Herbert Jordan Adams (1838 – 1 March 1912) was an English entomologist.
Following the death of his mother and the sale of her house and land at Chase Park, Enfield, Adams moved to a nearby house, Roseneath,[1] and amassed 68 cabinets and some 600 cartons of European and World butterflies.
He employed Percy Ireland Lathy to curate the collection and describe the new species it contained.
His collection of British Lepidoptera was bequeathed to the Enfield Entomological Society, of which he was a co-founder.
The main collection, containing very rare species of Papilionidae, Ornithoptera, Morpho, Agrias, Catagramma, Prepona, and Charaxes, was given to the Natural History Museum where it is now conserved.
