158 Mr. T. D. A. Cockerell on 



joints measuring in /j, : (1) ring-like, (2) 21-27, (3) 33, 

 "(4) 45, (5) 18, (6) 16-18, (7) 24-27. Breadth of mouth- 

 parts about 130 fi. Anterior legs with femur + trochanter 

 100 fx (width of femur 30), tibia 78, tarsus 66. The tarsus 

 has a deep constriction near its middle, so that it looks as if 

 2-jointed. Claw-digitules about 21 fi long (twice as long as 

 claw), stout, with bulbous base and large knob. 



Larva about 375 fi long. 



Hab. Zapotlan, Mexico, numerous on small branches of 

 shrub with small pinnate leaves like Rhus, July 6 (Townsend). 



This small species has not the wax divided into plates ; it 

 reminds one a good deal of C. alholineatus , but is much 

 smaller, and the lateral chalky lines are narrower and closer 

 together. The specimens are adult and have produced many 

 young. 



Cey-oplastes viarmoreus, sp. n. 



? . — Scale long, 6-6|, lat. 5-6^, alt. 4-5 raillira., rounded, 

 wax thick, not divided into plates, white, irregularly suffused 

 and marbled with madder-red ; sides bulging below, with 

 two narrow bands of chalk-like secretion. Sometimes the 

 wax of two or more individuals runs together. Denuded 

 female about 3^ millim. long, not very convex, with a dorsal 

 crest and six conspicuous pointed lateral projections; caudal 

 horn very short, pyramidal. 



Boiled in KHO the insects impart only a slight reddish 

 stain to the liquid, but they nevertheless contain much 

 madder-red colouring-matter. Skin after boiling yellowish 

 ferruginous, semihyaline, without conspicuous glands. 

 Diameter of mouth-parts 130-140 /*. Femur -f trochanter 

 108-150 ^, tibia 70-123, tarsus 40-78; the smaller size 

 refers to the anterior and the larger to the posterior legs. 

 Claw-digitules with rather large knobs. Margin without 

 spines. Anal plates about 90 /u. long and 36 broad, shaped 

 like the elytra of a beetle, and situated near the hind margin 

 of a large subcircular or subtriangular orange-ferruginous 

 chitinous plate (520 /i diara,)., whicii exhibits many glaud- 

 orifices. Antennas about 270 /i long, slender, 7-jointed, witii 

 a long 4th joint ; joint 7 short and blunt, 1 long. Measure- 

 ments of joints in /ti: (I) 30-36, (2) 33-40, (3j 45, (4) 75, 

 (5) 23, (6) 24, (7) 27. 



Ilah. Zapotlan, Mexico, on composite near Parthemumy 

 July 7 (Townsend c& Boyd) ; also on sage and Cataipa 

 ( Townsend) . 



C. warworeM5 is easily recognized by its appearance; the
