1I.—THE NOTODONTINA. 45 



two-thirds towards the apex ; there is a curved transverse series of black dots at about two-thirds, 

 and several obscure brown marks on the termen near the middle and at the tornus. The 

 hind-wings have several irregular rows of conspicuous Unci; spots. The cilia are cream-coloured 

 barred with black. Tbe apex of the fore-wing is very much rounded. 



The perfect insect appears in December, and is attracted by light. 



Described and figured from a specimen kindly given to me by Mr. Cohen. 



CHLOBOCLYSTIS EECTILINEATA, n. sp. 

 Plate VI., fig. 22.) 



This species was discovered at Wellington by Mr. W. P. Cohen. 



The expansion of the wings is | inch. The fore-wings are pale grey ; there are several irregular 

 black, transverse lines near the base, very broad mi the costa ; a broad, pale, central area with no 

 distinct markings; t/im two very fine, almost straight, parallel, dark transverse lines alternating with 

 two broader white lines, and followed by a very conspicuous black line, tins being again immediately 

 followed by a fainter black line; beyond these lines the wing is darker, with a wavy transverse 

 white line and a row of black terminal marks. The hind-wings are grey with several faint, 

 wavy, transverse lines and a series of darker marks on the termen. The cilia of all the wings are 

 grey.

Genus 4.— PHBISSOGONUS, Butl. 



"Face' with short cone of scales or smooth. Palpi moderate or short, porrected, more or less 

 rough-scaled. Antennae in male ciliated or naked. Posterior tibiae with all spurs present. Pore- 

 wings in male with swelling or tuft or rough scales on costa, vein 5 sometimes distorted or absent; 

 areole simple, 11 running into 12. Hind-wings with vein 8 anastomosing with cell from near base to 

 beyond middle." — (Meyrick.) 



^Ye have one species in New Zealand. 



PHRISSOGOXFS DENOTATUS, Walk. 

 (Scotosia denotata, Walk. 1361. Phibalapteryx parvulata, ib. 1721. Phrixogonus denotatiis, Meyr., 



Trans. N. Z. Inst. xx. 53.) 

 (Plate VI., fig. 19 J .) 



This dull-looking insect is common and generally distributed throughout the country. 



The expansion of the wings is \ inch. The fore-ioings are very dark grey, with numerous 

 obscure black and pale brown transverse lines; there are several black dots on the veins, and a 

 white mark on the termen near the apex. The hind-wings are pale grey with numerous wavy 

 black lines, especially near the dorsum. The antennm arc simple in both sexes. The cilia are dull 

 pink barred with black. The female is slightly tinged with reddish-brown. The male has a peculiar 

 dilation on the costa, beyond the middle, beneath which is a naked longitudinal mark occupying the 

 sjyaee between reins 10 and 12, these veins being sliijlithj distorted in consequence. 



Tbe larva, which feeds on the blossoms of the wbarangi (Brachyglottis rejpanda), 

 is pale green with a, series of elongate triangular brown markings down the back and 

 an obscure series of brown marks on each side. It may be found during the latter 

 end of October and beginning of November, but is extremely inconspicuous amongst 

 its food-plant. The pupa is concealed in a light cocoon constructed of tbe remains 

 of the blossoms. 



Tbe perfect insect appears from October till February. It frequents dense under- 

 growth in the forest, and is generally found resting with extended wings on tbe 

 dark-coloured stems of the kawakawa (Piper excelsum), where it is practically invisible. 

 In this situation its colouring is evidently specially adapted for protective purposes.
