FIJI-NEW ZEALAND EXPEDITION 137 
A small elongate, blackish lygeid (Pamera sp.) is not uncom- 
mon; another small grayish member of this family (Germalus 
pacificus) with a rotund thorax and reddish eyes occurs frequent- 
ly. 
On June 21 at Makuluva I found on a mula-mula tree and on 
the dried leaves beneath it a strikingly colored yellow and black 
pyrrhocorid (Dysdercus msularis) in all stages of development. 
Hundreds of the insects could have been taken in a very short 
time. Although the species is found on Vitilevu I never saw it 
again in such numbers. 
Of the shield-backed bugs (Pentatomoidea) the shining black 
coptosomid (Brachyplatys pacificus) is the most common being 
found in greatest numbers on yellow hibiscus although it also fre- 
quents lantana, mile-a-minute, cyrtospermum and other plants. 
The most striking member of this group is the highly colored, 
obese, exceedingly variable and sexually dimorphic form, Tecto- 
coris lineola, which occurs most frequently on mula-mula trees 
growing, usually, near the beaches. On June 20 all stages were 
taken at Nukulau and Makuluva though young were more abund- 
ant than adults. Often, clusters of from five or six to fifteen or 
twenty of the metallic green and black nymphs clung to a tender 
twig from which they were extracting the juice. The broadly 
convex scutellum of the adult female is usually yellowish with 
four large irregular dark areas; the scutellum of the adult male 
is iridescent purplish with four blackish crescents. The species is 
recorded as an enemy of the larve of the coconut moth (Levuana 
iridescens) . 
Near Tamavua, I took, on a slender, smooth-barked tree with 
green and red berries, many nymphs and a number of adults of 
the trim-appearing and brightly colored scutellerid, Lamprophara 
bifasciata. The coloration of the bugs blended in so well with the 
fruit that they were exceedingly difficult to distinguish. In all, 
something like ten species of Pentatomoidea were taken on Viti- 
Jevu. 
On several ponds and small streams about Vitilevu I took 
water-striders (Hydrobatide) and in a tide-pool at Makuluva I 
found a small marine form. 
Of the Homoptera, the cicadellids or leafhoppers abound in 
some numbers in grassy situations, along woods and in fields. A
