216 THE COCCIDAE 



meats obscure, segments variable in length, third twice as long 

 as fifth, distal segment with two thick compressed setae on distal 

 end, antennal formula 35142; abdomen broader than head and 

 thorax, cephalic part of ventral aspect with two much com- 

 pressed thick setae; caudal abdominal segments with glandular 

 areas on dorsal and ventral aspects. Brazil on a woody shrub 



fluminiensis Hemp. 

 aa. Antennae of adult female with less than five segments. 



b. Antennae of adult female with four segments; cerores found on 

 all abdominal segments and generally distributed; scale of adult 

 female fluted. 



c. Body of adult female purplish red; scale conical with apex at 

 center. England, West Indies, United States, Mexico on 



Angraecum, Rodriguezia angraeci Ckll. 



cc. Body of adult female colorless, except brown plates of abdo- 

 men; scale conical with apex on one side. Mexico on Hibiscus. 



angraeci hibisci Ckll. 



bb. Antennae of adult female with three segments; cerores arranged 

 in group on each side of abdominal segments one to three; scale 

 of adult female not fluted. Ceylon. socialis Green. 



Scutare Brittin. Scale of female is flat, subcircular, glassy, 

 fringed, and ventral scale is complete. The adult female is widest 

 through the thorax. The antennae consist of six segments and the ros- 

 trum of two segments. The thoracic spiracles are represented by two 

 pairs. The legs are present and normal in form. The abdomen is dis- 

 tinctly segmented with distinct chitinized areas. The anal lobes are 

 distinct, subtriangular. On each side of each abdominal tergum within 

 the margin there are four short cylindrical setae, these are continued 

 around the margin of the thorax. The tergum of the abdomen between 

 the anal lobes and fifth segment is provided with a row of similar setae 

 on each side of the meson. The anal ring located between the anal 

 lobes, bears six long fine setae. Adult insect with covering scale does not 

 resemble other species of subfamily. The presence of an anal ring with 

 anal ring setae and a scale fringed with glassy threads of wax needs to 

 be confirmed. A single species, fimbriata Brittin, is the type. 



Fagisuga Landinger. A single species, triloba Lindg., is the type. 

 It occurs in Chile on Nothofagus. The scale is about 1 mm. in diameter, 

 without exuviae, conical, not fluted, dirty white in color. The body is 

 0.69 mm. long and distinctly segmented. The antennae consist of four 

 segments. Its formula is 4312. The body on each side adjacent to the 

 lateral margins of the denticulate projections is provided with several 

 tooth-like projections.
