clear white ; head cordate, apex in front with several very short hairs. Antcniife 

 (fig. 4) of ten joints, of which the 2nd is the shortest, and is furnished at the base 

 beneath with two very short, blunt, angular spines directed backwards (fig. 4a), all 

 the joints with many fine hairs, the last joint has three clubbed hairs at the apex. 

 Legs slender, with fine short hairs ; the tarsi a little more than one-fourth the length 

 of the tibiae ; there are four ordinary digitules, two on the tarsi and two on the 

 claws. Abdomen with the last three se-nients furnished at the sides with two 

 tubercles, bearing short, stiff hairs, those on the last segment longest. Thorax with 

 a few fine scattered hairs, and a row of hairs arranged wide apart on the apical 

 margins of the abdominal segments. Long) 1 Him. 



Scale of the J glassy-wiiite, something like those of the Lecania, but differs 

 from them in having the margins bet^elled inwardly from above, and there is no 

 anal cleft. Long, 1-25 mm. ; wide, '75 mm. 



? at period of fecundation very elongate, sides parallel, ends equally rounded, 

 pale, or dark orange-yellow, with two broad subdorsal lines of a rich dark carmine, 

 thickly set with small spots of the ground-colour. Dermis with many fine longish 

 hairs, more numerous on the margin. Antennse as in the adult. Legs with few 

 hairs ; trochanter with one very long one ; tarsi two-thirds the length of the tibiae, 

 the latter with one very long hair at the apex ; digitules of the tarsi long and 

 slender, those of the claw very broad throughout their length, and much dilated at 

 their extremities. Rostrum without articulation ; its entire length, including the 

 unexpanded filaments, scarcely exceeds the length of the femur. Anal ring with six 

 slender hairs. Long, 2-50— 3-25 mm. ; wide, "To — 1 mm. 



The description of the adult female and the sac, as given by 

 Signoret (/. c), agrees in almost every particular with my specimens, 

 except that he shows in his figure of the antennae the 4th and 5th 

 joints the longest. 1 find in all my examples that the 3rd, 4th and 

 5th are the longest ; the other joints and the arrangement of the hairt^ 

 are as shown in his figure. 



Signoret states that he examined ichneumonized individuals, which 

 will at once account for the slight discrepancy in the relative length 

 of the joints of the antennae. 



I find parasitized Coccids frequently have their appendages, &c., 

 malformed. As a proof that Signoret examined parasitized examples, 

 he remarks that " the sac is open at one end, but at this place the body 

 of the female closes it." Now, the habit of the female after gestation 

 is to drop from the sac, and perish outside. Of the many hundreds of 

 examples examined, I never found other than parasitized individuals 

 to remain in the sac ; which are very rare instances, indeed, in this 

 locality. The females cast their skins prior to gestation, and to effect' 

 the removal of the same from the anal cleft, I saw one example make 

 free use of its anal ring, which it constantly protruded in order to 

 remove the skin. The females are active up to the time they secrete
