ally, well separated from lobe area, with six setae and two rows oi 

 pores, apical seta of lobes smaller than anal ring setae; derm with 

 three distinct pore types, triangular, multilocular disk and cylin- 

 drical tubular, and with lanceolate spines (cerarian), slender peg- 

 like spines and slender pointed setae of varying sizes; larva oval, 

 antennae 6-segmented, legs normal, dorsum with triangular pores 

 and slender peg-like spines, anal ring normal, with six setate, anal 

 lobes developed, each with a pair of large lanceolate spines dorsally 

 and a subapical and subbasal seta, only the anal lobes with indica- 

 tions of cerarii. 



As will be noted from the preceding description, this species was 

 incorrectly described by Maskell, and consequently very inaccurately 

 placed. Cockerell in creating the genus Epicoccus for this species 

 placed it more correctly, stating that it was " Dactylopiid," which 

 presumably meant that he followed his key to the genera of Coccidae 

 in placing it, and so referred to what is called the subfamily Dacty- 

 lopiinae of the Fernald Catalogue. In this catalogue the genus is 

 placed just before Phenacoccus^ which locates it still more correctly. 

 The genus is actually a member of the group, probably a subfamily, 

 of which Pseudococcus may be looked upon as the typical genus. The 

 • writers are not sufficiently familiar with this group of genera to state 

 whether or not this genus is sj^nonymous with any other previously 

 or subsequently described genus, nor to f)lace it with any accuracy in 

 the series, although from present knowledge its affinities appear to 

 lie with Ripersia and its relatives. 



Genus LACHNODIUS Maskell. 



Genotype. — DactyJopius eucalypti (Maskell). 



Reference.—F^Yniildi, Cat. Cocc. World, 1903, p. 95. 



Maskell included three species in this genus, one previously de- 

 scribed and two new, at the time he originally established it, and 

 the type does not appear to have been fixed until the publication of 

 the Fernald Catalogue, in which eucalypti is indicated as the geno- 

 type. 



There are six slides of this species in the Maskell collection, one of 

 "adult female, Australia, 1886," one of "adult female, 1893," one of 

 larvae, Australia, 1886," one of " larvae, 1894," one of " adult male. 

 Australia, 1886," one of " antennae and feet of male, Australia, 1886." 

 The 1886 slides are evidently the types of the species. In addition 

 there is a verj^ small amount of material in position on the host, under 

 Maskell No. 206. From this material the following description, sup- 

 plementary to that given by Maskell, has been prepared. 



Adult female. — Body of mounted female nearly circular, antennae 

 7-segmented, similar to the Eriococcus type rather than to the Pseu-
