I then oxprcssod. I know of no family of limited extent which 

 atfoi'ds a ìjetter basis for tlie study of (leneric differences. Strong 

 as the general resemblance of the insects composing this family 

 is, they break u)) into little natural groups distinguished by the 

 possession of more than one structural cliaracter. Twenty five 

 species of this family were found l)y Mr. L. Fea, pertaining to 

 nine genera ; of these fifteen species are presumaljly described 

 for the first time, and one genus Coptolanguria is characterised 

 as new, while three of my proposed genera find ample confir- 

 mation in tlie material now before me. 



The Erolylidae and Endonii/chidae if not on the wlujle j)re- 

 senting any remarkable difference from what is already known 

 from trojiical Asia, are at all events a very com})lete represen- 

 tation of what may be expected in any one district, and one or 

 more features, as the occurence of Dapsa , are instructive, as 

 shewing that prolmbly no genus of the Fjidoniijchidde is of 

 Europaean origin, but are only the outlying representatives of 

 a very restricted tropical development. It is o])servable in this 

 connection that the Languriidae, while represented in nearly the 

 whole world besides, are wholly absent from the Palaearctic 

 region, 



LANGURIIDAE.

The elytra are black in the two examples sent me, they are 

 steel-blue in the Sumatran specimens.
