He mentions searching Andreas ami Murray canyons wlicre 

 no dead palms were obtainable, and then goes on to say: 



"Finally I returned to Palm canyon and examined all of the bare 

 fallen trunks of which I had noted several in my previous search. It is 

 not an easy matter to chop into one of these palm trunks even when they 

 have been dead for years, but I worked two days at it without success 

 and was about to despair when a stroke of my axe turned out a larva 

 about three-fourths of an inch in length which I thought might be that of 

 Dinapate. By placing my ear against the log and keeping very still I 

 could hear others gnawing away inside with a click like that procbiced 

 by snapping the nails of the thumb and first finger together. However, 

 it was clear that if this was the larva of Dinapate it must grow at least 

 a year before it would be as large as that described by Horn, so I decided 

 to wait until the following spring before carrying out the plan which I 

 had in mind. 



"This last spring (1917), I again went to Palm canyon, sawed out 

 of the prostrate trunlv four two and a half foot lengths, taking them 

 where the gnawing sounded most frequent, and packed them out to my 

 automobile, a distance of aljout two miles. Another section of this log 

 was later obtained by Mr. J. R. Campbell of the U. S. Bureau of Ento- 

 mology. A week's further search of the various groups of palms failed 

 to show any other possible host tree. In sawing the log into transportable 

 lengths the saw disclosed several larvae in the various cuts, two of whicii 

 it bisected. The ones which were uncovered but not cut soon l^ored their 

 way into the log and out of sight. However, I was much surprised to 

 find that there were evidently two separate broods of larvae in tlie log, 

 one apjiarently full grown and ready to pupate as shown by the presence 

 of one pupa, tlie others about three-fourths of an inch long. I am con- 

 vinced that the larvae seen last year are the ones full grown and the 

 smaller specimens represent a brood deposited since the discovery of the 

 log. 



"Ihis log when discovered was full of sap and showed every evidence 

 of having been torn up by the winter flood which this year was the 

 heaviest in over forty years. There were no leaves attached and its size 

 showed it to be one of the older trees, the leaves of which were burned 

 off by the Indians. 



"On getting my ten feet of log iiome I at once constructed two stout 

 cages for their reception and then came a long wait. Every morning on 

 arising since March, when the sections of the log were brought home, my 

 first duty has been to inspect the cages. Not until August third was there 

 any change and my long watch was rewarded by my first sight of a living 

 Dinapate. A fine pair, lady and gent, had emerged during the night and 

 were vainly trying to conceal their huge bulks ostrich-wise by shoving their 

 heads into any dark corner. Since then until the present date, September 

 17, thirty-one of these beetles have emerged, generally one at a time, but 

 one morning there were four and several times two came together. At 

 first the sexes were quite evenly represented, but during the last two 

 weeks only females have emerged. 



"All of tliese emergencies took place after dark, in the early part of 

 the night, not later than 9 p. m. Several times I tried to see the beetles 

 come out by the aid of a lantern, but the presence of a light caused
