144, tarsus 95; tarsal digitules rather slender, about 60 /z 

 long, with rather large knobs ; claw-digitules extending 

 beyond claw, rather slender, but with fairly large knobs. 

 The claw-digitules are more or less swollen at the base, as in 

 C. psidn. Dorsal skin strongly chitinous, ferruginous, with 

 many mostly oval gland-orifices, about 15-30 fi in diameter. 

 Hire and there are large patches of tessellated (honeycomb- 

 like) structure. Antennae about 400 fj, long, 6-jointed, with 

 a very long 4th joint, which has a notch near its end. 

 Measurements of joints in fi: (1) 36, (2) 63, (3) 60, (4) 126, 

 (o) 32, (6) 72. 



Larvce (dried) bright ferruginous. 



Hab. Zapotlan, Mexico, on small branches and twigs of 

 Ft'cus, July 7 {Townsend & Boyd). The specimens were 

 preyed upon by a Phycitid larva. Also collected at Ira- 

 puato, Mexico, on oleander and on a yellow-flowered tree 

 with narrow leaves and a milky sap, July 4 [Townsend'). 



Immature specimens are similar to the original C. Toions- 

 €7idi, which was not observed to grow to anything like the size 

 of the present insect. It is probable, however, that typical 

 Tounsendi grows to a larger size than has been observed. 



Ceroplastes alboh'neatus, Ckll., var. vulcanicus, nov. 



? . — Waxy scale about 14 millim. long, Hi broad, 8 high ; 

 scales on small branches, often confluent; wax very thick 

 and watery, pale yellowish pink, not divided into plates. A 

 central white nncleus, and on each side a depression, below 

 which is a bulging, upon which the bands of chalky-white 

 secretion are more or less visible, often being very distinct. 

 Within, the wax is decidedly pinkish. Denuded female dark 

 red-broun, flattish, 5^ millim. long, 4 broad, about 2 high, 

 with a large narrow dorsal crest ; the anterior and six lateral 

 processes quite long and sharp-pointed; caudal horn short 

 (about 1 millim.) and directed upwards at an angle of about 

 45°. Boiled in KHO the skin becomes hyaline, mottled with 

 brown, with numerous scattered small glands, and here and 

 there ill-defined patches of reticulation. The margin is 

 thickened and presents two rows of small, broad, conical 

 spines, hardly constricted basally. Antennae 7-jointed : joint 1 

 ring-like, short; 2 very broad at base, with the apical third 

 suddenly narrowed and bearing Uf-p bristles, one very long 

 (about 90 /u,) ; 4 has the apical 10 fi suddenly constricted, 

 and just belore the constriction is a bristle. Measurement of 

 joints \n fi: (1) ?, (2) 66-70, (3) 68-70, (4) 105-120,(5) 21, 

 (G) 21-24, (7) 36-40. Anterior leg with femur + trochanter
