mate slightly longer than the rest. Feet rather long, of 

 normal form ; lower digitules very slightly dilated. Anal 

 tubercles very minute and inconspicuous ; anogenital ring with 

 six hairs. Mentuui trimerous. Epidermis with many very 

 minute circular spinneret-orifices. Margin bearing some 

 conical spines not set close together ; and some more of 

 these spines are scattered on the cephalic region. 



Female of the second stage purplish-red, elongated, flattish ; 

 length about ^in. ; not covered with cotton, but with sparse 

 white meal on the dorsum and a few cottony tassels at the 

 posterior extremity. Antennae of six joints. 



Larva purphsh-red, flattish, elliptical ; length about ^in. 

 Antennae of six rather thick joints, the last much the longest, 

 the rest subequal. Anal tubercles very small, convergent, 

 bearing moderate setae. 



Male pupa enclosed in white cotton ; usually aggregated in 

 masses on the leaf. 



Adult male brownish-red ; length about ^in. Wings not 

 iridescent. Antennas of ten joints, the third, fourth, and tenth 

 longer than the rest. Dorsal eyes two, ventral eyes two, 

 ocelli two. Abdominal spike short and very broad at the base, 

 having the appearance of two basal lobes with a conical pro- 

 cess. Feet moderate ; at the extremity of the tibia are several 

 strong spines. 



Hab. In Demerara, on an aquatic palm, Nipa fruticans. 

 My specimens were sent to me by Mr. J. W. Douglas, who 

 has allowed me to describe the insect here. 



In outward appearance this resembles rather a Ripcrsia, 

 from the character of the cottony processes of the adult 

 female ; but, some specimens showing seven and others eight 

 joints in the antennae, I attach it to Dactylopius. I believe it 

 to be quite distinct.

The specimens of this insect which Mr. Crawford sent to 

 me a few years ago were clustered between sheets of bark in a 

 mass of cotton, mingled with larvae and males. I have lately 

 received from Mr. W. W.Froggatt, of Sydney, a large number 

 on leaves of Eucalyptus robusta. These specimens agree en- 

 tirely with my South Australian types as far as regards the 

 anatomical characters of the antennae, feet, and anogenital 

 ring, and also the feathery fringe of the larva ; but instead 

 of secreting cotton they are naked, each resting in a pit or de- 

 pression in the leaf which exactly corresponds to its outline. 

 As these specimens were sent to me in alcohol I am unable to 

 say whether in nature they would have any cotton or not ; 

 but in any case the point is not important in view of the ana-
