amined) with the tips of epistomal angles projecting beyond its anterior 
margin. 
Labrum as broad as clypeus, almost semicircular. 
Mandibles, a deep fossa just behind the median transverse carina is 
apparently constant. 
PROTHORAX about times as broad as long ; pronotum strongly 
declivious and narrowing anteriorly, most strongly chitinised in a trans¬ 
verse zone in front of the middle and in a small sharply bordered trian¬ 
gular patch on each lateral margin behind the middle ; median line well 
marked, occasionally incised, lateral margins impressed, lateral angles 
subrectangular, posterior margin sinuate. 
Frosternum, eusterum small triangular, margins entire, presternum 
deeply bilobed. 
Thoracic spiracle more than twice as long as abdominal spiracles, 
deepset. 
ABDOMEN. Ambulatory ampullae, dorsal series simple, smooth, 
ventral series each with a V shaped mark composed of dark punctures or 
impressed dots, the apex of the V directed posteriorly. In some specimens 
this mark is scarcely visible on the anterior segments, but is always 
present on segments 6 and 7. 
Segments 7, 8 and part of 9 with strong pleural folds. Fleural 
discs visible on segments 1—6, the last very feebly marked. 
Anal (i 9th ) segment twice as long as and broader than 8th segment, 
sides tapering from near the middle, to the anus which is formed by 3 
prominent lobes meeting in a Y shaped suture of which the vertical 
branch is nearly equal in length to the other two united. 
Length 42-62 mm. = lf to 2 T 7 F inches. 
Largest larva: width of thorax 11 mm.; length of anal segment 
12 mm.
