Saiind. Ill the latter, however, the only well-defined 

 iiervure is the subniaij^inal, which ends in an indefinite 

 club with 3 clear pustules, remote from the costa, towards 

 which a linear thickening of the wing membrane stretches. 

 This thickening is doubtless the obsolescent base of the 

 marginal vein. In Liporrhopahim there is a single pustule 

 towards the end of the submarginal, but the neuration is 

 normal except that the radius is entirely wanting. The 

 extreme tip of the neuration is abruptly thinned. 



If the minute 4th antennal joint of this insect were 

 overlooked, the antennal formula might be confused with 

 that of the monotypic Pkdyscapus Motsch. (Bull. Soc. Nat. 

 Moscou, vol. 36, p. 47, 1863), which was described from 

 Ceylon and may be a Fig Insect. In his account of 

 P. frontalis {ib., p. 48, t. 2,.f. 6), however, Motschuisky 

 notes the presence of a short radius in the wings, and in 

 the figure the funicle appears to be distally tumescent. 



LiFORRHOPALUM gcii. nov. (Fig. 1.) 



Head short, eyes large, sparsely subpilose. Antenna; scape broad 

 and stout. Funicle slender, the joints from the 6th onwards several 

 times as long as broad. Club long, cylindrical, not wider than the 

 rest of the funicle. Sensoria short produced into long tubular 

 processes. Thorax normal. Wings densely clothed witii cilia. 

 Neuration continued on to the costa, after a single pustule at the 

 origin of the marginal. No stigmal vein. Spiracles small. Abdo- 

 minal tergites not incised posteriorly. 



Genotype the following species. 



Liporrhopalum rutherfordi, sp. n. 



A black or blackish -bi(;\\ii species, only the tarsi and mid til)iae 

 paler. Wings hyaline. 



Head between 1 and ;j l)roader than deep. Eye extending to 

 half the depth. Antenna (fig. ]«) about 1 mm. long. Scape and 

 bulla fused, broader than long (4 : .3). Apex of the former rounded, 

 angulate above the jiedicel, 4th joint minute and transverse (11 : 9), 

 nearly completely hidden by the base of the horn-like process on 

 the 3rd joint (fig. 16). Sensoria on 5th joint of normal long 

 Blastojjhagine type with short distal angular jnojections. There- 

 after they are short witli tubular processes. Relative lengths of 

 the succeeding joints, 14 : 10 : 13 : 13 : 17, Avith an average breadth 

 of 3. Both antennae are broken after the 5th. The last joint is
