On a small lot of pods of Acacia farnesiana upon ^vliicb 

 the eggs of Caryohorus gonagra had been deposited in large 

 nnmbers. taken at Waialna, Oct. 4,1918, only about 50 per cent 

 of the eggs had been parasitized, leaving enough larvae of the 

 Bruchid to practically destroy the pods. The reason for this 

 smaller percentage was perhaps due to the fact that in this dis- 

 trict the only host plants for the Bruchid were Acacia farne- 

 siana and Prosopis juliflora and these ripen their seed in par- 

 ticular seasons, so that the species does not liave continuous 

 breeding places throughout the year and the parasite has a 

 correspondingly limited opportunity for multiplication. 



12. Credit Where Credit is Due 



The paper in last year's Proceedings, pp. 465-505, was 

 prepared for publication under the pressure of wartime duties 

 in connection with the Selective Service and in the haste of 

 finishing up, it was finally published without recognition of 

 the assistance given me in the preparation of the plant list by 

 Dr. H. L. Lyon, :\Ir. J. F. Rock and Mv. E. L. Caum. Thi^ 

 oversight was particularly regretable since unintentionally cer- 

 tain plants were there first recoi-ded as growing in the Hawaii- 

 an Islands. The identifications of all the weedy Cassias were 

 made by Mr. Rock. 



13. A COREECTIOX. 



In the discussion of the oviposition reflexes in the former 

 paper on Bruchidae, I had occasion to discuss the habits of a 

 South African Ichneumonid parasitizing SarcopJiaga. This 

 was referred to under the name of Allotypa sp. This is an 

 error. The insect is described elsewliere in this number of 

 these Proceedings as Atractodes mally\
