430 FAMILY VI. ACRIDID.E. THE LOCUSTS. 



by reason of the record of Shull (1911, 227), who took it at Sagi- 



naw Bay, Huron Co., Mich., 

 June 22-August 3. Speci- 

 inens (identified for him by 

 Morse as M. fffdus Scudd.) 

 were taken "on bare or some- 

 what grassy beaches or in

or soil, not on vegetation." Three of the males from the Univer- 

 sity of Michigan collection are at hand and agree exactly in 

 everything but size with red-legged individuals of M. packardii 

 from Colorado. They measure from 22 24 mm. in length of body, 

 the western males from 24 to 30 mm. The range of M. packardii, 

 including its synonym, M. feed us Scudder (1879, 69) extends from 

 the Michigan station mentioned, north and west to Nicola Valley, 

 B. C., and the Pacific Coast of the U. S. and south and west to 

 Iowa, Texas and New Mexico. Specimens at hand collected by 

 Bruner, Gillette and others, are from Valentine, Nebraska, and 

 Greeley, Ft. Collins and Golden Gate, Colorado, some being 

 labelled M. jtarkardii, others M. fffdns. The latter, neither in 

 color nor structure, have any fixed characters separating them 

 from j>a<-L-ardii. Scudder, in his original description of fcedus 

 says: "This insect is closely related to M. iiackardii, but by its 

 dingy coloring presents a very different appearance." In his 

 notes on the same form (1897, 312) he says that the original types 

 from Pueblo, Colo., are all that he has seen and that it "differs 

 but slightly from M.. packardii and may prove to be merely a 

 varietal form of it, dependent upon station, which in this species 

 (fffdus) is in the dank vegetation of river bottoms where M. jturk- 

 ardii occurs but rarely." 



Morse (1907, 50) records packardii from various stations in 

 Oklahoma and Texas and states that he found it "common among 

 weeds and tall grass, varying greatly in amount of fuscous mark- 

 ings on pronotum and hind femora, as well as in color of hind 

 tibiae, apparently running into prdiis." R. & H. (1906, 413) men- 

 tion the great variation in color of Utah, Colorado and Montana 

 specimens, and state that "most of them were taken from luxuri- 

 ant weeds growing along ditches and drains, or about damp de- 

 pressions in the prairies. The insects were active, but often 

 clung tenaciously to the weeds in which they hid, and it was con- 

 sequently easy to capture as many as desired." In Colorado, says
