Beetle identification question
 

In San Antonio. Found a biggg beetle on my patio (dead). Searching on
internet I located one that looks very similar, called an Asian Longhorn
Beetle. Here's a link to a picture/drawing of one.

There are tons of links, and all picture and describe the same as above.
But the one I have seems to have a bit more obvious white marks on it.
All the links describe the antennae as black segment, then white
segment, then black segment, etc. My beetle has solid black ones which
are longer than the beetle's body.. Quite a few of the links in a
Google search sound alarmist and say if you find one you should report
it to...(who?). What do you think?
