Classification
Diagnostic Features of Larvae
- Larva. Form elongate, subcylindrical; integument firm, shining, smooth, sparsely covered with short, fine, light yellowish hairs. Head subtrapezoidal, rapidly narrowing on front, mouth-frame slightly corneous; epistoma broadly emarginate in middle; clypeus thin, short; labrum transversely oblong, thin; mandibles rather broad, basal half reddish brown, one-third width of distal, latter piceous, shining, sulcus on outer face; antennae rather stout, first joint globular, equal to slender third, shorter than second, supplementary very minute; two bead-like, prominent ocelli below antennae, not enveloped by gena, which is beset with a number of rather stiff bristles; last joint of maxillary palpi about twice the length of transverse second, about equal to last labial; process of palpifer and that of first maxillary joint, large, distinct. Prothorax narrowly rectangular, depressed; pronotum twice as wide as long, posterior area embossed, very regularly and finely striate, sparsely haired, no median suture; sternum narrow, transverse; ventro-lateral sutures very obliquely diverging; sternellar fold not distinct beyond spiracle. Mesonotum and metanotum granulate, shining, former with an inverted v-shaped impression (i.e., scutellum distinct), the latter with a transverse suture. Legs well developed, four-jointed, femur and tibia about equal in length to maxillary palpi. Abdomen cylindrical, segments deeply constricted; ampullae small, bearing two irregular rows of small shining tubercles, last ventral substriate. Pleural disc a very large, dull, finely striate area on second, third and fourth abdominal segments. Spiracles suborbicular, very small (about size of ocellus), peritreme thin.
