Prothorax relatively small with lateral carinae often explanate, and dentate; prosternum relatively short in front of coxae, with narrow intercoxal process; procoxae conical and projecting below sternal process, trochantin exposed or concealed; cavities open internally; externally open or closed. Mesocoxae approximate to almost contiguous; cavities broadly open laterally, bordered both by mesepimeron and metepisternum; perimeter of each cavity sometimes with several deep pores. Elytra seriate or striate (except Peltastica), with 10 or 11 punctate rows or striae; scutellary striole present or absent. Metasternum with long median suture and with transverse suture which may be interrupted or incomplete; anterolateral portion of metepisternum with elytral interlocking device; metacoxae somewhat motile, approximate, extending laterally to rim of elytra, with weakly developed plates. Metendosternite with stalk short, median process well-developed, anterior tendons approximate, lateral arms narrow and curved. Hindwing with 5 to 6 major veins; oblongum cell of hind wing absent; medial fleck of hind wing absent; wedge cell of hind
wing well developed; anal lobe present. Legs relatively short trochanter attached obliquely to femur; tibial apex with 2 small spurs (except Laricobius which has an apical comb); tarsi 5-5-5, tarsomeres simple (except Laricobius with tarsomeres 1-3 lobed below); claws simple.
