NEW BRITISH SPECIES, ETC., IX 1871. 83 



It appears to frequent birc]i, and sometimes oak, and to 

 be found in Algeria, Spain, and the south of France, being 

 rare near Paris. 



79. Tychius PYGMiEus, Brisout. 



hrevicornis, Waterhouse. 



Dr. Sharp, in his Catalogue, gives Mr. Waterhouse's 

 species precedence : but, as it was published in May, 1863, 

 and M. Brisout's in 1860, and I am not aware of any prior 

 described species named j)ygm<jous, there would seem no 

 reason for refusing priority to ^A. Brisout. 



The insect has been found by Dr. Power abundantly at 

 Weybridge, during the past summer. 



80. CEUTHORHYNCH(iDE)usCROTCHi,Ch. Brisout," L'Abe- 



ille," V (1869), 437; E. C. Rye, l. c, viii, 159. 



Described from England only, I do not know why this 

 species has hitherto escaped record in this country. It is 

 apparently very like versicolor, Ch. Bris. (quercicola, Wat. 

 Cat.), but distinguishable therefrom by its more depressed 

 prothorax, of which the anterior margin is less reflexed, and 

 by its testaceous tarsi, of which the claws are smaller.

Gen. et Spec. Cure, iv, 494; Bedt., Fauna Austr., 

 Ed. 2, 800; D. Sharp, Cat. Brit. Col.; Ent. Mo. 

 Mag., viii, 83. 



In Dr. Power's collection (taken in August, 1867, at 

 Hastings) ; confirmed by M. Brisout. 



Thomson (Skand. Col., vii, 256), whose views are usually 

 the reverse of synthetical, considers this insect to be a variety
