Distal joint of legs with astraightand truncate spine. Antenne usual, 
minutely ringed. 
Adult ? .—Length, about 1.96 mm.; fore-wing, about 2.4 by 1.6mm. ; 
length of hind tibia, 0.8 mm.; length of hind tarsus, 0.56 mm.; length 
of front tarsus, 0.32 mm.; color, bright yellow, legs and antennz paler; 
wings very broad, and rounded distally. Wings marked with more or 
less circular spots of brownish black. In fore-wings, along cephalic 
margin, are three spots about equidistant, and farther distad, on curve 
of wing, is a spot somewhat farther from the third spot than are two 
and three from each other. There is a spot on the margin of outer 
‘audal curve of wing and three spots on the caudal margin, which, 
however, are not equidistant, as in the spots on cephalic margin. 
Within the area bounded by the distal fork of the vein are two spots, 
and within the area bounded caudad by the proximal branch are from 
three to five spots. In hind-wings there is a spot on outer cephalic 
margin, and on the outer caudal margin are two spots. There are two 
spots in the area bounded by the distal fork of vein, and likewise two 
spots in the area bounded caudad by the proximal branch of vein. 
Head as seen from above acute cephalad, and margined with deep red- 
dish or brownish black, continuous with eyes which are of same color, 
Joint 1 of antenne short, subcylindrical, distal end irregularly notched 
or toothed. Joint 2, thick, club-shaped, about three times longer than 
basal and bearing two or three setz on outer lateral surface. Joint 
3 quite long—quite twice the length of fourth. Distal joint short, 
terminating in a single seta. 
Received by the Division of Entomology at Washington from Dr. 
F. Noack, Instituto Agronomico, Campinas, Estado de S. Paulo, Brazil, 
on leaves of a myrtaceous plant, March 30, 1898, and again from Dr. 
Noack, on same plant, June 14, 1898. The writer has also received 
specimens of this insect from Prof. T. D. A. Cockerell, to whom they 
had been sent by Dr. Noack. The adults are unique, in the genus 
Aleurodicus, from the more or less circular spots on the wings. Div. 
Ent., Nos. 8010 and 8115. Type pupa-case, 8010, described from nine 
specimens, and specimens on leaf, .rom Professor Cockerell. Type, 
adult @. 8115, described from two specimens.
