THE CANADIAN ENTOMOLOGIST. 415 



Many of the winter homes of the larvce were examined, and in all ihe 

 larva was found with the head towards the plant. On May i8th, which 

 was the third warm spring day at Ottawa since about the middle of April, 

 when we had two such days, I noticed that some of the larvae had re,vived, 

 eaten their way down through the bottom of their winter case, and were 

 feeding on the nearest green leaves. The whole inside surface of a leaf 

 was eaten, after which the larva attacked other leaves in the same way. 

 During this period a considerable quantity of white silk was spun just 

 beneath but touching the winter home. A few of the leaves were 

 gathered together by the silk. 



On June 19 some larv?e were still found by Mr. Kearfott and the 

 writer, and one living pupa in the winter case. At this time it was 

 difficult to see the work of the larvfe on account of the new growth of the 

 plants. 



Larvae collected at the end of April all pupated in their winter 



quarters, and no fresh food was put in the jar. Moths began to emerge 



about the middle of June, and continued to issue for a few days. From 

 other material collected later, the moths appeared on June 29 and July 6. 



The mature larva is 5.5 mm. long at rest. The head is honey- 

 yellow, shining, slightly bilobed, rather flattened in front ; clypeus 

 reaching two-thirds to vertex ; mouth-parts and margins of clypeus tinged 

 with lake-red ; ocelli black ; antenna? short and pale, hairs on face pale. 

 Thoracic shield concolorous with head, shining, wider than head. Body 

 without markings, cylindrical, segments rather deeply divided, colour 

 pale orange, venter paler tlian dorsum. Tubercles shining, large for size 

 of larva, but inconspicuous, only slightly darker than body. Setie slender, 

 pale, one hair from each tubercle, anal shield honey-yellow, shining, all 

 the feet whitish ; thoracic feet bearing black plates. 



The species is single-brooded. 



Hylotoma spiculata. — A Correction. — In the description of this 

 species on page 30S of this magazine, the locality is given as Oak Creek 

 Canon, New Mexico. I am indebted to Prof. T. D. A. Cockerell for 

 pointing out that this should have read Oak Creek Canon, Arizona.
