Supplementary Report on Insects Affecting the Strawberry. 235 



Ten of these species devour the root and crown of the plant, all Coleoptera 

 but one, which is the larva of a moth. The leaf and its petiole arc attacked 

 by two of the Hymenoptera, by all the Lepidoptera except two, by eight of 

 the Coleoptera, by both of the Orthoptera, by five of the Hemiptera, and by 

 the red mite. The flower and fruit are damaged by the ant, the stalk-borer, 

 one of the leaf-rollers, by a snout beetle, by two plant bugs, and by the 

 myriapod. 



Less than a fourth of the known enemies of the strawberry really seriously 

 injure it in a way to demand earnest effort for their suppression, the remain- 

 der being too few in number or too local in their occasional outbreaks, to do 

 more than threaten the crop with possible future mischief. Of these ene- 

 mies of the strawberry of the first class, but two devour the leaf — the straw- 

 berry slug and the leaf-roller ; four attack the roots— the white grubs and 

 the three root- worms ; one. bores the crown— the crown-borer ; and two in-, 

 jure the fruit — the tarnished and the dusky plant bugs. 



The Kose Slug {Selandria rosa', Harris). 



Order Hymenoptera. Family Tenthredinid^. 



This species is mentioned here only to call attention to the fact that it has 

 been reported by Mr. Townend Glover,* formerly United States Entomolo- 

 gist, to attack the strawberry when its ordinary food fails. 



The Brown Strawberry Span-Worm {Cymatophora pavipinaria, Pack.) 

 Order Lepidoptera. Family PHALiENiDj^. 



This species was found by me in midsummer so frequently, feeding upon 

 the leaves of the strawberry in Southern Illinois, as to make it worthy of 

 brief mention here. It is a slender, looping caterpillar, brown in general 

 color, about an inch in length, and gives origin to a gray moth which ex- 

 pands from three fourths of an inch to an inch, the wings being variously 

 lined and clouded with black. Specimens obtained August 1st, pupated on 

 the 11th of that month, and emerged on the 22d. Half-grown larv;e collect- 

 ed on the Gth of September, probably represented a second brood. 



The full-grown larva measured one inch in length, and was of a pale 

 yellowish green color, with a broad reddish brown stripe edged with black 

 on the back, and on each side of the fifth ring was a small black .spot. Seji- 

 tember 4th, after spinning a few threads over itself, it became a pupa, and 

 was transformed to a moth November 14th. 



Flea Beetles {Hfdticidiv.) 



It is not known thit these insects hive ever been severely injurious to the 



strawberry; but, as they are often very common upon these plants, and as 



some of them are exceedingly destructive to other vegetation, it seems wonli 



while to notice them here. They are easily distinguished by their swoUcm
