it was very destructive on tobacco; as also in Person, o^J". C; in Cherokee, 

 Ala.; in Robertson and Montgomery, Tenn." In the Report for Novem- 

 ber and December, it is stated that "Owsley, Ky., reports a great 

 destruction of early-sovpn wheat by a grasshopper, which is most proba- 

 bly the Caloptenus femur-ruhrum.^' 



Besides the localities given by ProfessorThomas, I have received a male 

 from California, near San Francisco, through Mr. Henry Edwards. The 

 specimen was submitted to Mr. Scudder, who identified it. Mr. Walker* 

 gives the following localities for it: "Arctic America; presented by Sir 

 John llichardson. Arctic America; presented by I)r. Kae. Vancou- 

 ver's Island-Nova Scotia ; from Lieutenant Redman's collection. West 

 coast of America; presented by Captain Kellett and Lieutenant Wood," 

 etc. 



On the map showing the distribution of this species, I have represented 

 it as occurring over the whole of Labrador, for if it is found in Arctic 

 America, it must be found there. During a residence of six weeks in 

 the summer of 1800 at the mouth of Esquimaux River, Straits of Belle 

 Isle, I never met with any Ortlioptera. 1 heard, however, of grasshop- 

 pers about 20 miles in the interior, but they were very few in number. 

 In the summer of ISGi, while entomologizing at dilferent points as far 

 north as Hopedale, I never saw any. 



We still need information regarding the southern and southeastern 

 limits. I have also indicated on the map the approximative limits of 

 the area where it has been found to be destructive at certain seasons. 



Description. — Grizzled with dirty olive and brown ; a black spot extending from tlie 

 eyes along the sides of the thorax ; an oblique yellow line on each side of the body 

 beneath the wings ; a row of dnsky brown spots along the middle of the wing-covers, 

 and the hindmost shanks and feet blood-red, with black spines. The wings are trans- 

 parent, with a very pale greenish-yellow tint next to the body, and are netted with brown 

 lines. The hindmost thighs have two large spots on the upper side, and the extremity 

 black ; but are red below and yellow on the inside. The appendages at the tip of the 

 body in the male are of a long triangular form. Length, from 0.75 to 1 inch ; expan- 

 sion of wings, 1.25 to 1.75 inches. — (Harris.) 



As this species, which is so common, varies considerably, I have concluded to give 

 Dr. Harris's description without change, adding the following : Vertex but slightly 

 depressed, with a minute angular expansion in front of the eyes; frontal costa 

 usually but slightly sulcate ; sides parallel ; eyes large and rather prominent. Elytra 

 and wings generally a little longer than the abdomen. The cerci of the male rather 

 broad and Hat; apex of last ventral segment is entire and truncate. The yellow 

 stripes on the side extend from the base of the wing to the insertion of the posterior 

 femora. The ground color varies with localities and age, and most of the specimens 

 from one or two sections appear to have unspotted elytra; sometimes a reddish-brown 

 tint prevails ; at others a dark olive ; at others a dark purplish-brown ; yet the mark- 

 ings generally remain the same. — (Thomas, Acrididte N. A.)

"A third species of grasshopper, unnamed as yet, belonging to the 

 genus CEdipoda, appears to be the insect which has ravaged the culti- 

 vated districts of California and Oregon, and the neighboring States 

 and Territories. It probably ranges over the whole extent of country 

 west of the Rocky Mountains and included within the limits of the 

 United States. Mr. A. S. Taylor, in one of his articles in the Cali- 

 fornia Farmer, subsequently communicated to the Smithsonian Institu- 

 tion and published in their Report for 1858, describes the grasshopper 

 as found near Monterey, and it is doubtless the migratory species which 

 ravaged the State. It is a species of CEdipoda, which, from the devas-
