AKT. 2 BEETLE LAEVAE OF GALERUCINAE BOVING 11 



mandible immediately behind the teeth projecting into an obtuse 

 low proceF-s; third tooth much larger than the rest, subrectangular 

 and with multiserrated edge. Penicillus absent; two setae present 

 on exterior side of mandible. 



MaxilJa (figs. 56, 59, 61, 63). — Lacinia soft, denseh' setose, and 

 with half a dozen long, spine-shaped setae; galea smoothly chiti- 

 nized, having about the same number of similarly shaped setae as 

 lacinia and a short, pointed cone-shaped appendix between them. 



Postlabial harul (tig. 636). — Semicircularly curved. 



Prothorax (figs. 1, 2). — Shield with a finely aciculate surface and 

 on each side a large, irregularly variolose depression; in the sagittal 

 line a sharp furrow and at the end of this a small triangular deepen- 

 ing; margin thick and rounded, carrying a few short and thin setae. 

 Epipleural area with a small, round, slightly chitinized projec- 

 tion carrying a few soft, short hairs. Prehypopleurum ( = epi- 

 sternum) with a j^ellowish sclerite and a few soft setae. Posthypo- 

 pleurum ( = epimeron) with no distinct sclerite; a few soft setae 

 present. Jugular region membranous. Eusternai plate median, 

 large, transverse, crescent shaped, and with a single row of several 

 setae. Each sternellar plate roimd, with a single seta. 



Mesothorax and iiietathorax (figs. 1, 2). — Prescutal and scuto- 

 scutellar areas separated by a deep transverse furrow. Prescutum 

 of mesothorax with a small, but distinct sclerite on each side close 

 to the sagittal line. Prescutum of metathorax without distinct 

 sclerites. Scuto-scutellum both of mesothorax and metathorax car- 

 rying a small sclerite on each side close to the sagittal line. Alar 

 area tlat, freely projecting over epipleural area below, and carrv'ing 

 on an irregularly bilobate sclerite several fine setae. Spiracular area 

 with a single seta. Epipleural area bearing a small, rounded, shin- 

 ing, sttose projection. Prehypopleural and posthypopleural areas as 

 in prothorax. Eusternai and sternellar sclerites weak. 



First to eighth ahdominal segments (figs. 1, 2). — Prescutal area 

 separated from scuto-scutellar area by a deep transverse groove; 

 prescutal area without any sclerite. Scuto-scutellar area with an 

 unpaired median, rather small and scale-like sclerite. Parascutal 

 area not sharply defined and without sclerites, Epipleural lobe 

 projecting, cone-shaped, and provided with a chitinous top .with a 

 few short setae. Hypopleural area soft, with two moderatelj' long 

 .setae. Eusternum soft with a single seta on each side. Sternellum 

 (phis parasternum) soft, with two setae. 



Ninth ahdmninal segment (figs. 1, 2). — Pygidial shield subrec- 

 tangular, transverse with broadly rounded corners, leatherlike with 

 discal part more glossy; about a dozen moderately long setae lo- 

 cated in the hind margin in a single irregular row. Ventral part of 

 segment with about lialf a dozen setae on each side.
