more sparsely punctate in the 9. Prothorax transverse, narrowed and constricted in front; densely 
punctate. Elytra much wider than the prothorax, narrowing from before the middle ; shining, punctate- 
striate, the interstices rugulose and feebly convex. Beneath densely punctate. Femora sharply 
unidentate. Tibise more or less curved, the anterior pair sinuate within, the intermediate pair, and 
sometimes the posterior pair also, subangulate towards the middle externally. 
Var. Larger and more robust, the prothorax more dilated at the sides, the femora strongly clavate and each 
with a large acute tooth. 
Length 22-41, breadth 11-2} millim. (d 9.) 
Hab. Guaremata, Coban (Conradt) ; Nicaracva, Chontales (Janson) ; Panama, 
Bugaba, Volcan de Chiriqui, Tole, Pefia Blanca (Champion). 
Found in abundance in Chiriqui. In well-developed specimens the intermediate and 
posterior tibie are very distinctly angulate externally. Two from Bugaba are larger 
and have the sides of the prothorax more dilated and the legs robust, with the femoral 
tooth very sharp. 
2. Piseus complanatus, sp.n. (Tab. XXIX. figg. 7; 74, intermediate leg. ) 
Oblong-ovate, narrow, depressed, piceous, the elytra sometimes mottled with rufous, the antenne and the 
tips of the tarsi ferruginous; variegated above with pale brown (or yellowish-cinereous) and blackish 
scales, and also thickly set with erect light and dark sete, the vestiture of the under surface sparser, 
the legs setose. Head densely, the rostrum rugosely, punctate. Prothorax densely punctate. Elytra 
flattened on the disc, deeply punctate-striate, the interstices rugulose, becoming feebly convex towards 
the sides. Beneath densely punctate. Femora acutely unidentate. Tibi curved, the intermediate 
pair, and sometimes the others also, angularly dilated towards the middle externally. 
Length 23-8, breadth 13-13 millim. (¢ 9.) 
Hab. Panama, Bugaba, Volcan de Chiriqui (Champion). 
Many specimens, varying in the extent of the angulation of the tibie. ‘This insect 
is nearly related to P. varicus, but it is a little smaller and has the elytra more 
depressed. The pallid scales on the prothorax are condensed at the sides and down 
the middle. The shining elytral interstices (when the scales are removed) separate 
P. complanatus from P. sulcatus. One of the specimens from Bugaba is more 
elongate than the others, and has all the tibie broad and angulate. 
3. Piszeus sulcatus, sp. n. 
Subovate, rather narrow, nigro-piceous or black, the antenne and the tips of the tarsi ferruginous ; variegated 
above with fulvous and blackish scales, and also thickly set with moderately long, erect, blunt, light and 
dark sete ; the under surface and legs clothed with brownish or cinereous scales, the legs setose. Head, 
rostrum, and antenne as in P. varicus. Elytra much wider than the prothorax, flattened on the disc 
anteriorly ; punctato-sulcate, the interstices opaque, rugulose, and almost flat. Beneath densely punctate. 
Femora very sharply unidentate. Intermediate and posterior tibia angularly dilated towards the middle 
externally and slightly hollowed thence to the apex. 
Length 23-8, breadth 14-13 millim. 
Hab. Panama, Volcan de Chiriqui (Champion). 
Three specimens. Very like P. complanatus, but broader, the elytra more sharply
