34 SCIENCE BULLETIN, No. 18. 



Adult female dull orange to yellowish brown, with darker markings and 

 spots all over the central portion of the derm. Length, | of an inch. In the 

 adult form, swollen and rounded in the centre, elongate, narrowed behind, 

 often with one side of the cephalic portion curved to one side. 



A great deal has been written about this species. There is a list of 88 

 references to it in Mrs. Fernald's catalogue. Douglas {Entomologists' Monthly 

 Magazine, 1887) describes the male coccid. Maskell and Douglas have 

 written regarding the affinities of Lecanium hesperidum and L. lauri, but the 

 latter is now considered only a variety of the former. Another variety, L. 

 hesperidum var. pacificum, has been described from the Galapagos Islands.

Found upon the branchlets of Acacia longifolia and several other species 

 of wattles, in the neighbourhood of Sydney, New South Wales. Allied to 

 Lecanium scrohiculatum. 



The adult female is convex, also flanged on sides and front ; dorsum con- 

 vex, rounded, rising up from the outward flange. Bright, shining, usually 

 dull yellow to brownish, clouded with dull red patches, with many small 

 pits, but without any circular tubercules. Length, nr inch. 



Cleared in oil, specimens are dark reddish-brown, finely tessellated with 

 darker lines, and central part blackish, with a short reddish stripe on either 

 side containing pale yellow spots. 



Cockerell placed this species and L. scrobictdatum in the genus Akermes 

 with some South American coccids, " distinguished by their globular form 

 round chitonous areas on the skin, and microscopical tessellation of the 

 iarvEe."

This is a more or less tropical species, supposed to be a native of the West 

 Indies, and spread chiefly with hothouse plants and on tropical fruits. It is 

 not recorded from Austraha in Mrs. Fernald's catalogue, but I have specimens 

 upon custard apple (Anona reticulata), sent from Darwin (Northern Terri- 

 tory) by Mr. G. F. HUl.
