Richard L Vane-WriGHI & Michael BOPPRÉ: Adult Morphology and the Higher Classification ol Bia Hühner. Figs 33-41: Bia actorion (L.) sensu lato. Macrophotographs (33, 34) and scanning electron micrographs (35—41) of hindwing an- terior androconial organs. 33 hair tuft in resting position, obscuring 34 patch with modified scales: scanning electron micro- graphs: 35, 36 hair bases exhibiting 'click' mechanism; 37 fine structure of hair; 38—41 patch scale bases and scale fine structure are unexceptional but the scale undersides are not perforated (40, U). Scale bars: 33, 34: 2 mm: 35: 100 urn: 36, 37: 5 urn: 38: 211 um; 39: 50 um; 40: 20 um; 41: 10 um. Egg. Spherical, with 25-30 longitudinal ribs and as many as 50 transverse ridges (Freitas et al. 2002: 120, fig. la). The eggs are thus comparable to those of Brassolini, which have 30-60 transverse ridges ( Narope: Casagrande 2002: figs. 1,2), and are unlike those of Satyrinae, which never have as many (Freitas 1999). First instar larva. The head capsule lacks scoli but has numerous long, branched or plumose setae (Freitas et al. 2002: figs. lb,c). A very similar condition can be seen in some Brassolini ( Narope: CASAGRANDE 2002: fig. 4). FREITAS et al. (2002: 119) note that the newly hatched larvae are active, moving around the hostplant unlike "the sluggish behaviour of typical sa- tyrines". Later instar larvae. Later instars have three pairs of scoli on the head capsule (Freitas et al. 2002: 12!. figs ), typical of most Brassolini other than Brass (cf. DeVries 1987: fig. 32 E. 1-8; Casagrande 2002: fig. 3e). According to Freitas et al. (2002: 121). Sa- tyrinae only have one pair of such scoli; however. \\ hile this is generally the case, arguably Elymnias Hühner. 1818. also has three pairs (Igarashi & Fl kl D\ 190": 85-89).
