Ah now i get it. So the definition of the "-1, -2" character set, is in my syntax. So my syntax would look like this..
"8=1Capitalized&lower-3lower-4charNoSymbols.hcmask" being the "?2?l?l?l?1?1?1?1" .hcmask
Code:
cd /usr/share/cudahashcat/ && ./cudaHashcat64.bin -w 3 -t 10 -m 2500 /root/capture.hccap -a 3 -1 ?l?u?d -2 ?u?l /usr/share/cudahashcat/masks/8=1Capitalized&lower-3lower-4charNoSymbols.hcmask
"8=1Capitalized&lower-3lower-4charNoSymbols.hcmask" being the "?2?l?l?l?1?1?1?1" .hcmask
