The best match that I could find is 'Shemetitsa' from the [JewishGen Gazetteer][1].

It is listed as a 'populated place' with coordinates 51° 03'N 28° 26'E, which would place it within the [Volhynian governorate][2] in the north of modern Ukraine, about 2km SE of [Luhyny][3].

I've looked for it with a number of online maps, including [mapcarta][4], and [Google Maps][5] and there doesn't seem to be much there today.

Mapire have an [historical map of the area around Luhyny][6]. The map doesn't have a scale, and the place names use a Cyrillic script (plus the tape joining the sections of the map is irritating), but there is a settlement to the south-east of Luhyny that may be Shemetitsa.
