My Dear Mr Darwin
I think I can get ♂ & ♀ of the Onitis furcatus & also males & females of two or three species of Geotrupes at Mr Janson’s (Dealer);1 he has promised to oblige us, but I must go to his place to select them as soon as I can spare an hour
Yours sincerely | H W Bates
These insects are very cheap—a few pence each for the more curious Geotrupes with conspicuous sexual differences— Would you like more than one or two species?
[♂ & ♀ in each—]
Typhæus English sp.—
Copris— not the [interl] English species
2 sp. of Geotrupes
& 4 [after del `3 or'] *or 5 [interl] other genera or subgenera *— Those wch differ little & [illeg] which the appearance [is sexual] | some differing [more & some differing little by] [illeg] [added pencil]
Chiasognath [added pencil]
HWB thinks he can buy specimens of male and female insects at Mr Janson’s.
