of first segment with long luiirs; internal surl'iice of second segment concave nearly 

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

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

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

 j)enultimate segment as long as high (<?), or a little longer, the preceding ones 

 gradually mnch higher than long ; hook long and slender. Tibiae yiof spim/ ; 

 segment 1 of foretarsns as long as tibia, bnt 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-fonrth, that 

 of hindtarsus 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 ; S2iurs long, very unequal, short one of midtibia half the length of long one, 

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

 jmlvillus present, paronychium with two lobes at each side. Distal margin of 

 forewing sinuate before posterior angle. 



Early stages unknown. 



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

 Islands. — One species. 



As explained above, this genus connects the Acheivntiicae with the Sjihingicae. 

 The prolonged third palpal segment it has in common with Cactjtiiis (= Aiiiphoni/x) ; 

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

 tenth abdominal tergite of the c?.

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



c?. 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 

 gradually narrowed to a point (PI. XXVI. f. 25. 26. 27), the tergite resemliling that 

 of ('. i-litrufius; sternite long, dilated at end, truncate-sinuate, tiie sides turned 

 upwards as triangular lobes. (jlas])er round at end, ventral margin almost straight, 

 ulilique; a small jiatch of modified scales ; harpe (PI. XXXV. f. 13) basally with a 

 high oblique ridge, vertical u])on the plane of the clasper, mesially dilated-rounded 

 dorsally, ap<'\ truncate, with the edge raised, produced dorsad into a short hook, 

 apical part, of liarpe clothed with stiff hairs ; a jjatch of long bristles above the 

 l)aHe of the harjie. Penis-fnnnel prolonged dorsally, rounded at end, forming a 

 half-cylinder, which surrounds the penis-sheath and is deeply sinuate ventrally 

 at the base ; the funnel is armed with two lobes (PI. XXV III. f. 3(1, p-f) ; penis- 

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

 Hheatli on one side by an iijcisi(^n.
