59. Proctorus armatus Lec. Rhynch. 212. 
Several specimens of this curious insect were found at 
Marquette, and among them are o'o' in which the two pro- 
cesses of the apical edge of the last ventral segment are very 
short, and scarcely apparent, though the anterior tubercle or 
spine and the large excavation are as well developed as in 
the other specimens. 
60. Proctorus decipiens Lec. ibid. 213, (Hncalus.) 
3 Apical part of last ventral segment suddenly transversely depressed, 
with a short erect spine each side. 
Marquette. The differences in the rostrum upon which I 
separated Hncalus from Proctorus, are only sexual; and the 
peculiar ventral armature of the ~ shows that they consti- 
tute but one genus. 
61. Orchestes canus Horn,* n. sp. Black, sparsely clothed with 
grayish pubescence. Antenne -testaceous, funicle six-jointed. Thorax 
broader than long, apex one-third narrower than base, sides arcuate, disc 
coarsely punctured. Elytra oval, gradually narrowed posteriorly, disc con- 
vex, deeply and rather broadly striate, strize with coarse, deep and closely 
placed punctures, intervals irregularly biseriately punctured, the punc- 
tures bearing short grayish hairs. Body beneath and legs black. Length 
3mm.; .12 inch. 
The posterior femora are strongly thickened. This species cannot be con- 
founded with any other than pallicornis, from which the deeply striate 
elytra, and very evident grayish pubescence will distinguish it. 
Specimens are before me from Isle Royale and Escanaba, 
Michigan, and from San Juan, Colorado. 
62. Orchestes minutus Horn, n. sp. Black, sparsely clothed with 
grayish pubescence. Antenne piceous, scape and first joint of funicle paler, 
the funicle 6-jointed. Thorax broader than long, apex scarcely narrower 
than base, sides arcuate, surface coarsely punctured. Elytra oval, broadest 
at middle, dise slightly flattened, deeply striate, strive with indistinct dis- 
tant punctures, intervals wrinkled, irregularly, finely, biseriately punctu- 
late. Body beneath and legs black. Posterior femora feebly thickened. 
Length 2 mm.; .08 inch. 
This species resembles rufipes, but is somewhat smaller, dise of elytra 
flatter and with entirely black legs, and with the thorax much more arcuate 
at middle. , 
Four specimens, California, from Mr. James Behrens, col- 
lected probably near Sauzalito. 
* Dr. Horn has kindly prepared the table of this genus and the descriptions of 
the two new species.
