of first segment with long liairs ; internal surface of second segment coiicnve nearlv 

 as in Acheroiitiicae, but densely scaled ; third segment conical, naked at end, 

 projecting as in Coci/tiiis. Antenna of even width from near base to hook, very 

 slender in ? , with long end-segment, which is rough with long broad scales ; 

 j)enultimate segment as long as high {S), or a little longer, the preceding ones 

 gradnally much higlier than long ; hook long and slender. Tibiae not spinij ; 

 segment 1 of foretarsns as long as tibia, but shorter than segments 2 to 5 together, 

 with three rows of spines externally, row 1 being doubled ; there are, moreover, 

 numerous intermediate spines, so that the rows become irregular, spines of normal 

 row 2 a little longer than those of row 1 ; first segment of midtarsus one-fourth, that 

 of hiudtarsus one-third longer than the other segments together; comb of midtarsus 

 basal, followed by a number of thin and short bristles or spines, so that the remainder 

 of row 4 appears to be separated from the comb by a gap ; spines of row 3 of 

 first hindtarsal segment gradually longer basad, forming a comb of rather stout 

 spines ; spurs long, very unequal, short one of midtibia half the length of long one, 

 or less ; long distal one of hindtibia one-third shorter tlian the first tarsal segment ; 

 pulvillus present, parouychium with tu-o lobes at each side. Distal margin of 

 forewing sinuate before posterior angle. 



Early stages unknown. 



Hab. Africa and Madagascar, occurring most likely also on the Comoro 

 Islands. — One species. 



As explained above, this genus connects the Acheroittiicae with the Sphingicae. 

 The prolonged third palpal segment it has in common with Gocytius{= Ampkoni/x); 

 an obvious similarity with one species of Coajtius {('. cluentius) exists also in the 

 tenth abdominal tergite of the S .

6 ? . Segments 2 to 4 of foretarsus almost black. 



(?. Tenth abdominal tergite curved, dilated at the end, which is divided into 

 three lobes ; the side-lobes are broad, obliquely rounded, while the middle lobe is 

 gradnally narrowed to a jioiut (PI. XXVI. f. 25. 26. 27), the tergite resembling tluit 

 of ( '. cluentius ; sternite long, dilated at end, truncate-sinuate, the sides turned 

 upwards as triangular lobes. Clasper round at end, ventral margin almost straiglit, 

 i)bli([ue; a small patch of modified scales ; harpe (PI. XXXV. f. lo) basally with a 

 high obli<iue ridge, vertical upon tiie ]>lane of the clasper, mesially dilated-rounded 

 dorsally, apex truncate, with the edge raised, produced dorsad into a short hook, 

 apical part of har])e clothed with stifi" hairs ; a patch of long bristles above the 

 base of the harpe. Penis-funnel prolonged dorsally, rounded at end, forming a 

 half-cylinder, whic:h surrounds the penis-sheath and is deeply sinuate ventrally 

 at the base : the funnel is armed with two lobes (PI. XXVIII. f. 30, p-f) ; penis- 

 sheath ending in a short, flattened, obtuse process which is separated from the 

 sheath on one side by an incision.
