an inch.' Its fore wings are red, darker on the outer half, and with a large 

 triangular white spot near the middle of the front edge; the outer edge of 

 the spot is hollowed out. The outer edge of the wing is pale, especially in 

 the middle, and about the same color as the head and thorax ; the hind 

 wings and abdomen are of a whitish buff, underneath they are whitish. 



Various other species have also been brielly referred to as enemies of this 

 plant, but it does not seem worth while to multiply descriptions of them, as 

 the same principles must guide us in the destruction of all of them. Fire or 

 insect poisons, either arsenical or vegetable, like hellebore water, must be 

 used, according to the season when the worms or pupie occur upon the 

 leaves.

Prof. Riley states in his third report as State Entomologist of Missouri, 

 that this beetle greedily devours the leaves of the strawberry, commencing 

 to appear in June and continuing until autumn, although leaving the straw- 

 berry vines for other food, to a great extent, late in July and in August. The 

 following is Say's description of the beetle : 



" Pale yellowish ; elytra striate, with a double series of punctures. Body 

 densely punctured; punctures rather large and profound, head with two 

 slightly elevated tubercles between the antennae; thorax tinged with rufous; 

 elytra with elevated lines, of which the inner one curves round at base and 

 descends a short distance to unite with the sutural line; interstitial spaces, 

 excepting the subsutui'al one and the two exterior ones, with double series 

 of rather large profound punctures ; exterior edge blackish brown ; venter 

 dusky. Length nearly one-fifth of an inch. Var. a. Interstitial spaces of 

 the elytra black; beneath, excepting the feet, black." 



Prof. Riley's inference in the article cited, that this beetle is the adult of 

 the common root-worm of the strawberry, can not yet be regarded as estab- 

 lished as will be explained more fully under Paria aterrima, when treating of 

 species injurious to the root. 



The beetle (Colaspis) could, of course, be easily poisoned in the strawberry 

 field ; but as it feeds on the leaves of the grape as well, and possibly on some 

 other plants, such treatment might not be a complete remedy. 



Until the larva of this beetle is more certainly known, and its life history 

 has been thoroughly cleared up, we can not recommend more effective 

 measures.
