 Taxonomic notes . A lectotype was chosen for both I. 



frontalis Lacordaire and I. agnatus Crotch because no 



indication was made in the original descriptions that only 



one specimen was seen. 



Gorham (1887:39) stated he could not find any important 

 differences between I. frontalis and I. agnatus. After 

 studying the types of both species, I concur with his 

 synonymy . 



Remarks . Ischyrus frontalis is most similar to I. 

 dunedinensis in color pattern. Ischyrus dunedinensis is 

 distinguished by having the lateral elytral spots linear, 

 and longer than the central spot.

Diagnosis . Recognized by having 4 free pronotal spots 

 in a transverse row, a spot at each pronotal hind angle, 2 

 basal elytral spots set farther apart than the 2 central 

 free pronotal spots, and a central band transversely divided 

 by pale markings, except between stria V & VI .
