PACKAKD.J ZOOLOGY MOTHS OF COLORADO. 551 



moths are of the color of pine- wood which has been long unpainted; 

 this may, however, be due to their state of preservation. 



C, sp. — Perhaps defensaria, but too much rubbed for identification, 

 occurred at Twin Lakes July 16-27, and in the mountains July 19, Sep- 

 tember 28 (Lieutenant Carpenter). 



G. femigata, Clerk.— One ^, Bear Creek, June 24 (Lieutenant Car- 

 penter). 



Phibalapteryx intestinata, Guen. — Colorado divide, June, 1 ? (Lieuten- 

 ant Carpenter). 



Hi/psipetes Galiforniata, Pack. — Kenosha House and Turkey Creek 

 junction, Colorado, June 18, 21 (Mead). Some fresher specimens than 

 those received from Mr. H. Edwards from California, are much paler; 

 the median band whitish ; the reddish band on each side very distinct ; 

 the hind-wings are almost whitish, with a faint diskal dot, and a faint 

 baud about half-way between the dot and the outer edge of the wing. 



Scotosia Meadii, Pack. (Eep. Peab. Acad. Sc, 1874).-— Near Turkey 

 Creek junction, Colorado, August 23 (Mead). This is structurally allied 

 to S. Calif orniata, Pack., but differs in the longer fore- wings, while the 

 scallops on the hind-wings are larger and shallower. 



Zerene catenaria, (Cramer), (Fig. 2). — Common at Plum Creek, Sep- 

 tember 22, 25. In coloration, the ten specimens collected by Lieutenant 

 Carpenter do not differ from eastern specimens ; but on comparing 

 them (5<^ -, 5 9) with fifteen (5 9 ; 10 5 ) specimens from Massachusetts, 

 I found that the wings of the Colorado moths were uniformly more 

 pointed toward the apex, the outer edge more oblique, and the wing 

 narrower than in the eastern examples. The fore-wing of the largest 

 Colorado moth measured 0.95 inch, and that of the Massachusetts speci- 

 men 0.90 inch, 



Aspilates quadrifasciaria, Pack. (Fig. 3). — This interesting form is not 

 known to inhabit Colorado, but lives in Kansas, whence I have received 

 it from Professor Glover, entomologist of the Agricultural Department, 

 at Washington, and Professor F. H. Snow, Lawrence, Kans. It is a 

 pure white moth, flecked with ochreous scales, with four slightly oblique 

 parallel bauds on the fore- wings. 



Flatcca Cal'iforniaria, H. Sch. {Gorytodes uncanaria, Gnen). — "Pike's 

 Peak" (A. R. Grote). 



Utiaspilates spi7iatoria,'P-dGk. (Fig. 4), (Kep. Peab. Acad. Sc, 1874). — 

 This very interesting form may be recognized by its pure white body 

 and wings, with peculiar pale-brown bauds on the anterior wings; also 

 by the full bulging head, the short palpi, and especially by the stout 

 spine at the base of the anterior tibise. I have received it from Mr. 

 Grote, from Colorado. It is very nearly allied to, and repeats the style 

 of markings and colors of Aspilates mundataria, Cr., which differs 

 generically from the other species of Aspilates. This latter species is 

 recorded in Staudinger's catalogue as occurring in Russia, Amur, and 

 the Altai Mountains. The occurrence of a representative species in the 

 mountains of Colorado is another interesting fact in the geographical 

 distribution 6f this family of moths. 



Fidonia acidaliata, Pack. (Kep, Peab. Acad. Sc, 1874). — This singular 

 form at first sight would be mistaken for an Acidalia, and differs from 

 the ordiu'ciry forms of Fidonia in the long, slender palpi and the very 

 slightly i)ectinated antennce. Mountains of Colorado, August 12-29 

 (Lieut. W. L. Carpenter). More numerous specimens were collected by 

 Mr. T. L. ]\Iea(l, August 7, at a locality twelve miles below Montezuma, 

 Colo., on Snake River, Middle Park, Pacific slope; elevation most likely 

 9,000 to 10,000 feet.
