466 Report of the Department of Entomology of the 



A hint as to the true nature of niveus was given in a letter to the 

 editor of the Canadian Entomologist in 1886 from E. W. Allis 5 of 

 Michigan who states that he has " taken niveus entirely about 

 apple and hardwood, and fasciatus (nigricornis) about raspberries 

 and certain woody weeds. They are more common than niveus 

 here and very distinct." Packard 6 describes the insect as " boring 

 into the corky bark of the elm in the southern states, inserting 

 its eggs irregularly, not in a regular series as when it oviposits in 

 blackberry, raspberry and grape." As regards the elm, the eggs 

 were probably those of niveus, while in case of the latter plants the 

 oviposition was unquestionably by nigricornis. Within recent 

 years these crickets have been more closely studied by a number 

 of workers, notably Houghton 7 of Delaware, whose work, with our 

 own, has no longer left any doubt as to the true character of the 

 egg-laying habits of the two species. 



distribution. 



This species ranges all over the State of New York with the 

 exception of forested regions in the northeastern part. It has been 

 recorded in literature from the following states: Massachusetts 

 (Faxon), Connecticut (Walden), New Jersey (Davis), Ontario 

 (Walker), Georgia (Allard), Illinois (Forbes), Kentucky (Garman), 

 Minnesota (Lugger), Kansas (Tucker), Nebraska (Bruner), Michigan 

 (Allis), Cuernavaca, Morelos, Mexico (Rehn), Cuba (Kirby). 

 From specimens examined we can record its distribution in the 

 following states: Colorado and Utah (Titus), Ohio (Kostir), New 

 Jersey, North Carolina, Connecticut (Amer. Mus.), California 

 (Doane); Maine, one specimen (Patch), Cuba (Cardin). From 

 correspondence we have obtained other records as follows: Texas 

 (Newell), North Carolina (Beutenmiiller), California and Washington 

 (Melander). 



description of life stages. 



Egg (Fig. 31, c). — The egg is about one-ninth of an inch long and from one-sixth to 

 one-fourth as wide. The color is dull white, often with a slight yellowish tinge. The 

 cap (Fig. 31, d) is a little narrower than the main body; its sides are parallel and the 

 end is broadly rounded. In color it is opaque white, but is often stained a reddish 

 color by the bark. The projections on the cap (Fig. 31, e) are long and finger-shaped,
