Some Observations on the Leaf-Hopper Wasp, Nesomimesa 



Hawaiiensis Perkins, at Pahala, Hawaii, 



Feb. 11-April 25, 1918. 



BY F, X. WILLIAMS. 



This is a slender, glossy black wasp (Fig. 1) about 1/2" 

 (13 mm.) long frequently observed slowly flying in the more 

 upland cane fields of the Hawaiian Agricultural Co. at Pa- 

 hala. N"one was seen below an elevation of about 1,000 feet, 

 and it was found to occur up to 3,500 feet; it was most plenti- 

 ful, however, in Wood Valley, altitude 1,850-2.200 feet, where 

 its adopted prey, the cane leafhopper {Perhinsiella sacchari- 

 eida Kirkaldy) was for some months very abundant.

Dr. Perkins has observed the Hawaiian Mimesidae storing 

 their burrows with native daddy-longleg flies (Limnobiidae), 

 but it is certain that some 'attack native leaf hoppers as well.
