Coloration of head, thorax, scape and pedicel about xanthine orange 

 (R.), the legs concolorous with the front coxae and all the tarsi 

 paler; flagellum of the antennae and the alidonicn piceous or lilack. 



Described from 15 females, 12 males (type, alloty])e and 

 paratypes) collected on Eragrostis variahUis on the soutli wall 

 of Palolo Valley, Oalui, May 30, 1919 (J. C. ]^>ridwell), and 

 1 female, 1 male (paratypes) on the same grass at Koko Head, 

 Oahn, 25 ft. elevation. Dee. 15, 1918 (Giffard and Muir).

The following additional material of this species has Ix'cn 

 collected : 23 females, 46 males >n Eragrostis varkihiUs, ridge 

 west of Kalihi Valley (ahont 1000 ft.), Oahn, Jnne 15, 1919 

 (Bridwell and Timberlake), nearly one-half of the specimens 

 having been reared from the mealybng, Trionymus iiisularls 

 Ehrhorn, Jnne 17-30, one to three issning from a host ; and 

 4 females, 11 males on Eragrostis variabilis, Manoa Ridge, 

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



The Kalihi specimens are nearly identical with the types from 

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

 without the trace of tawny which may have been due to discoloration in 

 the types. In both series the color is more ochraceous orange (R.) 

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

 amount of yellowish 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 CR.). 



The Manoa specimens are distinguished by a fine reticulation on the 

 head of the female and by 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 he made, for "the latter" read "occipital margin." The ovipositor 

 in this and probably in all the Hawaiian species is hidden in repose, 

 but in most mounted specimens the 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 are flat and 

 laminate, broader at base and tapering to a blunt point. The abdomen 

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

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

 specimen.
