A fine series of this remarkable insect, of which I believe the above 

 synonymy to be correct, from Iquitos, Peru, March-May, 1920, and 

 Yurimagous, Peru, March 31, 1920. Many specimens without the 

 pronotum and many pronotums without bodies are represented, illus- 

 trating the habits of these insects of separating themselves from their 

 grotesque armor as described by Professor Mann for a closely related 

 species, Combophora beski Germar. (Mann, Wm. M., A Protective 

 Adaptation in a Brazilian Membracid. Psyche, XIX: 5, pp. 145-147, 

 PI. 12. October, 1912.)
