Thorax one-fifth longer than wide. Prothorax trapezoidal, 
with posterior margin nearly straight. A weak spine at the pos- 
terior lateral angle. Metathorax at first converges slightly and 
then widens to the abdomen; posterior margin twice weakly con- 
cave forming a weak median angle; a series of five long hairs in 
the posterior angles, and on each side between the latter and the 
middle a series of four similar hairs; central and hind portion of 
prothorax and central portion of metathorax yellow-amber col- 
ored. Legs ample, yellowish, pale margined. 
Abdomen slender, elongate, slightly widening to segment 5, 
then tapering gradually to segment 9; segment 1 conspicuously 
shorter than the others; segments 2 to 8 with transparent lateral 
plates immediately within which occur longitudinal bands of 
darker color; general color pale amber. Segment 2 with a short 
spine at the posterior angles; segment 3 with three similar spines 
at the posterior angles; segment 4 with a spine and a longer hair 
at the posterior angles; segment 5 with one long and two shorter 
hairs at angles; segment 6 with three shortish hairs at angles; 
segment 7 with three longish hairs at angles; segment 8 with two 
longish hairs at the posterior lateral angles, one just within the 
lateral plate, and four along the posterior border; segment 9 very 
deeply notched, forming a pair of terminal claw-like appendages 
at the inner borders of which near the base are a pair of shortish 
hairs, while a series of six short hairs occur laterally thereon.
