hind thighs, which give some of them a power of leaping scarcelj' exceeded 

 by the flea itself. 



Three species, all minute, are known to infest the strawberry: the notori- 

 ous cabbage flea beetle (Phi/llotreta vittaia), and two others not heretofore 

 reported as injurious to this fruit, Crcpidulera fuscida and Sfistena blanda. 



Tlie first may be distinguished by its smooth and shining surface, black, 

 with two broad, irregular, yellow stripes on the wing covers. 



Crepiikdei'nfuscula is of about the same size as the cabbage flea beetle, but 

 shorter and thicker. It is black throughout, except the antennfe and tarsi, 

 which are red : and the elytra are covered with a conspicuous coat of gray 

 pubescence. The thorax is coarsely punctured, and marked with a trans- 

 verse impression before the basal margin. 



Si/stena blanda, already known as injurious to corn, wjis especially abundant 

 on the leaves of the strawberry near Anna, in Southern Illinois, where it was 

 certainly feeding upon that plant, as I have demonstrated by dissection. It 

 may be easily distinguished from the other flea beetles by its elongate form, 

 and by if« ochre-yellow color, w^ith a broad pale stripe on the middle of each 

 wing-cover. The punctures on the latter are irregularly distributed, instead 

 of being arranged in rows, <vs in the other species. 



Although Phi/llotreta vittaia was abundant on cabbages in Southern Illinois 

 in the spring of 1883, 1 did not notice it on strawberries adjacent, and I doubt 

 if it is likely to require the especial attention of the strawberry grower. 



The Strawberry Leaf Beetles. 



{Puria at€rrii)ia,Yia\i\.; Scekdonta nfbidosus,hec.; Cdaspis brunnea,Yah.; Co- 



la.spis tristis, Oliv.)- 



The three species first mentioned are tho adult beetles of the root-worms 

 of the strawberry, and will be fully described and figured on another page. 

 They are mentioned here to call attention to the fact that they all feed— at 

 least for a time after emerging from the earth — upon the leaves of the straw- 

 berry plant, one of them {Paria aterrimi) occasionally doing conspicuous 

 mischief. As this last species has the longest adult life of any of the root- 

 worms, it is the most likely to do harm as a leaf beetle, and is, in fact, the only 

 one the injuries of which have attracted attention hitherto. If these beetles 

 should become abundant enough to require remedial measures, poisoning 

 with Piri.s green and other suitable stibstances, as recommended in the dis- 

 cussion of these insects given under tlie head of strawberry root-worms, 

 will be the most suitable remedy. 



The OiJMcit'E-BAXDED Leaf-Roller {Cacicria rosaceana, Harris). 

 Order LEi'iDorTERA. Family Tortricid;i?. 

 This leaf roller of the apple has been several times reported to transfer 

 its alter)tion8, at least occasion illy, to the strawberry. In his " Guide to the 

 Study of Insects," Dr. Packard says of this species: " We found, on the 2.'U 

 of .Iimcthc fully grown larva on tiie leaves of the strawberry, doubling them 

 up nnd binding them together by a few silken threads.
