98 ENTOMOLOGICAL NEWS. [April, 



a limited insect fauna, which proved to be the case. About one 

 hundred species of Lepidoptera and four hundred of Coleoptera 

 were the result of our raid, and these were not obtained without 

 labor. 



Our headquarters was located near a saw-mill, with two ob- 

 jects in view — the greater facility of obtaining supplies, and the 

 prospect of securing many species of beetles whose pleasure it is 

 to complete the work of destruction once begun by the lumber- 

 men. With the wastefulness characteristic of those who gather 

 from an apparently inexhaustible supply, the upper, or even the 

 -whole trunks of hundreds of giant pines were left lying on the 

 -ground, a prey to the insects and the elements. Under the 

 .loosening bark of one of these fallen monarchs I began my search. 

 The first thing bottled was Cossonus piniphilus; these were always 

 Xo be found, and with them in greater or less numbers occurred 

 Tachys namis, Hister pimdiger, Plegaderus nitidus, Lasco7iotus 

 J>usillus and Hypophloeus siibstriahis. Other occasional finds 

 mnder bark were Rhyssodes haniatiis, Alindria cylindrica (very 

 •small), Bins estri'atus, Uloma lo7igula and Metaclisa margiiialis. 

 Buprestidae were here much more numerous than in the valleys 

 below. Chrysobothris cuprascens (hitherto reported from Colo- 

 rado and New Mexico) was beaten in numbers from pines, and 

 with them a few C. femorata and C. californica. The latter and 

 also the brilliant Melanophila gentills were taken dead from their 

 burrows in dead pine twigs. Melanophila intruF.a and Chryso- 

 phana placida were also beaten from pines. Specimens of Bu- 

 prestis maciiliventris and B. Iceviventj'is were taken flying near 

 the summit. I can perceive no differences other than color be- 

 tween these two forms, and their manner of occurrence indicates 

 specific identity. Buprestis fasciata turned up in sweeping the 

 low herbage beside the brook, and Dicerca hornii was dug from 

 dead alder stumps. On willows occurred Agriliis politus and A. 

 niveiventris; the latter was the more abundant, and several trees 

 were observed which had been seriously injured by its attacks. 

 The flowers of a large primrose yielded many Anthaxia (e?ieo- 

 gaster and AancBodera connexa, and promiscuous sweeping or 

 beating gave one specimen of Agribis angelicus, also several 

 Anthaxia deleta of both sexes, the male bright green and the 

 female olivaceous. 



The piles of lumber near the saw-mill prompted frequent visits,
