2. Revision of the Japanese Species of the Coleopterous 

 Family Endomychida. By the Rev. H. S. Gorham, 

 F.Z.S., F.E.S. 



[Received November 29, 1887.] 

 (Plate LIII.) 



The expedition made by Mr. G.Lewis to Japan in 1880 and !88l 

 was the cau«e of a lar^e number of additions to the Colenpterons 

 fauna of tliose islands. The Endomychidse are a small but very 

 interesting family, and the new species now described show how 

 very incomplete our knowledge of some of these minor groups 

 are, aud what interesting forms we may expect to see when other 

 islands on the limits of tlie great contimnts have been equally well 

 explored. Mr. Lewis's stay was, from circumstances, necessarily 

 brief in many of the localities visited ; hence it is but reasonable to 

 believe that a longer stay v\ould have brought to light many new 

 species, especially in such genera as Cyanauyes, Stenotarsus, Chondria, 

 and allied forms, which live a more or less obscure hfe, and only 

 remain in the imago state for a few weeks. 



Compared with the number of species that are new, the numl)er 

 of new genera is large. This is sure to be the cf\?& in a fauna as 

 yet only jiartially known, and lying so isolated from the centres 

 whence most of the material which has been the basis of the systems 

 proposed has hitlierto come. Ectomychus and Chondria are not only 

 new as genera, but hardly find a place in the subfamilies as vet pro- 

 posed. The following is a complete list of Japanese Endomychidse : — ■
