obsolète. The other stripes are indistinctly outlined, and are much 

 interrupted. Thèse stripes, except the medio-dorsal ones, are 

 much less developed than in hirtaria and ail are very indistinct 

 and confused on the last abdominal segments. 



The yellow collar is much more continuous than, and lacks the 

 beaded appearance of, that of hirtaria. The two well developed 

 tubercles, so well marked on the eighth abdominal segment of 

 hirtaria, together with their short bristles, are now quite conspi- 

 cuous but, in a few, they are just as in zonaria. 



The anal plate is marbled as in zonaria, but the colour is more 

 greyish than yellow. Nevertheless, it is yellow tipped and this 

 yellow is interrupted by four blackish tubercles provided with 

 setas. Sometimes the larger spots, always présent on this plate 

 in hirtaria, are quite distinct. The two yellow spots before the 

 plate are présent and are shaped like a fish tail. 



The spiracular stripe is broad and yellow, but the hirtaria yellow 

 spot is visible on it as a far brighter patch. It may even stand out 

 as orange surrounded by the primrose yellow of the stripe. The 

 stripe dips a little as it reaches the spiracles so that they 

 are above it, and are not enclosed in it, as in zonaria. In a few 

 of the spécimens, the stripe is reduced and, in addition, there are 

 présent the characteristic features of the spiracular line of hirtaria, 

 that is, just behind the spiracles, we hâve a yellow crescent shaped 

 spot, and beneath them a yellow dash. Thèse are more particu- 

 larly observable on the first abdominal segment and in spécimens 

 with a v/eakened spiracular line, may be suppressed elsewhere. The 

 spiracles are rather large and black and are situated in a suffusion 

 that may be continued along the spiracular stripe. The first 

 spiracle is the largest and is raised far above the common level 

 of the others. 



Ventrally, the colour is blackish with two rather indistirct 

 médian stnpes of the type seen in zonaria similar to those found 

 on the dorsal area. The prolegs, too, are blackish although some- 

 what paler anteriorly. The are very distinctly shorter than those 

 of hirtaria.
