 species. By George Charles Champion, F.Z.S.

Plate II. 



The present paper has been prepared to give an account 

 of the Malachiidae and Melyridae accumulated by the 

 Editors of the " Biologia Centrah- Americana " since the 

 completion of the supplement to the Rev. H. S. Gorham's 

 work on these insects, pubhshed in 1886. To determine 

 them the whole of the material in the British Museum 

 named by him has had to be re-examined, and the sex of 

 the specimens ascertained, before the descriptions of the 

 new forms could be drawn up. The other collections in 

 the National Museum, especially that of Fry, have also 

 furnished many novelties from Mexico. Tables of the 

 numerous species of the Malachiid genera Collops and 

 Attains, and of the Melyrid genera Trichochrous ( = Pristo- 

 scelis, Gorh.) and Lisfrus, are appended. For convenience 

 of reference the species here dealt with are renumbered 

 in the following pages. No fresh material has come to 

 hand of the genera Helcogaster (Malachiidae), and Cymbolus, 

 Eucymbolus, Astylus, and Antixoon (Melyridae), and they 

 are omitted from the present enumeration. Eucymbolus 

 and a new species of Cymbolus (elongatus) were described 

 by me in the Trans. Ent. Soc. Lond. 1913, pp. 128- 

 130. The genera Micromimetes, Pseudattalus, Psewdebaeus, 

 Sphinginus, Dasytellus, and Mecomycter are additions to the 

 Mexican or Central American fauna.
