Genus Allopulvinaria, nov. 



Adult 5 naked above, very convex and distinctly segmented. Lower surface 

 concave, filled with a compact powdery mass of wax which projects around the 

 margins. Antennae somewhat rudimentary, of 4, 5 or 6 segments. Legs well 

 developed. Anal ring with numerous (12?) hairs. 



Larva elongate and narrow ; anal tubercles produced, each with one long seta. 



Type, A. subterranea, sp. n. 



21L Allopulvinaria subterranea, sp. n. (Plate vi, fig. 246). 



Larva active, pale pink, eyes pigmented, body elongate and narrow. Anal 

 tubercles long, each with one long seta. 



One-fourth grown $ with 4-jointed antennae, and marginal hairs as in Lecanium. 



Adult 5 viviparous, 7 mm. long, 4'5 mm. broad and 4 mm. high. Dorsum 

 roundly arched ; segmentation distinct, the segments roundly ridged. 



The body is red, faintly flecked with white wax. Underside flatly concave, 

 abdominal portion plainly segmented. Legs small, brown. Anal plates small, 

 brown, from between which protrudes a double fine pencil of white wax. Lower 

 concavity of body fiUed with cushion of white wax which extends sUghtly beyond 

 the margin of the body ; this is not cottany but compact. No eggs were seen, 

 but larvae were present in the white waxy cushion and in the body of the $. 



Antennae 4, 5, or 6-jointed, usually 5. Anal ring with numerous (12?) hairs. 



Anal plates raised, appearing excavate so as more or less to enclose the anal 

 tube from the sides as well as above. Anal groove closed. Integument with 

 numerous simple glands and short acute spines scattered over the surface ; the 

 former especially noticeable in transverse series across the segments.

Genus Protopulvinaria, Ckll. 



The few species which have been described in this genus are similar to Lecanium 

 in their early stages, but may be readily distinguished at maturity by the small 

 white ovisac which is secreted beneath the adult $. In the normal condition this 

 is but slightly larger than the body of the female and protrudes as a white ring around 

 the margins of the body (fig. 248). 



This genus is included in Pulvinaria by Mrs. Fernald in her Catalogue (p. 128), 

 but it would appear that its correct position is between Lecanium and Pulvinaria,
