and Psciidophoraspis nebulosa Burin., from the Malayan région. 

 Dr. Hem Singh Pruthi, ol' the Zoologieal Survey of India, recently 

 sent me a i'emale of Phlebonotus pallens, with yonng nnder ils 

 wings, which he had captured in a smaJl stream near Yercand 

 (ca. 1350 m., Shevroy Hills, S. India). AÇ spécimen of Perisphaeria 

 «lomeriformis Lucas, from the Philippines, lent to me by Prof. 

 S.iostedt, also has nymphs clinging to its under surface.

This species is somewhat smaller than E. aurantium and can be 

 distinguished by the uniform orange head, the broad hyaline 

 margin of pronotum and tegmina, by the wings which hâve only 

 a small orange patch at the costal margin, and by the abdominal 

 sternites baving not only posterior, but also latéral white borders.
