diameter i i-2 to 2 mm.; exuviae sub-central or central, 

 yellowish orange in color; margins of scales of both sexes 

 grayish and flaky. Male scale oblong ovate, about 2-3 mm. 

 by I mm., exuviae near cephalic end, same color as in female 

 scale. 



"Body of female insect circular or oblong, 3-4 mm. to 

 4-5 mm. long. In much dried specimens the margins of the 

 penultimate and antepenultimate segments are drawn back 

 until even with the anal margin, giving the body much the 

 form of A. reniforniis, a coincidence however that cannot be 

 considered as any more than purely accidental. 



First pair of lobes of ultimate ventral segment of female 

 well developed, approximate at apex, rounded, acutely 

 notched on outside about one-third distance from apex to 

 base; second lobe with mesal half well developed, longitud- 

 inal axis of interior half parallel to longitudinal axis of median 

 lobe; third lobe rudimentary. Incision between mesal lobes 

 well rounded at its ai)ex; incision between first and second 

 lobes well marked, widest at apex; incision between second 

 and third lobes slightly smaller; margin outside of third lobe 

 often minutely crenate. A small chitinous process at inner 

 base of median lobe, smaller one at outer base; large club- 

 shaped process mesad of and adjoining first incision, small 

 process on outer margin; chitinous curved process around 

 second incision often broken at apex of incision so as to 

 appear as two separate processes, one on each side of the 

 incision. A pair of spines outside base of median lobe, a 

 pair from each second and third lobe and one or two on 



♦The writer has not been able to detect any definite structure.s thatimay be 

 designated as plates, nor do they appear to be mentioned in any of the papers already 

 pubUshed upon this species. However on the anal margin, outs-ide the third lobe, 

 there appear in several of > the specimens examined, "short stubs" similar to but 

 thicker than the bases of the spines. These appear very much like the rudiments of 

 plates. Their absence in many of the specimens can doubtless be attributed 

 to their destruction in preparation of the specimen, it being difficult to so prepare a 

 specimen as to preserve the plates in good condition.
