Biology of Eleodes Suturalis

with numerous closely and irregularly placed punctures, which become denser and 
rather more strongly muricate towards margin; apical declivity somewhat more 
strongly sulcate and scabrous; indexed sides not convex, obsoletely sulcate, irregularly 
and muricately punctured. 
E pi pleura moderately narrow, uncinately dilated beneath the humeri, and gradually 
narrowing to apex; surface usually more or less obsoletely punctate. 
Sterna and para pleura more or less obsoletely or strongly punctate and rugulose. 
Abdomen finely and more or less sparsely, obsoletely punctate and rugulose. 
Legs moderate. Anterior femora armed in the sexes; protibial spurs and protarsi 
nearly alike in the sexes, the spins are quite strongly divergent. The first joint of 
the protarsi is more or less thickened and slightly produced at apex beneath, bearing 
a tuft of yellowish pubescence. 
Male. —About twice as long as wide. Antennae scarcely reaching to the basal margin 
of the prothorax. Elytra moderately, suddenly, and obliquely declivous posteriorly; 
apex slightly acuminate. Abdomen slightly oblique, moderately convex, broadly 
impressed on the first two segments. Anterior femora with an acute tooth about one- 
fourth distance from the apex; posterior spur of the protibiae apparently a little longer 
and slightly stouter than the anterior, frequently they appear to be quite equal in 
length, both are rather stout and acute; first joint of the protarsi with the produced 
tip beneath rather thick and bearing a small obtuse tuft of modified spinules, groove 
not evident. 
Female. —Less than twice as long as wide. Antennae reaching to about the posterior 
fifth of the prothorax. Elytra quite suddenly obliquely or vertically declivous poste¬ 
riorly. Apex obtuse. Abdomen horizontal, evenly and strongly convex. Anterior 
femora with a small obtuse tooth, sometimes scarcely more than sinuate in outer fourth; 
posterior spur of the protibiae a 
little longer and stouter than the 
anterior, both are acute, moder¬ 
ately thick, and gradually nar¬ 
rowed from the base; first joint of 
the protarsi slightly and trans¬ 
versely produced at tip beneath, 
bearing a transverse tuft of spi¬ 
nules, which is more or less acute, 
groove more or less obsolete. 
The male genital characters do 
not apparently show any racial 
differentiation. 
Male. —Edeagophore of the 
usual oblong-ovate form. 
Basale oblong, scarcely arched, 
and may be sparsely punctate 
laterally at apex. 
Apicale rather broadly triangu¬ 
lar, moderately depressed, sur¬ 
face more strongly convex api- 
cally, with a median membranous 
groove in apical half; sides rather 
straight to slightly arcuate; apex 
scarcely produced and more or 
less deflexed, subacute; base 
broadly lobed at middle, and sin¬ 
uate laterally. 
Sternite transverse. Each lobe 
with the external border more or 
less evenly arcuate, and the inter¬ 
nal short and straight to feebly arcuate, with apex rounded; surface densely punctate 
and setose in apical two-thirds, setae quite long and not extending upon the membrane 
across the sinus; the latter nearly closed by the same. The lobes internally at base 
and cephalad to the sinus are rendered semicircularly sinuate by an interlobar trans¬ 
versely oval membranous area, the membrane of which is frequently transversely 
rugose.
