in addition to possessing a single pair of cribriform plate clusters, 

 have the dorsal whorls of 8-shaped pores less pronounced and have 

 a larger number of quinquelocular pores in the anterior spiracular 

 bands. 



Green regards hibisci as its closest relative. His careful and 

 elaborately illustrated work on the Ceylon species and his work on 

 the other Indian species should supply a basis for separating indicus 

 from the other species of the Oriental region.

The Maskell collection includes four slides of this species, two 

 of "adult female, 1895," and two of "adult female, 1896," all in 

 fairly good condition. The unmounted specimens, placed under No. 

 68, include a few on a cardboard square and a number on a portion 

 of the host plant. Supplementary mounts have been obtained from 

 this material, and it is largely from these that the following re- 

 description has been prepared. 



Adult female. — Test and body as described by Maskell and Frog- 

 gatt ; body of mature female, as mounted, nearly circular, except for 

 protruding apex of abdomen, maximum length 2.2 mm., width 1.9 

 mm.; early adults smaller and distinctly longer than wide; derm 

 membranous; antennae reduced to fairly elongate, incompletely 

 2-segmented tubercles, hardly invaginated at apices, but with several 

 stout apical setae; middle and hind legs represented by stout curved 

 spines set on flattened bases, but fore legs with only somewhat en- 

 larged bases; spiracles stout, each with a relatively heavy band of 

 quinquelocular pores (more than 200) running from spiracle to mar- 

 gin, those forming the posterior bands not split into two groups as 

 in many other species; beak stout conical, incompletely 2-seg- 

 mented; marginal setae, as such, apparently not developed; no .spi- 

 racular spines; dorsal and ventral derm setae small and inconspicu- 

 ous, those placed ventrally in the genital region somewhat larger 

 and more evident; 8-shaped pores numerous, in two distinct sizes, 

 the larger having a maximum long dimension of about 22ja, the 

 smaller size with a long dimension of 15/a or less, the larger pores 

 confined to an elongate cluster on each margin of the protruding 

 posterior portion of the abdomen, and to clusters on each side of the 

 bands of quinquelocular pores running from spiracles to margin, 

 plus an occasional pore in or near the posterior mid-dorsal area; 

 smaller 8-shaped pores widely distributed, showing to some extent
