THYSANOCNEMIS. 207 
subparallel in their basal third, punctate-striate, the strize shallow and the punctures rounded, the inter- 
stices almost flat and rugulose. Femora unarmed. 
Length 14, breadth 9 millim. (¢.) 
Hab. Panama, Tolé (Champion). 
One specimen. Distinguishable by its small size and narrow form, the elytra with- 
out markings and with the usual sete scarcely distinguishable from the pubescence. 
§ 2. Seriate punctures of the elytra oblong. 
8. Thysanocnemis zonatus, sp.n. (Tab. XII. figg. 2,2, 2.) 
Subovate, rufo-piceous or ferruginous, the elytra with a transverse mark on the disc below the base and two 
narrow angulated fascie (one at the middle and the other towards the apex) piceous, the under surface 
in great part black, the fifth ventral segment excepted, the antenne and legs rufo-testaceous ; thickly 
clothed with yellowish-grey pubeseence, that on the elytral markings sparse and infuscate, the suture 
with two blackish spots, the vestiture of the scutellum and under surface whitish, the elytral interstices 
each with an interrupted row of short, semierect, pallid setee extending from the base to the apex. 
Rostrum curved, moderately stout, about as long as the head and prothorax, closely seriate-punctate, 
carinate down the middle and faintly so at the sides, the antenne inserted near the tip; eyes very 
narrowly separated. Prothorax transverse, rounded at the sides, narrowed in front, closely, rather 
coarsely punctate, with a minute interstitial punctuation and indications of a smooth, raised, median line. 
Elytra subparallel towards the base, punctate-striate, the punctures oblong in shape and rather coarse, 
the interstices feebly convex and rugulose. Femora unarmed. 
Length 21-23, breadth 13-1 millim. (<¢.) 
Hab. Guatemaua, Cerro Zunil, Zapote (Champion). 
Two specimens. The markings are perhaps wholly due to the colour and 
arrangement of the pubescence, which is sufficiently dense to hide the greater 
part of the surface; the two fascize on each elytron are connected at the suture by a 
blackish spot. 
9. Thysanocnemis levirostris, sp.n. (Tab. XII. figg. 3, 3a, 2.) 
Subovate, ferruginous, the elytra with a transverse mark on the disc below the base and two narrow, 
angulated fasciz (one a little before the middle, extending forward along the suture, and the other 
towards the apex) apparently darker, the meso- and metasternum blackish, the rostrum, antenne, and 
legs testaceous ; thickly clothed with fine yellowish-grey pubescence, except on the elytral markings, 
whieh are almost bare, that on the seutellum and under surface whitish, the suture whitish, with two 
dark spots, the elytral interstices each with a row of semierect pallid sets extending from the base to 
the apex. Rostrum moderately stout, curved, as long as the head and prothorax, smooth and shining, 
shallowly suleate at the sides, the antenne inserted slightly before the middle; eyes very narrowly 
separated. Prothorax transverse, rounded at the sides, narrowed in front, closely, rather coarsely 
punctate, with a minute interstitial punctuation, the larger punctures absent along a narrow space down 
the middle of the disc. Elytra narrowing almost from the base, punctate-striate, the punctures oblong 
in shape and rather coarse, the interstices feebly convex and rugulose. Femora unarmed. 
Length 22, breadth 13 millim. (9.) 
Hab. Panama, Bugaba (Champion). 
One specimen. Very similar to the Guatemalan 7. zonatus (the male only of
