LÉPIDOPTÉROLOGIE COMPARÉE 409 



Head. The head is markedly narrower than the thorax. In 

 colour, it is purple just as in hirtarïa and the spotting resembles 

 hirtaria too, for it is not so evenly distributed nor so dot-like as 

 in ponionaria. Its shape is that of pUzii. The mouth parts are 

 dull yellow, blackish edged. The antennae are yellovvish at the 

 base and the club is somewhat purple. fhe head can be protruded 

 slightly from the thorax. 



Body. The ground colour of the body is a dull purple or a 

 dirty plum but it varies from pale yellow to thèse colours. 



The two medio dorsal stripes are not continuous; they tend 

 to be broken at the anterior trapézoïdal tubercles; many of the 

 specnnens show, by a washed out attempc at the edging, an attempt 

 to combine the break in hirtana with the continuity of fomonaria. 

 In shape they are broad after a bar, and taper up to the break, 

 and then after an mterval of broadening, continue parallel edged 

 up to tne next bar. Thèse stripes are slightly better marked than 

 in hirtaria on the thorax and toward the end of the abdomen, but 

 are otherwise very much the same as in that larva. On the whole, 

 they are more parallel edged than in fomonaria. 



The subdorsal stripe is broader than the mediodorsal one, 

 except on the last subsegments. While the âlling in of ail the 

 stripes is brick coloured, it is bnghter in this line. The stripe 

 tends to break at the same points as the other ones, but the edging 

 remains although m a weakened condition. 



The supraspiracular stripe too, is présent and is f airly even ; it 

 seems to be divided into detached parts. 



The collar resembles that of hirtaria although not so bright in 

 colour. 



The mediodorsal area is very often grey or slate coloured. 



Whilst the yellow bars are présent, they show a strong tendency 

 to be reduced, but they are always better marked than in hirtaria, 

 in which they may be obsolète or very small. 



In many examples of hiinii, thèse bars may be developed to a 

 varying extent on the 6th and /th abdominal segments. On
