CLEAR-WING MOTHS OF FAMILY AEGERIIDAE 39 



rearing. Other species of Ceanothns growing as many-branched, hard- 

 wooded shrubs in hilly sections throughout California showed no evidence 

 of the borer's attacks. Williams considers mellinipcunis a common species. 

 I do not. It is poorly represented in collections. Examples in the United 

 States National Museum are as follows : One male, one female, Castella, 

 Shasta County, Calif., August 19, 1907 (Williams) ; one male, Santa 

 Cruz, Santa Cruz County, Calif., July 1904 (Williams) ; one male, 

 Lompoc, Santa Barbara County, Calif. (R. H. Beamerj ; one female, Cali- 

 fornia (Barnes collection) ; one male, artemisiae, Los Angeles County, 

 Calif. (Coquillett). 



RAMOSIA ARIZONENSIS (Beutenmuller) 



Plate 19, Figure 107 



Caea arizmiensis Beutenmuller, Can. Ent., vol. 48, p. 372, 1916.— McDunnough, 

 Check list of the Lepidoptera of Canada and the United States of America, pt. 2, 

 No. 8773, 1939. 



Male. — Antennae strongly clavate, posterior three-fourths orange-red, 

 terminal quarter blue-black, pectinations pale brown. Labial palpi orange, 

 black at the sides and tips. Head black, stiff-haired on top, black and 

 orange mixed. Collar yellow. Thorax black, patagia narrowly striped 

 with yellow and a posterior transverse band yellow, beneath a large yellow 

 patch in front of the wing base. Abdoinen shiny black, all segments, ex- 

 cept the third, ringed with yellow, most broadly so on the last three seg- 

 ments ; anal tuft flat, moderately fan-shaped, yellow, intermixed with black 

 in center on top. Legs with femora blue-black, posterior tibiae yellow, 

 black on inner side and broadly ringed at the lower spurs, tarsi orange. 

 Forewing opaque, except for small areas before and behind the large, 

 square discal mark, which is black edged with red outwardly; costa and 

 veins blue-black with scattered red scales ; a heavy shading of red between 

 the veins of the outer and inner margins extending to the wing base; 

 fringes sordid black ; beneath preeminently orange-red. Hindwing trans- 

 parent, veins black; discal mark, wing base and narrow margins red. 

 fringes sordid black. 



Female. — Much like the male. Labial palpi wholly yellow; forewing 

 with discal mark wholly red or only slightly touched with black, the trans- 

 parent areas heavily suffused with red and a heavy red line along the inner 

 margin to the wing base. The short, blunt anal tuft wholly yellow. 



Expanse : Male 24 to 26 mm., female 26 to 30 mm. 



Distribution. — Arizona; Durango, Colo. 



Type. — Female, in the United States National Museum. 



Remarks. — The available series of 16 examples, all captured and more 

 or less imperfect, suggests a close relationship to mellinipennis. Obvious 

 diiiferences, confined to coloration, are the more opaque forewings and the 

 orange-red antennae, except for three specimens from Durango, Colo.,
