with deep lateral fovese ; posterior angulated impression deep, dorsal line 
wanting. Elytra with deep sutural stria, dorsal stria wanting, represented 
only by the small basal fovea. Length .7 mm.; .028 inch. 
Detroit, Michigan, one specimen; Messrs. Hubbard and 
Schwarz. This species resembles in specific characters cer- 
tain Trimium (e. &. parvulum, convexulum), but is easily 
recognized by the less convex body, the more broadly mar- 
gined abdomen, and smaller antennal club. 
32. Euplectus cavicollis, n. sp.—Elongate, red-brown, finely 
pubescent. Head with a deep curved impression, ending behind in fovee ; 
front prominent, occiput moderately convex, not very shining. Prothorax 
more dilated on the sides than usual, with three very large posterior foveze, 
not connected by a transverse line; dorsal line very fine, abbreviated in 
front. Elytra with sutural stria deep, basal fovese small, dorsal strie want- 
ing. Length 1.2 mm.; .05 inch. 
Tampa, May ; one specimen. Very distinct from the other 
species in my collection by the large, separate foves of the 
prothorax. 
33. Acylophorus densus, n. sp.—Black, shining; head. and pro- 
thorax glabrous, of the same form and sculpture as in the other species. 
Elytra densely, not very finely punctured, sub-opaque, clothed with fine, 
dark pubescence. Abdomen slightly iridescent, pubescent, punctures be- 
coming more sparse behind ; ventral segments strongly iridescent. Legs (in- 
cluding front coxe) reddish-brown. Antenne piceous, black at base, 
joints 3-7 longer than wide, though not entirely equal either in length or 
breadth ; 3d joint a little shorter than the 2d. Length 5.5 mm.; .21 inch. 
Enterprise, May; one specimen. Larger than what I con- 
sider as A. pronus, equal to A. pratensis, but easily known 
by the punctures of the elytra more dense than in elther. 
34. Acylophorus flavipes, n. sp.—Shining black above, piceous 
beneath; head and prothorax as usual. Elytra coarsely and not densely 
punctured, sparsely pubescent. Abdomen hairy, strongly, not densely 
punctured. Legs (including front cox®) testaceous. Antenne not longer 
than the head and prothorax, piceous-black, base of 1st joint nearly testa- 
ceous ; joints 3-10 equal in length, gradually increasing in thickness, and 
closely approximated, outer ones transverse ; 2d joint fully as long asthe 
3d and 4th united. Length 4.5 mm.; .18 inch. 
Capron, May; one specimen. Smaller and more slender 
than A. pronus, with which it agrees in sculpture, but differs 
in the antenne and color of the legs. | 
The species of this genus resemble each other very closely,
