the larva were a pure white, following this moult. On the I8II1. it 

 was noted that the mouth parts had changed to a yellow, and tlu! 

 following day they had assumed their brownish black hue. Late 

 on the 19th, burrowing had recommenced. 



The pupal chamber is made parallel to the bark, and is entirely 

 free of sawdust. From this chamber the beetles cut a round hole 

 for emergence at right angles to the long axis of the chamber. 

 They emerge at night, and are thereafter nocturnal in their habits. 



When the final skin is cast, and the pupa emerges, this cast-off 

 garment remains as a rumpled pedicle, loosely adherent to the 

 caudel segment. 



I present on Plate A several drawings of the larva of this 

 beetle, made from live specimens. On Plate B are also shown three 

 aspects of the pupa. The latter are presented in sufficient detail 

 to obviate the necessity of a technical description. Figure II on 

 this plate is foreshortened one abdominal segToent. With this ex- 

 ception the drawings are in proper proportion and accurate as to 

 structure and detail. 



The species has been recorded, thus far, only from Palm canyon, 

 San Andreas canyon and Murray canyon, which are all a few 

 miles from the town of Palm Springs, in the Coachella Vallej", Cali- 

 fornia. It is rather strange that this beetle has not gained a foot- 

 hold in our Southern California towns and cities where the fan- 

 palm is much in evidence. Perhaps a careful search by horticultur- 

 ists for the round exit holes may disclose its presence.
