194 RHYNCHOPHORA. 
narrow in front of the anterior coxee; legs subequal in length, the femora unarmed, all the tibie 
unguiculate, the tarsal claws with a long tooth ; the other characters as in Anthonomus. 
The single species referred to this genus cannot very well be included in Anthonomus. 
Following Dietz’s arrangement, it should come near Tachypterus *. 
1. Dietzia bifasciata, sp.n. (Tab. XI. figg. 12, 12a, 4, 3.) 
Subovate, rather dull, ferruginous, the head, the prothorax (a transverse space on the disc in front excepted), 
a transverse median fascia on the elytra and a sinuous narrower one before the apex, and the meta- 
sternum, infuscate or piceous; finely pubescent, the elytral interstices each with a row of short decumbent 
squamiform sete, and the prothorax with squamiform pubescence on the disc at the base, the vestiture 
ochreous on the light-coloured portions of the surface and darker elsewhere, that of the scutellum and 
under surface paler. Head closely punctured; rostrum rather stout, feebly curved, shining, seriate- 
punctate at the sides, smooth along the middle, the antenne inserted at about one-third from the apex, 
joint 1 of the funiculus stout, twice as long as 2, 3-7 transverse and closely articulated. Prothorax 
broader than long, moderately rounded at the sides, a little more narrowed in front than at the base, the 
latter very feebly sinuate, the surface densely, rugulosely punctate. Elytra one-half wider than the pro- 
thorax, short, sinuate at the base, the sides parallel in front, the humeri rather prominent; punctate-striate, 
the interstices convex and punctulate. Legs rather short; femora deeply excised towards the apex 
beneath (so as to appear angularly dilated when viewed in a certain position); anterior tibie feebly 
sinuate within. 
Length 23, breadth 13 millim. (<¢.) 
Hab. Paxama, Bugaba (Champion). 
One specimen. Readily recognizable by the bifasciate, broad, subcordate elytra, the 
unarmed femora, the unguiculate posterior tibie, &c. The anterior legs are very little 
longer than the others. The claw at the apex of the hind tibie is extremely small 
and not easily seen. 
PSEUDANTHONOMUS. 
Pseudanthonomus, Dietz, Trans. Am. Ent. Soc. xviii. p. 248 (1891) (part.). 
To this genus are referred all the Central-American Anthonomids with a 6-jointed 
funiculus, long, lateral or descending scrobes, unidentate or simple femora, mucronate or 
unarmed posterior tibie, and toothed tarsal claws. Dietz attaches greater importance 
to the position of the scrobes than to the number of joints in the funiculus; but the 
first-mentioned character cannot be relied upon, the scrobes varying in position, as 
might be expected, according to the length, curvature, and thickness of the rostrum, 
and this is also the case in Anthonomus. Pseudanthonomus includes comparatively 
few species, and they are all of small size. P. nubilosus has very strongly unguiculate 
anterior tibie, and it may have to be separated eventually from this genus. 
a. Surface simply pubescent. 
a’. Femora each with an acute submedian or median tooth. 
a’’, Posterior tibize only curved in the ¢; scrobes lateral. . . . . . . . Species 1. 
6’. All the tibiz curved in the g; scrobes descending . ... . . . . Species 2. 
* Chelonychus appears to be wrongly placed in his table, the hind tibie not being unguiculate, according 
to the description.
