AMUS.—ZATUS. 445 
JEMUS, gen. nov. 
Rostrum moderately stout, very feebly curved, the scrobes descending to the lower limit of the eyes, but well- 
separated beneath, the eyes large, rounded, lateral, coarsely facetted ; antenne inserted towards the apex 
of the rostrum, the funiculus 7-jointed, closely articulated, widening outwards, the club stout, oblong- 
ovate, with deep sutures; prothorax much narrower than the elytra, with prominent ocular lobes ; 
scutellum oblong, small; elytra with ten rows of punctures; prosternum short, deeply excavate in front 
for the reception of the rostrum; anterior cox moderately, the intermediate cox widely, separated ; 
mesosternum depressed and concave, the sides not raised in front; metasternal side-pieces narrow ; 
ventral segments 1 and 2 connate, 3 and 4 short, together about as long as 5 and much shorter than 2 ; 
legs elongate ; femora clavate, sharply dentate ; tibie truncate at the apex, the inner apical angle feebly 
mucronate, the outer apical angle sharply unguiculate ; tarsi with joint 3 broadly bilobed, the claws simple 
and divergent. 
The single species from which the above characters are taken has somewhat the 
facies of an Anchonomorpha of the group Hylobiina. It is, however, a true Cryptor- 
rhynchid, and must be placed near Conotrachelus. 
1. Abmus tuberosus, sp.n. (Tab. XXII. figg. 2, 2 a.) 
Oblong, alutaceous, opaque, black, the knees and antennew reddish in one specimen; the elevations of the 
upper surface clothed with decumbent, blackish, setiform scales, the head, the lateral prominences of 
the prothorax, and the outer edge of the humeri with fulvous scales, the under surface and legs sparsely 
squamose, the latter also shortly setulose. Head finely punctate; rostrum about as long as the prothorax, 
shining, very finely, sparsely punctate; funiculus with the outer joints transverse, 2 shorter than 1. 
Prothorax a little broader than long, abruptly narrowed from about the middle, the sides parallel behind, 
the base bisinuate; finely punctate, the disc with two setigerous prominences at the middle, a smaller one 
on each side near the outer margin, and two at the apex. LElytra considerably wider than the prothorax, 
subparallel in their basal half, the humeri rounded ; seriate-punctate, the punctures oblong in shape and 
not hidden by the vestiture, the dorsal interstices (the first excepted) each with a series of prominent, 
oblong, widely scattered, setigerous tubercles. Beneath alutaceous, closely, finely punctate. Femora 
bidentate, the cuter tooth small and placed at some distance from the larger one. 
Length 34-53, breadth 14-23 millim. 
Hab. Panama, Volcan de Chiriqui 2500-4000 feet (Champion). 
Two specimens, differing greatly in size, their sex not ascertained. ‘The elevations 
of the upper surface are very conspicuous, owing to the setiform scales being clustered 
upon them, the scales becoming fulvous in colour on the lateral prominences of the 
prothorax. 
JEATUS, gen. nov. 
Rostrum short, curved, the serobes descending, very narrowly separated beneath; antenne with the funiculus 
7-jointed, closely articulated, 3-7 gradually widening, the club oblong-ovate, with distinct sutures ; head 
globose, almost smooth, the eyes large, contiguous or narrowly separated, coarsely facetted, and somewhat 
depressed; prothorax with feebly-developed ocular lobes, much narrower than the elytra; scutellum 
small, oblong; elytra with nine rows of punctures and a short tenth row at the base; prosternum 
excavate on each side in front, with a very deep rostral canal, the walls of the cavity sharply raised 
throughout and extending beyond the anterior coxe, the mesosternum convex or subcarinate along the 
middle; metasternum short, the side-pieces very narrow ; anterior and intermediate coxee somewhat widely 
separated, the latter hollowed within ; ventral segments separated by well-defined sutures, 3 and 4 together 
slightly longer than 2; legs short and stout; femora sulcate beneath, the anterior pair, at least, dentate ;
