The specips upon which this genii's is founded was oiiguially collected br 

 Mr. Crawford, of Adelaide, 8out]i Australia, who gave it the MS. name of 

 En'tmi (/fobosiim. but did not describe it. Maskell, thougli somewhat 

 doul)tful of its affinities, droi)ped Crawford's new genus and })laced it in the 

 genus DadylopiKs. Cockerell, studying the species, took it as the type of 

 Crawford's discarded genus, and included a munber of Mexican species. 

 According to Newstead's description of Dactj/lopius hihermcus {Britisl 



Coccuke, vol. ii, |). 172), a rare species found 

 upon grass, it probably comes into tliis genus.. 



In general fonu and structure the adult female 

 is closely allied to that of the genus Dactylo'pius. 

 the differences being that the joints of the 

 antennae are more regular in form, with the last 

 joint often distinctly rounded and of a uniforni 

 shape. The legs are short and thickset. In most 

 sjjecies the anal lobes are very small with a 

 iuiinl)er of s^jines of a lance-headed form. The 

 whole of the epidermis covered with circular 

 orifices, many short rod-like processes, and short 

 s])ines or hairs. 



The adult female is com])letely enveloped in 

 a mass of fine felted woolly filaments or mealy 

 secretion, forming a c()m])lete sac protecting the 

 female and larva-.

and other localities in the western parts of 



New South Wales, jirobalily ranging over a large area with its food-plant. 



this si)ecies was determined by Mr. E. E. Cireen. 



The adult female is enclosed in an elongate oval white sac. convex, but 

 sloping to the extremities: sac com})osed of rather brittle white waxy 

 secretion, like soft eggshell, under which is the female and a compact ma.ss 

 of larva'. Lenuth of sac, '- of an inch. .\diilt female, vellowish lirown.
