SYSTEMATIC TREATMENT 43 



I do not know that any notes on the male other than those in the original 

 description by Coquillet have ever been published and I have not seen the male 

 myself. However, it seems almost certain that the male described by Coquillet 

 really belongs with Puto yuccae (Coq.), a species that also occurs upon the white 

 sage, for this description applies throughout to a male of the latter genus. 



Pseudococcus cupressicolus n. sp.

In life. Living specimens have not been examined, but judging from 

 the morphology of the species the insect will bear a pair of slender caudal 

 tassels of perhaps one-half the length of the body, a series of much shorter 

 tassels along the lateral margins of the abdomen with perhaps two or 

 three very short pairs on the head. 



Morphological characteristics. Antennae 7-8-segmented, both num- 

 bers frequently appearing in the same individual. Not more than 11 

 pairs of cerarii present, these appearing in a quite definite arrangement 

 as follows : a pair on each abdominal segment, a pair opposite each ante- 

 rior spiracle and each anterior leg, an ocular pair and a pair anterior to 

 the eyes. There is a tendency for the cephalic and thoracic pairs to be 

 lacking and any of these pairs may at times be present on one side of the 

 body and not on the other. The cerarian spines are small in all except 

 the anal lobe pair, in which they are conspicuously larger. The anal lobe 

 cerarii include a circular cluster of many crowded pores which are not 

 surrounded by a chitinized area. Remaining cerarii with few pores, either 

 with or without two or three auxiliary setae, for the most part with but 

 two cerarian spines, but at times with three. No chitinization on the ven- 

 tral side of the anal lobes. Dorsal body setae numerous, very slender and 

 quite long. Tubular ducts not strikingly abundant, all small and without 

 a raised rim about the mouth. Anal lobe setae about equaling the anal 

 ring setae. 



Immature specimens differing from the adult in the reduction of the 

 number of pores in the anal cerarii and in a tendency for the cerarian 

 spines to be slender and elongated. 



Type host and locality. From Cupressus guadelupensis at Riverside, 

 Calif. A. F. Swain, collector. 



Hosts and distribution. From the type host and from Cupressus 

 irizonicus at Riverside. 



Notes: Morphologically this most nearly resembles P. ryani, but it may 

 readily be separated by the reduced number of cerarii, by the much more numerous 

 dorsal body setae and by the marked tendency toward the development of auxiliary 

 setae in connection with the cerarii.
