near the top. At Oranjie a Sinoxylon dccUve was found in its burrow 

 in a piece ot orange wood turned into a potato masher and left in tlie 

 turning hithe over night. The beetle had burrowed into this stick dur- 

 ing the night. 



Sinoxylon suturale. — Found several pupfe and a few recently trans- 

 formed beetles in their burrows in dead grape vines October 4. They 

 were mostly at the joints, usually two at each joint. In one of the bur- 

 rows I found a parasitic pupa not inclosed in a cocoon. The parasite 

 issued October 28. 



Amphiccrun imncUpenms. — On the 4tli of October 1 found two of these 

 beetles in a burrow in a dead and dry branch of a fig tree. March 26 

 I found three beetles, each in a burrow in a dead and dry grape cane. 

 They had evidently burrowed into the cane while in the beetle state, 

 since their heads were turned in an opposite direction fi'om the mouth 

 of the burrow. Two of the beetles were dead, but the third was still 

 alive. 



Psoa maculata. — Found many larvae in dry apple limbs October 9. 

 Several had entered the tips of the lateral short branches and extended 

 their burrows down the main branches, packing them with a sawdust- 

 like substance. October 11 1 found several larvae and one pupa in dead 

 and dry prunings of grapevines. 



On the 1st of January I found four beetles and eleven pup^e in a 

 rotten stem oi Audihcrtia polystacliya; the beetles had but recently es- 

 caped from the pup.ne and no larvte were found. By the 14th of Janu- 

 ary four beetles had issued. I captured a beetle of this species at Santa 

 Barbara April 11. 



Lyctus striatus. — Found several pupte in a dead grapevine October 4 ; 

 they were in their burrows between the joints. Two beetles issued 

 October 10, and three others were in their burrows October 22, 



October 28, 1888, I obtained several pieces of wood from a trunk of 

 an orange tree that had been cut down- about two years previously; at 

 that time there were numerous round holes in it about one-sixteenth of 

 an inch in diameter, and upon splitting it open I found a great many 

 burrows closely packed with the gnawed wood. I inclosed this wood 

 in a tin can, and one beetle was found June 1, 1889; the can was last 

 examined May 15. When next examined, June 19, three beetles were 

 found ; twelve were found July 20 and three July 20. 



March 21 I obtained several pieces of dead and dry sycamore wood 

 containing the burrows of wood-boring insects, and June 1 two living 

 and two dead beetles of this species were found. This box was last 

 examined May 15. 



Phymafodefijuf/lnndis. — These beetles were in their burrows in the sap- 

 wood just beneath the bark of a branch of Juylam calif ornica March 

 9. Some of them were still soft, having but recently issued from the 

 pupa state. In this same situation I found a pux)a and several legless 

 larvfe, e\idently of this species.
