ART. 17 MASKELL ASTEROLECANIINAE MOEEISON 9 



proximately circular, diameter 0.7 mm. ; the anal region very slightly 

 protruding; body entirely membranous except, as described later, in 

 the anal region ; antennae represented by flat conical stubs, each with 

 a lateral, acute tip, and a central clear area bearing two pores and 

 a single stout tapering seta : legs wanting ; spiracles stout, somewhat 

 kidney-shaped, each with a single row of tiny quinquelocular pores 

 between it and margin; mouth parts not unusual, the segmentation 

 of the beak obscured ; with an occasional marginal, or perhaps ventral 

 submarginal, slender seta, these more evident near the posterior apex 

 of the body, and with segmental pairs of larger, stouter setae ventrally 

 anterior to the anal region; large 8-shaped pores in a double row of 

 alternating pores for about five-sixths of the circumference, the 

 remainder near the anal region, in a single row terminating on each 

 side somewhat before the a^Dical seta ; no other 8-shaped pores of com- 

 parable size present, but the dorsal surface with a very considerable 

 number of minute 8-shaped pores, each not more than one-fourth the 

 length of a similar marginal pore, scattered, apparently uniformly, 

 over the surface, ventrally with a submarginal row of scattered 

 minute 8-shaped pores of modified shape, shorter oval and less dis- 

 tinctly bilocular; quinquelocular pores represented by a marginal 

 row, accompanying the 8-shaped band and, in general, nearly as 

 numerous as the combined roAvs of 8-shaped pores anteriorly but 

 about half as numerous near the posterior apex of the body, by a 

 single to double row of scattered pores between each spiracle and 

 margin, and by two or three just anterior to each antenna ; multi- 

 locular disk pores each with 9-11 loculi in seven transverse, appar- 

 ently segmental rows in the ventral abdominal region, the pores in 

 the posterior rows closely placed, those in the anterior rows much 

 more scattered ; with a marginal row of minute, circular, apparently 

 simple, disk pores immediately below the row of quinqueloculars and 

 somewhat less abundant than these ; relatively large tubular ducts 

 present, rather numerous, distributed nearly uniformly through the 

 dorsal area; anal area slightly protruding, the lobes not differenti- 

 ated, anal seta stout, about 165^ long, with a stiff seta about 7.5/i 

 long immediately beneath and another about Gyu, long within at the 

 opening of the short, distinctly chitinized, invaginated tube sur- 

 rounding the anal ring; this last well developed for the genus, with 

 pores and six setae, the longest about 28/*. 



No other stages available from the type material. 



Gotype.—C?it. No. 40362, U.S.N.M. 



As with the other Maskell species of Asterolecankmi, an accurate 

 location of this species within the genus is not practicable at this 

 time. From descriptions it seems probable that it is rather closely 

 related to A. tokyonis Kuwana.
