29. Pachyneuron siphonophorae (Ashmead). 
Reared from Ephedrus incompletus Provancher in an Aula- 
corthum sp. on rose-bushes, Honolulu, April and May, 1914 
(Swezey), and from the same host at Wailuku, Maui, in June, 
1916 (Swezey). Reared also from Diaeretus chenopodiaphidis 
(Ashmead) in Myzus persicae (Sulzer) on cabbage, Palolo Val- 
ley, Oahu, in August, 1917 (Timberlake). 
30. Pachyneuron sp. 
Three females were reared from puparia of Leucopis nigri- 
cornis Egger collected on sugar-cane in Honolulu in August 
and September, 1919 (Osborn and Timberlake). Recorded by 
me in 1920 as P. anthomyiae Howard in Proc. Haw. Ent. Soc., 
4, p. 330, but it is very distinct from the common Leucopis 
parasite of the United States, which I believe is correctly 
identified as anthomyiae. The local species has practically no 
neck on the propodeum, and has the petiole of the abdomen 
smooth and polished and with a distinct prong on each side at 
about the middle. I have the same species also from California, 
where it was reared from several species of Coccidae. 
MISCOGASTERIDAE. 
31. Tomocera californica Howard. 
This species was an early immigrant to the Islands and was 
collected by Blackburn. It was described by Cameron under 
the name of Moranila testaceiceps, and has been found on 
Oahu, Maui, Molokai, Lanai and Hawaii. 
32. *Tomocera ceroplastis Perkins. 
Found by Dr. Perkins on Tantalus, Oahu, and described as 
a parasite of Ceroplastes rubens Maskell in 1906. I have reared 
what is apparently this species from Asterolecanium pustulans 
(Cockerell) at Honolulu. The species seems to me _ rather 
doubtfully distinct from californica. According to Dr. Perkins 
it was introduced by Koebele from China. 
* Purposely introduced insects are starred throughout the list.
