I copied this list from your other thread before I deleted it. There's really no need for you to have two seperate threads going about 1,000 point Tyranid lists:
<tt>HQ </tt>
<tt>1 Hive Tyrant 173 </tt>
<tt>Devourer, scything talons, winged, toxic sacs, toxic miasma, warp blast </tt>
<tt>Troops </tt>

<tt>6 genestealers 120 </tt>
<tt>extended carapace</tt>
<tt>16 Gaunts 96 </tt>
<tt>fleshborers </tt>

<tt>PTS: 1004</tt>
<tt>Models: 63</tt>
Now as for some commentary, you definitely seem to be getting away from your shooty theme, have you essentially abandoned it?
As for this last list, its better than the one before (which didn't have enough Synapse) it still has some problems.
Your Raveners should be split into seperate units for versatility.
Termagaunts are okay, but they aren't going to win you any games. They usually get only one shot off before they either charge or are charged, and you pay the extra 1 point for that slightly upgraded shooting (meaning you have less bodies then you'd have with Spinegaunts).
You also now only have one unit of Genestealers which makes them the prime target for any opponent. Once they're dealt with there isn't much else in your army that's very scary.
Also, why take Warp Blast on your Tyrant with a Devourer? You can't fire another weapon the same turn as you use Warp Blast so you're better off just going with the 2nd Scything Talon if you really want to take Warp Blast. Either way, you can't use Enhanced Senses with the focused Warp Blast so you have a sub-optimal configuration at best.
Really, you should either make your winged Tyrant either into a full
CC monster, or give him x2
TL Devourers, Enhanced Senses and Toxin Sacs and make him a mobile gunship.
