206 RHYNCHOPHORA. 
widening forwards, seriate-punctate at the sides, in the 9 smoother, the antenne inserted towards the 
tip; eyes subapproximate. Prothorax transverse, rounded at the sides, narrowed in front, densely 
punctate, with indications of an abbreviated, smooth, raised, median line. FElytra punctate-striate, the 
interstices feebly convex and densely, rugulosely punctulate. Femora unarmed; anterior tibie sinuate. 
Length 2-24, breadth 15-13 millim. (d @.) 
Hab. Guatemata, Tamahu in Vera Paz (Champion). 
One pair. Very like 7. suturalis, but with two black fascie on the apical half of 
the elytra, these being separated by an angulated line of the ground-colour, on which 
at the suture is an oblong patch of whitish pubescence; the squamiform whitish sete 
are absent from the apical portion of the second interstice; the eyes are almost 
approximate; and the femora are unarmed. From 7. versicolor its smaller size, the 
more finely punctured prothorax, and the different arrangement of the elytral markings 
sufficiently distinguish it. 
6. Thysanocnemis versicolor, sp.n. (Tab. XII. fig. 1, 2.) 
Subovate, rufo-piceous, variegated with black, the most conspicuous markings on the elytra being a broad, 
angulate, median fascia, which is sometimes interrupted near the suture, and an interrupted, sutural 
stripe extending from about the middle to the apex, the under surface in great part black, the antenne 
and tarsi ferruginous; clothed with yellowish-grey pubescence, except on the dark markings, where the 
vestiture is blackish, the scutellum and a more or less distinct oblong patch on the suture towards 
the apex with whitish pubescence, the elytra also with short, scattered, whitish, squamiform sete ; the 
vestiture of the under surface whitish. Rostrum (¢) stout, curved, about as long as the prothorax, 
seriate-punctate, earinate down the middle and also at the sides, (Q)a little longer and smoother, the 
antenne inserted near the apex in the ¢ and at about one-third from the tip in the 2; eyes narrowly 
separated. Prothorax transverse, rounded at the sides, narrowed in front, closely, somewhat coarsely 
punctate, with a minute interstitial punctuation, and indications of a smooth, raised, median line. Elytra 
punctate-striate, the interstices feebly convex, and densely, rugulosely punctulate. Femora unarmed ; 
anterior tibize sinuate. 
Length 24-3}, breadth 12-1? millim. (¢ 2.) 
Hab. Mexico, Cordova (Hége); British Honpuras, Rio Hondo (Blancaneauz) ; 
GuaTeMALA, Pantaleon (Champion). 
Four specimens, varying a good deal in size and in the extent of the black macula- 
tion of the elytra, the median fascia sometimes reaching the suture, but the dark 
markings never extending to the tip, as in 7. ornatus. The oblong patch of white 
pubescence on the suture towards the apex is conspicuous, the first elytral interstice 
being velvety-black before and beyond this. The whitish squamiform sete on the 
elytra are coarser and more numerous than in 7. obscurus and T. bicinetus. 
7. Thysanocnemis pusillus, sp. n. 
Subovate, narrow, ferruginous, the legs testaceous ; somewhat sparsely pubescent, the pubescence of the upper 
surface yellowish-grey, slightly intermixed with whitish, that of the under surface white, the usual short 
interstitial sete scarcely distinguishable. Rostrum moderately stout, about as long as the prothorax, 
seriate-punctate and feebly tricarinate, the antenne inserted towards the tip, the eyes large and very 
narrowly separated. Prothorax transverse, moderately rounded at the sides, a little more narrowed in 
front than at the base, closely, rather coarsely punctate, with indications of a raised median line. Elytra
