same area. An occasional specimen with well- 
developed red markings has also heavily in- 
fuscated pronotal shoulders.

from low ferns at Paihia, Bay of Islands, 
North Auckland, February 13, 1949; 22 males, 
18 females, 29 nymphs, swept from low ferns

Wales (Macleay Collection). One female, 
Brisbane, June 3, 1932; 2 females, 1 male 
(no data, but almost certainly from neigh- 
bourhood of Brisbane); Dept, of Entomology

F. elegantulus was described from Victoria, 
Australia. The present records considerably 
extend its known distribution, north to New 
South Wales and Queensland and east to both 
the North and the South Islands of New

STRUCTURE: Head width across eyes nearly 
1.5 times the length (17.5:12); interocular 
space nearly twice as wide as eye (8.5:4. 5). 
Basal 0.17 of head cylindrical, forming a col- 
lum separated from rest of head by a sharp 
annular constriction, in front of which the 
crown is moderately raised and convex; from 
constriction, sides convexly diverging to pos- 
terior margins of eyes, where head is rather 
less than 0.75 as wide as across eyes (12:17.5); 
basal collum about 0.83 the width of head 
at base of eyes (10:12) and over 0.5 the width 
across eyes (10:17.5). Rostrum reaching to 
middle coxae. Antennae with segment I cy- 
lindrical, with long, erect, sparse hairs; II 
more slender than I, pubescent; III and IV 
very slender, curved; length of I:II::28:35. 
Pronotum in median line over 1.5 times 
length of head (21:12); about 0.25 wider across 
posterior angles than long (26:21), about 2.3 
times as wide as across anterior collar (26:11), 
and 1.5 times as wide as head across eyes 
(26:17.5) ; in mid-line, anterior lobe, including 
collar, shorter than posterior lobe (9.5:11.5), 
the constriction between them coarsely and 
deeply punctate toward sides, with the two 
middle punctures set well forward; posterior 
lobe strongly raised from constriction; both 
lobes evenly convex from side to side except 
for sublateral depressions inside posterior 
shoulders; shoulders with lateral margins 
nearly straight, sides of pronotum sinuate in 
front of them; base distinctly and roundly
