distinctly facetted, not prominent. 
Prothovax considerably narrowed and constricted in front, broadly 
rounded behind the middle.. Scutellum distinct. Elytva elongate- 
oblong, base truncate, apices rounded. Legs stout ; femora in 
flated ; thie sub-triangular, with distinct hooks ; favs: rather 
short, 3rd joint deeply emarginated. 
Body rather broad, depressed, with a few longish hairs on the 
front of the thorax, and minute ones on the hind-body. Female 
incog. 
Should be located near Hetevopsis. 
This genus is constituted for Pentarthrum asperivostve, which, 
therefore, must stand as Proconus asperivostris. 
Eudontus,n.gen.--Rostvum rather elongate, a little arched, paral- 
lel, slightly dilated at the apex ; scvobes linear, extending from near 
the apex to the ‘lower part of the eyes. Antenne elongate, 
implanted near the apex; scafe long, slender, and some- 
what incrassated at the extremity ; fwmiculus 7-articulate, basal 
joint large, obconical, joints 2-7 decrease in length, the last 
broadest, quite transverse, 2nd longer than 3rd ; club large, ovate, 
obsoletely articulated. Mead globuliform, immersed, Eyes large, 
slightly prominent, distinctly facetted, rounded below, truncated 
inwardly. Pvothovax transversal, base and apex truncate, sides 
rounded.  Scutellwm distinct, triangular. Elytva oblong-oval, but 
slightly curved laterally. Legs robust, four anterior femora cla- 
vate, deeply notched at the extremity, so as to be sharply angu- 
lated beyond the middle, the posterior somewhat similarly 
formed, but quite dentate below ; tie stout, flexuous, mucro- 
nated but not visibly hooked at the extremity ;, ¢avsi rather 
broad, penultimate joint expanded and bilobed. Body rather 
broad, but little convex, pubescent. 
Intermediate between Pogonorlinus and Arecophaga, the rostrum 
like that of the latter, but not ciliated as in the former. 
1434. Ludontus punctithorax, n. sp.—Sub-oblong, slightly 
convex, not very glossy, bearing fine griseous hairs ; fusco-cas- 
taneous, legs and antennz more or less rufescent. | 
Rostrum not twice the length of the thorax, cylindrical, almost 
bi-sulcate. Pvothovax broader than long, nearly flat above, 
rounded laterally, narrower in front than behind ; its punctation 
neither close nor deep, the intervals between the punctures 
densely and minutely sculptured. Elytva broader and twice as 
long as the thorax, slightly incurved at the base, the sides but 
little rounded, apices not expanded, striate-punctate, interstices 
nearly plane, closely but minutely, punctated, not elevated nor
