now, seems to commence the gall) is subglobular, of a rich-red 

 colour, the abdominal region very slightly protruding and 

 tapering; the longitudinal diameter of the insect is about 

 ^in. Antennae very short and rather thick, with four joints, 

 of which the first and fourth are longer than the other two ; 

 the fourth is globular, and bears a few hairs, of which one is 

 rather slender. Feet rather long, the femur thick, and the 

 tibia and tarsus slender ; on the trochanter is a long hair ; the 

 tarsus is as long as the tibia ; claw slender, digitules long fine 

 hairs ; there is one very long knobbed hair on the tarsus above 

 the digitules. Abdomen terminating in two very minute 

 tubercles with long setas. There is a row of rather strong spines 

 on the ventral margin of the body. 



Larva not observed by me, but Mr. Froggatt tells me that 

 it is pale-pink in colour, flattish and elliptical ; antennae very 

 short and stout, with four joints ; feet slender, claw long. 

 He gives the length of the larva as about gVn. This would 

 make it nearly three times as long as the second stage — an 

 abnormal condition amongst Coccids. 



The male pupa is found, as stated above, in the gall of the 

 female, embedded in white cotton, each pupa occupying a cell 

 in the cotton ; and all pointing in the same direction, the 

 arrangement being very similar to that of cartridges in a 

 bandolier ; and the cotton is curled in a ring to fit the interior 

 of the gall. The pupal skin is white, the red body of the 

 insect showing through it. The form is elongated, slender, 

 tapering posteriorly to a sharp point ; the separation of the 

 head and thorax can be detected. Length of the whole about 



Adult male bright-red, the antennae and feet yellow ; wings 

 slightly iridescent ; eyes four, two dorsal and two ventral, 

 smooth and black ; ocelli two. Antennge of eight joints, the 

 first two short and thick, the rest slender and moderately 

 long, the length of each decreasing slightly from the third ; 

 all the joints bear several hairs. Feet slender, pubescent ; 

 the tibia is strongly spurred ; claw small and slender ; 

 digitules fine hairs. The abdomen is not very long ; the 

 segments seem to be only two or three, slender and tapering, 

 and terminate in a circular orifice through which protrudes 

 the penis, an organ which is slender and very elastic. In a 

 male just before emergence from the pupal cell it protrudes 

 as a slender seta nearly as long as the body, but it is capable 

 of being retracted almost entirely within the abdomen, and 

 also of being extended until it reaches a length three times 

 that of the whole body. When fully extended it is seen 

 to consist of eight or nine joints, and to terminate in a slightly 

 clavate divided tip bearing a few short hairs.
