ength, 3:5 mm.; tegmen, 4mm.. “ Pale ochreous-brown. Head 
(except the keels of mus vertex, side of the frons and antennae), scutellum 
(except the side margins), apex of tarsi and abdomen (except genitalia) 
more or less piceous or piceous-black" (Buchanan White) To this ma 
be added the following description of genitalia: Pale-brownish. Medio- 
ventral projection of pygophor prominent but wide and rounded. Genital 
styles with very short stalks and long blades with broad roundish base 
and narrower apex. Aedeagus straight and almost unarmed. 
Leng mm.; tegmen, 4:5 mm. Colour slightly paler. Ovipositor 
brownish, stout, but sharply pointed. Normally a heavy mass of waxy 
material between anal segment and ovipositor. 
Twenty-five males and thirty-five females. Mount Egmont (Miss J. 
on); Tararua Ranges, 3,300-3,600 ft. (J. С. Myers); Mount Arthur 
(T. Cockcroft); Arthur’s Pass, 2,600-2,800 ft. (I. Н. and J. G. Myers) ; 
Wakatipu, 3,600ft. (G. V. Hudson). Hutton gives the range as ** Otago." 
This short squat species is apparently confined to the subalpine scrub 
and to the undergrowth of the forest at its upper limit, in which places it 
often occurs in vast numbers. The South bes specimens have tegmina 
slightly more variegated—some of the v eing more conspicuously 
picked out in whitish than in the North Island specimens—but this differ- 
ence is not constant. 
Genus 4. HUTTIA nov. 
Type: Н. nigrifrons n. sp. 
Body short and squat. Tegmina long and hyaline. Vertex = a 
median longitudinal ridge. Face with no median longitudina 
Pronotum very narrow, flattish, ы уч a median longitudinal keel d is two 
lateral ones, none very prominent. Mesonotum rounded, with five keels. 
Hind tibiae spined. Tegmina long, narrow and parallel-sided. Sc and R 
joined for rather less than one-third; their bases joined to M for about 
one-eighth of clavus. Cu forked about middle of clavus; claval veins 
margin near apex, forked about middle. A cross-vein from first 
claval to Cu, at about one-fifth along clavus. 
Huttia nigrifrons n. sp. (Plate 22, fig. 7.) 
Ф. Length, 5mm.; tegmen, 6-5 mm. Olivaceous marked with blackish. 
urv 
tinct, the keels olivaceous and intervening spaces blackish. Tegmin 
glassy-clear, including the veins, except where the latter, at intervals, are 
marked with black. A few fuscous marks along the inner border of clavus. 
Abdomen rounded. Anal segment and ovipositor almost same length,
