For what it's worth, I just came across a letter that may be relevant to this discussion. One black Philadelphian wrote in April 1863 that he "was enrolled for the draft which will take place in about a month." He further noted that "Many colored people are alarmed and others declare if they have to go they will enlist in the Mass. Reg. as there is no provision made by this State for the families of colored soldiers." "Letters of Negroes, Largely Personal and Private [Part 1]," The Journal of Negro History, Vol. 11, No. 1 (January 1926), p. 84.

Many thanks to Prof Lysy for his excellent detective work. It confirms my suspicion that the policy JAMES Fry (not Speed--sorry about that) enunciated in December 1863 changed in early 1864.
Thank you all for a very interesting and enlightening conversation. For what it's worth, one of the men in our study of USCT soldiers from Albemarle County, VA, a man named James T. S. Taylor, was drafted into the army in 1863 while living in Washington, DC, and served in the 2nd USCT. He wrote a very interesting letter to President Lincoln (http://naucenter.as.virginia.edu/blog-page/311) during the war and went on to have an important career in Charlottesville, VA, politics after the conflict.
Prof Oakes writes: "Peter Lysy cites a communication from Speed Smith Fry, operating in Kentucky in December, 1863, but Mike Crane finds that free blacks were drafted in areas of Kentucky beginning in early 1864. Were Kentucky slaves likewise drafted beginning in early 1864?"
I have been reading the diaries of Emilie Davis, a free African American woman in Philadelphia. The diaries indicate that her brother Alfred was drafted in 1864. (He seems to have fled to Canada for a while before reporting.)
There are two new editions of Davis's diaries, one edited by Karsonya Wise Whitehead and another by Judith Giesberg and her students.
