A FEW RARE BEETLES FOUND IN LOGS NEAR 
PASADENA 
On November 4th, while collecting along the margin of a small 
lake near Pasadena, California, I came upon a half dead willow, the 
dead part of which was full of "shot-holes" of borers. After hack- 
ing it open, one specimen of Ptilinus hasaiis was found dead in a 
burrow, and several specimens each of Teretrius placitus and Micracis 
hirtella. I have visited the same little glade three times since to 
examine the logs, and have been well rewarded for my trouble. The 
dates of these trips and the captures are as follows : 
November 11, 1916. — Two small weevils of an undescribed spe- 
cies and six specimens of RIyncolus spretus were found in a decayed 
stub, on which at some time termites had evidently been working. 
November 12, 1916. — Fourteen Micracis hirtella and several Tere- 
trius placitus were found in burrows. 
November 18, 1916. — Three Micracis hirtella and fourteen Tere- 
trius placitus in burrows. Two small Scolytids, probably of an un- 
described species, were found in a twig. They were immediately 
under the bark, and, having been unable evidently to chew their way 
out, were found dead and with microscopic fungi growing on them. 
Teretrius placitus is parisitic on P. hasaiis and M. hirtella. This 
accounts for its being found in the burrows. It seems to feed on 
these beetles in both larval and adult stages ; but little is known about 
this. I found three adults feeding on a dead P. hasaiis, which was 
about half devoured. ^ ALONZO DAVIS,

THE COLLECTOR AND HIS WORK 
The collecting of specimens is a very important part of the 
study in natural history in whatever branch we may be interested. The 
work of the collector is indispensable to science.
