By "in series", do you mean "in sequence"?
If it's as AnalogKid stated, where the LEDs are all turned on together, then just a 4093 and transistor driver can give the flash and auto turn off. I suspect that's not what you're after; if you want a sequence of a single LED on, two LEDs on, ... all LEDs on, then all flash together, then all off, it can be done using an oscillator feeding a shift register (for the sequential lighting), followed by another oscillator to flash the LEDs, and a timer to turn everything off.
