(J ?. Tongue reaching b.asal fourth of alidomeu. Pal]ius somewhat pnijecting, 

 visible from above, rather narrow, end-surface much smaller than in Frot<niihiili/x and 

 allies, second segment longer than first. Antenna about 2 mm. shorter than H' 

 of forewing : end-segment conical, about two and a half times as long as basally 

 high, with the scales forming a longer tuft. Abtlominal sternites without spines. 

 Tibiae not spinose, rather shorter than the respective first tarsal segments ; fore- 

 tibia ending in a long thorn ; spurs very unequal, two pairs to hindtibia, long 

 terminal one as in Compsogem about one-si.Kth shorter than the first tarsal segment; 

 pulvillus and paronyehium present, the latter with two slender lobes at each side. 

 Discal margins of wings entire ; apex of forewing truncate-sinuate between S('* and 

 SC ; D' as long as, or longer than, D^ ; D- of hindwing curved or angled, R- central 

 or below centre, D' longer than D''. Clasper and eighth tergite with f rid ion-scales. 

 Larva not known. 



Hah. Madagascar, Comoro Islands, and East Africa. 

 Two species. 

 Nearest to Compsogem. 

 Key to the sjieeies : 



Forewing above with four costal olive patches, 

 the third at subcostal fork elongate, reaching 

 to R^ . . . . . ■ ■ . lf>3. B. cocqucreli. 



Forewing above with two costal olive patches, 



the second and third being scarcely traceable 154. B. iifricniiHS.

(S ? . The two subspecies of this peculiar insect differ in the shade of the 

 ground-colour, the shape of the wings, and the form of the tenth abdominal 

 sternite (<?). 



cj. P]ighth sternite mesially minutely sinuate, the edge of the segment being 

 mesially bent inward. Tenth tergite long, slender, strongly comjiressed, pointed, 

 curved ; sternite nearly as in Protam/juli/x sulphurea (PI. XXIII. f. 4), angles rounded, 

 apex entire or sinuate. Clasper sole-shaped, aj)ical edge strongly concave basally ; 

 patch of friction-scales longitudinal, elongate-halfmoon-shaped (PL LVIII. f. 33), the 

 scales minute, bidentate ; harpo siiort, distally raised into an obli(]uely transverse 

 rida;e (PI. XXXI. f. 8). Penis-sheath similar to that of Auipbjptcrax gannascuK. 



? . Not dissected. 



Hull. Madagascar and Comoro Islands.
