 Variation . The holotype, illustrated by Gorham (1887), 



has the central elytral band broad, the other 2 specimens 



studied have the band much narrowed. This band is almost 



separated into 2 spots on the Mexican specimen. 



Type . The holotype (by monotypy) of Ischyrus 

 episcaphulinus Gorham label data: "/ [red circle on white 

 paper] Type/ Zapote, Guatemala, G.C. Champion/ Ischyrus 

 episcaphulinus/ B.C. A., Col., VII, Ischyrus/" [NHML, 

 studied]. Sex not determined. 



Specimens examined . The holotype and 2 specimens, 

 representing 2 collections, were studied. Label data: 

 Guatemala [1, NHML]; Mexico, Chiapas, Mpio. Mapastepec, 11.5 

 mi. N. Mapastepec, 12-VI II-l 991 , P. W. Kovarik [1, PESC] . 



Distribution . Guatemala and Mexico (Fig. 101) . 



Etymology . epi: Greek = upon, on; scaphion: Greek = 

 cup-shaped like a boat. The name refers to the body shape 

 of this species. As Gorham stated, it is "distinguished by 

 the very convex oval form" . 



Remarks . Pronotal markings are intermediate between I. 

 collatinus and the remainder of the species with the "2 

 free-3 basal" pronotal spot pattern. The shape of the free 

 pronotal spots is consistently different between the 

 species. In I. pictus, the free pronotal spots are 

 circular, and in I. collatinus the single free pronotal 

 spot is transversely linear.
