TENTH BBPORT OF THE STATE ENTOMOLOGIST 493 



Ground-Beetle. (Country Gentleman, for July 13, 1S93, Iviii, p. 

 540, c. 2 — 8 cm.) 



The grubs supposed to be killing watermelon plants by feeding on their 

 roots, at Cheviot, N. Y., are one of the Carahidce, possibly a Pterostichus. 

 It is quite improbable that their presence among the roots could have caused 

 the death of the vines, as they are carnivorous — living on other insects. 

 Amara obesa, also a carnivorous species, referred to. 



Although " worms" were sent in the bottle, only one larva was contained 

 in it when received. 



Insect on Wistaria. (Country Gentleman, for July 20, 1893^ 

 Iviii, p. 557, c. 2 — 17 cm.) 



An insect occurring in abundance on Wistaria, in Cheviot-on-Hudson, is 

 the two spotted tree-hopper, Enchenopa binotata (Say). It is described and 

 the appearance of its egg-covering given. Spraying the young larvae in 

 May or early June with kerosene emulsion would arrest the attack. Refer- 

 ences to articles on it. 



Maple-Tree Borer. (Country Gentleman, for July 20, 1893, 

 Iviii, p. 557, c, 1, 2 — 15 cm.) 



Glycobius speciusMS is identified, from Adams, N. Y. , and its principal 

 features and its serious injuries to maples given. A preventive is coating 

 the trunk of the tree with soft soap and carbolic acid to prevent deposit of 

 the eggs, and a remedy, cutting out the young larvae. 



Elm-leaf Beetle. (Country Gentleman for July 20, 1893, Iviii, 

 p. 558, c. 1 — S cm.) 



The beetle is identified from New Britain, Conn., and references given to the 

 principal articles upon it in the Country Oentleman for the past few years. 



"Water-Beetle. (Country Gentleman, for July 20, 1893, Iviii, p. 

 558, c. 2 — 9 cm.) 



Replying to inquiries from Geneva, N. Y., Dytiseus Harrisii (Kirby) is 

 identified, and its marked features given and itrf habits. The insect may be 

 harmful in feeding on the spawn of fishes and young fish. Its generic name 

 refers to its facility in diving. 



A Silk-Worm Moth. (Country Gentleman, for July 20, 1893, 

 Iviii, p. 558, c. 2, 3 — 12 cm.) 



A moth drawn to an electric light in Albany is Telea Polyphemus (Cramer). 

 From its large size it was named after the one-eyed giant, Cyclops, of my-^ 

 thology. Its cocoon is made of strong silk, but can not be reeled. Notice of 

 the unsuccessful experiment of M. Trouvelot in cultivating the caterpillar at 

 Medford, Mass., for utihzing the silk. In the notice of this experiment it 

 was named the " American silk-worm."
