series less well spaced, and the smaller joints of the antennae 

 proportionately much shorter than are those in fasciata. It has 

 been suggested that this might be an extreme color phase of the 

 last but aside from the size and characters just given, we find that 

 as the specimens of fasciata get darker, the head, thorax and legs 

 share the increase in pigmentation along with the elytra. In 

 trilohatus, there is a very decided contrast between the clear 

 rufous color of the head, thorax and legs, and the deep blue uni- 

 colorous elytra. Fasciata lives upon various Ptinidae and pre- 

 sumably this species has similar habits. 



DENDROTETTIX QUERCUS RILEY, AT YAPHANK, LONG 



ISLAND, N. Y. 



By Wm. T. Davis, New Brighton, Staten Island, N. Y. 



On September 3, 1912, a single male Dendrotettix quercus was 

 collected at Yaphank, Long Island, N. Y. This is the first record 

 from the State of New York of this sometimes very destructive 

 grasshopper. 



The insect was first described, but without a scientific name, by 

 Lawrence Bruner, in Bulletin No. 13, U. S. Dept. of Agri., Div. of 

 Entomology, in his report for 1886, printed in 1887, wherein he 

 calls it "The Post Oak Locust of Washington County, Texas," 

 and tells how by reason of its great numbers it had completely 

 defoliated the trees of the forest. He also mentions the bright 

 colors of the insect, its gaudy appearance and tells of its activity 

 and shyness. 



The species was next mentioned as Dendrotettix quercus, but 

 withoiut description, by Dr. Riley at the meeting of the Washing- 

 ton Entomological Society, held June 2, 1887, when he stated that 

 he had reared it many years ago in Missouri through all of its 

 stages. He adds : " The peculiarity of the genus is that as far 

 as we know it is essentially tree-inhabiting." 



The scientific name and description were first assembled by Dr. 

 Packard who, in the Fifth Report of the U. S. Entomological
