Venezuela, the latter extending into Central America. This insect has a 6-jointed 
funiculus, a very uneven prothorax, broad, gibbous, tuberculate elytra, and short legs, 
the femora each with a single tooth, the anterior and intermediate tibie with a strong 
claw, the tarsal claws with a long tooth. Schénherr and Lacordaire omit to note the 
form of the scrobes, which (in B. gibbosus) are short and evanescent, as in Cionistes.

Botanebius gibbosus, Faust, Stett. ent. Zeit. 1893, p. 825 ‘ 
Subovate, robust, black, the antenn, the base of the femora, the apex of the tibise and the tarsi rufo-testaceous ; 
densely clothed with fulvous and greyish pubescence, the latter condensed into a narrow median vitta on 
the prothorax, the vestiture of the under surface in great part greyish-white. Head rugulose, faintly 
foveate above the eyes, the latter not prominent; rostrum stout, slightly longer than the head and 
prothorax, shining, finely, closely punctate; antenns inserted far before the middle of the rostrum, joints 
1 and 2 of the funiculus elongate, 1 as long as 2and3 united. Prothorax broader than long, transversely 
gibbous at the middle of the disc, much narrowed and subtubulate in front, strongly bisinuate at the 
base, densely, finely punctate. Elytra broad, gibbous, one-half wider than the prothorax, trisinuate at 
the base, subparallel before the middle, transversely depressed behind the scutellum, the humeri obliquely 
truncate and prominent; punctate-striate, the interstices more or less convex and rugulose, 3-6 and 7 
each with one or two more or less prominent oblong elevations—3 with two about the middle, 4 and 7 each 
with one at or near the base (that on 7 forming the prominent humeral callus), and 5 with one at the middle 
and another towards the apex, the suture arched in the centre. Femora each with an acute tooth ; 
anterior tibie triangularly dilated at the middle within. 
Length 3-4, breadth 12-23 millim.*

We possess three specimens of this species, varying in size and in the development 
of the prominences on the upper surface; one of them (? ¢) has the rostrum densely 
pubescent to near the tip. In the larger examples the posterior lobe of the prothorax 
is emarginate in the middle. 
Dr. Heller has been kind enough to compare one of the Honduras examples with 
the type, which is of the male sex. 
CIONISTES. 
Cionistes, Dietz, Trans. Am. Ent. Soc. xviii. p. 187 (1891). 
A genus hitherto including a single species from California. The Guatemalan insect 
now added agrees with it in having short, descending, evanescent scrobes, a 7-jointed 
funiculus, and appendiculate tarsal claws, as well as in general form, &c.; but the 
elytra in C. brevis are somewhat lobed at the base and without tubercles. 
1. Cionistes brevis, sp.n. (Tab. IX. figg. 6, 6a, ¢.) 
Broadly obovate, convex, comparatively short, slightly shining, piceous, the anterior margin of the prothorax, 
and the antenne and legs in part, ferruginous ; clothed with fine greyish or fuscous pubescence, which 
* The measurements of this and the following species of Anthonomina are taken from the anterior margin 
of the prothorax to the apex of the elytra.
