SCALE INSECTS (' COCCIDyE ") OF AUSTUALIA. ia 



The Australian variety E. lacujalus is distinguished by liaviiig a smooth 

 sae. Maskcll says : " I attach it to the above s])ecies on account of the short 

 blunt conical form, of the very luimerous dorsal spines, and the shoit antennae 

 %vith six sulie(|ual joints, characters distinguishing E. niuJtisjiiviitf from 

 E. ]i((Uidus in which the spines are slender and the third anterinal joint 

 long, and fioTU E. ndthhyi, which lias no dorsal spines and scn en-jointed 

 antennH\"" 



325. Eriococciis t)iuUiHpi)ius. Cat. Coccida-, ].. 76. 



Eriococcus jiicta, n.sp. (i ig. 62). 



This species was collected by Mr. J. L. Newman near Perth, Western 

 Aiistralia, u])on the branchlets and leaves of an undetermined species of 

 Eucalyptus. 



The sac globular, very compact, well separated from each other, formed of 

 a stout leathery delicate white secretion, with the centre of the apex some- 

 times tinted with red, fitting close to the bark, the anal portion turned up 

 slightly, a large opening in the hind margin. Length, j^ of an inch. 



Adirlt female reddish, rounded, tapering to the anal extremity, pear- 

 shaped. Legs normal. Antennae composed of six joints like those of E. 

 coiiaqeus. Anal tubercles somewhat similar, but shortej- and broader. 

 Anal ring with six long hairs. Derm very thickly covered with short 

 ■cylindrical, truncate rods, and small circular spinnerets, but no true s})ines. 

 Length, ,\ of an inch. 



This nright be taken for a very small solitary form of Eriococcus coriarciis, 

 but differs in the structure of the anal tubercles, the rods, and absence of 

 . spines on the dorsum, as well as in size.

The type was described from specimens on one of the Mallee Uums {Euca- 

 IjIpiHS (/racilis) collected by Mr. C. French, jun., in Nortli-western Victoria. 

 I have a fine series obtained by Mr. McKeown on the leaves of another 

 eucalyptus grcnving at Bomen, near Wagga, New South Wales. In the 

 latter specinuMis the larvjf appear to have a habit of ci'awling to the tips 

 of the long, slender leaves, where the adult sacs are clustered, or sometinu's 

 in a regular row on the side of the leaf. In specimens received from .Mr. 

 French the sacs are much more genei'aliv scattered ovei' the leaves. 



Adult female reddish brown ; legs, antenna' and anal tubercles darker 

 brown; elongate oval, slightly longer than broad. Antenna' six-jointed, 

 first bi'oad, second short, thiid h)ngest, fourth and fd'th short, latter 

 longer than fourth, sixtli as long as the fourth and fifth combined, elongate 

 to the ti|) with scattered hairs. Legs well developed ; tarsus long, with the 

 digitules spatulate on tarsus, with another pair of hair-like digitules clubbed 

 at the tips. Anal lobes short, stout, blunt, broad at the base: edges rounded 

 to the ti|) : the inner parallel edges serrate, with a single spinv hair on eitlier
