ISCHNASPIS F1LIPORMIS. 211 



pale, or bright yellow, sometimes with a faint trace of 

 orange. The female only occupies a small portion of 

 the piiparium. Rostral filaments extending to about the 

 middle of the body. Pygidium short, broad, and widely 

 rounded ; median lobes and first two plates within 

 a broad, shallow emargination ; dorsal area (fig. 7) 

 almost covered with an irregular lattice-work design, 

 formed apparently by the thickening of the dermis, 

 the outer anterior walls of which are symmetrically 

 branched. Anus a little below the centre. Midway 

 between the anus and the margin on each side are 

 one or two circular glands, in character resembling 

 those of the ventral surface. Circumgenital glands in 

 three groups (fig. 8) ; the anterior group consisting of 

 3 4, the posterior laterals of 4 6 : the former group 

 is placed immediately opposite the anal opening ; the 

 latter group a little below it, and opposite the first 

 marginal projecting pore. Median lobes well developed, 

 are widely separated, and have their margins broadly 

 and evenly rounded, and finely serrate ; second and 

 third pairs small, placed closely together, are of a 

 similar shape to the median pair, but the serrations are 

 absent. Between the median and second pair of lobes 

 is a spine, two spine-like plates, and a large, blunt, 

 projecting pore ; there is a spine over the third lobes, 

 which is followed by a third plate ; equidistant between 

 the latter and the fourth plate is a second marginal 

 projecting pore, less pronounced than the first ; on the 

 rest of the margin beyond are 4 6 equidistant plates, 

 and about the same number of small spines. 



Puparium of the male (fig. 4) elongate ; sides re- 

 semble the anterior portion of the female puparia both 

 in colour and form; and the character of the larval 

 exuviae does not differ. 



Long. 1 mm. 



Male unknown. 



Habitat. Mr. Douglas (1. c.) says it is "abundant in 

 the conservatories of the Royal Botanic Society on the 

 leaves of various palms, Strychnos, Myristica, and other
