EGBERT NEWSTEAD. 



the 2nd and 3rd or marginal series are partly incomplete and replaced by a series of 

 pores. Cephalic plate large and not divided medially ; pores exceedingly minute and 

 very widely separated ; a few only on each plate. A submarginal tubercle is present 

 in nearly all of the sutures. Anteimae (fig. 20, 6) of seven segments, of which the 3rd 

 is slightly the longest ; the 4th-7th, inclusive, exceptionally long and varying but 

 slightly in their relative lerigths. Stigmatic clefts (fig. 20, c) small, narrow, but 

 clearly defined ; spines three to four (usually three), very short and stout, ^vith 

 bluntly rounded tips. Marginal spines (fig. 20, c) almost invariably broken away, 

 but the few which remained in the preparations are exceedingly minute. Anal lobes 

 (fig. 20, d) obtusely rounded distally. 

 Length, 5-6'5 mm. 



Fig. 20. Lecanium chelonioicles, Newst., sp. n., $ ; a, a, dorsal aspect of adults ; 

 h, antenna ; e, stigmatic cleft ; d, anal lobe ; e, antenna of second stage $. 



Female, second stage. Very elongate ; cephalic margin slightly broader than the 

 posterior margin. Antennae (fig. 20, e) of six segments, the 6th much the longest. 

 Legs rather short, first pair about equal in length to the anteimae. Stigmatic spines 

 three in number, and very like those in the adult $, but relatively smaller, and the 

 laterals slightly curved. Marginal spines exceedingly minute, simple. 



Male piiparium. Thin, glassy and transparent ; surface finely rugose and divided 

 into eight plates ; central plates unusually narrow. Length, 3 mm.
