<lian carina. In the description of the anterior and median legs, 

 the word "tibiae" was used where "tarsi" was intended. 



In the paper above alluded to a variety from Pine Ridge, Neb., 

 Was described. This specimen was taken in July. Aside from 

 the differences already given no more need be said, except that 

 if this is solidaginis var. it extends the range over the entire 

 state of Nebraska. Pine Ridge is a high, broken range of foot- 

 hills, of the Arikaree formation, varying from 4,300 to 5,000 

 feet, bordering on the barren Little Bad Lands in Sioux county 

 at the extreme northwest corner of the state. 



Lincoln is in a comparatively flat country, on the other hand, 

 with an altitude from 1,100 to 1,200 feet. To the north and 

 west of the city lie extensive salt basins in the valley of Salt 

 creek. Concerning these salt basins, Prof. Barbour says: 1 "The 

 area of salt land soil is too restricted to be mentioned, being 

 confined to Salt creek and other salt marshes near Lincoln." 



Myoditcs solidaginis is also found at West Point, Neb. This 

 latter place has no salt land or alkaline earth, but does present 

 sandy flats in the vicinities near which Myoditcs is taken. 



At Lincoln Myoditcs is only taken in the vicinity of the salt 

 Basins.. In the latter part of August, from the 23d to the 27th, 

 it is difficult to find a Solidago plant without at least one beetle 

 feeding on its flowers. 



Solidago missonriensis, S. canadensis, and S. rigida are the 

 common species, and each in its season is visited. 



It is worthy to note the abundance of this particular species 

 in this locality as compared with the supposed scarcity of other 

 species of the genus Myoditcs in other parts. Reasons will be 

 suggested for this abundance in another place in this article. 



A close examination of the buds of goldenrod at which Myo- 

 ditcs has been seen always results in finding one or more young 

 of this beetle. I shall use the term "triunguloid" because of the 

 similarity to the triungulins. "Triungulin" would be a misnomer 

 for this larva and also for the Sty lops larva. 



The triunguloid is a light brown hexapod averaging about .82 

 mm. in length and .21 mm. in breadth, broadest toward the apex
