Bridwell), taken in Iao Valley, 
7 
Flats, Oahu, in June, 1917 (Br 
Maui, on September 5, 1919 (Bryan). 
113. Tetrastichus sp. 
Collected at Makiki, Oahu, January 25, 1907 (Swezey), and 
now rather common in Honolulu. Most of my specimens were 
taken on store windows, although the species also occurs in the 
open. It is distinguished from other Hawaiian species by the 
median scutal groove, the dark femora and yellow scape and 
pedicel. 
114. Tetrastichus sp. 
Of this species I have seen only one specimen, collected by 
me from a store window at Kaimuki, Oahu, on January 5, 1918. 
It is somewhat similar to hagenowti, but is much more de- 
pressed, more metallic, and with a smoother sculpture. It seems 
to be closely allied to 7. metallifer Masi. 
115. Tetrastichus sp. 
Taken by Dr. Perkins at Kilauea, Hawaii, in June, 1906, and 
there is a note attached to the specimen to the effect that it was 
apparently associated with Eurytoma or a Pteromalid parasitic 
on Diptera, and that the species is widely distributed, as he had 
taken it on Tantalus, Oahu. Mr. Giffard has also reared this 
species at Kilauea from Tephritis puparia in Raillardia flower- 
heads, April, 22, 1920. Among Hawaiian species it is most 
similar to the third species recorded above (No. 113), but it 
has the propodeum much shorter, the oral margin yellow, the 
scape and pedicel dark, and the femora yellow at base and apex. 
ELACHERTINAE. 
116. Elachertus advena Timberlake. 
This species will be described elsewhere in the near future. 
First recorded by me in 1919 as Elachertus sp. from specimens 
reared by Professor Crawford in Honolulu from Hypothenemus, 
but taken as early as June 10, 1917, on Tantalus by Mr. Brid- 
well. Taken at Waikee, Maui, September 4, 1919 (Bryan), and 
a good series, including males, was taken by Mr. Fullaway on 
Sand and Eastern Islands, Midway, in April, 1923.
