of numerous short thick spines and a few short hairs. Each 
stigmatal area is characterized by three or four flattened spines 
and twenty to twenty-five small round spinnerets. The 
dorsal surface bears a submarginal row of about twenty-six 
of the peculiar pyriform glands, as in the preceding species. 
The abdomen bears a group of round spinnerets about the 
genital opening, while the derm of both surfaces bears nume- 
rous large tubular glands. 
Hab. Ypiranga. On the stems of Baccharis genistelloides, 
var. trzmera, Baker. Many individuals are infested with a 
a small hymenopterous parasite. Not common. 
This species is placed in this genus provisionally ; perhaps 
it would more properly belong to Ceroplustodes, Ckll. 
Subfamily Draspryz. 
Genus ASPIDIOTUS, Bouché. 
Aspidiotus (Odonaspis) janeirensis, ILempel. 
Adult female scale elongate, white, the posterior end 
rounded. Pellicles light yellow, placed on the extreme ante- 
rior end. Ventral scale thick, with the dorsal scale forming 
a complete sac which encloses the insect. Length 3°50 millim.; 
width 1:25 millim. 
Adult female oval, pink, 1-770 millim. long and 1:230 millim. 
wide. The pygidium is thick, light brown, and chitinized, 
and is differentiated into five plates, the median longest, 
narrowest, and three-lobed, the others irregularly notched 
and toothed. The lateral margin of the two segments, just 
preceding the pygidium, is also chitinized and plate-like. On 
both the dorsal and ventral surfaces, between the ablominal 
segments, are what appear to be narrow chitinous bands, but 
in reality are narrow rows of small glands or spinnerets. 
There are three groups of circumgenital glands present, 
forming nearly a continuous arched row. The anterior group 
consists of about twenty-seven glands and the lateral groups 
of about one hundred and six glands each. Around each 
anterior spiracle there is a group of about forty-five spinnerets, 
and around each posterior spiracle a group of about thirty-six 
spinnerets. The derm is thin and transversely striated. The 
antenne are present as minute tubercles with one hair. The 
margin of the pygidium and the other abdominal segments 
bear many small glands. Rostrum very large. Anal orifice 
situated just behind the anterior group of spinnerets. 
Hab. On the Ilha das Flores, in the Bay of Rio de Janeiro. 
Collected about the joints of grass and covered by the leaf- 
sheath.
