margin of each median lobe, and four larger ones on each side beyond, 

 namely at the outer margin of the middle lobe, at each side of the second 

 lobe, and besides the third lobe. Two rows of orifices run parallel with 

 the margin, somewhat as in Maskell's figure of A. corokitz. Four groups 

 of ventral glands, the cephalolaterals of about seven, the caudolalerals 

 of about eight. Anal orifice a considerable distance from the hind end. 



Hab. On Agave rigida, at Hope, Jamaica. Collected by Mr. 

 J. J. Bowrey, sent by Prof. C. H. T. Townsend. 



This interesting species is noteworthy for the form of the scale 

 of the female, which is elongate with the exuviae to one end, after 

 the manner of the male scale of A. biformis and other species. 

 Females with young were sent, but the male has not yet been 

 observed. This is not the first Coccid found on Agave, for, in 

 1888, Mr. Douglas described Coccus {Gymnococcns} agavium, 

 found on an Agave which came from North America, but still 

 unknown to collectors in this countrv.
