THE ALFALFA LOOPER IN PACIFIC NORTHWEST. 1138 
Fifth instar (fig. 45).—Body dark olive-green, dorsal edge of stigmatal line 
opposed by an almost black line which fades into the general body color dorsally ; 
head brilliant green, mandibles and palpi brown, a black oblong patch on 
posterior margin of eye extending from near median line almost to base of 
mandibles; thoracic legs almost black. ‘Length, 21 mm. to 28 mm. 
THE PUPA. 
(Pl. XI, fig. 4.) 
“Pupa depressed somewhat above the wing cases at back of the thorax, the 
eyes prominent, the tongue case projecting below the wing cases, forming a round 
prominence over the first abdominal segment. The cremaster is short and blunt, 
and the hooks with which it is furnished are fastened in the silk of the cocoon. 
Wing cases slightly creased. Color brownish-black, but paler at the joinings of 
the parts and between the abdominal joints. In occasional instances the whole 
pupa is pale.” 
The above description of the larval stages of this moth agrees in 
substance with that published by Dr. H. G. Dyar?* for this species 
in California. The larve, however, are not constant in the matter 
of coloration. Adult 
larve were found with- 
out the characteristic 
black markings, while 
others had the entire 
head black. Some 
larve were of the same 
pale-green color in the 
fifth instar as in the 
fourth, while others 
were almost white. Fic. 45.—The alfalfa looper (Autographa gamma cali- 
fornica): a, Larva, dorsal aspect; b, same, lateral 
That we had the first aspect. Enlarged 23 diameters. (Original.) 

instar is only an as- : 
sumption from the number of subsequent molts obtained. Dr. Dyar’s 
description of the pupa is used, as it agrees identically with those 
found in the Northwest. The pupa is dark olive-green, with brown 
shadings and pale intersegmental bands when first formed, but soon 
becomes uniformly brown. 
THE ADULT.?

The following is a translation of Speyer’s original description: 
Two California males from Moschler’s collections differ from the European 
gamma (which I can, however, only compare with native specimens) in the fol- 
lowing points: The color of the dorsal surface of the forewiugs is a clear, 
light-blue gray, except the punctuation which is rose colored or rust colored; 
this is exhibited in all the gamma found here by me, and also in several dis- 
tinet variations.
