Maskell. — On CoccidaB. 313 



later larva is yellowish-browu, flat, elliptical ; length, about 

 Y^gin. There is a dorsal longitudinal carina, and indications in 

 some specimens of transverse carinas. The margin bears 

 spines as in the adult. Antennae of seven or eight joints, 

 according as we consider a division of the fourth a " false " or 

 a " true " joint. Feet, anal cleft and lobes, and anogenital 

 ring normal. There are many small irregular spots on the 

 epidermis. 



Male pupa covered by a white glassy test of the usual 

 Lecanid form, composed of polygonal plates, flat at the top, 

 with sloping sides and a subelliptical base. The length of 

 this base is about -^Qva. 



Adult male not observed with certainty. One mutilated 

 specimen (w4iich had died when on the point of emergence) 

 was extracted from a test. This specimen is brown, about -^^vo., 

 in length, exclusive of the spike, which is moderately long and 

 slightly cui-ved. A fragment of a wing is hyaline. 



Hah. In Australia, on ilcaczape^jfZziZa (myall). Mr. French 

 sent me several specimens which, he says, came from Goudie, 

 " in the hottest and driest part of Victoria, where it is terribly 

 destructive." 



This insect clearly belongs to Signoret's fifth series of the 

 genus, near to L. cycadis and L. olecB, while at the same time 

 it approaches my L. scrobiculatum in its dorsal pits. Its 

 immense size makes it the largest Leccmium known to me. 

 L. tuliinfercB, Cook, a North American insect, is the only one 

 which approaches it in this respect ; and even Ctenocliiton 

 viridis, hitherto quite the largest of the Lecanid group, is not 

 its equal. 



Genus Pulvinaria. 



Pulvinaria nuytsise, sp. no v. 



Adult female dark-brown, the form, as usual, elliptical at 

 first but shrivelling at gestation, with an elongated narrow 

 posterior ovisac of white cotton. Length of the insect averag- 

 ing yV^- '> of the ovisac, |-in. Dorsum elevated in a median 

 longitudinal ridge, the margins flattened. Antennae of eight 

 joints, of which the third is the longest, the last three the 

 shortest and subequal ; the second bears one long hair, the 

 eighth several short ones. Feet normal; the trochanter and 

 femur have no hairs ; tarsal digitules fine hairs ; digitules 

 of the claw widely dilated. Margin bearing a series of short 

 blunt spines. Abdominal cleft and lobes normal. Mentum 

 conical, monomerous. 



Second stage not observed. 



Larva yellow, elHptical ; length, about ^in. The dorsum 

 is elevated in a conspicuous longitudinal ridge. Form Le- 

 canid ; abdominal cleft and lobes normal, setae moderate.
