6. Spintherophyta violacea. 
Ovately-rounded, black, the antenne and tarsi fulvous; above dark violaceous; head and thorax opaque, the 
latter remotely and very finely punctured; elytra closely and semiregularly punctured, the interstices at 
the sides convex. 
Length 13 line. . 
Head not longer than broad, minutely granulate and opaque; eyes notched ; labrum fulvous ; mandibles very 
robust and prominent, obscure fulvous; palpi flavous, the terminal joint piceous, elongate, and cylindrical ; 
antenne not extending much beyond the base of the elytra, pale fulvous, the terminal joints moderately 
and gradually thickened; thorax transverse, more than twice as broad as long, the sides rounded and 
narrowed in front, the angles distinct but not produced, the surface opaque, minutely granulate, and very 
remotely and finely punctured, the punctures only visible under a strong lens; elytra short and broad, 
more shining than the thorax, rather strongly and closely punctured, the punctures arranged in irregular 
rows, the interstices near the lateral margin convex; underside and legs black, the latter robust, the apex 
of the tibie and the tarsi dark fulvous; prosternum broad, subquadrate.

The species of this genus described below agrees well in its structural characters with 
the type, which is from the Amazon region. Ischyrolampra is allied to Spintherophyta, 
but differs from it in the dilated terminal joints of the antenne. 
1. Ischyrolampra panamensis. (Tab. XL. fig. 12, 3.) 
Fulvous, above pale metallic greenish; thorax very finely and rather closely punctured ; elytra very closely and 
finely punctured in rows, the interstices at the apex subcostate. 
¢. Antenne with the terminal six joints strongly dilated. 
¢. Antenne much less strongly dilated ; elytra longitudinally costate at the sides. 
Length 14 line. 
Head broad, the eyes widely separated and entire, the vertex finely and rather closely punctured, the interspaces 
extremely minutely granulate, the surface pale fulvous with a more or less strong metallic green gloss ; 
the clypeus transverse, its lower edge moderately concave ; labrum and palpi fulvous, the terminal joint 
of the latter fuscous, rather elongate, subcylindrical ; antennee fulvous, the apical joints fuscous, the sixth 
to the eleventh joints gradually and strongly dilated, the apical one more elongate, emarginate near the 
apex ; thorax transverse, the sides nearly straight and narrowly margined, the anterior margin sinuate 
behind the eyes, the posterior angles acute and pointed, the surface transversely convex, finely punctured, 
of a pale metallic greenish colour much suffused with fulvous ; scutellum smooth ; elytra slightly widened 
towards the apex, subcylindrical, scarcely more strongly punctured than the thorax (except at the sides), 
the punctures arranged in rather close rows which show a tendency to form pairs, the interstices near the 
lateral margin and at the apex costate; underside and legs fulvous, the latter robust, the femora very 
strongly inerassate, the first joint of the posterior tarsi longer than the following one; claws appendiculate ; 
prosternum narrowed between the coxe, its lower margin slightly concave. 
Hab. Panama, Tolé, Pefia Blanca (Champion). 
The ground-colour of this insect is pale fulvous, but the entire upper surface has a 
pale metallic green gloss; the female, besides having much less strongly dilated
