wide as the prothoracic sej^iiK-nt, but not as wide as the body ; it 

 is full and rt)unded, though a Httle flattened above; it is deep pea- 

 green, but concolorous with the body ; on the vertex are four sliort, 

 faint whitisii Hues (sometimes wanting), the inner two i)arallel, the 

 outer somewhat diverging ; eacii side of the elypeus is lined with 

 whitish ; on the side of the head is a pink line edged above with 

 white and extending to the base of the antenni\i. 'I'he mandibles 

 are green at base with an orange-red line along the upper edge, 

 the tips being black. There is a short, bhuk line above at the 

 base of the antenniv. 



The bt)dv is noctuiform, tapering towards the anal legs, which 

 are short and small, no larger than the other abtloniinal legs. The 

 suranal plate is small, rounded at the end, not large and conspic- 

 uous as in JVaiiata i;i/>/>osa. The segments are not convex, but the 

 sutures are distinct. A double median, whitish, somewhat broken 

 line, sometimes faint, the two lines converging and forming a 

 single one in the middle of the suranal plate, and slightly tinged 

 with pink. A distinct lateral jiink line begins on the side of the 

 head and extends to the end of the body along the ii(\git of the 

 suranal plate ; the line is somewhat finely bordered with brown, 

 and is edged below with white. In one specimen along the sides 

 of the body are two broken yellowish-white lines, the lower of the 

 two more broken and yellowish than the ui:)per one, and represent- 

 ed by two spots on each segment; it lies midway between the 

 upper and the pink and yellow spiracular line. 



The whole body is pea-green, or sometimes suffused with a 

 roseate or pinkish tint ; it is slightly darker below than along the 

 back. The thoracic legs are greenish-amber, spotted externally 

 with black. The abdominal legs are green like the body. 



In some examples the lateral reddish spiracular line is not so 

 distinct, while the white lower <^i\\fc is nearly obsolete.
