Dated 14. Julii 1740. Sent from Leufsta (Sweden) to Stockholm (Sweden). Written in Latin.

Viro Doctissimo,
D[omino] CAROLO LINNAEO,
Doctori Medicinae,
S[alutem]P[lurimam] D[icit]
Carolus de Geer.

Accepi Epistolam Tuam et summa cum animi satisfactione perlegi illam. Est mihi summum gaudium, observationes meas de Poduris, a Te verificatas esse. Sed credo, tuas Poduras rubras nihil aliud esse quam pulli, ut rectius tu ipse existimes.

Gratias ago Tibi et Academiae nostrae pro misso Insecto perquam mirabili. Delineavi jam jam et describi [sic] illud summa cum diligentia. Est Cimex; habet proboscidem ad caput; alimentum ejus est, Muscae et alia Insecta, quae capit magna cum velocitate.

Neglexi metamorphosin observare istius Insecti, intra tria folia majora, totidemque minora Juniperi hospitantis.

Insectum, ramis Alni insidens copiosissimum, cauda fasciculum Gossypii villosum emittente &c., de quo mentionem facis in Epistola tua, accedit prope ad illud Insectum, quod caudae duos stylos habet, et a Gallis vocatur Puceron. Sed est Genus proprium; non habet istos stylos, et omnes per metamorphosin alis donantur, quod non contingit Puceronibus, ut Tibi notum sit.

Utinam velles curare, ut habeam unum Exemplar Historiae hujus Muscorum &c. charta puriora et nitidiora [sic]. Solve pro me, si places, et Tibi proxime restituam!

Aliam Monoculi speciem detegi [sic] in aqua; descripsi etiam et delineavi, ut tibi monstrare vellem Stockholmiae, si Deo placet. Nam est mihi animus, illae [sic] redire hac septomana [sic]. Vale et saluta membra Academiae nostrae!

Dabam Leufsta, die 14. Julii 1740.

A Monsieur
Monsieur Charles Linnaeus
Docteur en Medecine
à
Stockholm.

upSUMMARY

Charles De GeerDe Geer, Charles (1720-1778).
Swedish. Entomologist and natural
history collector, Leufsta Bruk. Member
of the Royal Swedish Academy of Sciences
in Stockholm and Académie des
sciences, Paris. Corresponded with
Réaumur, Bonnet and other
naturalists. Husband of Catharina
Charlotta Ribbing and father of Emanuel
De Geer. Correspondent of Linnaeus.
thanks Linnaeus for a letter that he has received [this letter has not come down to us] and read with great pleasure. He is glad that his observations of Podurae have been verified, but he adds that some red Podurae mentioned by Linnaeus seem to be young specimens.

De Geer thanks Linnaeus and the Royal Swedish Academy of Sciences [Kungliga Svenska VetenskapsakademienKungliga Svenska Vetenskapsakademien,
Swedish. The Royal Swedish
Academy of Sciences, Stockholm. Founded
in 1739.
] for having sent him specimens of a strange insect. De Geer has depicted and described it. It is a Cimex, living from fleas and other insects. De Geer has not observed its metamorphoses, since it was hidden among leaves when that happened.

Linnaeus had mentioned another insect in his letter, and De Geer specifies what it can be. It is something that in French is called Puceron. It would seem to be close to the earwigs, but it is a separate species.

De Geer asks Linnaeus to buy a copy of Johann Jacob DilleniusíDillenius, Johann Jacob
(1684-1747). German/British. Studied at
Giessen. Sherardian professor of botany
at Oxford. Correspondent of Linnaeus.

for him. De Geer will refund Linnaeus immediately.

De Geer has discovered another Monoculus in water. He has depicted it and described it in order to show it to Linnaeus in Stockholm. He is returning there during the week. De Geer sends his greetings to the members of their academy .
