with regular series of evident, though lightly impressed and somewhat remote, punc- 
tures, and on the declivous part with erect sete. Hind tibiz with a definite space 
at the apical truncature, formed by the divergent spinules. First ventral suture feebly 
arcuate in the middle, about equal in length to the second and third together ; sutures 
extremely deep; apical segment with an indefinite raised glabrous space along the 
middle near the apex. One specimen. 
2. Amphidees nubilosus. (A. curtus, Tab. IV. fig. 14.) 
Amphidees nubilosus, Boh. in Schénh. Gen. Cure. vi. 2, p. 253°. 
Brevis, convexus, squamosus; elytris quam prothorax multo latioribus, seriatim punctatis, interstitiis latis, 
subconvexis, posterius hispidis. 
Long. cumque rostro 7 millim. 
Hab. Mexico !, Parada, Capulalpam (Sad/é). 
Rostrum rather slender in the middle, separated from the head only by a feeble 
convexity of the latter, and without elevations or grooves. ‘Thorax much narrowed in 
front and strongly rounded at the sides. Scutellum quite minute. LElytra with broad 
base, and without trace of any margin even near the scutellum; shoulders greatly 
rounded. Male with an impression on the middle of the basal ventral segment. ‘Three 
specimens. 
Though so different in form from A. major, I cannot detect any distinctions of a 
generic character, except minute modifications of structure. 
A. nubilosus is figured on our Plate under the name of A. curtus; but having now 
received a type of A. nubilosus from Schénherr’s collection, I find our insect to belong 
to that species. 
3. Amphidees —— ? 
Hab. Mexico, San Antonio de Arriba (Sallé). 
I refer to this genus a pinned example of a very small species, resembling A. nwbi- 
losus, but having the elytra finely striate and the interstices quite flat. 
4. Amphidees macer, sp. n. (Tab. IV. fig. 15.) 
Angustus, elongatus, tenuiter squamosus, parce pilosus; prothorace elongato; elytris striatis, striis parum 
argute punctatis, interstitiis latis, levissime convexis. 
Long. cumque rostro 10 millim. 
Hab. Mexico, San Antonio de Arriba (Sal/é), Toluca (Hoge). 
Covered with scales, some of which are jewel-like, more especially on the head, 
rostrum, and thorax; also with scanty, fine, long sete. Rostrum with a convexity 
distinct from that of the head. Thorax elongate, with some very distant, rather fine 
punctures scattered between the scales. Elytra slender and elongate, with moderately
