Eleven Froterhinus [2 undetermined spccie^). 



Note: — It is interesting to note t'hat Pectinopliom rjossy- 

 piella attacks the seeds of Hihiscadelphus and is not coutiiicd 

 (as Mr. Bnsek has stated) to Gossypiuin. The Ilihiscacii'iplius 

 are indigenous but exceedingly rare in our native forests, and 

 ^vhilst a species of .so-called "red cotton" (Kokla liocl-ii ) is 

 sparsely distributed in the forests of one section of >>'()rtli 

 Kona, yet it is not the true cotton and Mr. Rock informs me 

 that on many visits to the region he has never noticed that 

 the "red cotton'' bolls were ever atacked by anythino- ap- 

 proaching Pectinopliora. Mr. Busck however records the fact 

 that Lefroy has bred it from Tiihiscus (an ally of Hihlxcadd- 

 pints) in India. 



It was also interesting to note that one can breed out of 

 the stalks and seed pods of Hibiscadelphus so many insects of 

 various Orders, although it may be taken for granted that 

 some of these are more particularly attached to other tref^* than 

 the particular one referred to. 



Froui the flower heads of Raillwrdia ciliolata collected at 

 Kilauea, October, 1917, a good series of the following insects 

 were bred : 



Diptera. — Tepliriiis sp., a good series of au uudertermincd 

 species. 



Homoptera. — Nesosydne raillardiae, one nyuipl;. 



Parasitic Hymenoptera. — Eight Phanwus vulcanus Perk. 

 This is probably parasitic on the eggs of a bug {Nusius s]).), as 

 Mr. Swezey in examining the flower heads foand several 

 empty bug eggs similar to Nysius eggs previously found by 

 him in the flower heads of Bidens. 



Two Eulophids (Teti-astichus sp.). These issued from 

 puparia of the Tcplirifis as ]\[r, Swezey found, on lalci- ex- 

 amination, two puparia having exit holes made by sonn^ ])ara- 

 site. Ml'. Tiud)Orlakc examined these Trfrds/ich ns sjicviuieus 

 and pronounced them as belonging to an underteruiined species. 

 It is apparently a native insect, and the first natiA-.- species of 

 the oenus to be recorded in the Hawaiian Tslauds.
