then changes to pupa. The cocoon itself is very slight, and is merely a 

 web or covering of slender threads of white silk. 



Pupa. — Length, 8.75 mm.; width at widest part, 2 mm. The wing- 

 cases and thorax are shiny black, lightly chased with vermiform lines. 

 The abdomen is dull black, and finely shagreened, the segments trans- 

 versely wrinkled on dorsum; the folds between the segments are ochrace- 

 ous. On the thorax are 10 rather long, stiff, blunt, rust-red bristles, 

 carving forward, 5 on each side, and along the dorsum are 2 series of 

 conspicuous black warts, 1 on each side, each bearing a single, long, 

 rusty, twisted hair, which first slopes forward and then swings towards the 

 centre of dorsum, and backwards for y^ of its length. The spiracles are 

 black, and just above them is a row of small, black, piliferous warts, each 

 with a single, thin, short hair. The cremaster is prominent, of a dull red 

 colour, edged with black, and terminates in a bunch of 8 rust-red bristles, 

 4 on each side, which converge and cross at their tips, forming an arch. 

 In one specimen the two posterior segments were the same colour as the 

 cremaster. 



The length of the pupal state of these specimens was the same as 

 that of those moths bred from mature larv?e in, and previous to, Novem- 

 ber, 1900, viz., 17 to 20 days. 



TWO NEW SPECIES OF PULVINARIA. 



BY GEORGE B. KING, LAWRENCE, MASS. 



Pulvinaria Hunteri, n. sp. — Old, dried and wrinkled female scales, 

 cream-colour, more or less mottled with patches of red-brown, and the 

 outer margin practically red brown. Ovisac clear white, texture as in 

 innumerabilis, and not so large. The size of the scale, cleared and spread 

 under cover class, practically hemispherical, is from 6 to 7 mm. in 

 diameter. The texture of the scale is quite thin and requires little boiling 

 in caustic potash to make it very clear and colourless. The following 

 measurements of antennal segments are in micromillimetres :

Joint 3 is longest, 4 next; there is little difference in the length of 1, 

 2 and 8, and 5, 6 and 7 are nearly equal in length. The first joint has 3
