NEW SPECIES OF DIASPINE SCALE INSECTS. 13 



Ty.'pe. — Bureau of Entomology No. 14129. On Hake sp. and an 

 undetermined plant. Raventhorpe, West Australia, collected by 

 George Compere (Nos. 968 and 990), received at the Department 

 February, 1902. 



Note. — This species in scale characteristics and large anal orifice 

 reminds one of Aspidiotus camellix Sign. ; in its pygidial characters 

 it is more like A. destructor Sign. It differs distinctly, however, 

 from both of these species, as indicated in the description. It occurs 

 massed rather thickl}'' on the smaller twigs of the two food plants. 

 It does not seem to coincide with any of the species described by 

 Maskell, although, when Maskell's types are examined, it may fall 

 to one of his species. 



ASPIDIOTUS (s. str.) MEYEKI n. sp. 



(Plate I, fig. 2.) 



Scale of female: Elongate oval, 1.5 to 2 mm. (or more) in length; 

 ver}' convex; exuvite subcentral; larval secretion whitish except as 

 obscured b}^ extraneous matter; main or subsequent secretion dull 

 resinous brown; larval secretion and exuvia easil}^ lost, exposing the 

 large, bright orange colored second exuvia; scale adhering very 

 loosely to the leaf and easily dislodged, leaving the insect exposed; 

 inner surface of scale covered with snow-white secretion which 

 entirely conceals the exuvia. 



Scale of male: Not certainly identified, but apparently the same 

 general type as female, except as to size and number of exuvia. 



Adult female: Long, oval, distinctly robust or convex, 0.7 to 

 0.9 mm. broad b}^ 1 to 1.4 mm. long; hyaline in balsam mount; 

 anal plate broad, rounded, in general hyaline, 0.32 mm. broad by 

 0.20 mm. long; two pairs of simple normal lobes, median largest 

 and most chitinized, 0.012 mm. in diameter; both lobes with two 

 minute shoulders, often worn, and shoulders obscure; some distance 

 beyond the second lobe is a very low, rudimentary, lobular projec- 

 tion, with difficulty distinguished, terminating in a nipple or pointed 

 tip; lateral teeth wanting; incisions moderate, normal; paraphyses 

 practically wanting; plates lower than lobes, broad, many-branched; 

 2, 2, 3, and, following the rudimentary lateral lobe, 4 or 5 narrow, 

 branched plates; spines ver}^ short and inconspicuous; anal opening 

 large, circular, 0.2 mm. in diameter, larger than a single median lobe 

 and about two lobes distant from base of lobes; paragenitals in five 

 groups, 2-4, 3-3, 3-4; dorsal pores large and conspicuous, in rows 

 counting from the center as follows: 3-4, 5-7, 6-7, with a few addi- 

 tional pores in obscure rows of 2, 3, or 4 pores each; basal thicken- 

 ings represented by two narrow median transverse rods, and the
