ACALLES, 473 
1. Acalles rugirostris, sp.n. (Tab. XXIII. figg. 9, 9a, 2.) 
Elongate-ovate, robust, opaque, black; thickly clothed with brown scales intermixed with a very short, stout, 
abundant setosity, the upper surface slightly variegated with fulvous, the elytra with a small transverse 
mark on the disc below the base and the apical declivity brownish or fulvous, and also with four velvety- 
black patches at the base (two on each elytron) and some black streaks towards the apex, the legs closely 
setose. Head and rostrum densely, rugulosely punctate; antennee in the ¢ inserted near, and in the 2 
at about one-third from, the tip of the rostrum, joints 1 and 2 of the funiculus subequal in length, 
3-7 short, the club ovate. Prothorax broader than long, constricted and much narrowed in front, and 
also narrowed behind, the base subtruncate; closely, finely punctate, the disc flattened and slightly 
hollowed, obsoletely carinate about the middle. Elytra oblong, constricted at the base, and there slightly 
wider than the prothorax, broadly produced at the apex (the latter emarginate in one specimen), the 
humeri rectangular ; seriate-punctate and finely granulate, the interstices 2, 3,5, and 7 subcostate, 
3 swollen or tuberculate at the commencement of the apical declivity. Mesosternum raised above the 
level of the metasternum. Ventral segments opaque, closely punctate, 2 transversely depressed at the 
middie and as long as 3 and 4 united. Femora unarmed. Tarsal claws rather long and divergent. 
Length 73-94, breadth 33-44 millim. (¢ 2.) 
Hab. GwuatTemata, Quiché Mountains and Volcan de Agua 7000-9000 feet 
(Champion). 
Four specimens. An elongate, robust form, of about the same size as 4. apicalis, 
Boh., with the surface opaque, squamose, and setulose, the apices of the elytra broadly 
produced, the rostrum rugulose to the tip, the tarsal claws long, &c. The sete on the 
prothorax are clustered into two fascicles at the apex. 
2. Acalles latescens, sp.n. (Tab. XXIII. figg. 10, 10 a.) 
Broad-ovate, opaque, black, the antenne and the tips of the tarsi rufo-piceous ; clothed with rather coarse, 
scattered, fulvous scales, which become much more numerous on the head and along a broad space on 
the outer part of the elytra (a large, common, triangular space on the disc of the latter remaining almost 
bare), and also set with a rather abundant short, semierect, setosity—the sete on the prothorax blackish 
and thickly clustered at the sides and along two curved lines on the disc, and grouped into two fascicles 
at the apex, those on the elytra more scattered, blackish and ochreous intermixed ; the legs closely sctose. 
Head and base of the rostrum rugulosely, and the rest of the latter sparsely, punctate ; antennz inserted 
behind the middle of the rostrum, joint 2 of the funiculus rather shorter than 1, the club ovate. 
Prothorax much broader than long, abruptly narrowed and strongly constricted in front, and slightly 
narrowed behind, the base shallowly bisinuate, the anterior portion tubulate; closely, finely punctate, 
carinate, feebly binodose at the apex. Elytra rather short, scarcely wider than the prothorax at the 
base, rounded at the sides, transversely convex, flattened on the disc anteriorly ; finely seriate-punctate, 
the interstices broad, sparsely granulate, 2, 3, 5, and 7 interruptedly raised or subcostate, the granules 
becoming stouter and seriately arranged towards the sides, as well as along the suture. Ventral 
segments opaque, closely punctate, 2 as long as 3 and 4 united. Femora feebly unidentate. 
Length 6, breadth 33 millim. (@ 2) 
Hab. Guatemaa, Las Mercedes 3000 feet (Champion). 
One specimen, perhaps partially abraded. A peculiar species, of broad-ovate form, 
with a fasciculate, carinate, anteriorly constricted prothorax, and comparatively short, 
proad, granulate, interruptedly subcostate elytra.
