Diagnostic Features of Larvae
- Larva. Form subcylindrical, elongate, robust; yellowish-lemon tinged; integument tough, shining, very sparsely clothed with coarse brownish-yellow hairs. Head strongly depressed, side slightly constricted behind middle; labium transverse, widest behind, slightly notched in front, densely haired on anterior half; mandible robust, from side not twice as long as condylar width, cutting edge obliquely emarginate; antenna] ring entire; one pair of distinct ocelli. Ventral mouth-parts rather chitinized; palpi slender, last joint of maxillary palpi acute, shorter than last labial; anterior edge of hypostoma broadly curved; gula protuberant. Prothorax rectangular, depressed, strongly so anteriorly; pronotum anteriorly smooth, posteriorly very finely asperate pubescent; eusternum well defined, a group of hairs in center; sternellum entirely finely asperate. Mesonotum smooth or anteriorly finely asperate; metanotum, mesosternum, and metasternum tuberculate, these asperate pubescent. Abdomen nearly cylindrical; dorsal ampullae bearing four rows of asperate tubercles, the ventral two rows ; epipleurum protuberant on all segments; pleural tubercle broadly oval to roundly rectangular, bearing a chitinous pit at each extremity and two setae. Spiracle oval, strongly chitinized. Pupa. Body beset with yellowish-brown bristles, those of abdominal terga arranged in two very prominent, closely set blotches; last segment armed with a strong, recurved, chitinous spine, bearing several minute teeth on the margins.
