specimens of Corymbites cereipennis were obtained by rolling 

 logs. Dolopius lateralis and Megapenthes stigmosus were, of 

 course, common on flowers. It is worthy of remark that nearly, 

 or quite all, of these Elateridae are transcontinental in distribution. 



Numerous long horns were obtained, mostly representative 

 of species which are to be met with over the greater portion 

 of the forest-clad region of the northwest. Prionns californicus 

 and Ergates spiculatus were to be had by rolling pine logs, under 

 which they hide, and in which, no doubt, the larvae feed. The 

 male Prionus has enormously heavy antennae, the joints " shing- 

 ling" on each other in a manner not often seen outside of the 

 genus. The sexes of Ergates spiculatus are easily distinguished 

 by the fact that in the male the prothorax is very broad, finely 

 granulate and deeply foveate above, the sides armed with fine 

 teeth, while in the female this part of the body is much narrower 

 than the elytra, more coarsely granulated than in the male and 

 with much larger lateral teeth. The Prioninae, to which sub- 

 family the above genera belong, are remarkable among the long- 

 horns for the prominence of secondary sexual characters, and it 

 is interesting to note, among our own species, such curious 

 modifications. Tragosoma harrisii was rare under pine logs. 

 Several species of Leptura were found on flowers, the two most 

 abundant being L. crassipes and L. crassicornis now united as 

 sexes of the same thing. They frequented heads of umbellifer- 

 ous plants on low ground close to the lake, and, judging from 

 the rapidity with which my supply was exhausted, must previ- 

 ously have been quite rare in cabinets. L. obliterata was not 

 uncommon. Of L. canadensis two very fine varieties occurred, 

 namely erythroptera, in which the elytra are entirely red, and 

 tenuicornis. where they are quite black. 



Turning to the Chrysomelidae we find a most remarkable form 

 inhabiting the Cceur d'Alene district Timarcha intricata, the 

 only North American representative of a genus well developed 

 in Europe. This insect is to be obtained in moss or on low plants 

 under protecting logs; in appearance it resembles some Tene- 

 brionidae, especially a small Eleodcs, the likeness being heightened 

 by a peculiar rough sculpture very unlike most of our native 

 Chrysomelids. Its motions are slow, and from its habits it set-m> 

 one of those insects likely to disappear before approaching denu- 

 dation and cultivation of its haunts.
