2. Revision of the Japanese Species of the Coleopterous 

 Family Endoinychida. 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 1881 

 was the cau'^e of a iar^e number of additions to the Coleopterous 

 fauna of those islands. The Endomychidee 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 the great continents have been equally well 

 explored. IVIr. 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 Cynnauc/es, Stenotarsus, ChonJria, 

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

 remain in the imago state for a few weeks. 



Compared with the number of species that are new, the number 

 of new genera is large. This is sure to be the ca.=e in a fauna as 

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

 whence most of th.e material which has been the basis of the systems 

 ])roposed has hitherto come. Ectomyclms 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 Jaj)ane^e Endomychidse : —
