of mango, together with a few Aspidiotus personatusj Corast. 

 (Toionsend). Div. Ent. 7973. 



As Prof. Townsend remarks, this very curious little species 

 resembles a lately-hatched lepidopterous larva. It is closely 

 allied to Aspidiotus Bowreyi^ Ckll. 1894, which must be added 

 to the fauna of Mexico, as Prof. Townsend found it at Fron- 

 tera on " Pitahaya," an edible cactus, June 5, 1897 (Div. 

 Ent. 7831). 



Aspidiotus (Chrysomphalus) calurus, sp. n. 



? . — Scale about 1^ millim. diam., approximately circular, 

 slightly convex, covered by the epidermis of the bark, except 

 the shining black exuvise, which are exposed and very con- 

 spicuous. There is a thick ventral scale, which makes it very 

 hard to extract the female. 



$ . — After boiling, brownish yellow or yellowish brown ; 

 general form circular, but the caudal portion is narrowed on 

 each side, produced and rounded, having a curious appear- 

 ance. From the sides of this portion cephalad the margin is 

 gently rounded until it reaches a deep notch, forming the 

 further (anterior) wall of which is a large tooth-like projection ; 

 the cephalad side of this latter gradually slopes to another 

 notch, beyond which is a rounded eminence. The last 

 visible suture before the caudal portion is marked by a broken 

 dark chitinous band. No groups of circumgenital glands ; 

 anal orifice some distance from hind end ; two long and seven 

 short pairs of tubular processes, the short ones considerably 

 longer than the lobes ; the innermost long ones further apart 

 than either from the outermost. Four very well-formed pairs 

 of lobes, the first rather narrow, pointed, with a notch on the 

 outer margin ; the second, third, and fourth broader and 

 similar to one another, except that the second and third have 

 two notches on the margin, while the third is minutely serrate. 

 The median lobes are near to each other, but not touching, at 

 the base ; the intervals between the other lobes are wide, 

 that between the third and fourth rather wider than a lobe. 

 Beyond the fourth lobe the margin is crenate, with about 

 five little prominences. Plates short and inconspicuous. 



^ . — Scale brownish, with concolorous exuvise, with a small 

 well-sculptured dot and ring.

A very distinct species, easily known by the form of the 

 hind end of the female.
