There appear to have been at least three plays by this name over the years (plus various films, novels, etc.), two plays from the mid 1890s, and one short play for schools from the 21st century:

The New Boy: a comic farce by Arthur Law

Arthur Law (1844-1913)[1] was apparently inspired to write the play by F. Anstey’s popular book Vice Versa. The New Boy opened at Terry's Vaudeville Theatre, London, on February 28, 1894, with Weedon Grossmith (1854-1919) in the leading role, and finally closed in April 1895. The first American performance of was in Bethlehem, Pennsylvania, on September 14, 1894.

The posters for Law's play are speculated to have been the source of the famous Mad Magazine cover image of "Alfred E. Neumann". (See the entry on this in Yesterday's Papers, an inspiring blog by cartoonist, illustrator and storyteller John Adcock at http://john-adcock.blogspot.com/2013/03/the-face-of-new-boy.html.)

This seems to the best known and most thoroughly and frequently documented of the two 19th century farces.

The New Boy: a comic drama by R.R.Lumley

There are far fewer references to this play than there are to the work by Law. According to Allardyce Nicoll (1975:p. 464)[2], the play by Ralph R. Lumley (1864–1900) first opened in Margate in the UK on 22 April, 1893 (then known as Under Suspicion), before it premiered as The New Boy on 29 May 1893, also in Margate.

Another reference to Lumley's play occurs on the website on the Lakewood Theater in Maine, USA[3], which lists a 1910 production of a play called The New Boy by Ralph R. Lumley - but gives no further detail.

The only South African source on what appears to be Lumley's play seems to be a discussion by F.C.L. Bosman (1980, p. 403, citing D.C. Boonzaier), who ascribes the play performed in South Africa by the Ernest Searelle Comedy Company to "R.R. Lumley". Given the fact that Bosman and/or Boonzaier almost certainly have the name of the company wrong (it is probably the Luscombe Searelle Comedy Company), it is quite possible of course that this could also have been Law's text.

The New Boy: a short play by Andrew Beattie

This is a short play of 20 minutes duration with an all-male cast; it’s a ghost story set in an English boys’ boarding school.
