PHONIUS.—SYSTENODERES. 145 
PHONIUS. 
Phonius, Chevrolat, Mag. Zool. 1843, p. 11; Mémoire, 1876, p. 5. 
Apparently only distinguished from Colyphus by its more robust form and distinctly 
clubbed antenne. The only species yet described is— . 
1. Phonius sanguinipennis. (Tab. VII. fig. 24.) 
Phonius sanguinipennis, Chev. loc. cit. p. 12*, t. 107. 
Hab. Mexico, Chalchicomula ! (Sallé). 
The specimen figured is a single one in the Sallé collection from the locality quoted, 
which is, I think, the place, between Vera Cruz and the city of Mexico, where the 
type specimen was originally captured. It only differs from it in having a small sub- 
scutellar black spot. 
PCGiCILOCHROA. 
Pecilochroa, Chevrolat, Mémoire, 1876, p. 5; Gorham, Cistula Ent. 1876, p. 73. 
The typical species have the antenne clubbed, and have a short convex thorax and 
cylindrical body, singularly like Dasytes. One species (Clerus thoracicus, Oliv.) is found 
as far north as Canada. 
1. Pecilochroa cyanipennis. 
Cleronomus cyanipennis, Klug, Mon. p. 307°. 
Cleronomus dasytoides, White, Cat. Cleridz, p. 50’. 
Hab. N. America, California !.—Mexico?, Puebla (Sal/é), Guanajuato ( Dugés, coll. 
Sallé), San Luis Potosi (Dr. Palmer). 
The smaller specimens, which also have the elytra and (in one example) the thorax 
dark blue, are C. cyanipennis, Klug. Dr. Palmer took a series which all have green 
elytra ; and I have specimens from other parts of Mexico similarly coloured, and one 
equal to them in size, with the thorax blue. 
SYSTENODERES. 
Systenoderes, Spinola, Mon. i. p. 180. 
The single species of this genus is a smoother insect, and more convex and widened 
behind than any of the foregoing. It is only found in Mexico. 
1. Systenoderes amenus. 
Systenoderes amenus, Spin. Mon. i. p. 131", t. 8. figg. 1, 2. 
Hab. Muxtico 1, Cordova, Toxpam (Sallé). 
Apparently rare, but perhaps overlooked from its resemblance to some of the common 
Galerucide.
