The female differs from immaturus in its more dusky color and 
much shorter antennae and from globosicornis in its more yel- 
lowish color and in having the funicle joints much less monili- 
form. The fore-wings in both sexes have a median discal row 
of six to eight strong setae on the apical half. 
136. Leimacis peregrina Perkins. 
Described in 1910 from specimens taken in Honolulu. I have 
not seen this species. 
137. Gonatocerus mexicanus Perkins. 
Recorded by Mr. Swezey in 1916 from specimens reared 
from the eges of Draeculacephala mollipes (Say) collected at 
Kapiolani Park, Honolulu, on August 26 and 27, 1915; one 
female was taken by Mr. Swezey on sugar-cane in Honolulu on 
October 14, 1914. 
138. Gonatocerine. 
One female taken by Mr. Swezey on a window in Honolulu 
on November 28, 1915, has the antennae very long, slender and 
ten-jointed. The fore-wing is clavate, with a long fringe only 
at the apex and with about three irregular rows of discal setae 
on one surface and two submarginal rows on the other surface, 
each row being composed of about six setae and confined to 
the broadened apical part of the wing. The specimen is only 
0.24 mm. long and has the antennae, legs, and wings consider- 
ably longer than the body. Another specimen was taken by me 
in the entomological laboratory of the Sugar Planters’ Station 
on March 25, 1924. 
139. *Anagrus frequens Perkins. 
Introduced in 1904 from Queensland and now common and 
widely distributed in the Islands. It attacks the eggs of other 
Delphacids besides Perkinsiella, and has been reared from the 
eges of Peregrinus maidis (Ashm.), Sogata paludum (Kirk.), 
Kelisia sporobolicola WKirk., and Liburmia leahi (Wirk.). This 
species has been synonymized with A. armatus (Ashmead) by 
Mr. Girault, and perhaps correctly so, although I prefer to use 
the name frequens at present. 

* Purposely introduced insects are starred throughout the list.
