hair. Carinae entire. Pronotal punctures equal in size throughout tlie disk, male 

 modifications at the middle of the first ventral segment generally pronounced. 

 Pronotal punctures very small and sparse tlirougliout; male with a tubercle in the 

 middle near the apical margin of the first ventral, the coloration (as stated above) 

 of pronotum diflferent in the two sexes, tlie male having a small transverse black 

 spot at the middh' of the basal margin, the female having the somite black, with 

 pale apical angles and fine apical margin (See Fig. lfj6B). Legs brown or blackish 

 througliout. Abdominal lines arcuate throughout, curving forward externally. 

 Plates entire, tile bounding arc extending to the basal margin of the first segment; 

 presternum rather narrow and convex between the coxs, with two strong and well 

 developed carina?, which are but rarely abbreviated in front. (After Casey on 

 Sci/mntis margiiiicollis Mann.) This insect was found to abound along the Pacific 

 Coast from Humboldt County to San Diego, and was introduced into this state by 

 Mr. Koebele, but it w.as found to have existed here before his introduction. It is 

 predaceous on San Jose Scale (Aspidiutus perniciosus), Red Scale (Chrysom- 

 phalus aurantii), Yellow Scale {Chrysomphalus citrinus) , Ivy Scale {Aspidiotus 

 hederae), Oleander Scale (Aspidiotus nerii Bouche at Melbourne) and Mealy 

 Bugs (Pseudococcus citri — Citrus Mealy Bug, and Pseudococcus adonidum — Long- 

 Tailed Mealy Bug). It has also been reported as feeding upon Purple Scale 

 (Lepidosaphes heckii) at San Diego. I believe that the greatest good comes from 

 its work on Red Scale. Last fall I had an opportunity to visit certain orchards in 

 Orange County with Commissioner Roy K. Bishop and he showed me countless 

 numbers of the larvae of this insect feeding on Red Scale and apparently doing 

 much good work. 



In Ventura County, we have very little red, yellow, or purple scale, so it is 

 impossible to find R. lopanthae extensively, excepting in the orchards infested with 

 the Citrus Mealy Bug. It is doubtful if any material good is done by it in holding 

 this pest in check. The larvse are light brown in color, slightly longer than the 

 adult and are easily recognized by a light yellow, oblong blotch on the dorsum. 



Hyperaspis lateralis Mulsant 

 (Figure 166 A. Male) 



Length .2 mm. to 3.0 mm., with 2.15 mm. to 2.4 mm. E'orm very short and 

 broad with body broadly rounded and strongly convex. Head of male light, while 

 black in female. Pronotum of male dark with lateral margins and fine apical 

 margin light as shown in cut. Pronotum of female dark throughout. Eyes black. 

 Elytra shiny black, punctures sparse and fine, but distinct. There are three red 

 or pale spots on each as follows : Long and narrow spot on the margin at the 

 humeral angle, a sub-marginal or oval rounded spot near the apex, another on the 

 dorsum near the middle, and near the inner third of the width. The long humeral 

 spot, or vitta, extends to the middle of the elytra. Legs black. 



This insect is a native of the southwestern portion of the United States and has 

 been found in California, Arizona, New Mexico and Texas. It feeds almost 

 entirely upon the mealy bugs and has been reported from New Mexico as feeding 

 on Phenacoccus helianthi by J. D. Tinsley. In California it has been found
