reach the insects. When used in this way about one tablespoonful of 

 the Paris green is dissolved in a bucketful of water, and is sprinkled 

 over the vines by means of an ordinary sprinkler, old broom, or some 

 of the patented sprinklers or spray machines now so common. 



Caution should always be used in handling the Paris green, as it is 

 quite poisonous, and it should never be left where children can have 

 access to it, nor should they ever be allowed to use it, its poisonous 

 quality being the chief objection to its use. 



A fuller account of this species, its natural enemies, and the various 

 remedies used, will be found in the "General Remarks," at the end of 

 this report. 



Chrysochus auratus — Fabr. (The Golden Chrysochus.) 



This species is not introduced here because it is injurious to useful 

 vegetation, for it feeds almost exclusively on the leaves of the dog's- 

 bane (Apocynum androsasmifolium), but on account of its great beauty 

 and common occurrence throughout our State. 



It varies in length from about three-eighths to nearly or quite half 

 an inch, the width 'across the elytra about equal to half the length ; 

 the body thick and very convex above. Thorax narrower than the 

 elytra, squarely truncated behind, rounded and nearly semi-circular 

 in front ; very convex. Antennas nearly half the length of the body, 

 slightly enlarged toward the tip. Elytra not striate, but slightly 

 punctured, and smooth. Color a beautiful shining, golden green, 

 without spot or stripe, often varied on the elytra to bright coppery 

 reflection ; the under side dark green, with bluish reflections, often 

 deepened almost to black or blue-black ; mouth parts and antenna? 

 black ; legs dark green or blue-black ; pads of the tarsi tawny or buff. 



Colaspis flavida — Say. (The Grape-vine Colaspis.) 



This is a quite small insect, scarcely one-fifth of an inch long, of the 

 usual oval form, the width about half the length ; thorax nearly as 

 wide behind as the elytra, a slight transverse depression in front ; 

 elytra or wing-cases distinctly grooved, there being six or seven 

 grooves on each case (six compl-ete, or seven, including the incom- 

 plete), each with a double row of punctures in it. Of a clay-yellow 

 color, uoiially without stripe or markings ; the under side is a little 

 deeper color than the upper side ; the tips of the antenna? are usually 

 black, and sometimes the margins of the elytra are dark. 



This is more common in the Eastern States than in the West, but 

 we evidently have one or two varieties quite common in the West ; 

 what injury they do I am unable to say ; but as this species is found 

 on the wild grapes, and has been known occasionally to attack the 

 cultivated vines, riddling the leaves with holes, it is more than prob- 

 able that our grapes suffer more or less from them. 



According to Rile}'', the larva? devour and work into the roots of the 

 strawberry plant, and, having passed the winter there, appear in 

 June or July in the beetle state, feeding in this state first upon the 

 strawberry leaves, and afterward spreading to the grape vines. The 

 following is his description of the larva. 



Larva — Color yellowish; body slightly arched; anal joints smaller 

 than the others. First joint horny above and of the same color as
