Narrative:
It was the last leg of a long week of flying for the night cargo airline. We were inbound on the bonham 1 STAR to dfw. I was flying, first officer. I interpreted the STAR to read 'turn to 180 degrees at --- intersection.' after approximately 10 seconds on a 180 degree heading the controller told us to turn to a 240 degree heading and asked why we had turned early. He stated another aircraft had turned early at this point just a few mins earlier. He also stated that there was no problem. He just wanted some clarification. After further review of the STAR, I realized that I had misread it. I had turned at a point that was designated for non turbojet aircraft. I should have turned approximately 10 mi later. The STAR has quite a few intxns with blocks of instructions, with arrows pointing to the corresponding intersection. The STAR is not very easy to read. I also believe that fatigue was a factor in this situation.

Title: FLC OF A DC8-54 TURNED EARLY WHILE ON A STAR ARR DUE TO MISREADING THE STAR NOTES. ATC INTERVENED AND CORRECTED THEIR TRACK.
Narrative: IT WAS THE LAST LEG OF A LONG WK OF FLYING FOR THE NIGHT CARGO AIRLINE. WE WERE INBOUND ON THE BONHAM 1 STAR TO DFW. I WAS FLYING, FO. I INTERPRETED THE STAR TO READ 'TURN TO 180 DEGS AT --- INTXN.' AFTER APPROX 10 SECONDS ON A 180 DEG HDG THE CTLR TOLD US TO TURN TO A 240 DEG HDG AND ASKED WHY WE HAD TURNED EARLY. HE STATED ANOTHER ACFT HAD TURNED EARLY AT THIS POINT JUST A FEW MINS EARLIER. HE ALSO STATED THAT THERE WAS NO PROB. HE JUST WANTED SOME CLARIFICATION. AFTER FURTHER REVIEW OF THE STAR, I REALIZED THAT I HAD MISREAD IT. I HAD TURNED AT A POINT THAT WAS DESIGNATED FOR NON TURBOJET ACFT. I SHOULD HAVE TURNED APPROX 10 MI LATER. THE STAR HAS QUITE A FEW INTXNS WITH BLOCKS OF INSTRUCTIONS, WITH ARROWS POINTING TO THE CORRESPONDING INTXN. THE STAR IS NOT VERY EASY TO READ. I ALSO BELIEVE THAT FATIGUE WAS A FACTOR IN THIS SIT.
