590 BULLETIN UNITED STATES GEOLOGICAL SURVEY. [FoZ.VI. 



These were pinkisli compared witli tlie larvae I found in June beneath, 

 the gummy mass of exuded sap, and which pupated in July. I could 

 not carry the winter larvae through, hut they are undoubtedly the same 

 si^ecies. Professor Kellicott, I believe, at first doubted this, but after- 

 wards came to my original opinion. The species is, then, single brooded. 

 It is very destructive and spreads in nurseries among imiDorted pines. 

 As it affects the branches and is protected by the gum, I do not think 

 that anything can be done except digging the larvse out with the knife, 

 which is tedious and, except under peculiar circumstances, an unprofit- 

 able and difficult process. 



LAEYJE AFFECTING THE HICKORY. 



Phycis caryae Grote, Papilio I, 13. 



This species was discovered by Mr. Coquillett, of 111. The larva 

 burrows into the branches of the pignut hickory, Garya ]^orcma. "The 

 larva spins a thin web around the footstalks of the leaves which grow 

 near the terminal end of the branch, and then burrows into the termi- 

 nal bud and wood of the first year's growth." 



Phycis angusella Grote, Nortli Am. Eutomologist I, 51. 



Tliis species has been reared from larvae boring into the leaf-stems of 

 the hickory on Long Island by Mr. Akhurst. The specimens of the 

 moth which I have examined proved to be all males. It may be known 

 by the continuous black dash on the under side of hind wings along costa. 

 I use tbe typical generic term Fliycis of Haworth for the species for- 

 merly separated under Acrohasis. 



Phycis demotella Grote, Papilio I, 14. 



This moth, of which I only know the male, and not as yet the larva, 

 has a shorter black mark on secondaries beneath, not connected with 

 base of Ming, and a narrow streak on median vein. Head and thorax 

 j)inldsh white, as also base of wings. Taken with angusella at West 

 Farms by Mr. James Angus. I thiuk the larvae feeds on Hickory. 



LARVA AFFECTING THE LOCUST. 



Salebria contatella Grote. 



This Sliecies was bred from larvae found on Robinia pseudacacia, in 

 the Department of Agriculture grounds at Washington. It draws the 

 leaves together, the side of one to that of another, according to Profes- 

 sor Comstock, in whose valuable report for l&SO an account of the in- 

 sect will be found, p. 2G1, et seq. The variety 5-punctella was also bred 

 from the same larvae. This variety seems to arise, as I have stated, by 

 the outer line of the t. a. line, becoming resolved into dots. My figure, 

 in the Am. Ent., is the least exact on the plate, the figures on which, 

 otherwise, were accurately transferred to the stone and finely engraved 

 upon it.
