The Kentucky cave insects (Adelops) are evidently identical to European species of the same genus, some of which are cave insects, others found in damp, dark places.

Would like to borrow the bees that, as reported in Gardeners’ Chronicle, were sent to JOW with pollen-masses of orchids sticking to them. CD has never seen a bee visit an orchid. He believes he could identify the genus and perhaps species of the orchids the pollen comes from.

His health is too bad to attend the meeting [of British Association for the Advancement of Science].

Thanks JOW for the bees. The pollen-masses that were attached to one of them have unaccountably been lost.

Does not know of a paper by Charles Morren on orchids and insects, and would be glad to have the reference [see 3267, and Orchids, p. 270 n.].

Has spent so much money recently he is unwilling to subscribe for the purchase of T. V. Wollaston’s collection for the [Oxford] Museum.

As a general rule CD thinks it best to deposit specimens in the British Museum, and "bitterly regrets" he did not send all his specimens there. Nevertheless he agrees to sending his crustaceans to the Oxford Museum.

CD is at work on Orchids. He would be greatly obliged if JOW could send him specimens of pollen-masses attached to head or base of proboscis of moths.

Asks for reference to Morren’s paper that JOW mentioned before [see 2862].

Is certain he never had Morren’s paper from JOW or heard of it before JOW’s note; will write to Gardeners’ Chronicle about it [see 3252].

Thanks for the two Sphinx moths; unfortunately the pollen-masses do not belong to orchids but to Asclepias.

Asks whether R. B. Todd’s Cyclopedia of Anatomy and Physiology [1835–59] has an article on fertilisation of orchids.

Has found the reference to Charles Morren’s paper, "On the agency of insects in causing sterility in flowers" [Proc. R. Entomol. Soc. Lond. 1 (1836): xliv–xlv].

Common white butterflies remove pollen-masses with their tarsi from plants of the Asclepiadaceae.

Thanks for Orchids.

Has captured a bee with pollinia adhering to its head. Will send it to CD if he likes.

Asks JOW if he can see bee with pollen masses, and gives details for sending it by post or rail.

Bee with adhering orchid pollinia lent to Charles Daubeny. Pollen-masses shaken off but if CD still interested he is welcome to specimen.

Sends photo for B. D. Walsh; requests those of New World entomologists, and CD’s.
