PHALIAS.—SCEDASUS. 605 
1, Phalias laticrus, sp.n. (Tab. XXIX. figg. 26, 26a.) 
Elongate-ovate, narrow, robust, moderately convex, flattened on the disc; opaque, piceous, densely clothed 
with pale brown scales, the prothorax and elytra much mottled with fuscous (the prothorax with a 
median vitta and three spots on the outer part of the disc pale brown, and the elytra with the fuscous 
markings condensed into a large irregular patch at the sides). Head and rostrum densely, rugulosely 
punctate. Prothorax gradually narrowing from the base, rounded at the sides anteriorly, densely, finety 
punctate. Elytra moderately long, gradually narrowing from near the base, produced at the apex, the 
humeri obtuse; finely punctate-striate, the interstices rugulose and feebly convex. Beneath densely, 
finely punctate, the sculpture almost hidden by the dense pallid vestiture. 
Length 3,4, breadth 14 millim. | 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen, in very fresh condition. 
SCEDASUS, gen. nov. 
Rostrum strongly curved, moderately long, widened outwards, triangularly dilated at the base, and sub- 
angularly explanate beneath the points of insertion of the antenne, the scrobes short and rapidly 
‘descending ; antenne inserted near the base of the rostrum, the scape short, strongly clavate, the funiculus 
7-jointed, 1.and 2 ‘about equal in length, 3.a little shorter, the club ovate; mandibles truncate at the 
tip ; eyes large, rounded above, well separated; prothorax with moderately developed ocular lobes, 
pisinuate’ at the base; scutellum rather large; elytra much wider than the prothorax; elongate- 
triangular, strongly sinuate at the base, set with setigerous tubercles; rostral canal reaching to the 
middle of the intermediate coxe, the prosternal walls sinuate, the mesosternum broad, subtriangular ; 
metasternum moderately long, the episterna broad; ventral segment 2 nearly as long as 3 and 4 united, 
_ the sutures straight ; femora dentate; tarsi rather slender, the claws simple. 
This genus includes a single species from the State of Panama. It is recognizable 
by the short dilated scape of the antenne, which are inserted in the subangulate 
lateral prominences of the rostrum, and near its base. The sculpture of the elytra is 
rather like that of an Anchonus. 
1. Scedasus muricatus, sp. n. (Tab. XXIX. figg. 27, 27a, b.) 
Oblong-ovate, shining above, black, the antenne and tarsi ferruginous; the upper surface sparsely, the 
head, legs, and under surface more densely, clothed with minute greyish and brown scales, the scutellum 
and the basal margin of the prothorax with ochreous scales; the prothorax and elytra also set with 
coarse, scattered, suberect, blunt, intermixed blackish and ochreous sete, which become more crowded on 
the dorsal elevations ; the legs sparsely, coarsely setose. Head rugulosely punctate, finely carinate down 
the middle ; rostrum stout, rugosely punctate at the base and sparsely, minutely punctate thence to the 
tip. Prothorax a little broader than long, abruptly narrowed and constricted anteriorly, the anterior 
lobe tubulate, the posterior lobe depressed around the carinate, setigerous, central prominence, and also 
obliquely depressed on each side; the entire surface closely, finely punctate, the flanks sparsely granulate, 
Elytra narrowing from the base, broadly produced at the apex, with rather prominent, rounded humeri; 
seriate-punctate, the interstices punctulate and set with scattered setigerous conical tubercles, 3 with an 
oblong setigerous elevation below the base, and 2 with a similar elevation at the middle, the sete at 
the apex of the latter entirely ochreous. Beneath opaque, densely, finely punctate. Femora feebly 
clavate, unidentate. Tibiee slightly sinuate within. 
Length 54, breadth 23 millim. (2?) 
Hab. Panama, Volcan de Chiriqui (Champion). 
One specimen, in rather dirty condition, and possibly with the scales discoloured.
