The beetle is short-lived. The female deposits her eggs in the ground 

 during the latter part of June, and having thus provided for the continu- 

 ance of her species, dies. The eggs are laid during the night, singly and 

 at different depths, the number probably not exceeding twenty in all. They 

 are very large for the size of the beetle, being nearly one-tenth of an inch 

 in length, of a long ovoid form and white translucent appearance. 



In less than a month the young larva is hatched : it is of a dull white 

 color, with a brown polished horny head and the extremity of the abdomen 

 lead color. The mature larva (fig. 10) is a thick, whitish, 

 fleshy grub, very similar in appearance to that of the com- 

 mon May Bug, familiarly known as " the White Grub." It 

 lives in the ground and feeds on the roots of plants, and 

 on this account it is sometimes very destructive to straw- 

 berry patches. 



Fi s- IO - Several years are required to bring this grub to maturity ; 



finally it reaches its full growth in the fall, and changes to the perfect 

 beetle early the following spring. 



THE SCIENTIFIC NAMES OF INSECTS. 



BY GEORGE D. HULST, BROOKLYN, N. Y. 



It is our desire in the present article to call attention to two pretty 

 well established laws of nomenclature, that with a few seconding words on 

 our part, the laws may, " to those whom it may concern, " preach the 

 importance and necessity of their being observed and obeyed. 



i st. " All scientific names must be Latin or must be Latinized." The 

 laws which govern the structure of the Latin language must apply in every 

 case in the making of the binomial combination. 



In the making of the binomial, four methods of construction are in 

 use. The generic name is always a noun. The specific name is (a) ' a 

 proper name in apposition with this, as Papilio ajax, the Papilio called 

 ajax ; (b) an adjective giving some description or characteristic, as Colicis 

 occidentalis — the western Colias, Cossus Caitcraisis — the Cossus living at
