the median and second lobes are narrower than those beyond second lobe. The 

 number of teeth is variable. Anal opening oval, .05 mm. from tip of median lobe. 

 Paragenitals in hve groups ; caudolaterals 3-4 ; cephalo-laterals 7 ; median 4. Dorsal 

 pores prominent and very numerous. Longitudinal thickenings enclosing the vaginal 

 opening ; this opening about .1 mm. from the tip of median lobes. 



Male : Length (exclusive of caudal stylus) .57 mm.; caudal stylus .34 mm.; 

 breadth of thorax .34 mm.; color yellowish brown, the abdomen and tip pallid ; 

 probably yellower in tip. Compared with other Aspidioius males, it is remarkable 

 for the very robust thorax, which, as mounted in balsam, shows a median pale line, 

 and imperfect lateral ones. 



Very closely allied to A. densiflorcE Bremner, but distinguished by 

 the color of the scales and the broad second lobes. A. deusiflorce is 

 described as having the median group of circumgenital glands one or 

 none.

Pseudococcus juniper! (Ehrhorn). 



On Sai?iiia vionospcrma, Canon City, Colorado (E. Bethel). Not 

 quite typical, but evidently this species. New to Colorado. At 

 Canon City Mr. Bethel also collected Ceropiito calcitectus (CockereU) 

 on Agropyroii ; another addition to the Colorado fauna. 

 Chionaspis sassceri, new species. 



Scale of female : 1. 5 mm. long, expanding posteriorly, somewhat curved ; secre- 

 tion ashy gray, smooth, not dense ; ventral scale present. 



Adult female : Length .5 to .8 mm., breadth at widest point about one half 

 length. Body after boiling in KHO hyaline ; anal plate broader than long. Me- 

 dian lobes touching at base and widely spreading toward tip ; in some specimens, 

 however, the median lobes are more or less parallel ; tips of median lobes rounded ; 

 inner lobe of first lateral pair less than one half width of median lobe ; outer lobe of 

 first lateral pair very short and much smaller ; second pair of laterals represented by 

 an inner and outer lobe, the latter being small and indistinct. No median spine-like 

 plates; others I, 2, 2, 2, 5-6. Spines rather large. Anal opening about one fifth of 

 length of body from base ; about diameter of the median lobe. Paragenitals 13, 24-
