the female insect. But a more careful examination showed it to 

 be of hymenopterous origin — presumably the empty pupa of some 

 parasite. It is curious, however, that the female Coccid seemed in 

 every case to be uninjured. 



My examples of this interesting species were collected by Mr. 

 John Pole on an unidentified shrub at Tangalla. The scales look 

 like warty excrescences on the twigs of the shrub, and in spite of 

 their size are very inconspicuous. 



The specific name is suggested by the social habit of the male 

 larvae and pupa, which, together with one or more females of the 

 same generation, are grouped beneath the covering scale of the 

 parent insect.
