this moth reared from a caterpillar collected on Maha sa)id- 

 iciccusis in W^aialae Iki \'alle>-, March 21. 1920. 



Sfcr)iocliactiis )iiani:!:ifcrae. — ^Ir. Swezey reported finding 

 mango seeds in Hilo infested by the mango weevil and that 

 Bro. ^Matthias told him that he had known of this weevil there 

 for several years. 



Teratitra sp. — Mr. Swezey reported that this new Locustid 

 immigrant at Hilo, Hawaii, was apparently on the increase. 

 Several specimens could be secured any evening at the Hilo 

 Hotel, where they came to lights. All specimens were females, 

 however, and it was not possible to find a male. P.rother ^lat- 

 thias is having the same experience with this insect. 



Monocrcpidiiis exsvd. — Mr. Swezey reported an investiga- 

 tion of the damage to sugar cane by wireworms at Honokaa, 

 Hawaii, in which it was found that the wireworms were the 

 Iar\ae of this Elaterid. which has hitherto been considered 

 predaceous. They were found in cane fields eating out the 

 eyes of recently planted seed cane. This was in an area of 

 several hundred acres and would necessitate niuch replanting. 



The investigation brought out the presence of larvae of the 

 Olinda beetle (Pantomorus fnllcrl) in most of the fields, and 

 it is likely that their presence was the primary cause of the 

 presence of the wireworms. lioth larvae were found generally 

 distributed in the plantation, occurring in cane stools of fields 

 being plowed ; in the stubbles of fields recently harvested ; in 

 standing cane about a year old. as well as in the recently 

 planted fields. 



Specimens of the other wireworm, Siniodaciylus ciiiiia)no- 

 iiieits, were scarce in the fields investigated. 



Tachinid parasite of Cori.ciis. — Mr. Swezey exhibited a small 

 tachinid fiv reared from an adult bug of Coricits liyalimis. Six 

 of these bugs were collected on Sonchits at Puuloa. Oahu, on 

 March 24, 1920. A maggot issued from each of three of these 

 bugs, but only one produced a fly. This may be the imde- 

 termined tachinid that Dr. Perkins refers to in the Introduc- 

 tion of the Fauna Hawaiiensis. It has been collected by Mr. 

 Swezey at Naalehu. Plawaii. in 1905. and by Mr. Williams on 

 the Ewa Coral Plain in 1920.
