probably confounded this species, as well as C. fragilis, with C. califor- 

 nica in the 5th report of the U. S. entomological commission.

Larva. — Head black, very hairy except where the occelli are, some- 

 times tinged with powdery blue in front ; labrum whitish. Body entirely 

 black, except the tips of the abdominal feet, which are pale, covered 

 with long, fulvous hair, quite thick, especially dorsally, where it is 

 keeled, and laterally, where it is tufted anteriorly on the segments. 

 Almost entirely without marks ; some have an irregular red sub- 

 dorsal line, interrupted between the segments and narrowly cen- 

 trally on each segment, mottled with the ground colour ; while all 

 have a series of subdorsal small blue dots below the red line, only one 

 on each segment, and sometimes a lateral series of red dashes. In some 

 even the blue dots are obscure and wanting on the central segments. 



Food-plants. — Oaks ( Quercus agrifolia and Q. lobata). 



Habitat. — The coast region of California. 



Dr. Packard has confounded C. fragilis with this species, if not others 

 also, and consequently gives it a habitat much too extended. C. fragilis 

 is abundantly distinct from C. californica in the larva, and, though the £ 

 moth is very similar, the $ shows good specific differences. 



Clisiocampa fragilis, Stretch. 



1 88 1 — Stretch, Papilio, i., 64. 



1888 — Hy. Edw., Ent. Amer., iv., 62. 



1890 — Packard, 5th Rept. U. S. Ent. Com., 120 (as C. californica.) 



Larva. — Head blue gray, dotted with black, mouth and ends of 

 antennae black, labrum and bases of antennae sordid white. Body with 

 the ground colour black, a broad pale blue dorsal band, broken at the seg- 

 mental incisures and narrowed a little at both ends of each segment, 

 absent on joints 2 and 13. Orange subdorsal marks much reduced, 

 scarcely noticeable, consisting of from one to three narrowly linear, 

 waved and broken streaks. Subdorsal blue dots, two on each segment, 

 very large, subquadrate, either separate or confluent on their upper sides,
