this species, Nandarivatu, Sept. 6, 1938, Zim- 
merman. 
Differs from S. leveri (Bryant) in having 
the pro thorax narrower than the elytra, and 
more deeply and less closely punctured, the 
elytron a little more heavily punctured, and 
the dorsum more bronzy and more feebly 
pubescent. 
epinodostoma Gressitt, new genus 
Head deep, strongly raised on occiput, with 
a deep groove bordering upper half of eye; 
antenna distinctly thickened in distal half; 
prothorax feebly margined at side, slightly 
narrower than elytra, nearly as long as broad; 
elytra parallel, rounded apically, regularly 
seriate-punctate with one or two extra scutel- 
lar rows; middle and hind tibiae emarginate 
preapically on outer sides; tarsal claws bifid 
or toothed. Type: Epinodostoma alocasiae Gres- 
sitt, n. sp. 
This genus differs from Nodostoma in being 
more slender, in having a deep groove above 
the eye, and in having the prothorax hardly 
margined laterally. Heretofore, the tarsal claw 
character — bifid (branched) or appendiculate 
(toothed basally)— has been considered of 
tribal value in this subfamily. However, 
though the following two species seem to 
differ on this point, they are otherwise ex- 
tremely closely related. This fact, and other 
problems encountered in this study, indicate 
that this character has received undue impor- 
tance, or that other generic characters have 
been overlooked. 
54. Epinodostoma alocasiae 
Gressitt, n. sp. 
Fig. 21 
Shiny black with a purplish bronzy tinge, 
particularly on elytron; basal half of antenna, 
and much of tibiae and tarsi reddish. Glabrous 
on elytron, with very fine subrecumbent hairs 
on pronotum, and with sparse suberect hairs 
on ventral surfaces. 
Head three-fourths as broad as prothorax, 
deeper than wide, with moderately strong 
punctures, and a deep groove bordering upper 
half of eye; occiput strongly raised above. 
Antenna three-fifths as long as body, mod- 
erately stout except for third to sixth segments 
which are slender; scape a little longer than 
second; third subequal to scape, fifth, and 
sixth; fourth slightly longer; seventh to last 
each a little longer than fourth. Prothorax 
nearly seven-eighths as broad as long, more 
than seven-eighths as broad as elytra, rounded 
at side, slightly narrower at apex than at base, 
broadest one-third from base, strongly con- 
vex; anterior portion strongly raised, and also 
strongly convex in dorsal outline of anterior 
margin; lateral margin barely perceptible; 
disc deeply and subregularly punctured, with 
roughly 15 punctures along an approximate 
median line. Scutellum slightly longer than 
broad, narrowed and subrounded apically. 
Elytron two and one-fourth times as long as 
prothorax, subparallel-sided in slightly more
