Japanese spotted camel cricket (Diestrammena japon- 

 ica Blatchl.). This interesting species was found in New York 

 State for the first time in 1916, when it occurred in large numbers 

 in the cellar of a Buffalo greenhouse. A few specimens were 

 received October 24, 192 1 from Henry W. Thorne, Johnstown, 

 accompanied by the statement that it occurred in several cellars 

 in his vicinity. This latest record would indicate that the insect 

 is becoming somewhat widely distributed in the country, presumably 

 through shipment of greenhouse plants, especially as it has been 

 recorded previously from Massachusetts, Ohio, Illinois, iRhode 

 Island, Wisconsin and Canadian greenhouses. 



This camel cricket has a body length of about one-half of an 

 inch, while the distance from the tip of the slender antennae to the 

 extremity of the extended hind leg is 2^ to 3 inches. It was earlier 

 identified asD. marmorata Haan. but has since been referred 

 to the above-mentioned species. A brief account of this insect is 

 given in the 32d Report of this office (N. Y. State Museum Bulletin 

 198, page 88). 



Camel crickets are nocturnal in habit and in nature are usually 

 found under logs and stones, along streams or in moist woodlands. 

 Occasionally they occur in cellars. They are recorded as having 

 nearly omnivorous habits, readily eating meat, fruit and vegetables. 

 There is little probability of appreciable injury following an infesta- 

 tion by this insect.
