INSECTS OP THE HONEY-LOCUST. 653 



lighter shade, which extends as far as the discal dots, of which there are two of jet- 

 black raised scales oil each angle of the cell, the lower oae being a little more remote 

 from the base of the wing. Outer line scarcely visible in most of the examples, of 

 the general color of the wing, dentate throughout its course, ami bordered ou each 

 side with a verj^ pale shade of brown, which is darker, and broadens ou the costa^ 

 A row of terminal black dots. The middle of the wing sparingly sprinkled with 

 black scales. Fringes concolorous with the wing. All the wings beneath, hind 

 wings above, and abdomen light brown. All the tibire and joints of the tarsi with 

 whitish. Expanse, 19 to 22"!™. 



Hahitat. — District of Columbia. Described from fifteen males and eleven females. 

 (C. H. Fernald.) 



Larva. — When full-grown, 16™™ in length, greenish yellow, with three longitudinal 

 brown stripes ou each side of the dorsal line, extending from the thoracic to the 

 anal plates, and alternating with narrow lemon-yellow stripes, the last one being on 

 the line of the spiracles. Head, thoracic and anal plates with more or less brown 

 marks and blotches. There is a great variation in these larvje in the intensity of 

 the brown markings, but they can readily be recognized by a black lunate spot on 

 the under side of the subdorsal tubercle of the third segment, behind the thoracic 

 plate. 



Pupa. — Length, 10™™ ; dark brovvn, rounded anteriorly ; posterior end with a small 

 spine ou each side, extending obliquely out and backward, the end curving back, 

 ward. In a line between these stand four fine hooks, much longer than the lateral 

 spines. Abdominal segments, except the last, covered with coarse punctures, except 

 on the posterior edge. Wing-covers reaching to the fourth abdominal segment. 



3. The ash-gray blister beetle. 

 Lytta ciiierea. 



This beetle, Mr. L. Bruner says, in Bulletin 13, Division of Entomol- 

 ogy, p. 34, "has been observed several localities in northern Nebraska 

 to entirely defoliate young hedges of honey-locust. Until the present 

 summer I have not observed this insect attacking the honey-locust 

 since the summer of 1876 or 1877. At that time a nursery of small 

 trees of this kind was entirely stripped of leaves by them, as were 

 also several larger ones standing alone." 



The following species also occur at times on this tree, which, so far 

 as I have observed it, is rather free from insect pests : 



Order Lepidoptera.
