half the length of the tibia and tipped with a strong denticulate claw, which hears a 

 spine at the base. 



The body is an elongate oval, rounded, and covered with hue hairs; anal ring 

 large, bearing six hairs. 



The body is coated with a calcarecnis, laminated secretion. The shape and ar- 

 rangement of this secretion cannot be given as the specimens were not in good condi- 

 tion. The length of ovisac, about 2 mm., length of insect, 1.6 mm. 



Habitat: On Coniea hitea (821) and Scalesia microcephala 

 (254), Tagus Cove, Albemarle Island. 



" This appears to be close to O. prcetonga Dougl., btit the last an- 

 tennal joint seems to be too long for that species. It cannot be satis- 

 factorily identified without specimens showing perfect lamallae of the 

 secretion. I think it probable that this is a new species. " O. 

 ultima Ckll., from the Argentine Republic, has the waxy lamellae al- 

 most exactly as in the Galapagos species, so far as those of the latter 

 can be seen. The legs and antennse of ultima are much darker than 

 the Galapagos species. The last antennal joint of the Galapagos 

 species is very much longer than in ultima, and of quite a different 

 shape. This joint of the Galapagos species is much nearer to prcetonga 

 than to ultima " (Cockerell). 



Asterolecanium pustuians Ckll. (Plate IV, Figs. 5-11.) 



Scale of female. — Test of adult female smooth, shining, hard, semi-transparent,

 yellow ; around the edge a fringe of long, pinkish-white, glassy filaments. Under 

 the compound microscope the scale shows many glassy filaments all over the dorsal 

 aspect. Average length, exclusive of fringe, about I mm.

 teimK and legs absent ; margin of the body with a row of " figure-of eight " glands 

 in pairs ; segments distinct ; the posterior segment furnished with two lobes each 

 bearing one long and two short spines ; anal ring small with six hairs ; mouth parts 

 rather small, but well chitinized. 



First larvil stage. — Elongate oval, gradually tapering toward posterior extremity, 

 flat ; segments distinct ; color red ; mouth parts very large, rostral loop long ; an- 

 tennae apparently lo-segmented, the last segment bearing long hairs : .08 mm. long, 

 formulae, 10, 2, i , 6 (4, 7, 8) 9, 5, 3, 9) ; legs subequal, normal, tibia shorter than 

 tarsus, digitules on tarsus fine, hair-like, knobbed, digitules on claw stout and short ; 

 posterior end of the body with two lobes, each bearing one long and two short hairs; 

 anal ring bearing six hairs ; length of body, . i mm. 



Pupa. — Length, .9 mm.; width, .4 inm.; reddish brown, antennae and legs pale, 

 antenna; long, reaching to the base of the second legs; wing case large, reaching to 

 the base of last leg ; legs normal.
