This species would not have merited distinct mention as more than a geographical 
variety of the IZ. paradoxa from Chontales, if it had not presented a structural peculiarity 
of great systematic importance. Whilst 1. paradoxa has no trace of the raised thoracic 
lateral margin which is one of the few distinctions of the Prionine as a subfamily, this 
evidently geographical variety of the same immediate stock has the margin distinctly 
indicated, and, further, denticulated, as is usual in Mallaspis. As evidence of its 
varietal condition, it is more or less developed in the different individuals. In sculpture 
and colour there is no difference between the two forms, except that in I. insignis the 
antenne and legs are dull bronze-brown or castaneous, and present very little of the 
rich violet lustre of the same organs in I. paradoxa. 
The locality Costa Rica, given on p. 11 for I. paradoxa, must be erased, and the 
specimen in question referred to the present species.

Received from Van Patten, from Costa Rica, together with numerous examples of the 
male. It has a totally different facies from the male, owing to its elongate-oblong and 
more convex form and glabrous scutellum.
