PSYCHE.

ate, normal, not elongate; black, not shining, 

 marked in white as before, the lines all nar- 

 row, dotted, somewhat broken ; joint 12 a 

 little enlarged, the addorsal line widened on 

 it ; anal feet projecting laterally'. No shields ; 

 tubercles and setae obscure, their bases a 

 little enlarged, making the surface of the 

 body somewhat irregular ; traces of a sub- 

 dorsal line ; abdominal feet pale dotted out- 

 wardly. 



Stage IV.— Mead dull black, white dotted, 

 the upper faces of the lobes nearly solidly 

 black, but many dots across clypeus in two 

 transverse bands ; width i.i mm. Body dull 

 black with fine, broken, addorsal and more 

 continuous but narrow substigmatal white 

 lines ; traces of the other lines as dottings. 

 Tubercles small, slightly elevated; setae 

 short ; black. Cervical shield, anal plate 

 and feet slightly brownish diluted ; no corn- 

 ified shields. Segments wrinkly subannu- 

 late. 



Stage V. — Head broad, erect, roundedly 

 bilobed ; sordid white in ground color, a 



black band on the vertex, one across apex of 

 clypeus, broken, one above mouth, irregular 

 and with dots between ; vv'idth 1.5 to i.S m;n. 

 Body smooth, rather robust, normal, not 

 elongate ; setae and tubercles minute except 

 tubercle ii of joint 12 which is elevated. 

 Color variable. Dark gray, finely lined. 

 Thoracic feet red-brown or black. Body 

 lines addorsal, subdorsal, lateral and stigma- 

 tal, the addorsal ones enclosing black spots, 

 or a continuous black space or broken up by- 

 red and white dots. Ground color dark 

 purplish shaded with black laterally and sub- 

 ventrally and with reddish stigmatally ; a 

 dark swelling behind the spiracle; substig- 

 matal line usually yellow, narrow, distinct ; 

 other lines more or less broken and dotted ; 

 all the surface finely dotted and mottled. 

 Feet sometimes reddish. 



The larvae entered the earth Mav 24th and 

 emerged the following March. Eggs were 

 obtained which hatched March 24th and the 

 larvae matured again before the end of May. 



CocciDAE AND Ai.EURODiDAE. — Two pa- 

 pers, embodying contributions to our knowl- 

 edge of the Coccidae and Aleurodidae, have 

 just been completed in the laboratory of en- 

 tomology at Stanford University. The pa- 

 pers are of such size that some time must 

 elapse before their publication, so that an 

 immediate brief statement of their contents 

 will probably be of interest to entomologists. 

 "Coccidae of Coniferae" is the title of a paper 

 by Geo. A. Coleman, based on material col- 

 lected by the author in the summer of 1901, 

 in the course of a trip on foot and horseback 

 of a thousand miles through the great con- 

 iferous forests of Northern California. This 

 expedition was made for the express purpose 

 of gathering specimens and notes for a study 

 of the conifer-infesting scale insects. Mr. 

 Coleman collected 22 species of Coccidae 

 from 26 species of conifers, ten of the species 



being described as new. Of these ten, im- 

 mature stages of four are described, and the 

 complete life history of one. The paper also 

 includes a compiled list of the Coccidae re- 

 corded from the Coniferae of the world, and 

 a host list with distribution. There are in- 

 cluded also notes on the economic status of 

 the conifer-infesting scales. 



"Aleurodidae of California" is a paper by 

 Mrs. Florence E. Dorsey which describes 

 twenty new species of aleurodids found in 

 California, thus increasing the number of 

 known N. A. species in this family from 40 

 to 60. In the case of every one of these 20 

 new species the immature stages have been 

 studied by the author and are described in 

 detail. It is unnecessary to say that these 

 accounts of the post-embryonic life history 

 of so many aleurodid species constitute a 

 really important contribution to our knowl-
