Fig. 6. Eriococcus tillandsiae n. sp. : A, antenna; B, types of spines; C, type of 



duct. 



Morphological characteristics. Adult female (on slide) about 3 mm. 

 long. Spines confined to the margin of the body except for a few ex- 

 tremely small, sharply-pointed spines on the dorsum. Marginal spines 

 (Fig. 6B) along the abdomen arranged in groups of four to six on each 

 segment, two of these being large, tapering and sharply pointed and 

 sometimes slightly curved, the others of the same shape but smaller. 

 Along the head and thorax the spines are more numerous, forming an 

 irregularly double or triple series and are more nearly of the same size. 

 Anal lobes prominent, weakly chitinized, each dorsally with two spines 

 which are practically of the size and shape of the larger marginal spines, 

 ventrally with three quite long setae, the longest of which is perhaps 

 three-fourths as long as the anal lobe setae. Antennae (Fig. 6A) 7-seg- 

 mented, quite large and long. Legs with the tarsus slightly longer than 

 the tibia, the claw with a denticle, the posterior coxae with very few pores 

 beneath. Anal lobe setae only slightly longer than the anal ring setae. 

 Wax ducts (Fig. 6C) with the cups quite deep, symmetrical. 



Genus FONSCOLOMBIA Licht.

 amount of secretion.
