270 On the JVomendature of the Family Scolytidse. 



1775, there is no rule whereby the oldest generic name must 

 necessarily be used tor the family; so that the name Ipidae 

 can quite properly give place to the much more generally 

 known one o£ Scolytus. 



Tti a recent publication (Entomologisch. Berichten, cxxvi. 

 Deel vi., 1 Juli, 1922) Herr Oberforster Eggers states that 

 he cannot agree witii me that Stephanoderes coffece^ Haged., is 

 a synonym of St. hampei, Ferr., and in support of his 

 opinion quotes an abstract from the original diagnosis of 

 Ferrari (Die Forst- und Baumzuchtschadlichen Borkenkafer 

 Wien, 1867, p. 12), and another from EichhofF's description 

 (Eatio, Descriptio, Emendatio eorum Tomicinorum, p. 153). 

 Both authors state the elytral clothing to be ^^ setae," the 

 original adding the qualifying word " crassis/' whilst Eichhoff 

 calls them " obtusiusculus tamen non clavatis." Ferrari 

 further emphasizes the absence of " schuppenborsten " (when 

 comparing his species with Cryphalus rafzhurgi^ Ferr. ; 

 Hagedorn stating the setse of his species St. coffece to be 

 *^ nicht keulenformigen," and later on differentiates his 

 species from St. hampei as having, inter alia, elytral hairs 

 that are even less scale-like. 



In Eichhoff's key to the genus he separates St. cassice from 

 St. hampei chiefly by the former having " setis subclavatis " 

 and the latter " baud clavatis.''^ A sptcimen of St. hampei 

 in my possession from Cliapuis's collection, and which he 

 probably received from Eichhoff, shows the set^ to be very 

 slightly broadened ; but in a speciuien lent me by Herr Eggers 

 for examination, and which he tells me has been compared 

 with a probably {'' wahrscheinlich") typical example, I found 

 the seta3 to be widely broadened as in St. cassice and other 

 species, and I wrote to Herr Eggers pointing out the discre- 

 pancies between our specimens and suggesting further inves- 

 tigation. At present I am of the same opinion as before, as 

 from time to time a large number of specimens have reached 

 me, and they are certainly similar to the description given by 

 Ferrari and to my Chapuis specimen. 



XylehoTus fornicatus, Eichh.,and X. fornicatior, Eggers. 



In the many long series of X. fornicatus that have passed 

 through my hands there have been differences of size and 

 consequent variations in the length of the elytral curve from 

 base to apex, but no specimens that could be said to have a 

 flattened appearance ; and in the description given by Eichhoff 

 (who is generally most accurate and painstaking) he takes 

 particular trouble to differentiate the species from X. xanthopus 

 by, inter alia, the fact that in the latter species the curve is
