"Larva.— Head round, vertically bilobed posteriorly, pale testaceous. Body 

 cylindrical, normal, green, a dull crimson dorsal line with a small oblique 

 subdorsal dash on joint 6 and a dash on joints 5 to 12; a white subdorsal line 

 from joint 2 posteriorly to 13 anteriorly and a broken subdorsal one the larger 

 anterior part on each segment oblique. Tubercles small, hairs single, i and ii 

 separate, iv and v approximate, v anterior and dorsal to iv. On thorax ia + 

 ib, iia + iib, iv + v, numerous fine, short, secondary hairs, shorter and easily 

 differentiated from the primary- ones, bulbous tipped. Hairs all white, not 

 long, inconspicuous. 



"The larva was found resting on the red fruit bract of Loniccra mvolu- 

 crata, and was not observd to feed, being matured and pupating immediately. 

 Apparently the larvae do not eat the leaves, but more probably the flowers. 

 Found at Pine Grove, Platte Canyon, altitude about 7000 feet." 



A number of pupa cases in the Barnes collection from Crater 

 Lake, Ore., show the following characters : Thorax slender, cylindri- 

 cal, obliquely truncate in front, with two low, dorsal ridges running 

 back from the head. These are more prominent on the angle of the 

 thorax, and at their posterior ends opposite ends of wing-cases, form 

 prominent leaf-like projections. They are continued on the remaining 

 abdominal segments by rows of low compressed tubercles, acutely 

 produced in front and less so behind. Below the spiracles is a short 

 ridge bearing two small setae on each segment. The sheaths of the 

 appendages are, of course, disarranged, but they show a rather long 

 projection beyond the thorax. The pupa cases are pale, with a reddish 

 tinge about the thorax. They are marked by longitudinal brown lines 

 on the abdomen and two oblique lateral lines on each side of the 

 thorax. We are unable to distinguish them from a European pupa- 

 case of cosmodactyla. 



We accept Meyrick's arrangement of the synonymy as far as 

 European names are concerned. There seems to be some doubt that 

 pimctidactvla is the oldest name, so we follow Hagen's dates for 

 Maworth's work. We found the type of monticola Grinnell, now in 

 the Southwest Museum, to be a very poor S specimen, scarcely rec- 

 ognizable in this difficult group, and at first referred it to marmaro- 

 dactyla Dyar. A study of the genitalia in situ showed us that it did 

 not belong there, and subsequent careful examination of the super- 

 ficial characters convinced us that it was this species.
