A correspondant writes that he has been in contact with Maria Pantelia of the TLG about works of Cyril of Alexandria which are not yet in the TLG. He’s sent me the list that he sent in, which is useful anyway as a guide to works by Cyril and their editions. By permission I reproduce it here.

Scholia de incarnatione Unigeniti
Portions of this text are only preserved in Latin, but there are quite a few Greek fragments that are extant
Patrologia Graeca 75.1363-1412
Pusey, Epistolae tres oecumenicae etc. (Oxford, 1875), 498-579

PG 76.255-292

Contra Julianum imperatorem
You currently have online books 1 and 2 which were published by Burguiere and Evieux in the Sources chretiennes series, but don’t have books 3-10 which are extant in their entirety. They are printed in PG 76.509-1058
I believe that additional fragments are also published by J. Neumann, Iuliani Imperatoris librorum contra Christianos quae supersunt (Scriptorum Graecorum qui Christianam impugnaverunt religionem quae supersunt) (Leipzig, 1880), 42-63
Homiliae diversae
You already have 8 of the 22 of these homilies included on the site. The ones that you are missing are 1-8, 10, 13, 15-16, 19, 22. Note, however, that ns. 10, 11, and 13 are usually regarded as being spurious.
All of the sermons can be found in PG 77.981-1116.
Also Pusey, St. Cyrilli in d. Joannis evangelium, vol. 3 (Oxford, 1872), 452-476, 538-545 includes some new fragments, and several are included in Acta Conciliorum Oecumenicorum I, I, ii, 92f; I, I, iv, 14f; I, I, vii, 173; I, I, ii, 102.
Epistulae
Cyril has quite a few extant letters. PG 77.401-981 includes 88 letters, though some are spurious and 17 are actually letters addressed to Cyril. Some of these appear to be on TLG, but most are not.
Five additional letters were published by Schwartz: Konzilsstudien II (Strasbourg, 1914), 67-70; Neue Aktenstücke zum Ephesinischen Konzil 431 (Munich, 1920), 52f, 57f, 67f, 75f.
A number of the epistulae are scattered throughout Tome I, Volume I of Acta Conciliorum Oecumenicorum.
Also, Pusey published an edition of three of the letters: Pusey, S. Cyrilli epistolae tres oecumincae etc. (Oxford, 1875), 2-53.
Responsiones ad Tiberium diaconum sociosque suos
You have an older version of this text on the site. There is a newer and more up-to-date version in Wickham, Cyril of Alexandria: Select Letters (Oxford, 1983), 132-179
Solutiones
Again, you have an earlier version of this on the site. A better and newer edition is included in Wickham, Cyril of Alexandria: Select Letters (Oxford, 1983), 180-213
