former especially, more or less distinct, by which the genus is distinguished from Babia 

 — although these characters are not always recognizable at first sight, the prosternuum 

 especially being difficult to distinguish on account of its being almost hidden from view 

 by the head. 



1. Urodera crucifera. 



Urodera crucifera, Lacord. Mon. p. 454 *. 

 Babia crucifera, Dej. Cat. 3rd ed. p. 441. 



Hab. Mexico 1 ; Guatemala, San Geronimo, Duerias {Champion). 



The numerous specimens sent by Mr. Champion vary in length from 3 to 4J lines, 

 and have either the basal fulvous spots of the elytra interrupted by the suture or 

 extending entirely across the disk. As the entire difference between this and the 

 following species lies, according to Lacordaire, in the greater width of the thorax in the 

 former, I must refer all the specimens before me to U. crucifera, as the thorax is 

 distinctly broader than long. 



2. Urodera hcepfheri. 



Urodera hoepfneri, Lacord. Mon. p. 455. 

 Hab. Mexico. 



3. Urodera godmani. 



Urodera godmani, Jacoby, P. Z. S. 1879, p. 775. 



Oblong-ovate, black, shining, beneath closely pubescent ; head and thorax finely punctured ; elytra finely 



punctate-striate, black, a transverse band at the base, not touching the suture, and the apex rufous. 

 Length 3-4 lines. 



Hab. Guatemala, Duenas, Capetillo {Champion). 



It is not improbable that this species may be but a variety of U. crucifera, Lacord. 

 The differences lie in the distinctly punctured thorax, especially visible near the anterior 

 and lateral margins, and in the punctured striae of the elytra, which are not uneven as 

 is the case, according to Lacordaire, with U. crucifera ; the interstices also between the 

 striae are in the present insect very finely punctured. 



4. Urodera chevrolati. 



Urodera chevrolati, Lacord. Mon. p. 456 *. 

 Babia chevrolati, Dej. Cat. 3rd ed. p. 441. 



Hab. Mexico 1 . 



This species is difficult to distinguish from the two preceding ones, as it has some of 

 the characters belonging to each ; but the ely tral "black band is generally much narrower, 

 and, instead of being placed at or before, is situated behind the middle.
