Trying to boost viewership for "New Girl" and "The Mindy Project," Fox will air episodes of the comedies in a special timeslot following "American Idol" on April 4.

"New Girl" will air at 9 p.m., with "The Mindy Project" (pictured) airing at 9:30. The specially scheduled episodes will air in the place of a previously scheduled "Glee" repeat.

Currently, the series run Tuesday nights, in a lineup that received a jolt last month when the freshman comedy "Ben and Kate" was pulled from the schedule. In the absence of "Ben and Kate," the shows have been preceded by one-hour installments of "Raising Hope," except this Tuesday, when a repeat of "New Girl" immediately preceding them.

Both shows suffered ratings declines with their most recent airings Tuesday night, with "New Girl" dropping 15 percent from two weeks ago to a 2.2 rating/6 share in the key 18-49 demographic, and "The Mindy Project" dropping 16 percent to a 1.6/4. (Both shows were preempted by coverage of the State of the Union Address the week before.)
