CAMPTODES. 329 
Closely allied to C. illustris, but may be distinguished by a glance at the colour 
of the sides of the thorax; the male possesses a peculiar character, inasmuch as the 
mentum and submentum, besides being pubescent, are finely punctate and opaque; the 
prosternum between the front legs is very broad. 
We have received seventeen specimens which come under the above definition ; it is 
certainly a variable species as no two individuals are exactly alike, and there is a great 
difference in size and colour between the extreme forms. The most remarkable variety 
is the one alluded to above, of which we have received one female example from Bugaba. 
Our figure represents a male found in British Honduras by Blancaneaux. 
This species was ticketed C. formosus, Blanch., in Sallé’s collection, but does not 
appear to have been described. 
5. Camptodes metallicus. 
Camptodes metallicus, Reitter, Verh. Ver. Brinn, xii. 1, p. 112°. 
Hab. Mexico 1, Cordova, Playa Vicente (Sallé). 
This species cannot be confounded with any other of the genus, owing to the brilliant 
unicolorous metallic colour of the upper surface. This colour in the examples before 
me is either blue, green, or golden. 
6. Camptodes morio. 
Camptodes morio, Er. in Germ. Zeitschr. iv. p. 225'; Reitter, Verh. Ver. Brinn, xii. 1, p. 103°. 
Hab. Mexico 2, Ciudad in Durango, Matamoros Izucar (Hége), Acapulco (H. H. 
Smith, Hoge), Tierra Colorada 2000 feet (H. H. Smith), Jalapa (Deppe', Hoge), Cordova 
(Sallé) ; Guatemana, San Gerénimo (Champion). 
Var. a. Subtus (cum abdomine et pygidio) pedibusque rufis. 
Hab. Mexico, Jalapa (Hége), Temax in North Yucatan (Gawmer); GUATEMALA, 
Zapote, Capetillo, Duefias, San Gerdénimo, Tocoy, San Juan in Vera Paz (Champion), 
Aceytuno 5000 feet (Salvin). 
Var, 8. Subtus cum pygidio rufus ; pronoto rufescente. 
Hab. Mexico, Tuxtla (Saiié), Jalapa (Hoge), Temax in North Yucatan (Gaumer); 
British Honpuras, Belize (Blancaneauz). 
I think there is no doubt that this is a single species variable as to colour (the 
variations being rather different in different localities) ; after prolonged examination I 
fail to find any constant character to distinguish the varieties, and the cedeagus of 
a typical specimen from Jalapa proves to be similar to that of one of the var. « from 
San Gerénimo. This insect in its typical form appears to be common at Jalapa, and 
there also varieties have occurred sparingly. In Guatemala the var. « is the prevalent
