‘SISENES. 137 
of them the second costa on the elytra is continued nearly to the apex, and in others it 
only reaches to about the middle ; the usual first costa is obsolete in all. , 
10. Sisenes viridipennis. 
Moderately elongate, finely pubescent, subopaque; the head bronze, the anterior part flavous, the labrum and 
the tips of the mandibles and of the palpi piceous; the prothorax yellowish-red ; the scutellum and elytra 
brassy-green or green. Head broader than the prothorax, densely and rather coarsely punctured, the 
eyes small; antenne black or piceous-brown, moderately long, filiform, rather stout, joint 2 nearly half 
as long as 8; prothorax a little broader than long, the sides moderately rounded in front and feebly 
constricted behind, the base grooved within, the disc shallowly transversely depressed in front, with a 
shallow oblique depression on each side behind the middle, and sometimes with traces of a smooth median 
line or ridge, the surface densely and finely punctured; elytra moderately long, parallel, densely and 
rather finely punctured, and with two fine coste on the dise and one at the sides, the two outer ones 
nearly reaching the apex and the inner one extending nearly to the middle, the suture also raised; beneath 
closely and finely punctured and pubescent, obscure neous, the prothorax coloured as above but with the 
lower part of the flanks zneous ; legs slender, piceous, the basal two-thirds of the femora, and sometimes 
the tibie in part, testaceous, the penultimate joint of the tarsi tomentose beneath. 
Length 42-53 millim. (9.) 
Hab. GuatTeMaLa, Sinanja in Vera Paz (Champion). 
Four examples. Closely allied to the Mexican S. telephoroides, and differing thus :— 
The thorax more densely and much more finely punctured (especially noticeable at 
the sides), the head also more finely and more closely punctate; the elytra green or 
brassy-green, and with the usual first costa distinct towards the base. 
11. Sisenes testaceipes. (Tab. VI. fig. 17, 2.) 
Moderately elongate, finely and thickly pubescent, opaque; the head and prothorax reddish-yellow, the eyes 
black; the scutellum flavous or piceous; the elytra brassy-green (in one example violaceous), the colour 
much hidden by the dense ashy pubescence. Head broad, a little wider than the prothorax, very closely 
and coarsely punctured, the eyes small; antenne moderately long, rather stout, filiform, reddish-yellow 
(in one example piceous-brown with the basal joint testaceous), joint 2 not half the length of 3, 11 very 
distinctly constricted beyond the middle; prothorax comparatively broad, transverse, the sides moderately 
rounded in front and feebly constricted behind, the base grooved within, the disc with a shallow oblique 
depression on each side behind the middle, an indistinct very shallow transverse depression on either side 
in front of this, and traces of a fine median ridge (the depressions almost, and the median ridge quite, 
obsolete in one example), the surface closely and rather coarsely punctured; elytra moderately long, 
parallel, densely and rather coarsely punctured, and with two fine cost on the disc and one at the sides, 
the two outer ones extending nearly to the apex and the inner one to about the middle, the suture also 
raised ; beneath closely and finely punctured and pubescent, obscure eeneous or violaceous, the head and 
prothorax reddish-yellow ; legs, including the coxe, flavous or reddish-yellow, moderately slender. 
Length 53-63 millim. (@.) 
Hab. Nicaracua, Chontales (Belt); Panama, Volcan de Chiriqui 4000 feet (Cham- 
pion). 
Two examples from Chiriqui and one from Nicaragua (the latter in a mutilated con- 
dition), apparently all females. The Nicaraguan specimen has the elytra violaceous and 
the antenne darker, but otherwise agrees with those from Chiriqui. The reddish- 
yellow head, oral organs, legs, and antenne, differently-coloured elytra, more transverse
