scribed by Kerremans from Colombia, but differs from that species by 
having the pronotum entirely green, the scutellum brown, and the 
anterior green fascia on the elytra not extending around the humeri. 
LEIOPLEURA CONTIGUA Waterhouse. 
Leiopleura contigua WATERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, 
1889 p. 154, pl. 9, fig. 2. 
Described from material collected by Mr. Champion at Volcan de 
Chiriqui, Panama, at an altitude of 3,500 feet. This species is some- 
what variable in color, and Waterhouse describes the typical form 
as having the elytra dark purple, head and pronotum green, with the 
median part of the pronotum brownish-black. A second specimen 
collected at the same locality differs from the type by having the 
head and entire pronotum black. ‘The species is not represented in 
the National Collection and is placed in the key solely upon the char- 
acters given in the original description. 
LEIOPLEURA POLITA Waterhouse. 
Leiopleura polita WatERHOUSE, Biol. Centr.-Amer. Coleopt., vol. 3, pt. 1, 1889, 
p: 162; pl. 9, fig. S. 
The type locality of this species is Bugaba, Panama, and the type, 
which is in the British Museum, has not beenexamined. The species 
is convex, elongate, and strongly attenuate posteriorly, and in form 
resembles parvula, but differs from it in color. It is placed in the 
key upon the characters given in the original description. 
LEIOPLEURA MUTABILIS, new species. 
Oblong, feebly convex, broadly rounded in front, broadly attenu- 
ate posteriorly, and slightly narrower behind than in front, moderately 
shining; head and pronotum dark cupreous, with a slight greenish 
reflection; scutellum brownish, with an obsolete cupreous tinge; elytra 
obscurely reddish-purple, with a strong greenish tinge on the disk, and 
the sides near the humeral angles narrowly margined with violet; 
beneath piceous. 
Head feebly convex and broadly depressed on the front, the de- 
pression rather deep at the middle, but becoming obsolete near the 
epistoma and on the vertex, with a distinct, narrow, longitudinal 
groove extending from the epistoma to the front, where it is abruptly 
ended; surface coarsely and rather sparsely punctate; intervals 
densely and finely granulate-striolate; antennae rather short and 
entirely piceous. Pronotum moderately convex, two and one-half 
times as wide as long, narrower in front than behind, widest near 
the base; sides nearly parallel to basal fourth, then strongly, ar- 
cuately attenuate to the anterior angles; posterior angles feebly 
projecting and rather acute; anterior margin broadly, arcuately
