530 RHYNCHOPHORA. 
Hab. GuateMAa, Calderas, Duefias (Champion). 
Two rather worn specimens. Recognizable by the large, approximate eyes. The 
vestiture is probably similar to that of MW. subfasciatus when the insect is in fresh 
condition. 
4. Memactes subfasciatus, sp.n. (Tab. XXVI. fige. 12, 12a, ¢.) 
Oblong-oval, shining, black, the antennz and the tips of the tarsi ferruginous; thickly clothed (when fresh) 
with intermixed ochreous, brownish-white, and fuscous scales, the light-coloured scales clustered into 
several irregular transverse patches on the basal half of the elytra and showing a tendency to form one 
or two subapical fascie, the elytral interstices each with a row of semierect sete, the legs with piliform 
scales. Head somewhat closely punctate, the eyes rather small, separated by about half the width of 
the base of the rostrum; the latter very coarsely punctate and longitudinally wrinkled at the base, with 
the apical half sparsely, finely punctate, smoother in the ?. Prothorax a little broader than long, 
rounded at the sides, narrowed and feebly constricted in front ; closely, coarsely punctate, with 
indications of a smooth median line. Scutellum minute or invisible. Elytra at the base a little wider 
than the base of the prothorax, oblong-oval ; with rows of large, approximate, subquadrate punctures 
placed in shallow striw, the punctures separated one from another by a small raised point, the interstices 
very narrow, raised, closely punctate and reticulate. Beneath coarsely, closely punctate. First ventral 
segment broadly depressed down the middle in the $. Anterior and intermediate femora feebly, and 
the posterior femora strongly, dentate. Posterior tibize mucronate at the inner apical angle. 
Length 44-54, breadth 275-25 millim. (¢ @.) 
Hab. GUATEMALA, Quiché Mountains, Calderas, Duefias, Zapote (Champion). 
Seven specimens, two only of which are in good condition. In this species the 
upper surface is variegated with light and dark scales, intermixed on the elytra with 
short sete; the elytra are finely granulate, with the raised interstices very narrow and 
more or less interrupted by the oblique reticulation. The eyes are less approximate 
than in I. perforatus, and not so widely separated as in VM ruficornis and M. pilosus. 
STASEAS, gen. nov. 
Head convex ; eyes large and coarsely facetted, subcontiguous or moderately distant ; rostrum curved, stout, 
not reaching beyond the middle of the anterior cox, the antenne inserted at or beyond the middle, the 
funiculus 7-jointed, the club ovate, with well-defined transverse sutures ; prothorax transverse, deeply 
bisinuate at the base, the median lobe prominent, the ocular lobes moderately developed, not covering 
the eyes ; scutellum minute or not visible ; elytra oblong, a little wider than the prothorax, with ten 
rows of punctures (the tenth abbreviated in S. pretipennis), the humeri not prominent ; mesosternum 
horseshoe-shaped or arcuate; metasternum moderately long, the episterna rather broad; ventral 
segments 2-4 subequal in length, the first suture somewhat curved ; legs short, rugose; femora 
subclavate, dentate, the intermediate and posterior pairs sulcate beneath, the posterior pair not reaching 
the apex of the elytra ; tibiw carinate, Strongly unguiculate at the outer apical angle ; tarsi with joint 38 
bilobed, the claws each with a fine tooth towards the base. 
Type, S. granulatus. 
This genus is nearly related to Apteromechus, Faust, from which it differs in the 
larger and more approximate eyes, the pluri-carinate tibiew, and the toothed tarsal 
claws. Five species are here referred to it, one of which is an abundant insect in 
Central America, and I have seen various other unnamed S.-American forms. The
