ART. 7 REVISION OF COCCOPHAGUS — COMPEEE 67 



of abdomen. Abdomen broadly rounded at apex. Ovipositor short 

 and not exserted. 



Fore wings hyaline, densely and closely ciliated, with a very 

 short marginal fringe. Submarginal vein one-fourth longer than 

 marginal; postmarginal absent. Stigmal vein not enlarged at apex 

 nor much constricted at base, as shown in Figure 89. 



Basitarsus of middle legs about as long as the three succeeding 

 joints united; tibial spur slightly shorter than basitarsus. 



Scutellum with three pairs of bristles and from five to thirteen 

 small setae scattered in proximity to anterior pair of bristles. Pro- 

 notum and mesoscutum with numerous small, black setae. Each 

 parapsis with four setae and each axilla with two setae, these being 

 about as large as those scattered on scutellum. Metanotum, on 

 either side, with two small setae set in punctures on anterior margin. 

 Propodeum with small setae scattered on sides. Sides of second, 

 third, and fourth tergites with a few small, dark setae in transverse 

 alignment ; fifth and sixth with the rows of setae complete across 

 dorsum ; seventh tergite with a median semicircle of setae and a few 

 scattered, stronger ones. 



Blackened portions of mesoscutum, axillae, and scutellum with 

 areolate reticulations. Metanotum on either side with four wavy 

 striations. Propodeum with two strong, sublateral carinae a short 

 distance mesad of spiracles. 



Length 0.9 mm. 



Male. — Aside from sexual differences, the males differ from the 

 females mostly in coloration. Body black, except for tegulae, a 

 large part of parapsides and a spot on pleura close to root of fore 

 wings which are yellowish. Tegulae sometimes marked with a 

 black dot. Face and legs, except a greater part of hind tibiae bright 

 yellow. Eyes a trifle smaller than in female, so that antennae are 

 inserted about midway between oral margin and basal orbital line. 

 Abdomen shorter than thorax. 



Redescription based on the original description and additional 

 specimens reared from Saissetia oleae received from South Africa. 

 According to Rust C. trifasciatxis is the most effective black scale 

 parasite occurring in South Africa. Attempts were made to estab- 

 lish this species in California, and it was at least temporarily estab- 

 lished, as specimens were reared from scales collected in California. 



37. COCCOPHAGUS LUTESCENS. new species 



A small species, yellow to pale white. Tibial spur of middle 

 legs a trifle longer than the basitarsus; basitarsus as long as the 

 succeeding two joints united. 



Femiale. — General color pale yellow on the dorsum, fading to 

 white on the sides and venter of thorax and on the face and cheeks.
