PARLATORIA PROTEUS. 141 



narrowest, but both extremities are sometimes atten- 

 uated; when overcrowded they are frequently pyri- 

 form, and the character of the puparium is often 

 altered by contact with the venation of the leaf. 

 Colour pale greenish yellow, subdorsal area often 

 bright orange-yellow, margins paler ; and being trans- 

 parent the underlying ova, effete skins, and tissues of 

 the leaf give it a variety of local colours depending 

 upon the nature and contents of the puparium. Ex- 

 uviae at the cephalic extremity; those of the larva 

 usually project slightly beyond the margin ; are yellow 

 and covered with a thin transparent secretion ; second 

 exuviae occupying a little more than one third of the 

 entire puparium, are broadly ovate or almost circular, 

 and vary from greenish yellow to orange-brown; the 

 transparent secretionary covering frequently forms a 

 central and marginal carina. Cabinet specimens be- 

 come opaque, and are dull ochreous or of a dirty straw 

 colour. 



Long. 11-90 mm. Wide -25 '90. 



Adult female (PL XXX, fig. 11) approximately 

 circular, widest at abdominal segments. Colour varia- 

 ble, but usually of a pale translucent mauve or purple. 

 Cephalic segment with a minute spine at the margin 

 near the articulation. Rudimentary antennae with a 

 short spine. Rostral filaments extending slightly 

 beyond the middle. Margins of four free abdominal 

 segments, with numerous short tubular spinnerets. 

 Pygidium (PL XXXIII, fig. 2) short, but very broad ; 

 has four groups of circumgenital glands ; the formula 

 of five examples are given below : 



76 . 66 . 77 . 76 . 65 

 4__5 . 4_5 . 4_5 . 55 . 4-5 



Dorsal tubular spinnerets short, and very broad. 

 Vaginal opening opposite space between circumgenital 

 glands. Anal opening just below the posterior groups. 

 Margin of pygidiurn (PL XXXII, fig. 4) strongly crenu- 

 lated. There are three pairs of well-developed lobes
