16 Mr. H. W. Bates on the Longicorn Coleoptera 
suture, connected with a lighter streak on the disk, and, lastly, 
a distinct arcuated yellowish line on each side near the apex ; 
the suture near the base and apex is also bordered with yellowish 
ashy. Body beneath hoary white, breast and base of abdomen 
on each side with dark oblique stripes: abdomen sometimes 
reddish. Legs reddish; apical halves of tibize and tarsi black ; 
basal joints of tarsi ashy. 
$ Terminal abdominal segment with dorsal and ventral plates 
rather deeply notched. 
? Ovipositor greatly elongated and exserted beyond its sheath, 
apical dorsal plate pointed, ventral deeply and narrowly cleft. 
This pretty species, which differs from T. figuratus by the 
more tapering shape of its elytra, and by the markings on the 
surface of the wing-cases, was met with at various places on the 
southern side of the Lower Amazons, and on the banks of the 
Tapajos, but never in abundance. 
3. Toronaeus perforator, n. sp. 
T. oblongus, convexiusculus, fuscus, nigro fulvo canoque variegatus : 
elytris apice cinereo marginatis et fasciatis ; foeminz stylo elonga- 
tissimo. Long. 23-53 lin. ¢ Q. 
Head velvety black, cheeks ashy, vertex with a short yellow 
line. Antenne slender, more than twice the length of the body 
in both sexes, reddish testaceous, all the joints except the first 
and second with a pale ring at their bases. Thorax very little 
broader than the head, the sides in the middle with a slight 
protuberance, surface dark brown, with blackish spots on the 
disk and fulvous spots on the sides, a curved ashy streak below 
the lateral protuberance. Scutellum black. Elytra oblong, not 
narrowed until near the apex, at which point they are suddenly 
narrowed to the tip, which is obliquely truncated; surface 
thickly punctured, except near the apex, dark purplish brown, 
sides with greyish marks, and disk spotted with black, some- 
times varied also with obscure greyish and fulvous streaks and 
spots, a more distinct but short oblique pale line existing, in all 
examples, on each elytron a little before the middle near the 
suture ; the apical margin, both sutural and external, has a neat 
ashy border, which, being joined to a preeapical fascia of the same 
hue, encloses a transverse blackish spot. Body beneath clothed 
with silky grey pile. Legs more or less reddish, with ashy and 
black rings. 
g Terminal abdominal segment with dorsal plate semicircu- 
larly notched at the tip, ventral with a shallower notch. 
2 Ovipositor greatly elongated, the sheath extending. more 
than two lines beyond the tips of the elytra; dorsal plate finely 
pointed, ventral cleft at the tip.
