 whereas the lectotype of D. femoralis has a prominent spot. 



It is possible that this specimen is mislabeled. Because of 



the difference between the lectotype and specimens from 



Mexico and Central America, the name "femoralis" cannot be 



used in reference to them. Dacne femoralis Chevrolat is 



placed in full synonymy under I. scriptus (Olivier) . 



Specimens from Mexico and Central America, lacking the 

 posterior pronotal angle spot, are referred to as 

 "northern". Specimens from South America with the posterior 

 pronotal angle spot are referred to as "southern". These 

 color pattern differences have no nomenclatural status. 



The lectotype of Ischyrus velatus Lacordaire was found 

 to differ from the description of I. scriptus Lacordaire 

 only in head color, and in the type locality; I. scriptus 

 with orange epistome and frons is from Brazil, I. velatus 

 with black head is from Colombia. Head color was found to 

 be variable even within the same population. Based on this, 

 I. velatus Lacordaire is placed in synonymy under I. 

 scriptus (Olivier) . 



The type of Ischyrus maculiventris Lacordaire was found 

 to be a malformed specimen. The dimples alluded to by 

 Lacordaire in the original description were found to be 

 depressions in the pronotum caused by outside forces. 

 Lacordaire even stated that they may be accidental. Crotch 

 must have realized this when he synonymized I. maculiventris 

 Lacordaire under I. scriptus (Olivier) .
