sides: antepectus somewhat regularly punctured, punctures elevated: scutel 

 black : elytra punctate-striate, interstitial lines elevated ; an irregular undulating 

 silvery vitta upon the lateral submargins, extending from humeral angle to apex, 

 interrupted in the middle, and merging into scattered variegations behind the 

 sutural middle : legs with cupreous reflections, finely pubescent ; a silvery spot 

 immediately in front of posterior coxa? : venter punctulate, silvery. A very dis- 

 tinct and beautiful insect, which I doubtingly refer to the genus cited. A very 

 rare species, two individuals only having occurred. 



BARIDIUS, Sch. 



B. pubescens. Entirely covered with dense, fulvous pubescence. 



4 lines long to tip of rostrum. Virginia. 



Densely yellowish pubescent : head, rostrum and eyes piceous-black, rostrum 

 slightly pubescent at base ; antenna? black, club piceous : thorax densely pubes- 

 cent, pile running transversely each side from the middle, middle slightly 

 elevated: legs and feet pubescent: elytra striate punctate, punctures not visible 

 through the pubescence : beneath densely pubescent. 



A very distinct species, and may be easily recognized by the uniform long 

 yellowish pubescence with which the whole body is invested. Rubbed specimens 

 appear brownish, the pubescence being very deciduous. 



ACANTHODERES, Serv. 



A. Morrisi. Whole body covered with bluish-cinereous pubescence ; 5 spinous 

 tubercles upon the thorax, exclusive of the lateral ones; elytra each with a sub- 

 lunulate macula behind the middle. 11 lines long; 5 broad. Baltimore. 



Cinereous pubescent : head brownish, punctured; labrum piceous, ciliate in 

 front with yellowish hairs ; frontal line entire, a longitudinal elevation each side 

 at base; antennae annulate with black, 1st joint thickened at extremity: thorax 

 anteriorly and posteriorly, sparsely and coarsely punctured, three spinous tuber- 

 cles on the middle placed laterally, external ones bipartite, lateral spines hardly 

 acute: scutel with two round dots of black pile, densely pubescent: elytra 

 roughly shagreened, slightly elevated each side, behind the scutel ; humeri pro- 

 minent, acute; 4 elevated striae containing black dots, lateral and sutural mar- 

 gins dotted black; also 4 black dots on each side, one near the lateral margin, 

 one behind the humerus, one immediately in front of the apex, and a large 

 somewhat lunate (anteriorly emarginate, and posteriorly trifurcate) spot, the 

 outside branch of which runs obliquely outwards, each spot surrounded with a 

 fulvous margin ; tips obliquely truncated, slightly divaricate : femora stroDgly 

 clavate, black at tip and reddish at base, tibia? annulate with black, tarsi black- 

 ish, pulvilli yellow; venter terminal segments almost without pubescence. 



1 take great pleasure in dedicating this beautiful insect to the Rev. John G 

 Morris, as a slight testimonial of my esteem for him as an eminent Entomologist, 

 and liberal patron of the natural sciences. 



DORCASCHEMA, Lee. 



D. Wildii. Ground color brown, entirely invested with dense cinereous pubes- 

 cence ; antenna? basal joints finely pointed with brown ; lateral yellowish vitta 

 extending from behind the eyes to apex of elytra. 10 lines long; (elytra 7;) 

 2J wide. Baltimore upon Morus. 



Densely cinereous pubescent: head ashy pubescent with a lateral yellowish 

 vitta, frontal line impressed ; mandibles and palpi piceous-black : antennas ter- 

 minal joints annulate with blackish, basal ones scabrous, finely pointed with 

 brown, pubescent: eyes dark brown : thorax lineate with yellow each side, and 

 together with the head very finely, transversely wrinkled, dorsal line obsolete 

 anteriorly: scutel cinereous pubescent ; elytra a little less densely pubescent, 

 beautifully marked with fine brown points, humeral angles prominent, base 

 coarsely and closely punctured, becoming less so posteriorly : legs densely 

 pubescent, finely and closely brown-punctured : venter ciliate at tip. 



It affordes me much pleasure in dedicating this fine insect to Mr. J. P. Wild,
