Colombia . 



The "type" of Ischyrus gratiosus Guerin-Meneville was 

 not studied; its current location is unknown. Guerin- 

 Meneville stated in the original description that the 

 species came from Colombia. 



Specimens examined . A total of 40 specimens, 

 representing 36 collection records, was studied (see 

 Appendix C for specific data) . 



Distribution . Southern Mexico through Central America 

 to Venezuela, Colombia, Trinidad, and Tobago (Fig. 104) . 

 Dejean (1836) indicated it was from "Brasilia". Lacordaire 

 recorded it from Cayenne (French Guiana) . 



Etymology . incertus: Latin = doubtful. Perhaps 

 Lacordaire used this name to indicate an uncertainty about 

 its validity. Its color pattern is nearly identical to I. 

 proximus Lacordaire and I. scriptus (Olivier) . 



Taxonomic notes . The identity of this species is based 

 on a female specimen in the Crotch Collection, label data: 

 "/ [green] Cay./ TYPE [crossed out] incertus C.Reiche/" 

 [CUMZ] . This specimen fits Lacordaire' s description, except 

 that the subhumeral spot touches the scutellar spot. 

 Lacordaire stated that these spots are separated; a 

 character found to be variable in this species. 



The second label on this specimen indicates it came 

 from Reiche's collection, which Lacordaire studied. Whether 

 this specimen was actually studied by Lacordaire is not
