A number of Clivina? and other Carabidae usually found in moist 

 situations, were taken in the driest parts of sand plains. 



The most important discovery among; the Orthoptera, is the 

 capture of two specimens of Myrmecophila at Portland, Or. So 

 far as known, there is but a single authentic record of the occur- 

 rence of the genus in this country. 



A few species of Perlids were very abundant ; a large series of 

 two rare Gomphids were taken, and the occurrence of the genus 

 Calopteryx on the banks of the Yakima, is of importance, as it is 

 the first record of the genus west of the Rocky mountains, which 

 were supposed to be a barrier to their western progress. As spe- 

 cies occur far north, it is suggested that the passage is through 

 the mountain passes beyond the limits of the United States. 



A point of interest, and noticeable throughout W. T., is the 

 late hour at which insects are on the wing. It was a matter of 

 common occurrence to see Odonata belonging to the genera 

 Aeschna, Libellula, Diplax, &c, hawking about from after sun- 

 down till dark. In New England and Europe, with the excep- 

 tion of a few species of Aeschna and Cordulia, none are seen 

 • on the wing later than the early afternoon. 



The Army- worm in 1882. — The damage to crops from the 

 Army-worm in the more northern States, which we predicted in 

 the June number of the Naturalist, while not nearly so great as 

 in 1880, has still been marked in certain localities, notably in 

 Saratoga county, N. Y. The year 1S82 will, however, be noted 

 as a disastrous Army-worm year in many of the Southern States 

 Never before in the history of its appearances has the worm 

 been so general south of Mason and Dixon's line. The first 

 week in May it appeared in force in the northern counties of Ala- 

 bama, and shortly afterwards in nearly all the : ' 





nved from Ken- 



md Maryland, and in June some 

 fields of grain in the District of Columbia were badly damaged. 

 The first week in August a correspondent in Avoyelles parish, 

 La., sent us genuine northern Army-worms, with the report that 

 they were great lv iniuring the corn crop, but wvrc not so numer- 

 ous as they had 'been in May and June. Moreover. Dr. Chas. 

 Mohr informs us that the hay crop around Mobile, Ala , was 

 completely ruined by an army-worm which, from all accounts, 

 seems to be the true Lcitcama unipuncta. 



The Wheat-stalk w.okm on the Pacific coast -Mr. J A- 

 Starner, of Dayton. Columbia counts-. Washington Iemtory, has 

 recently sent us wheat-stalks containing larva: winch he states 

 have caused a shortness of the crop for several years. An exam- 

 ination of the stalks showed many larva? and pupae seemingly 

 identical with those of Isosoma iritici Riley, described in the 

 March number of the Naturalist, and working in a precisely
