sand and a Comstock A-ial used in the opening.', to collect the para- 

 sites which cc:)me to the light. The fern pots are sunk in moist soil 

 to keep the buds from drying out. 



]\Ir. Chittenden reports four parasites for this insect, none of 

 which was reared from this locality. 



Several buds were placed in the breeding-jar on July 5. A 

 total of 419 weevils was reared and 184 parasites, giving- a total 

 of 31.3 per cent parasitism. Two are new species, as reported by 

 Mr. Girault, as follows : 

 Chalcidoidea : 



Eiipchnus colcopteroph.ai^iis N. sp. 5 ? 's. 

 Catolaccns pcrdiibins X. sp. 62 $ 's and 45 9 's. 

 Hahrocytus obsciiripes Ash. 11 ? 's and 28 S 's. 

 Polyncma coiisobrinus (iirault 1 c^ and 3 9 's. 

 Eiirytoma sp. 1 mutilated 9 . 

 One small encyrtid. 

 A few Proctotrypidae. 



CECIDOMYinAE : 



Lcstodiplosis sp. 14. 



Alidge larvae were occasionally found within the buds, July 11, 

 1916. The adults are a species of Lestodiplosis, as determined by 

 E. P. Felt. Members of this genus are predaceous and possil^ly 

 scavengers. 



Lcstodiplosis sp. — Lan'a. — l.S mm. to I.Cf mm. long; orange- 

 red ; somewhat flattened and tapering toward head end. The mouth 

 parts are prominent. Ventral surface of each abdominal segment 

 covered with small tubercles and with two hairs projecting from 

 each. 



A small black dipteron was also reared from the buds and 

 named by Aldrich as Elachiptcra cosfata Loew. 



Out of 162 buds examined July 1, 

 56 contained nothing, 

 61 contained weevil larvae, 

 46 contained parasites, 

 giving 43 per cent parasitism of the buds which contained larvae. 

 Parasitic larvae were not numerous until June 20, while on July 8, 

 being about the end of the picking season, the adult parasites were 

 emerging in large numbers from the insectary pots. Some emerged 

 even on July 25. In a few instances hyperparasitism was observed. 

 Ordinarily, when a bud is opened, the larva strikes violently back 

 and forth. If, however, it is parasitized, it will remain motionless,
