ARCTIIDAE AND CTENUCHIDAE FORMERLY IN AUTOMOLIS 63 



Automolis aureogrisea Rothschild; Strand, 1919 : 15. 

 Automolis aureogrisea Hampson, 1920 : 144. 



<J. Basal segment of palp orange with some dark brownish grey dorsally; segment 2 dark 

 brownish grey with some orange at base and greyish white on front surface (except near apex) ; 

 apical segment greyish white. Head orange with white patch on each side posterolaterally. 

 Scape of antenna orange posteriorly, white anteriorly; segments 1-9 of flagellum orange, apical 

 10 or 12 segments white, remainder dark greyish brown. Ground-colour of thorax orange; 

 otherwise zs flavescens. Tymbal organ with up to 50 grooves. Prothoracic coxa and trochanter 

 orange; front surface of femur dark greyish brown, otherwise orange; tibia dark greyish brown, 

 except for greyish white patch towards apex on front surface and orange area at base of front 

 surface continuous with orange band extending from base to two-thirds of outer surface; tarsus 

 dark greyish brown except for some greyish white scales on rear surface of first segment. Mesotho- 

 racic coxa, trochanter and femur orange, the latter with dark greyish brown zone distally; 

 tibia and tarsus as prothoracic leg. Metathoracic coxa, trochanter and femur orange; tibia 

 orange-yellow, with dark greyish brown distal band and spot (latter opposite proximal pair 

 of spurs); first tarsal segment orange proximally, dark greyish brown distally; remaining 

 tarsal segments dark greyish brown. Upper surface of forewing orange, with small, white 

 spot at base of wing and large, elongate, weakly iridescent, olive (3D2) and brownish grey 

 (7D2) medial marking. Upper surface of hindwing orange-yellow at apex and in anal area, 

 otherwise weakly iridescent light brown and reddish grey, becoming sparsely scaled around 

 androconial patch in cell (cf. flavescens). Under surface of forewing as upper surface, but 

 without white basal spot and with proximal half of medial marking light grey. (This grey 

 area of scales and those of rest of overlap zone between fore- and hindwings apparently andro- 

 conial, being similar in scale-shape to androconial zone on upper surface of hindwing.) Under 

 surface of hindwing orange, with weak iridescence of reddish grey in middle part of wing. 

 Abdomen orange. 



Forewing length: lectotype £ 17-0 mm; <$ i6-o-i8-o mm. 



<J genitalia. As flavescens but valves shorter, pre-apical process longer, and vesica differently 

 shaped and ornamented. 



O. not known. 



Readily separable from both flavescens and pseudoflavescens by the larger size, 

 the shape of the dark, medial marking on the forewing and by the coloration of 

 the tarsi. The male genitalia are also diagnostic. 



There is little individual variation discernible in the available material all of which 

 is from Peru. 



Material examined. 



Automolis aureogrisea Rothschild, lectotype <J, Peru: Carabaya Mts, Santo 

 Domingo, 6000 ft, vii.1902 (Ockenden) (BMNH). 



Peru: i £, Carabaya Mts, Santo Domingo, 6000ft, vi.1902 {Ockenden); 3 £, [Carabaya 

 Mts], Marcapata, '4500 ft' [Marcapata is higher than this according to The Times Atlas of the 

 World, 1968]. 



ASTRALARCTIA gen. n. [Gender: feminine] 

 Type-species: Automolis pulverosa Schaus, 1905 : 215. 



^. Palps extending i-o-i^mm beyond labrum; terminal segment minute. Antenna 

 weakly serrate {pulverosa) or bipectinate {canalis), with row of long setae along crest of each 

 serration. Tymbal organ well developed. Mesothoracic tibia bearing one pair of spurs ;
