[LeConte, 
ZAPLOUS, n. g. (CERAMBYCIDÆ, subf. LAMTID.E.) 
Body small, not very robust, clothed with prostrate, short pubescence. 
Head rather short, not channeled, support of labrum coriaceous, eyes rather 
coarsely granulated, deeply emarginate, upper part much smaller than the 
lower. Antenne a little shorter than the body, 11 jointed, with very few 
flying hairs on the lower edge; 1st joint long, slender, slightly clavate 
(very much asin Leptostylus, Liopus &c.); 2d joint cylindrical, nearlv one 
third as long as the Ist 3d and 4th elongate, together equal to the remaining 
ones united, which gradually diminish in length, but not in thickness. 
Prothorax wider than long, not tuberculate, sides rounded, sometimes in- 
distinctly angulated ; front coxal cavities widely angulated. Elytra wider 
than the prothorax, parallel, humeri well rounded. tips rounded, not trun- 
cate. Front cox® prominent, narrowly separated, middle coxæ more widely 
separated, cavities open externally. Legs short, thighs stout, but not cla- 
vate; front tibie with inner groove feeble; middle tibie with a slight 
but distinct tubercle on outer margin. Tarsi short, not slender, 1st joint 
scarcely longer than 2d ; last joint long, claws divaricate. 
The small insect which indicates this genus belongs to the 
tribe Pogonocherini (Lec. Class. Col. N. Am. 340), but does 
not fit well into any of the groups thus far known in our 
fauna.* 
105 Zaplous Hubbardi, n. sp.—Brown, clothed with short, pros- 
trate yellowish-gray pubescence, somewhat mottled by unequal distribu- 
tion. Prothorax very densely, rather finely punctured. Elytra more 
strongly and less densely punctured. Antenne annulated with black, 
finely punctulate and pubescent, without mixture of large punctures. 
ength 3.3-5 mm. ; .13-.29 inch. 
Enterprise; frequently beaten from old vines, in May. 
104. Donacia rugosa, n. sp.—Coppery-bronze, not shining, rugose, 
rather robust, sub-depressed. Head channeled in front, line deeper behind, 
and ceasing between the eyes ; eyes convex, prominent, orbits wide. Pro- 
thorax quadrate, a little wider in front, where the angles are well-marked, 
sides not sinuate ; surface densely rugose and punctured, dorsal line widely 
impressed but vague, feebly, transversely impressed near the base. Elytra 
obliquely narrowed towards the tips, which are truncate ; discoidal impres- 
sions vague, the 1st small, near the scutellum ; the 2d large, in front of the 
middle ; the 3d small, near the suture, and behind the middle ; striæ com- 
posed of elongate punctures, interspaces densely, transversely rugose. Be- 
neath dark plumbeous, with fine, pruinose pubescence. Hind thighs ( 9) 
not toothed, antenns slender, three-fourths as long as the body, blackish. 
Length 9.2.mm.; .37 inch. . 
Enterprise; May, one specimen. Allied to D. subtilis, but
