(Sallé), Misantla (Hoge, F. D. G.), Jalapa, Teapa in Tabasco (Hoge), Atoyac in Vera 
Cruz (H. H. Smith); British Honpuras, Rio Hondo, Belize (Blancaneaux) ; GUATE- 
MALA, Chiacam in Vera Paz (Champion). 
Var. The second discoidal spot and the two outer median ones coalescent, so as to form an irregular fascia on 
each elytron; the first and second discoidal spots often united with the sutural one, forming a common 
X -shaped patch. (Fig. 25.)

Hab. Mexico, Teapa in Tabasco (Sallé’, Hoge, H. H. Smith); British Honpuras, 
Rio Hondo (Blancaneaux); Guaremaua, Panzos in Vera Paz (Conradt), Chiacam in 
Vera Paz (Champion); Honpuras (Dyson, in mus. Brit.®"). 
_ This species is confined to the Atlantic slope. With the type of C. 17-notata, Boh., 
before me, Iam unable to separate it from C. comata, even as a variety; it merely 
differs from C. comata in having the elytral spots larger, the common sutural patch 
sometimes continued downwards and coalescent on either side with the second discoidal 
spot. C. smithi is a local variety, not uncommon in Tabasco, where also the var. 17- 
notata. occurs ; these two forms were also collected together at Rio Hondo and Chiacam. 
Boheman? compares C. smithi with C. catenulata; the latter, however, has the elytra 
much flatter, not at all gibbous below the base. We figure a variety (2) from Vera 
Cruz; one of Boheman’s types (¢ ) of C. 17-notata, from Playa Vicente, and one (¢ ) 
of his C. smithi from Teapa.

ix. p. 83°. 
Hab. Panama, Chiriqui (Ribde), David, Tolé (Champion), Matachin (Thiéme).— 
CoLomBIA; VENEZUELA2?; Brazin1~. 
_ A species readily recognizable by its rufo-testaceous or rufous elytra and black pro- 
thorax, the latter with the anterior margin, and sometimes a narrow streak on the 
disc, rufo-testaceous.

_ Hab. Costa Rica, Caché (Rogers); Panama, Bugaba, Volcan de Chiriqui, Tolé 
(Champion).—Cotomsia 1~* ; Amazons, Paré? 3, Santarem ? *. 
Not uncommon in Chiriqui. All our specimens, and also those named by Boheman 
in the National Collection, have a small black spot on either side of the disc of the 
prothorax about the middle. Some examples have a oroad indeterminate  flavous
