 longitudinal and two transverse ridges, the median ridge touching the margin in 

 front and terminating at the anal aperture, the anterior transverse ridge meeting 

 the margin between the stigmatic clefts, the posterior ridge extending to a point 

 about midway between the second stigmatic and the anal cleft. Flat below, with 

 abdominal cavities for reception of young larvK. Colour bright reddish yellow 

 to reddish brown, ridges and margin paler, a few irregular dark brown radiating 

 lines or chains of spots more or less distinct in different examples. The whole

 of insect. No definite dermal cells, but some irregular translucent mottlings near 

 the margins, more pronounced at the posterior extremity, and from six to eight 

 clusters of minute circular glands on the dorsum anterior to the anal aperture. 

 Stigmatic clefts (^/f^j'. 6,7,8) deeply incised and expanded internally, forming semi-

 six, stout, with rounded extremities, one of them considerably longer and 

 stouter than the others. Marginal hairs small, simple, pointed. No sub- 

 marginal tubercles. Antenna with eight joints, the divisions between fourth 

 and fifth usually incomplete and varying in position ; third and fourth without
