120 

 Specimens examined . The lectotype and 14 specimens, 



representing 12 collection records, were studied (see 



Appendix C for specific data) . 



Distribution . Guatemala, Nicaragua (Kuhnt 1909), 

 Panama, and Colombia (Fig. 94) . 



Etymology . collatus: Latin = gathered together, 

 collected. Possibly, this species was named for the single, 

 transversely linear, free pronotal spot, unique to this 

 species . 



Taxonomic notes . The Lectotype, from the Crotch 

 Collection, was chosen because Crotch made no indication 

 that he saw only one specimen. 



Remarks . Ischyrus collatinus is similar to I. 

 episcaphulinus and I. pictus in body shape and basic color 

 pattern. The number and shape of the free pronotal spots 

 will separate these species. Ischyrus episcaphulinus has 2 

 rectangular free pronotal spots. In Ischyrus pictus the 2 

 free pronotal spots are circular.

Diagnosis . Unique in Ischyrus by the pronotum having 

 only 3 basal spots, and a single large free spot on each 

 elytron.
