REPORT OF THE STATE ENTOMOLOGIST I908 "JJ 



American Entomological Society. 1868, volmr.e 2. where the de- 

 scriptions of H . o p a c u 1 u s ail 1 II. s c a b r i p e 11 n i ^ a[)pear, 

 Dr Zimmerman begins his description of H . tenuis as follows : 

 "H. tenuis [Hylastes tenuis Eich. Berl. Ent. Zeit. 

 1868, 147]." Also Leconte. in the same paper \see p. 169, 173] 

 lefers to pages 147 and 149 of P]ichhofT's article just mentioned. 

 There is therefore no question but that both Dr Zimmerman and 

 Dr Leconte had Dr EichhofT's pages 146 and 147 before them 

 when their descriptions of H . opaculus and H. scabri- 

 p e n n i s were written. 



In regard to the use of the names Ips, Tomicus, and Hylastes, 

 perhaps a few words will be jjardoned. The genus Ips was erected 

 in 1775 by De Geer, Dermestes typographus Linne 

 being the first species described. All the other species included by 

 De Geer in the genus Ips have since been removed to other genera, 

 therefore leaving typographus as type. 



In 1802 Latreille described the genus Tomicus, including the 

 single species, Hylesinus piniperda Fabr., wdiich would 

 therefore be the type. 



In 1807 Latreille referred Dermestes typographus 

 Linne to the genus Tomicus, and gave a description of the genus. 



In 1836 Erichson erected the genus Hylastes with Bostrichus 

 ater C^rHylesinus piniperd'a Fabr.) as the type. 



Until recently Ips De Geer, 1775, seems to have been disregarded, 

 and the name Ips has been applied to a genus of beetles of the 

 family Nitidulidae. Tomicus Latr., 1802, has also been disre- 

 garded. Tomicus Latr., 1807, has been used for the allies of 

 typographus and Hylastes Er., 1836, for the allies of ater. 

 Ips De Geer, 1775, has therefore priority over Tomicus Latr., 1807, 

 and Tomicus Latr.. 1802, has priority over Hylastes Er., 1836. 



The name Ips Fabricius, of the family Xitifluliflac, dates from 

 the year 1776 [Fabricius, Gen. Ins. p. 23]. 



If the above synonymy is correct, and I believe it to be, it is 

 better to adopt it at once, even at the risk of temporary confusion. 



Following Bedel [Faun. Col. Bassin Seine, Rhyn. 1888], Hy- 

 lastes is dropped in this paper and the terms Ips and Tomicus are 

 used as indicated above. 



GeofTroy's name Scolytus dates from 1762. and therefore can 

 not be accepted. In 1776. O. F. Mullcr [Zool. Dan. Prodr. ■^-j'\, 

 described Scolytus p u n c t a t u s which is certainly not a 

 scolytid: "Niger, thoracc fossulato. elytris lineis quatuor elevatis.
