Callidrepana brunneola Holland, 1893 : 172. [Poor figure.]

 Uranometra brunneola (Holland) ; Gaede, 193 1 : 50. 



Description, q, $. Palp, front of head, and narrow band bordering posterior margin of 

 eyes brownish scarlet. Vertex of head and upper surface of antennal shaft buff. 



Dorsal surface of thorax brown, with scales of anterior margin white-tipped ; ventral surface 

 buff. Front surface of whole of fore leg brownish scarlet, remainder of leg buff. Mid and hind 

 leg buff, sometimes with trace of scarlet on front surface of mid leg. Shape and colour-pattern of 

 wings as in Plate 14, fig. 330. Ground-colour of both wings brownish buff speckled with brown. 

 Fore wing with arcuate, brown antemedial fascia ; large, dark brown discocellular spot ; 

 oblique, brown postmedial fascia from near apex to a point over half-way along anal margin from 

 base of wing ; apical area of fore wing darker than rest of wing ; dark streak extending from near 

 apex to discocellular spot ; fringe dark brown proximally, pale brown distally. Upper surface 

 of hind wing with brown antemedial fascia bordered distally with broad, diffuse, brown band ; 

 wing otherwise unmarked ; fringe as for fore wing. Under surface of fore wing pink, lightly 

 speckled with grey ; usually with well-marked, grey postmedial fascia. Hind wing pink or dull 

 yellow beneath, lightly specked with grey ; without fasciae. 



Coloration of abdomen doubtful. 



<$ genitalia (Text-figs. 225-227) : basal lobe of valve well developed ; aedeagus swollen 

 apically, with broad, spinose process ; eighth abdominal sternum deeply emarginate posteriorly ; 

 eighth tergum as in figure. $ genitalia (damaged in both females examined) : heavily 

 sclerotized dorsal plate of eighth segment probably distinguishable from that of angustipennis ; 

 signum a single, invaginate, spinose cup. 



Measurements. A.P.R. : £. 5 ; $.3. Wing : <$. 13-0, 12-5-140 mm. (3) ; $. 160, 

 I5-5-I6-5 mm. (2). 



Discussion. The colour-pattern of the upper surface at once separates this 

 species from angustipennis. In brunneola, unlike angustipennis, an antemedial 

 fascia is present on the fore wing, and the postmedial fascia meets the anal margin 

 at a point over one-half distance from base of wing to tornus. In the male genitalia 

 the larger lobe at the base of the valve, the differently shaped aedeagus and saccus 

 process, and the more deeply emarginate eighth sternum separate this species from 

 angustipennis. The simple signum characterizes the female genitalia. 



No individual variation, or sexual dimorphism in coloration or wing shape has 

 been found in the material available.
