REPORT OF THE STATE ENTOMOLOGIST 1908 i 
American Entomological Society, 1868, volume 2, where the de- 
scriptions of H. opaculus and H. scabripennis appear, 
Dr Zimmerman begins his description of H. tenuis as follows: 
Paemucwnis, Pkiylastes tenuis Eichy ‘Berl, Ent.) Zeit 
1868, 147].” Also Leconte, in the same paper [see p. 169, 173] 
refers to pages 147 and 149 of Eichhoff’s article just mentioned. 
There is therefore no question but that both Dr Zimmerman and 
Dr Leconte had Dr Eichhoff’s pages 146 and 147 before them 
when their descriptions of H. opaculus and H. scabri- 
pennis were written. 
In regard to the use of the names Ips, Tomicus, and Hylastes, 
perhaps a few words will be pardoned. The genus Ips was erected 
t7oeey Oe Geer, Dermestes typographus inne 
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., which would 
therefore be the type. 
inveice, Latreille referred Dernmrestes typographus 
Linné to the genus Tomicus, and gave a description of the genus. 
In 1836 Erichson erected the genus Hylastes with Bostrichus 
omer lesinus piniperda EKabr’) 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 Nitidulidae, dates from 
the year 1776 [Fabricius, Gen. Ins. p. 23]. 
If the above synonymy is correct, and I believe it to be, it 1s 
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. 
Geoffroy’s name Scolytus dates from 1762, and therefore can 
not be accepted. In 1776, O. F. Muller [Zool. Dan. Prodr. 57], 
described Scolytus punctatus which is certainly not a 
scolytid: ‘‘ Niger, thorace fossulato, elytris lineis quatuor elevatis,
