Mr. A. Hempel on Brazilian Coccidse. 393 



Hob. Jundiahy, State of Sao Paulo, on the bark of an 

 indigenous tree. Collected by Mr. C. Schrottky. 



Several hundred small Hymenopterous parasites were bred 

 from this species. As in /. brasiliensis, the parasites are 

 present in the adult, and do not prevent the eggs from 

 hatching, and consequently are but a slight check to this 

 species. 



Subfamily Goccinm. 



Genus Eriococcus, Targ. 



En'ococcus brasiliensis, Ckll. 



Adult female reddish brown, oval in outline. Anal ring 

 with 6 long hairs. Antennas variable. In some specimens 

 joint 3 is the longest, while in others joint 4 is the longest, 

 being 44 long; joint 1 is 22 long. All joints except joint 3 

 bear one or more hairs. 



Male sacs of same consistency and colour as those of the 

 female, but a little smaller. The adult male is dark brown 

 in colour. Antennas variable, usually of 10 joints, but 

 sometimes with onPy ° or 9 joints: joints 2-9 are dilated 

 at the distal ends ; joint 2 is very thick, being twice the 

 diameter of joint 3. Approximate formula: 10 2 (9 3) 8 7 

 (4 5 6) I. All the joints bear many small hairs, while in 

 addition to these joints 8 and 9 each bear one, and joint 10 

 bears five large thick hairs. Thorax large ; abdomen wide, 

 with several hairs on the margin of each segment. Genital 

 spike short and acuminate. Wings ordinary, the pocket, for 

 the insertion of the balancers, being large. Balancers or 

 halteres long ; the last joint long and slender, with a large 

 hook at the distal end. Claws toothed as in the female. 



Length *95 millim. ; extent 1*87 millim. 



Bab. Ypirauga. Usually crowded on the ends of the 

 twigs of Baccharis dracunculifolia, DC 



The insect is active until just before gestation, when it 

 constructs a closely felted sac, occupying three or four days 

 for the work. 



Eriococcus perplexus, Hempel. 



Largest female sacs 11 millim. long, 3*5 millim. wide, and 

 1*75 millim. high ; spindle-shaped, widest caudad of the 

 middle. Snowy white, closely felted, pointed, and with a 

 small opening at the posterior end. The dorsal surface is apt 

 to be slightly flattened and shows traces of transverse furrows.
