been obtained which show that E. colossus Lec. is a distinct species, and that 
the former belongs to the section of the latter. 
Bovsocerus Fossatus, § Bright pale ferruginous; clipeus prominent, con- 
fluently punctured, its dise concave at the end by the elevation of the margin, 
sides parallel, anterior margin with three teeth, one medial, bounded by an ob- 
tuse emargination which forms the lateral teeth at the anterior angles; anterior 
canthus of the eye prominent. Pronotum with two horns above directed late- 
rally, and slightly forwards, their posterior margin curving ina sharply defined 
semicircle, and forming an additional obtuse tooth on each side, which bounds a 
deep fossa anterior to it. Surface confluently punctured, particularly in the 
depressed portions, the prominent part above and posteriorly being smooth and 
shining. Lateral margin finely crenulate, with a slight emargination over 
the anterior angles; dorsal line distinctly impressed. Scutel sparsely pune- 
tured. Elytra paler posteriorly, and finely striate, the striae with fine punctures. 
Inferior parts of the body paler than above; clypeus, mandibles, maxille and 
serrations of the anterior feet margined with black. Length 83 lines.

B. tarorti. I propose to give this name to Bolbocerus ferrugineus|| Laporte, 
An. Art. Col. 2, 104, Westwood, Lin. Trans. vol. 21, p. 21. It is an East In- 
dian species, and not the true American Scarab. ferrugineus of Beauvois, 1805, 
Ins. 90, tab. 20, fig. 3. Scarab. ferrugineus Oliv. 1789, Ins. 1, 9, 3, p. 184, tab. 
23, fig. 202, belongs to a different genus. 
B. vestvupi. This name is proposed for Bolhocerus furcicollist Westwood, 
an East Indian species, confounded with the North American B. furcicollis Lap., 
itself a synonym of B. ferrugineus Beauv., and B. lecontet| Dej. Cat., as Dr. 
Le Conte has informed me. 
Greotrures opacus Hald. Purple black with scarcely any lustre. Head 
scabrous, except a small spot on the vertex, with scattered punctures; clypeus 
regularly rounded, front with three straight radiating lines starting from one 
impression, the posterior one short and medial, the anterior ones running to the 
margin, and enclosing a small scentral tubercle in the angle which they form; 
pronotum with irregularly scattered impressed punctures, less sparse in the 
dorsal line, which is slightly impressed posteriorly ; punctures becoming less 
sparse toward the lateral margins, where they are subconfluent; lateral fovea 
present, scutel punctate. Elytra smooth, scarcely striate, but marked by 16 
somewhat irregular rows of fine punctures. Pygidium scabrous, 8 lines long. 
Western Texas. Distinguished from G. blackhurnii Fabr. by the want of 
lustre, and the stria which connect the elytral punctures being evanescent, and 
in some parts wanting. 
Enopiium quaprinotatum flald Rufous, with four elytral spots arranged 
in a square ; surface scabrous, hirsute with black hairs. Head and prothorax 
rufous above and below. Front with a transverse impression between the 
anterior angle of the eyes; palpi, antenna, a spot on the vertex, feet, pectus and 
abdomen shining black. Prothorax longer than wide, the sides convex, project- 
ing most behind the middle; an evanescent black spot in front of the scutel. 
Elytra each with two conspicuous round black spots, one a little anterior to the 
middle, the other more than midway between the former and the apex. The 
size of the spots exceeds one third the width of the elytron. 3 lines long. 
Texas. Bears some resemblance to E. 4-punctatum Say; but that species 
has a black head and prothorax. As in that species the antenne are 10-arti- 
culate.
