claw, 25 //. long. Hairs and digitules nearly as in Kingii. The most 

 marked difference is in the ovisac. Kingii secretes a loose, fluffy, 

 shapeless ovisac, while this var. secretes a compact, elliptical ovisac, 

 very little larger than the female, in which the female lies partially 

 embedded. The ovisac resembles that of an eriococcus very much.

Dactylopius Azale/E, n. sp. 



Adult ? . About 3 mm. long, about 2 mm. wide. 



Flattened ellipsoidal, rather pointed at the ends. Colour of dried 

 specimen, purplish-gray secretion, white, granular, practically hiding the 

 true colour of the body. I>ateral filaments very short on the thorax, 

 increasing in length toward the anal extremity. Caudal filaments not 

 conspicuously longer than those of posterior segments of the abdomen. 

 The lateral and caudal filaments are just easily seen with the naked eye. 

 Epidermis with numerous spinnerets. Dorsum with scattered, rather 

 large, hairs. Ventrally the hairs are quite large and rather numerous, 

 especially on the posterior segments. Largest hairs on posterior 

 segments are 60 \i long. Sides with rows of spinneret spine areas. 



Antenn?e colour reddish, 8-jointed; medium size, all the joints have 

 quite long hairs. The joints are rather variable in their relative lengths ;
