 sented b_v tlie ?. Antennae short and stout, 

 7-jointed, 3 much longest, formula 3 (71) 

 (i5) (46). Tarsal digitules extending about

 secretion. Antennae apparentl3' 7-jointed, 

 formula 43 (12) (567). Digitules of claw

 but smaller and elongate, with the exuviae 

 towards one end. 5 orange, subcircular, 

 sometimes reniform, 4 groups of ventral 

 glands, cephalolaterals 4 to S, caudolaterals 

 5. Two pairs of rounded lobes, median 

 largest, not contiguous. Plates forming a 

 scaly fringe. Piedras Negras. Mexico, on 

 leaves of an undetermined plant (Townsend). 

 Near to A. uvae, Comst.

 circular to suboval, 3 mm. diam., only 

 slightly convex, dirty gray; exuviae sub-

 the lobes. Anal orifice less than its length 

 from hind end. No grouped ventral glands 

 seen. On Yucca, Cindad Poifirio Diaz, 

 Mexico (Townsend). Near to A. boivreyi, 

 Ckll. 



A. duplex, n. sp. — ^ scale about 2% mm. 

 diam., subcircular. moderatel\' convex, dark 

 blackish-brown with the laige i"ound e\u\iae 

 nearly to one side and orange. $ pale 

 orange, 4 pairs of lobes, the median very 

 large, with parallel sides, the others small;
