ROBERT NEWSTEAD. 



short ; anal lobes similar to those in the adult. Margin (fig. 2, 6) continuous. No 

 stigma tic clefts. Stigmatic spines (fig. 2, 6) three, the laterals short, stout and obtuse, 

 the central one more than twice the length of the former. Marginal spines (fig. 2, 6) 

 slightly larger than those in the adults. Tubular glands well within the margin ; 

 there are eleven of these on either side and one opposite the centre of the cephalic 

 margin with a much smaller gland on either side of it ; just within the angles of the 

 anal cleft is a similar small gland. Post-anal pores (fig. 2, c) circular, with confused 

 gratings ; these are arranged in two scattered groups numbering six and five respec- 

 tively ; on the rest of the mid dorsal area are numerous minute circular pores, and 

 a few rather slender spines. Derm cells in a broad marginal zone, forming a polygonal 

 reticulation in the stained specimens. The legs and antennae had been almost entirely 

 removed by a predaceous larva of some kind, whose frass w^as found beneath the 

 bodv of the Coccid.

Larva. Anal lobes well within the cleft, the apical hair long ; two laterals much 

 shorter ; there is also a single minute spine seated on the inner edge in a marked 

 depression. Antennae and legs robust ; the former of six segments, the 3rd about 

 twice the length of the 2nd. Marginal hairs extremely small. Stigmatic spines 

 three, the laterals exceedingly minute ; the central one very long and equal in 

 length to the third segment of the antennae. No special dorsal or marginal glands 

 traceable.
