 from southern rana<la to the (lulf, but is unknown aonj^- the Atlantie 

 Seaboard, ami wholly unrei)orted from the Pacific Slope south of NVash- 

 injjton, (unless, as above, in Me,\ico) and it hardly ranj^es as far north 

 as M. fenutrntus. 



IJruner in (uui of his accounts of this species says it is "a lover of 

 rank and succulent ve<;etatiou, sut*h as is found upon bottom hnnls, 

 alon^ the edf:es of cultivated fields, at the margins of woodlands and 

 on the shadeil mountain sloi»es.'' When "it develoj)S in larj:e num- 

 bers, then these haunts are forsaken, to a j-reater or less extent, and it 

 spreads over cultivated fields, eating the choicest of everythinj:." In 

 Iowa, Mr. J. A. Alh'u found it conruon on dry prairies, as well as in 

 moist sloujfhs on tall <;rass. 



It seldom develops any marked mijiratory i)ropensity and its e;L;.i;- 

 laving habits "•differ considerablv from those of the smaller miuratorv 

 spe<*ies, insomuch as })ut one or two clusters or pods are deposited by 

 a "igle female. Nevertheless, Just as many e^jjs are laid bv each 

 female insect. These ejjjis are deposited in i)rairie sod or any comjjact 

 vsoil in the vicinity of the regular haunts or feedin<»" places. ( )hl roads 

 and closely cropped i)astures. when located handily, are favorite resorts 

 for the heavily laden females when attending- to this mission of tiieirs.*' 

 (Bruner.) 



Its destructiveness appears to be mainly confined to oiass. jrrain, 

 ami garden vegetables. It appears in the winged state the last of 

 June or early in July, but eggs are not laid until late in August; 

 sixty-two to seventy-two eggs have been counted in the egg i)ods by 

 Donald Gunn in Manitoba. 



Blatchley has taken the male of this species in eoitu with .1/. femo- 

 )((tu.Sj aud considers them the same species, as do many others. The 

 range of the two species, which are certainly very closely allied, differs 

 to a considerable extent, though both are found over a large extent of 

 territory side by side: one is a seaboard a'ul northern form, the other 

 an interior species. Besides the dilierences in the hind tibiae, which 

 raiely cause hesitation i' attempting to separate them, there are slight 

 difiereiices which 1 have attempted to state, in the abdominal append
