116 COLEOPTERA. 



from the following additions to our list, SLc, that this newly 

 acquired light has been turned to good account. 



With reference to the Trichopterygid^e generally, I may 

 remark that Mr. Matthews (who has had many of the 

 continental collections of this family sent for his revision) 

 informs me he has spent the greater part of this year in 

 making complete dissections of all the genera, even to the 

 most complicated structure of the ligula and labium. 



It is, surely, a good cause for satisfaction, that — after the 

 comparative failure of Erichson, Gillmeister, and other 

 distinguished continental Coleopterists— it should have been 

 reserved for our countryman to succeed in operations of so 

 exceedingly delicate and difficult a nature.

" Castaneous-brown, oblong, rather broad, very convex, 

 "clothed with a golden pubescence, covered with rather 

 " large tubercles disposed in interrupted transverse rows, 

 " with the interstices rather deeply alutaceous ; legs and 

 '^ antennae long and stout." In the male the thorax is 

 slightly contracted towards the base. 



Mr. Matthews states that this new species is very rare 

 in Europe, but appears to be quite common in America, 

 where many specimens were taken in various parts of the 

 country by the late Dr. Schaum : — he has hitherto seen only 

 two British examples, taken by himself or his brothers in 

 Oxfordshire.
