the Coccid genus Leucaspis. 4d7 



the middle, is usually displaced to a position much nearer 

 the posterior extremity of the body. The four pygidial 

 lobes are conspicuous and prominent, each distinctly 

 trilobulate (fig. 7). Length of pellicle 1*25 to 1'5 mm. 



Lindinger describes the nymph as possessing, on each side 

 of the pygidium, a small group of pores similar to those 

 of the circumgenital glands of the adult female. I have 

 failed to find these organs on the nymphal pellicles of my 

 Indian examples ; but they show a small group of oval 

 dorsal pores occupying the position indicated in Lindinger's 

 figure. 



My examples of the adult female show a longitudinal 

 series of small conical tentacular processes on each side, 

 on a fold embracing the rostrum and the two pairs of 

 spiracles (fig. 8). These do not appear to have been noted 

 by previous observers. The rostral apparatus is unusually 

 large and conspicuous. In addition to the circumgenital 

 series of glands, there are two small supplementary groups 

 (of from 4 to 5 pores) on each side, situated respectively 

 on the two preceding abdominal segments. The pygidial 

 lobes are stout and lanceolate : the marginal fimbriate 

 plates long and slender (fig. 9). 



I have examined two separate gatherings, labelled 

 respectively " on twig of Ficus religiosa, associated with 

 Lecanium nigrum, Calcutta, Jan. 1896," and " on Pepul 

 tree, Rajmahal, Bengal." In the former, the puparia are 

 of a dirty greyish-white colour, while in the latter they 

 (both male and female) are stained of a reddish tint 

 assimilating them to the colour of the bark to which they 

 are attached. Cockerell describes his examples as being 

 " whitish with a strong greyish-ochreous tinge, exactly 

 the colour of the twig on which they rest." It would 

 appear therefore, that the insect has the power of altering 

 the tint of its secretions to match its surroundings.
