DEAPETES. 199 



The carina of the hind angles of the thorax will prove useful to group the species. 

 As a general rule, the elongate and maculate species have a sharply defined carina. 



The number of new Brapetes from the Guatemala and Panama regions is relatively 

 very large, and some of them cannot be made to associate with the species in de Bon- 

 vouloir's table; the following brief tabular arrangement of their more striking 

 characters will assist in their identification : — 



Sides of the elytra without supplementary marginal carina . . 2. 



Sides of the elytra with supplementary marginal carina ... 6. 



2. Prosternum bisulcate ; entirely black 1. aterrimus. 



Prosternum quadrisulcate 3. . 



8. Body uniform in colour 4. 



Elytra more or less marked with red or yellow 5. 



4. Entirely black 2. nigricans. 



Rufo-testaceous or castaneous 3. brunneus. 



5. Elytra with a transverse red band, more or less median ... 4. semirufus* ; 5. later- 



alis* ; 6. sellatus; 7. balteatus; 8. affinis*. 



Elytra merely tipped with black sellatus, var. apicalis. 



Elytra entirely rufo-castaneous sellatus ,var. cast aneipennis. 



6. Body above bicoloured or with ornate elytra 7. 



Body above entirely black 16. 



7. Thorax entirely black 8. 



Thorax not entirely black 14. 



8. Elytra transversely banded; no distinct carina at the hind 



angles of the thorax . 9. 



Elytra maculate or with a broad vitta or a whitish selliform 

 space, or red at the apex ; bind angles of the thorax 

 carinate 10. 



9. Oblong-oval ; the anterior edge of the elytral band parallel with 



the base of the abdomen 9. grandis. 



Elongate. 



Elytral band behind the middle, its anterior edge straight . 10. cingulatus. 

 Elylral band in front of the middle, its anterior edge on 



each side oblique and arcuate 11. semicinctus. 



10. Elytra with one or two oval spots on each 11. 



Elytra with a yellowish-white selliform space covering the 



greater part of the area 12. plagiatus. 



Elytra with a broad vitta on each, broadest in front .... 13. tceniolatus. 



Elytra red at apical fifth ; quite small species 23. hatmorrhoidalis. 



11. One spot on each elytron near the apex 14. bipustulatus. 



Two spots on each elytron . 12. 



12. Anterior spot at the humeral angle 15. quadrisignatus. 



Anterior spot posterior to the humerus 13. 



13. Basal depression of the thorax distinct and smoother .... 16. quadrimaculatus. 

 Basal depression indistinct, punctate 17. quadrinotatus. 



* These species are unknown to me and cannot satisfactorily be tabulated.
