368 RHYNCHOPHORA. 
slightly rounded in front, carina deeply concave, well separated from base. Scutellum nearly semi- 
circular. Elytra subcylindrical, elongate, strongly striate-punctate. Pygidium as long as broad, rather 
strongly narrowed, rounded apicad. Tibie (except tip) and base of femora rufous; first tarsal segment 
about half the length of the tibie, mid tibia with short spur at apex; claw-segment of fore tarsus 
shorter than first segment. 
Length 2 millim.

14. Ormiscus pusillus. 
Toxotropis pusillus, Leconte, Proc. Amer. Philos, Soc. xv. p. 398 (1876) *. 
¢ 2. Black beneath, pubescent-grey ; brown above, variegated with brown and grey. Head and rostrum 
uniformly grey; frons of 9 half as wide as the rostrum, of ¢ less than half. Antenna rufous, club 
brown. Anterior lobe of eye much narrower than posterior. Prothorax about as long as broad, much 
less narrowed from the carina forward than usual in this genus, the sides remaining almost parallel to 
near the apex; a transverse spot close to apex and another band-like spot behind it brown, four large 
brown spots a little distance from carina, the lateral one nearly extending to the apex and including a 
grey dot, these spots doubtless variable individually ; carina well separated from base, nearer the base 
in middle than at sides, not projecting laterad. Scutellum nearly semicircular. Elytra cylindrical, 
elongate, not pustulate, evenly punctate-striate, with the basal callosity just vestigial; grey spots 
merged together into irregular transverse bands, about seven in number, first at base. Pygidium grey. 
Legs brown, basal two-thirds of tibia and base of first tarsal segment rufous ; first tarsal segment a little 
longer than claw-segment ; mid tibia of gd obtusely dilated at apex, hind tibia with truncate mucro.

One pair. 
15. Ormiscus minor, sp.n. (Tab. XIV. fig. 4.) 
2. Similar to O. pusillus, more coppery-brown above, grey markings smaller. Eye shorter, more rounded, 
more prominent. Antenna black, rufescent at base, short; eighth segment hardly longer than broad. 
Prothorax a little narrower, with the sides slightly more oblique ; a mesial vitta and some lateral spots 
luteous-grey; carina nearer the base, especially in middle, than in O. pusillus, laterally more oblique, 
being almost evenly concave from side to side. Hlytra shorter, apically more strongly declivous, luteous- 
grey pubescence much more restricted, forming more or less interrupted transverse bands; subbasal band 
broad, connected with basal margin of elytra by a streak in fifth interstice and another upon suture. 
Legs brown-black, tibie rufescent. 
Length 13-12 millim,

A short series. 
16. Ormiscus nanus, sp. n. (Tab. XIV. fig. 5.) 
g. Black, shining, sparsely pubescent brown and grey, the hairs longer than usual; the grey hairs rather 
more numerous on head and rostrum, on sides, at base and in middle of apex of pronotum, on and behind 
scutellum, in a transverse subbasal band on elytra and behind middle of the latter; pygidium covered 
with short grey pubescence. 
Frons half the width of the rostrum. Mouth-parts luteous, except tip of mandibles. Antenna slightly
