MONOGRAPH OF THE COLEOPTEROUS FAMILY PAUSSID. 
PART II. 
Tue three following species, constituting the like number of 
genera, form a peculiar section in this singular family, possessing, 
in the number of joints in their antennz, an intermediate character 
between the Cerapteri and more typical Paussi and Platyrhopali.

This pretty species was described by Professor Kollar from a 
unique specimen in the Vienna Museum, brought from India by 
Fitchel many years ago, and which is, I apprehend, the identical 
insect mentioned by Donovan in his Insects of New Holland, as an 
undescribed species of Cerapterus. My drawing is made from a
