21. Gelasma subrufescens Warr. and ab. ('■;) pallescens nov. 



Of this species, described by me from three specimens only, in the 

 Procecdiiiys of i lie United States JS'atioiuil Miixeum, vol. xxx. ji. 417 (loiiij), I 

 have lately seen a long series from Tingnri and La Oroya, Peru and Fonte Boa, 

 Ujijier Amazons ; in the majority of cases the dorsum is marked with a double 

 blackish spot on segments I! and 4, and often witli dark scaling beyond ; a single ?, 

 from Fonte Boa, is rather larger, with the abdomen tinged with red, and has -v 

 the antennae ])ectinated, but not so strongly as in the S . Tlie whole of those 

 specimens are dull olive-green, and opa(jne. Of the form which 1 ]iropose to 

 call ab. jKillesreiiS 1 have seen only four s|)ecimcns ; these are rather larger tlnm 

 typical nuhniffxrens, (|uitc jiale green, and semidiaphanous, with scarcely any 

 reddish tinge beneath ; but tliey all show traces of the dark dorsal spots. Of 

 these, two are from Ocone(ju(^ and one from Ija Union, H, Ilnacamayo, Peru ; 

 the fourth, from Sapncay, Paraginiy, shows the dorsal blotches well marked. 



Li the original ilescripfion " Underside ol' forewing ilull gray" is a niisjirint 

 for dnll rosy.
