bers, but is free — at least so far as is known at present — from the 

 attacks of S. larvarum. The larva of Charagia virescens are the 

 only known forms to attack rata timber. From the researches 

 of Sir Walter Buller, it is evident that the Sphoeria occurs in 

 many parts of the native forests in the North Island away from 

 rata trees (Entom. 1895, 174). A perfect examination of the 

 habitats of S. larvarum, and of the various sized larvae found 

 attacked by this entomophyte, is indispensably requisite in order 

 to ascertain if one or more species of larva is attacked. 



The numerous empty burrows of various depths of Charagia 

 virescens occurring in rata trees suggest that the larvae were 

 attacked by the Sphoeria and sickened, and left their burrows to 

 perish in the humus around the trees where the fungus nourishes. 

 My young friend's interesting discovery of the Charagia larvae in 

 the rata logs places the matter beyond doubt that they are 

 occasionally attacked by S. larvarum in their burrows.

SOME NEW GOCGIBM OF THE SUBFAMILY LECANIIN^. 

 By T. D. A. Cockerell, N. M. Agr. Exp. Sta. 



Pulvinaria marmorata, n. sp. 



? . With ovisac 11 to 13 mm. long, the scale itself 4 mm. ; ovisac 

 3 mm. broad, cylindrical, firm, scarcely grooved, not adherent to 

 objects which touch it ; shrivelled female marbled with ochreous and 

 black, margin dark, dorsum with a broad light longitudinal band, 

 patches of glassy secretion here and there. Eggs pale yellow with a 

 slight pinkish tinge. 



? . Boiled in caustic potash, stains the liquid light brown. Skin 

 colourless, legs and antennae yellow-brown. Antennae 8-segmented, 

 formula (13)248(56)7 ; first four segments not far from equal, 2 about 

 two-thirds the length of 3. Bostral loop short. Legs ordinary; 

 femur more than twice as thick as tarsus ; tibiae about three-fifths 

 length of tarsus. Claw stout, rather long ; all the digitules slender. 

 Margin with short simple spines, few in number. 



? . Before forming ovisac Lecan ium-like, very convex, 4£ mm. 

 long, 3 wide, 3 high, yellowish brown, speckled with black, with many 

 little nodules of glassy secretion ; back with a broad light band, 

 across which dark lines mark the sutures between the segments. 

 Younger examples are light yellowish, nodulose, with hardly any dark 

 mottling. 



Hab. Dripping Spring, Organ Mts., New Mexico, April 24th, 

 1898 (Ckll.). It occurs on a small bushy perennial herbaceous 

 plant, which I have not seen in flower. It has sublinear leaves 

 dotted with glands.
