CLEODAUS.—PHYSCIUS. 101 
3 longer and much more slender than 2, 4 shorter and a little wider than 3, 5 very much wider than 4, 
5-10 very strongly transverse, angularly dilated within, and increasing in width outwardly, 7-10 nearly 
twice as broad as long, 11 the width of and twice as long as 10; prothorax transverse, immarginate, with 
distinct basal fovese ; scutellum strongly transverse; elytra very long, wider than the prothorax, widening 
to the middle and then narrowing to the apex; anterior coxe contiguous, the cavities open behind ; 
intermediate coxe very narrowly separated; legs rather short, moderately slender; claws towards the 
base angularly dilated within ; body very elongate, widest behind, rather depressed above; the rest as in 
Conomorphus. 
This genus is proposed for a single species from the State of Panama. The long 
and subcultriform apical joint of the maxillary palpi, differently formed antenne, and 
short thorax readily distinguish Cleodwus from Conomorphus, to which it is closely 
allied. The form of the antenne approaches that of Stilpnonotus and Eurypus, but in 
both these genera joints 4-10 of the antennz are dilated within; in Cleodeus joints 
5-10 only are widened, and 3 and 4 are more slender than 2 or 5. The head is more 
narrowed behind than in Conomorphus. 
1. Cleodzus rugiceps. (Tab. V. figg. 5; 5a, labium; 50, maxilla and maxil- 
lary palpus. ) 
Piceous-black, sparsely clothed with brownish pubescence, slightly shining, the oral organs testaceous. Head 
densely and coarsely punctured, transversely flattened between the eyes; antenne black, the basal joint 
testaceous ; prothorax transverse, very little narrower at the apex than at the base, the sides slightly 
arcuate in front and almost straight or very feebly sinuate behind, the hind angles acutely rectangular, 
the disc with a large oblique rather shallow impression on each side about the middle, the base feebly 
bisinuate, the surface densely and very minutely punctured (very much more finely so than the head); 
scutellum densely punctured; elytra with traces of very shallow longitudinal grooves, densely, minutely, 
and uniformly punctured; beneath closely punctured; legs (including the coxee) testaceous, the tarsi a 
little darker in colour. 
Length 442 millim. 
Hab. Panama, Volcan de Chiriqui 3000 feet (Champion). 
Two examples, agreeing exactly with each other. The head is very much more 
coarsely punctured than the thorax or elytra and is transversely flattened or depressed 
between the eyes, the latter being less coarsely granulated than in Conomorphus. 
PHYSCIUS. 
Last’ joint of the maxillary palpi broadly triangular, its apical side very little shorter than the outer and 
about one third longer than the inner side, the inner angle subrectangular ; last joint of the labial palpi 
rather slender, elongate-pyriform, the narrow end outwards; mentum strongly transverse; mandibles 
entire at the apex; head inclined, large and broad, broader than the prothorax, narrowed behind, 
less abruptly so in the female, the epistoma not defined, the antennary orbits very little raised; eyes 
large, moderately convex, coarsely granulated, entire, occupying the whole of the side of the head, not 
very widely separated in the male, more distant in the female; antenne slender, extending a little 
beyond the base of the prothorax, joint 3 narrower and longer than 2, joints 4-10 angularly dilated 
within, 6—10 transverse, 11 nearly twice as long as 10, ovate, and with the apex rather blunt; prothorax 
transverse, immarginate at the sides, with distinct basal fovese; scutellum small; elytra moderately long, 
much wider than the prothorax, widening from the base to far beyond the middle, very obtuse behind ; 
anterior coxee contiguous, the cavities open behind but closed laterally; intermediate coxe very narrowly
