Type in the collection of the Hawaiian Sugar Planters' 

 Experiment Station. Type No. 1028. 



Described from a single female. Probably a local race. 



Elytrurus bicolor sp. n. 



Female. Color black, the upper sides of the prothorax and elytra 

 clothed with green scales, with some buff ones intermixed ; the remainder 

 of the insect, including the scutellum, covered with dark buff scales, 

 those on the head, rostrum, legs mostly having a coppery reflection. 



Very similar structurally to E. samoensis, the description of which 

 will apply to it, except in the following points: Scales on the upper 

 surface larger and more nearly circular"; the longitudinal impression on 

 the pronotum much narrower, forming a more definite furrow and without 

 any central carina, the granules flatter and more confluent ; the sub- 

 lateral ridge on the elytra distinctly sharper, the granules on the disk 

 more conspicuous and forming more or less regular rows, and the setae 

 on the extreme margin of the apical half noticeably longer; the intercoxal 

 process of the mesosternun) very deeply emarginate at apex (in samoensis 

 it is almost straight or very slightly sinuate) ; the venter and the middle 

 of the metasternum with narrow lanceolate scales, those on the former 

 becoming gradually narrower posteriorly, so that on the last segment they 

 are almost hair-like; the front tibiae rather more strongly curved and 

 with longer denticulations. Length, 14.25 mm.; breadth, 7 mm.

Elytrurus bivittatus sp. n. 



Male. Color black, with markings formed of brill'ant pale green 

 scales, the pronotum shiny, the head and elytra dull; the head with a 

 large green spot just behind each eye; the prothorax with a broad green 

 median stripe from base to apex, and a small green spot in the middle of 

 the area on each side of it, the whole of the pleurae being densely 

 clothed with golden scales, which are mingled with green ones along the 

 upper edge; the scutellum with green scaling; each elytron with a single 

 very broad stripe from the shoulder to the apex, lying mainly between 

 striae 4 and 8; the lower surface densely clothed with narrow golden 

 scales, except the base of the mesosternum and the portions of the metas- 

 ternum lying between the mid and hind coxae, Avhich are bare. 



Head very finely and sparsely punctate, each puncture containing a 

 ?hort recumbent seta; the rostral costae encroaching somewhat on the 

 forehead, which bears a deep central fovea. Bostrum strongly dilated 

 from base to apex, the sides straight ; the dorsal area aciculate, with fine 

 sparse shallow punctures and slight inequalities, a very indefinite median 

 costa, and a more shiny and sparsely punctate lateral costa on each side
