works. According to European writers, the larva has been reared from 
a case on seeds of Artemisia, but this is sonewhat unsatisfactory, as 
there is some doubt as to the exact nature of the larval food. 
The larval case is not unlike that of the clothes moth, Tinea pellio- 
nella. It measures, when completed, from 8 to 11 ™™ in length and 2 to 
3™™" in breadth, being about four times as long as wide. It is about 
half as thick as wide, and the sides are nearly parallel, the narrowest 
portion being usually at the mouth or place of exit and the widest near 
the middle. It is dirty dark gray in color and is composed of fine par- 
ticles of dust and such other material as naturally accumulates in the 
corners of a room, joined together with silken webbing and sparsely 
interspersed with larval excremental pellets. 
When at rest on the walls or elsewhere in rooms, and still more 
when in flight, it is not without close examination that this species 
can be distinguished from its cousins, the clothes moths, 7. pellionella 
and 7. biselliella, and it often pays the penalty for this resemblance 
when it ventures within the vision of the wrathful housewife. The 
mounted moth, however, is not liable to be mistaken by an entomologist 
for any other indoor species. It is about the same size as the common 
clothes moth, Tineola biselliella, exhibiting the same variation in size. 
It may be recognized by the fore-wings, which are nearly covered with 
blackish scales, except a broad, yellowish dorsal streak and a conspic- 
uous subhyaline median discal spot. 
In addition to the material captured and reared in the District of 
Columbia there are specimens in the National collection from Kirk- 
wood, Mo., Wyandotte Cave, Kentucky, and California—evidence of a 
wide distribution in this country. It is a true cosmopolite, and to be 
found almost everywhere. Abroad it is known in central and south- 
ern Europe, Great Britain and Ireland, Asia Minor, North Africa, 
Australia, and New Zealand. 
European systematists place this species in the genus Monopis, 
Huebn.—|F’. H. C.| 
ANOTHER MOTH LIKELY TO BE MISTAKEN FOR TINEA GRANELLA. 
To the list of moths of the genus Tinea enumerated in Bulletin No. 
8, n. 8. (p. 35), as liable to be mistaken for Tinea granella Linn., the 
European grain moth, 7. misella Zell, should be added. Of this spe- 
cies Mr. C. S. Gregson is quoted in the Entomologist’s Annual for 1857 
(p. 121) as follows: “I have bred it from unthrashed wheat this year; 
it made up in the head and fed upon the grain. I formerly bred it 
from the interior of bean stalks, for, seeing the pupa cases projecting 
from the stalks, I split up several stems and so found the larva.”—
