8. Carneades brunneigera Grote. 



Head 2.7 mm., roughly shagreened, dark brown, a pale space above the 

 eyes on the side of each lobe; no reticulations. Body dull, sordid brown, 

 the skin somewhat translucent. Cervical shield brown; markings obso 

 lete ; the pale dorsal line can be made out the whole length edged with a 

 dark shade that is contracted at incisures; also a dark shade at position 

 of subdorsal line, leaving a pale space widening at incisures as in F. van- 

 couvcmisis. Spiracles black ; tubercles in cornified areas; setae minute. 



Food plant not stated. Placer Co., Cal. A. Koebele, No. 141. Very 

 similar to F. vancouverensis, but paler, more translucent, and the head 

 roughened. 



9. Carneades perexcellens Grote. 



Head 3 mm , reddish-brown, shining; faintly marked by pale reticula 

 tions Cervical shield shining brown, slightly cornified. Body sordid 

 brown, somewhat translucent as in C. brunneigera, and similarlv marked. 

 Dorsal space broadly pale, nearly obscuring the pale dorsal line, this pale 

 area only slightly widening at the incisures, and reaching almost to the 

 faintly traceable, narrow, pale subdorsal line. Substigmatal line faintly 

 shadowed, whitish, concolorous with the pale subventral area. Spiracles 

 black; tubercles cornified ; setae minute. 



Food plant not stated. Alameda, Cal. A. Koebele, No. 582. Closely 

 similar to C. brunneigera, but the head is not roughened 



10. Carneades divergens Walker. 



Head 2.9 mm., shining brown, the dark curved vertical shade distinct 

 above and near the median suture; reticulations pale, obscure, dividing 

 the sides into rounded dark spots. Cervical shield brown, darker before

Food plant not stated. Placer Co., Cal. A. Koebele, No. 267. Simi

Head 2.5 mm., shining dark brown, reticulate with a still darker tint, 

 the curved vertical band black, distinct above and below; ocellar line nar

 dorsal and subdorsal pale lines. Body reddish-brown, finely marbled, 

 somewhat paler below the spiracles. Two broad blackish shaded bands, 

 the dorsal composed of segmentary diamond-shaped marks, faintly divided 

 by the obscure dorsal line (as in Carneades, but less rounded); the lateral 

 filling in the space between the subdorsal and substigmatal lines, or re-
