78 Transactions. — Zoology. 



tion appeared in November of the same year. Circumstances 

 made it impossible for my paper to be printed before May, 

 1892, and in the technical sense of publication I suppose Mr. 

 Olliff has priority. Had he not attached my name to the 

 species nothing need now be said ; but, whilst quite appreciating 

 the honour thus done me, I must venture to ask whether the 

 proper name of the insect should not be Pulvinaria atriplicis ? 



Pulvinaria maskelli, Olliff, var. spinosior, var. nov. Plate 



IV., figs. 6, 7. 



Insects forming a white, cylindrical, narrow ovisac, which 

 sometimes attains a length of ^in., with a width of scarcely 

 ^in. This ovisac is very finely striated or corrugated trans- 

 versely. 



Adult female dark-brown or red-brown, placed at one end 

 of the ovisac and raised up a tcrgo. The normal form before, 

 gestation is elliptical, and the length about ^in. to jin., but at 

 gestation it becomes much shrivelled and wrinkled, and there- 

 fore considerably smaller. The median dorsal region is some- 

 what convex, the margins a little flattened. Antennse of eight 

 joints, of which the third is much the longest, the sixth 

 seventh and eighth the shortest and subequal. There is a 

 longish hair on each of the first and second joints, and several 

 shorter ones on the others, especially on the eighth. Feet 

 rather strong, with several hairs on each joint ; tarsal digitules 

 long knobbed hairs, digitules of the claw very widely dilated. 

 Epidermis bearing many small slender tubular spinnerets. 

 On the margin of the body there is a row of conspicuous, 

 rather thick, longish spines, and these may sometimes in life 

 be seen to bear short waxy tubes. Abdominal cleft and lobes 

 normal. Mentum apparently monomerous; rostral setae short. 



Second stage not observed. 



Larva red, flattish, elliptical, slightly tapering posteriorly, 

 active : length about -^^va. Antennae of six subequal joints, 

 the sixth bearing several hairs, of which one is very long. 

 Feet slender : the digitules are all fine hairs. Abdominal cleft 

 and lobes normal, terminal setae very long: between the lobes 

 is in life a short pencil of white cotton on short hairs, and on 

 being slightly pressed the abdominal extremity protrudes in a 

 circular reticulated form. On the margin of the body is a row 

 of short conical spines : the four spiracular spines are rather 

 long. 



Male unknown. 



Hab. In Australia, on Frenela (Callitris) rohiista, the 

 "Murray Pine." My specimens were sent by Mr. French, 

 who received them from Mrs. A. Molineaux, of Adelaide, but 

 the exact locality was not named. The tree is a native of 

 South Australia.
