Polycaon confertus Lee. — Bred from larvae found in the Live Oak and 

 Almond. The beetles of both species of Polycaon have been observed 

 to bore burrows into living trees. 



Fsoa 4-signata Horn. — I have bred this species from the dry prun- 

 ings of the Grape-vine. Have observed the larvae and pupae in the 

 dead stubs on living vines. Beetles appear in March, flying about in 

 the vineyards during the heat of the day. 



Lyctns striatus Melsh. — Bred from the branches of Quercus agrifolia 

 and Q. duMosa. 



CUPESID^. 



Cupes lohiceps Lee. — Observed in all stages of development in the 

 decaying stumps of the Live Oak. 



Gis dlchrous Lee. — Bred from a species of lungTis which grows upon 

 the Live Oak. . 



CERAMBYCID^. 



Urgates spiculatus Lee. — Larvae obtained from the decaying roots of 

 coniferous trees. 



Frionns californicus Mots. — The larvae of this species live in the de 

 caying and rotten stumps and roots of the Live Oak. They never 

 attack the living or sound wood. The beetles are plentiful at evening 

 about groves, during July and August. 



Fhymatodes ohscuriis Lee. — I have bred this beetle from branches of 

 the Live Oak. 



(Erne gracilis Lee. — Bred from the dead wood of Quercus agrifolia at 

 Poway. 



MapMdion imhelle Lee. — Larvae of this species plentiful in the dead 

 wood of the Live Oak. The beetles are common beneath bark in Au- 

 gust. 



Megohrium edwardsii Lee. — Two beetles taken from beneath the bark 

 of the Live Oak ; one was just about to escape from its burrow. 



Xylotrechus nauticiis Mann. — Abundant about Live Oak groves dur- 

 ing the months of July and August. The larvae and pupae have been 

 taken from the dead branches and trunk of the Oak. The beetle is 

 both diurnal and nocturnal in its habits, becoming active near the mid- 

 dle of the afternoon, continuing so until late in the evening. This in- 

 sect is of considerable economic interest, being one of the few which- 

 commits serious damage to the wood of the Fticalyptus glohtilus in 

 the United States. Several years ago it was stated by the tree-growers 

 that Eucalypti were free from the ravages of pests, and that the wood 

 was valuable for wagon- work, posts, etc., which greatly increased the
