The small Coccinellidæ commonly known as Smilia are among the more important natural enemies of the Coccidæ. The name Smilia properly belongs to a well-known genus of Homoptera, so in Science Gossip, 1900 p. 606, I proposed to call the Coccinellid genus Epismilia. I now learn from the Index Zoologicus that Epismilia was used in 1859 for a genus of Coelenterates. I therefore propose another name for Smilia, Weise, namely Microweisea. The North American species are Microweisea misella (Lec.), M. marginata (Lec.), M. coccidivora (Ashm.), M. ovalis (Lec.), M. atronitens (Casey), M. minuta (Casey), M. planiceps (Casey), Mreversa (Fall); all standing in our lists under Smilia.
