These rare words, with eta as the second vowel, must be variants of u(mnopole/w and u(mnopo/los; cf. upsilon 118 and Nicander, Alexipharmaka 629, with scholia.
See also (and more generally) upsilon 112, upsilon 114, upsilon 115, upsilon 116.
[1] Present active imperative, third person singular, of the verb u(mnopole/w, attested only here and in similar lexicographical entries (Hesychius upsilon189, Synagoge upsilon30, Photius upsilon53 Theodoridis, etc.); evidently quoted from somewhere.
[2] Attested only (in the vocative case) in one anonymous dedicatory epigram: Anthologiae Graecae Appendix 214.1.
