ADEPHAGA. 















reunite. They are distributed over the tropical and subtropical regions of America, 

 Africa, and Asia (to the exclusion of Australia and oceanic islands). The genus 

 Peronoscelis is founded on a character (paraglossse not embracing the upper angles 





















of the ligula) which is not supported by other points of structure or by facies, and, 

 judging from Dr. Horn's dissections of Tetragonoderus, is not constant.

The pallid yellow belts of the elytra are much broader than in the most developed 

 examples of T. sinuosus, although dentated on the edges in a similar way to that species. 

 But T. intermixtus differs by having a third pale belt across the coppery-brown central
