THE CANADIAN ENTOMOLOGIST. 159 



tapering ; cremaster short, square at tip, flattened and firmly adhering to 

 the silken web. It appears to have been yellowish-green, a lateral pale 

 line on the abdomen, the antenna cases marked with pink. 



Described from alcoholic specimens collected by Mr. J. B. Lembert in 

 the High Sierras of California. Concerning the habits of this insect, Mr. 

 Lembert writes : — "July 27th, about nine or ten in the morning of the 

 third day of search; I discovered the food-plant of the hardy little mountain- 

 eer. His little queen fluttered into the grass on the meadows at the base 

 of Mt. Gibbs. When she had laid about five or six eggs, she flew on to 

 the dry moraine and sandy hills to eat flowers, and in the meantime 

 another took her place. The eggs were deposited on the low growing 

 huckleberry vine, which is lower than the grasses that it grows among, 

 affording protection to the eggs and larvae against the dews and frosts that 

 prevail at any day on the highland meadows. The males outnumber the 

 emales six to one, according to my catch, as the latter feed on the 

 flowers growing on the old moraines which rise up out of the meadows, 

 and only fly to the meadows to deposit their eggs. 



When the larvse get large they hide, and in the first stage they are 

 almost invisible. When ^ inch long they are semi-transparent ; when yi 

 inch, they get about the colour of a lightly bruised apple and worm-like, 

 without spines. They greatly resemble the withered huckleberry ruit. 

 The eggs when first laid are glistening white, then dull white, and finally 

 greenish. They hatch in six days." 



Ichthyura van, Fitch. 



Egg. — Hemispherical, flat below, the shell semi-transparent white. 

 Under the microscope it appears covered with small, slight depressions, 

 closely crowded together and forming obscure roundedly hexagonal 

 reticulations; diameter, .9 mm. Laid singly, or as many as seven together 

 on the under side of a leaf. The larva hatches by eating a piece off of 

 the vertex of the egg, which may remain attached to the shell like a 

 circular trap door. 



Third stage. — Head slightly bilobed, rounded, clypeus depressed, 

 hairy, especially on the lower part ; shining black throughout. Cervical 

 shield and anal plate blackish. Body vinous-brown, with a broad band 

 of sordid yellowish-white, absent on joints 5 and 12, and containing a
