You can use CTE for getting all last days of the month within the defined range

Declare @Start datetime
Declare @End datetime

Select @Start = '20130808'
Select @End = '20131111'
;With CTE as
(
Select @Start  as Date,Case When DatePart(mm,@Start)<>DatePart(mm,@Start+1) then 1 else 0 end as [Last]
UNION ALL
Select Date+1,Case When DatePart(mm,Date+1)<>DatePart(mm,Date+2) then 1 else 0 end from CTE
Where Date<@End
)

Select * from CTE
where [Last]=1   OPTION ( MAXRECURSION 0 )
