ACALUES. 475 
with two prominent rounded tubercles on the third interstice before the middle and several other 
scattered rounded or subconical tubercles towards the sides. Mesosternum very broad, feebly emarginate. 
Ventral segments sparsely, rather coarsely punctate, 1 and 2 connate, 5 long. Legs long and rather 
slender, the femora each with a small acute tooth. 
Length 3,,, breadth 12 millim. 
Hab, Guatumaa, Senahu in Vera Paz ( Champion). 
One specimen. In this small species the elytra are much produced at the apex and 
have four prominent rounded tubercles on the anterior part of the disc, the prothorax 
is broadly depressed and finely carinate down the middle, and all the femora are 
distinctly dentate. 
6. Acalles indutus, sp.n. (Tab. XXIII. figg. 14, 14a, ¢.) 
Oblong-ovate, shining (when denuded), black, the antennz and tarsi reddish ; somewhat thickly clothed with 
brown scales, with decumbent, very short, blunt, brown and whitish sete intermixed. Head and rostrum 
rugulosely punctate, the latter bare and a little smoother at the tip and subcarinate ; antenne inserted 
at about the middle of the rostrum, joint 1 of the funiculus rather longer than 2, 3-7 short, the club 
short-ovate. Prothorax nearly as long as broad, constricted and much narrowed in front, and also a 
little narrowed behind, subtruncate at the base; closely, finely punctate and subgranulate, the disc 
somewhat hollowed and with a short arched median carina. Elytra slightly wider than the prothorax 
at the base, comparatively short; seriate-punctate and granulate, each elytron with five large, oblong or 
rounded, prominences on the disc—two on the third interspace, placed near together, two on the fifth, 
widely separated, and one below the shoulder, projecting laterally. Ventral segments 1 and 2 subconnate, 
the suture arched, 2 and 5 subequal in length. Femora unarmed. 
Length 53, breadth 22 millim. (¢.) 
Hab. Guatemata, Cerro Zunil 4000 feet (Champion). 
One specimen, in dirty condition. The short arched carina on the disc of the 
prothorax separates this species from most of its allies, A. cinericius excepted, which, 
however, has dentate femora and smaller elytral tubercles. 
7. Acalles rufotuberculatus, sp.n. (Tab. XXIII. figg. 15, 15a, 3.) 
Oblong-ovate, narrow, convex, shining, black, variegated with ferruginous; thickly clothed with narrow 
sordid ochreous scales, with a few, fine, decumbent sete intermixed. Head and the base of the rostrum 
closely punctate and squamose, the rest of the latter bare and almost smooth ; antenne inserted behind 
the middle of the rostrum, joint 2 of the funiculus shorter than 1, the club stout, ovate. Prothorax 
about as long as broad, narrowed and constricted in front, hollowed in the middle at the base; densely, 
very finely punctate. Elytra gibbous, ovate, much produced at the apex, conjointly lobate and not wider 
than the prothorax at the base; rather coarsely seriate-punctate, the punctures placed in shallow striz, 
the third interstice with an elongate convex prominence at the base and another at the commencement 
of the apical declivity, the fifth also a little raised before the middle. Ventral segments very sparsely 
punctate, 1 and 2 connate, 3 and 4 very short, 5 long and depressed down the centre. Legs long, rather 
slender, the femora unarmed, the anterior tibia sinuate within. 
Length 31, breadth 13 millim. (¢.) 
oO 
Hab. Panama, Volcan de Chiriqui 8000 feet (Champion). 
One specimen. This peculiar little species may be recognized by the conjointly, 
anteriorly lobate elytra, and the two long red prominences on the third interstice, the 
3 PP 2 
anterior one extending to the base.
