Hah. In New Zealand, on Fagiis menziesii. My speci- 

 mens were sent by Mr. Eaithby, from Eeefton. 



This handsome form may be easily mistaken for a Coccid. 

 It is typical of the family in this respect : that the pupa is dis- 

 tinguishable from the larva principally by size and the larger 

 quantity of waxy matter.

Eggs yellowish-brown, elliptical ; length about xfo^^^- ' 

 peduncle rather short. 



Larva yellow ; somewhat thick, fiattish, regularly ellip- 

 tical ; length about -s^in. Dorsum bearing four longish fine 

 hairs, of which two are on the cephalic region and two close 

 to the vasiform orifice. Margin entire, not thickened, bearing 

 a row of rather long, strong hairs, sixteen on each side, and 

 two shorter ones at the abdominal extremity. Eudimentary 

 eyes dark-red, tubercular, may be made out. Vasiform ori- 

 fice broad, short, subelliptical ; operculum short, transversely 

 divided ; lingula obsolete. 



Pupa-case yellow ; elliptical; length about -0^1^- The dor- 

 sal four hairs as in the larva, and there is usually a small 

 quantity of dorsal white meal. Abdominal segments indis- 

 tinct. Margin with wide, shallow crenulations ; marginal 

 hairs as in the larva. Vasiform orifice, operculum, and lin- 

 gula as in the larva. On turning over the pupa-case the rudi- 

 mentary feet, antennae, &c., are clearly visible. 



Adult of general normal form ; length of body about ^^in. 

 Head and thorax dark-yellow. Abdomen lighter yellow. Geni- 

 talia brown. Wings narrow, grey ; nervure straight ; the basal 

 branch very short, almost obsolete ; margins of wings minutely 

 serratulate, each serration bearing a minute spine ; on the 

 anterior edge of the hind-wing are four very fine hairs. The 

 fore-wing bears four faint brownish patches difficult to dis- 

 tinguish ; they form almost two transverse bands, but do not 

 seem to meet at the nervure. Genitalia of male and female 

 normal ; each arm of the forceps of the male beai'S a few short 

 hairs. 



Hah. In Fiji, on a gramineous plant unknown to me. My 

 specimens were sent by Mr. E. L. Holmes. 



This species may be distinguished by the marginal and 

 dorsal hairs of the larva and pupa. Something similar may 

 be seen in A. citri, Eiley and Howard, as figured in Insect 

 Life, 1893, p. 219 ; but that species has four cephalic and 

 four posterior long dorsal hairs ; its wings are innuaculate, 

 and the adult male bears remarkable tufts of wax on the
