Ok, so I have 3 adult blaberus discoidalis in a tank that are mating, and there is ONE B.Dubia female in with them. I just looked at them and the one female dubia is flipping an ootheca, can these 2 different roaches mate? I have had these roaches for a good 5-6 months now, when they weren't even matured yet. I do not know much about roaches, jsut trying to start a colony and have about 40 little ones now in a separate tank than the mating adults. Thank you guys!
Whoa, can anyone tell me how this is happening? (roach)

B. dubia are live bearers, the ootheca is infertile and she is basically ovulating. You should eventually see it all decayed and decomposing sooner or later on the substrate. It happens from time to time and with no male B. dubia around this is exactly what's happened.
Also, Blaberus spp mate with other Blaberus spp here and there but I doubt they would attempt to mate with B. dubia. I've never thrown them together, though.

Wait and see you never know if anything happened.
As a general rule, anything species within the same genus can reproduce (ex: salamanders, ligers, wolf/dog hybrids). They are almost always sterile due to usually getting three chromosomes and therefore "improper gene dosage". Bugs usually avoid this by having very differently shaped genetalia. i.e. the key does not fit the lock.
I do think the first answer you got was correct though. It's not a fertile egg. It'd be pretty cool if you got hybrid x man/ninja turtle style offspring.
