Report ami Yearbook of the Experiment Station Committee of the 

 Hawaiian Sugar Planters' Association for the year ending Septem- 

 ber 30, 1905. Honolulu, 1905. 



This report appears to be from a committee of the experiment 

 station in the planters' association, though no author is mentioned. 

 A list of all the officers is given on the first page. There are a number 

 of separately paged papers, of which only the entomological ones in- 

 terest us here. These are Bulletin no. 1 — Leaf-hoppers and Their 

 Natural Enemies, divided into parts : 



Part I — Dryinidai, by R. C. L. Perkins. 



Part II — Epipyropidse, by R. C. L. Perkins. 



Part III — Stylopidse, by R. C. L. Perkins. 



Part IV — Pipunculida?, by R. C. L. Perkins. 



Part V — Forficulidas, Syrphidse and Hemerobiidae, by F. W. 

 Terry. 



Part VI — Mymaridse, Platygasteridae; by R. C. L. Perkins. 



Also two circulars by Perkins on the history and occurrence of the 

 sugar cane leaf- hopper {Perkinsiella saccharicida Kirkaldy) and some 

 diseases of cane especially considered is relation to the leap-hopper 

 pest and to the stripping of cane. 



The part on Lepidoptera treats of the family Epipyropidse, which 

 Mr. Perkins proposes as new, but which we had already used (Bull. 

 52, U. S. Nat. Mus., 359,. 1903). Three new genera and seven 

 species are described (from Australia), and many new and highly in- 

 teresting facts about the life histories and habits are recorded. Perhaps 

 the most peculiar are that some of the species are parthenogenetic, 

 while the newly hatched larva has a special structure and actively 

 seeks its prey, the eggs being laid on plants. The larvae seem to be 

 true parasites, causing the death of the host. Mr. Perkins gives a 

 synoptic table of the genera, but does not include the genus Epipyrops 

 of Westwood, which we would do as follows. We would add a new 

 genus, Epipomponia, proposed for our species nawai (Proc. ent. soc. 

 Wash., vi, 19, 1904) described from Japan. In the bibliography 

 Mr. Perkins could have added two notes published in the Proc. ent. 

 soc. AVash., v, 180, 1903, and vi, 19, 1904.
