﻿OF THE STATE ENTOMOLOGIST. 149 



■never been reported Irom Missouri till the present year. It is pret- 

 tily marked as in Fig. 45, and occurs in two distinct varieties, one in 

 which a bright yellowish-green prevails, and the other in which pale- 

 brown predominates. There can be no connection between its ap- 

 pearance and that of spretus, other than that the exodus of this last 

 rendered more conspicuous, all large insects of this kind that were left 

 behind. Keportswere circulated and published last February that 

 '' the grasshoppers had appeared again at Independence, and in other 

 parts of the State." The following letter from Dr. B. F. Dunkley, of 

 Dunksburg, Pettis county, will show how easily people are misled: 



Inclosed please find some youn^ locusts, just hatched out. We believe them to be 

 the Rocky Mountahi locusts, but send them to you to decide. Please answer. In my 

 report, in answer to your circular, I said that some of the locusts that hatched out late 

 and only grew to half the size of others that migrated and left us last July, did lay their 

 eggs, for myself and others saw them at it. Now I think these are Irom the eggs laid 

 by^them. If so, will the cold, when it comes, kill them? 



All opinions like those expressed by Mr. Dunkley are based on 

 ^'mistaken identity." The species noticed hopping about, during the 

 mild weather of January and February, are native species that are 

 [Fig. 4(5.] with us all the time, and 



/^K. ^^^^ .r-my^ habitually hibernate in the

green-stripedLoccst:— a, larva; b, perfect insect. Duukloy and other Corres- 

 pondents, is the Green-striped Locust {Tragocephala viridifasciata^) 

 a. very common species, ranging from Maine to Florida, and from the 

 Atlantic to Nebraska. It passes the winter in the immature con- 

 dition, sheltering in meadows and in tufts of grass, and becoming 

 active whenever the weather is mild. It is sometimes found in Win- 

 ter in the early larva stages but more often in the pupa state, and 

 becomes fledged toward the end of April. 



It difl"ers generically from the Rocky Mountain Locust, which 

 hibernates in the egg state. This Green-striped Locust, as its name 

 implies, has, when mature, a broad green stripe on the front wings, 

 and in the narrower, humped and keeled thorax or fore-body, (Fig. 46) 

 may at once be distinguished from the dreaded Rocky Mountain pest. 

 Like so many other species of its family it occurs in two well marked 

 varieties, one in which, in addition to the stripe on the front-wings, the 

 whole body and hind thighs, above, are pea-green; the other in which 

 this color gives way to pale-brown. In both varieties the hind wings 

 are smoky with the basal third greenish. 



The species noticed by Mr. Dunkley to hatch out late and to lay 

 •eggs in the Fall was more probably femur-ruhrum than spretus.
