Answer:
   
   Leviticus Rabbah (Vayikra Rabbah)
          This consists of 36 homilies on Leviticus, and was redacted
          sometime between 400 and 500 CE.
          
   Pesiqta de Rab Kahana (Verses of Rabbi Kahana)
          For a long time this work was only known by separate
          quotations, although recent scholarship has reconstructed the
          content and structure by piecing together more recently
          discovered manuscripts and fragments from the Cairo Genizah.
          This book is a homiletic midrash for the readings on the
          festivals and Sabbaths. The material contained within it was
          probably written between 500 and 700 CE.
          
   Pesiqta Rabbata 
          A collection of sermons for the festivals and Sabbaths. It may
          have been written sometime in the 6th or 7th century, but a
          more accurate dating still is impossible.
          
   Tankhuma (Yelamdenu)
          A homiletic midrash on the whole Torah. It probably was
          redacted around 400 CE.
          
   Devarim (Deuteronomy) Rabbah
          Consists of 27 self contained homilies that relate to
          Deuteronomy. Its core material was written before 400 CE, but
          later material was added until its redaction around 800 CE.
          
   Shmot (Exodus) Rabbah 
          The first part is an exegetical midrash on Exodus, while the
          second part is a homiletic midrash. It was redacted sometime
          before the 12th century, although it contains much older
          material.
          
   Bamidbar (Numbers) Rabbah 
          A haggadic and homiletic midrash on Numbers. Although its final
          form was reached around the 12th century, most of the material
          is probably from the 8th century.
