The following additional material of this species has heen 

 collected : 23 females, 46 males )n Eragrostis variabilis-, ridse 

 west of Kalihi Valley (al)out lOOO ft.), Oahn. dime 1.'). 1919 

 (Bridwell and Timherlake), nearly onedialf of the s])ecimens 

 havins; heen reared from the niealyl)nii", Trioiiijiiias insiiJaris 

 Ehrhorn, June lT-'30, one to three issnina; from a host; and 

 4 females, 11 males on Eragrostis rariaJjilis. ]\ranoa Kidge, 

 Oahn, June 1, 1919 (J. C. Bridwell). 



The Kalihi specimens arc nearly identical witli the types from 

 Nuuanu Pali, but the coloration of the females is somewhat paler and 

 without the trace of lawny whicli may ha\'e been due to discoloration in 

 the types. In I')oth series tlie color is more ochraceous orange ( R. ) 

 than yellow ocher. The first funicle joint varies considerably in the 

 amount of yellowisji coloration and in one female is entirely black ; the 

 base of the abdomen is likewise variable, some specimens having the 

 first tergite entirely pale but in one female it is entirely black. In 

 the males the coloration is about orange rufous to flame scarlet (R. ). 



The Manoa specimens are distinguished by a fine reticulation on the 

 head of the female and I)y a considerably greater number of dark- 

 colored, minute, bristle-like hairs on the mesoscutum. but the coloration 

 is practically as in the Kalihi specimens. 



In the original description, p. 202. line 4, the following correction 

 should be made, for "the latter" read "occipital margin." The ovipositor 

 in this anfl probably in all tlie Hawaiian species is liidden in repose, 

 but in most mounted specimens tlie abdomen is more os less distorted, 

 somewhat in the manner assumed during oviposition so that the ovi- 

 positor and sheaths are shortly protruded. The latter .'ire flat and 

 laminate, broader at base and tapering to a blunt jxiint. The alxlomen 

 of the male usually remains oval-.shaped after drying or not flattening 

 out wider than the thorax and becoming rotund as in the allotype 

 sjiecinien.
