NOTES ON LEPIDOPTEROUS LARV.

I. LEPIDOPTEROUS LARVA! WHICH BORE THE FLOWER-STALKS 
OF DASYLIRION. 
Several lepidopterous larvee were found May 18, 1892, in a 
dead flower stalk of Dasylirion wheeleri, on Tortuga Mountain, 
which is on the Mesa about five miles to the southeast of Las 
Cruces, New Mexico. The stalk containing these larve was an 
aborted one, which for some reason had died when it reached the 
length of a foot and a half, but had still become hard and woody. 
Probably the death of the stalk was caused by the larvz, which 
were found boring in tunnels inside its base, like coleopterous 
larvae. 
Description of Larva.—Vength, 30 to 42 mm.; width of meso- 
thoracic segment, 6% to nearly 7 mm. Whitish, nearly naked, 
elongate, widest anteriorly (on mesothoracic segment), with three 
pairs of quite well-developed thoracic legs, and five pairs of distinct 
but aborted and approximated prolegs. Head and dorsum of pro- 
thoracic segment corneous, ofa tawny brownish tinge; rest oflarva 
fleshy. Head about one-half width of mesothoracic segment, 
base retracted within prothoracic segment, sparsely hairy on
