Page 8. 1823-4. — Say. Harris's Collection contains 
s]iecimens named in MS. by Say and himself. Eph. 
(Baetis) eurinus, Say, MS., Massachusetts, is Hexagenia 
limhata ^; but the Aving is yellow throughout, and the 
anterior femur yellow with only a little black spot outside 
at the tip. I received from Texas ^ $ of a very similar, 
perhaps new, species ; but I do not now find sin-e specific 
characters. 
Baetis amoenicauda. Say, ]\IS., Massachusetts, is B. 
fcmorata, AValsh 5 im. Perhaps my old opinion that 
Walsh's species are not those of Say is right. 
Baetis costalis, Har., MS., Maine, is Hex. limhata $. 
Baetis maculipennis and maculata, Har., MS., INIaine, 
are JE. decora, Hag. $ $ subim. I am not quite sure 
about their identity Avith my I^. natata or Walsh's decora. 
Baetis reticidata, Har., JSIS., Massach. and Alabama, 
is 2 subim., new to me. 
Baetis terminalis, Har., MS., Maine, is Leptopld. 
nehulosa i. 
Baetis bispinosa. Say, MS., Massachus., is Leptophl. 
cupida, subim. 
Baetis descri])ticostata, Say, MS., Dublin, New Hamp- 
shire, is B. unclata $ . 
Baetis tenella, Har., MS., Maine, is Heptag. maculi- 
pennis. 
B. fuscicostata, confiisa, irregularis, luteipennis and 
leuconeura. Say, ISIS., of his catalogues, are destroyed.
