262 HETEROMERA. 
subcaudate, the humeri distinct, striate on the disc, with nine rows of very coarse rounded impressions ; 
epipleure rather broadly extending to the apex; prosternum horizontal, rather broad, its anterior face 
declivous, the apex acuminately produced ; mesosternum moderately deeply excavate ; metasternum short, 
longitudinally raised and convex in the centre between the middle coxe ; intercoxal process long, sub- 
parallel, comparatively not very broad (narrower than in the allied genera), narrowly margined, rounded in 
front ; tarsi long and stout, thickly clothed with hair beneath, laterally compressed, similar in both seXeS, 
the penultimate joints of the two front pairs strongly produced at their outer apices (these joints thus 
appearing bilobed), the first joint of the posterior pair long, the length of the two following Joints united, 
and at least three fourths of the length of the apical one; tibie very little curved, the posterior pair 
almost straight in both sexes, the inner apices slightly thickened in the male ; body apterous. | 
This genus includes a single species from Guatemala. Saziches in its gibbous elytra 
with rows of very coarse rounded impressions approaches Spherotus, Oxidates, and 
Isaminas ; it will be readily known from these genera by the long first joint of the 
posterior tarsi, the bilobed penultimate joints of the anterior and middle tarsi, the 
slender antennz, the large scutellum, the longer and narrower intercoxal process, &c.; 
and also from the two first named by the straighter tibie. 
The sexual organs in Saziches differ considerably from those of the preceding 
genera I have yet examined, though formed in both sexes almost exactly as in Hege- 
mona :—in the male the sheath of the cedeagus at about the middle is abruptly 
curved upwards, the apica] portion somewhat produced and subhorizontal, and the apex 
itself truncate, the intromittent organ being protruded from beneath but far from the 
apex; the sheath is protruded from the centre of what appears to be a completely 
hidden sixth segment, the latter when extended is found to consist of two long and 
broad valvular pieces which are corneous on their external sides, and above and below 
within densely clothed with matted fulvous spongy hair; in the female the ovipositor 
is formed of two broad vertical plates placed close together and acuminate at the apex 
and very similar to that obtaining in the same sex of Acropteron. In the male of 
Lsaminas the sheath is simply and gradually curved and narrowing to the apex, and 
of the ordinary character; the female of the same genus, and also of Ovwidates (at 
least of O. planicollis), has the usual horizontal flattened process with a short style 
on each side near the apex. We give a figure (Tab. XI. fig. 22 c) of the cedeagus 
of the male of S. swbcaudatus, viewed from beneath. 
1. Saziches subcaudatus. (Tab. XI. figg. 22,3; 22a, labium; 22 0, maxilla 
and maxillary palpus; 22 c, cedeagus.) 
Black, slightly shining. Head very minutely, sparingly, and almost imperceptibly punctured, the intraocular 
space broadly and shallowly impressed in the middle; prothorax transverse, widest in the middle, the 
sides slightly rounded, scarcely narrower at the apex than at the base, the hind angles subrectangular, 
the anterior angles rounded but not broadly so, the disc sometimes with a rounded fovea on each side 
before the middle, shallowly transversely impressed before the base, and with indications of a fine shallow 
obsolete central groove, smooth, almost impunctate; scutellum shining, usually transversely impressed 
behind ; elytra a little wider than the prothorax at the base, rapidly widening to the middle, rounded at 
the sides, strongly gibbous and raised greatly above the level of the prothorax (more so than in the allied 
genera), the apices produced, slightly divergent, and swollen, with rows of moderately deep coarse rounded
