been obtained which show that E. colossu:5 Lee. is a distinct species,,and that 

 the former belongs to the section of the latter. 



BoLBocERUs FossATus, % Bright pals ferrusiinous ; clipeus pronninent, con- 

 fluently punctured, its disc 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. Fronotum with two horns above directed late- 

 rally, and slightly forwards, their posterior margin curving in a 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 

 depresseil portions, the prominent part above and posteriorly being smooth and 

 shining. Lateral margin finely rrenulate, with a slight emargination over 

 the anterior angles; dorsal line distinctly impressed. Scutel sparsely punc- 

 tured. Elytra paler posteriorly, and finely striate, the striae with fine punctures. 

 Inferior parts of the body paler than above; clypeus, mandibles, maxillae and 

 serrations of the anterior feet margined with black. Length 8g lines.

B. LAPORTii. I propose to give this name \.o Bolbocerns ferrugiiiensW Laporte, 

 An. Art. Col. 2, 104, VV'estwood, Lin. Trans, vol. 21, p. 21. It is an East In- 

 dian species, and not the true American Scarab, femigineus of Beauvois, 1805, 

 Ins. 90, tab. 20, fig. 3. Scarab, frrrvghie us Oliv. 1789, Ins. 1, 9, 3, p. 18-1, tab. 

 23, fig. 202, belongs to a different genus. 



B. VESTvuDii. This name is proposed for Bolhoeertcs fitrcicollis\ Westwood, 

 an East Indian species, confounded with the North American B, fitrcicollls Lap., 

 itself a synonym of B. fftrraginens Beauv., and B. lecontei^ Dej. Cat., as Dr. 

 Le Conte has informed me. 



Geotrupes opacus llald. 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 central tubercle in thf> 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 J6 

 somewhat irregular rows of fine punctures. Pygidium scabrous, 8 lines long. 



Western Texas. Distinguished from G. blaclhurnli Fabr. by the want of 

 lustre, and the striae, which connect the elytral punctures being evanescent, and 

 in some parts wanting. 



Enoplium QUADRiNorATTJM Ilahl Rufous, with fouT 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, antennre, a spot on th^^ 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. A-p/c net at ur/i ?>a.y; but that sppcies 

 has a black head and prothorax. As in that species the antennce are lO-arti- 

 culate.
