What is this?

After or in between Marguerites, Golden Waves, Gaillardias, Pinks, and Plains Coreopsis, these flowers were appeared.... But I don't know the name. Could you tell me if you know the name? I thought it Chocolate Cosmos, but the season seems to be a little early...







The second picture was taken with flashlight, and the third one was without it. The color observed by my eyes is brown, so I thought the red color on the picture is coming from the flashlight... but no???
