In slenderness of form intermediate between Chi. ( Ver- 
tar/2is) Buquetil and Chi. lynx ; the thorax being elongate- 
ovate, with obtuse angles, and aides very regularly ar- 
cuated, the widest part being exactly in the middle. The 
])alpi have the terminal joints of very extraordinary form 
(in the $ ) ; they are not triangular as in the allied spe- 
cies, but broadly rhomboidal, with the greater part of one 
surface (the upper?) excavated. The tooth of the men- 
turn is broad and simple. The fulvous spot of the elytra is 
similar to that of Chi. lynx and allied species, occupying 
interstices 4 — 8, and much broader on the fifth.

Very near Chi. deliciolus. The thorax is larger, with 
sides very regularly arcuated from base to apex, the 
broadest part in the middle, the hind angles rounded off, 
the surface minutely punctate-rugulose, the middle part 
occupied by a broad uneven black vitta, the sides broadly 
fulvous. The lateral pale vitta of the elytra occupies only 
the middle of the sides, the posterior sutural spot is small 
and hooked on each side.
