Sliming to pass upon this question now, I have accomplished my present 

 purpose by giving timely warning of the api:)earance in the Mississippi val- 

 ley of what may, unless it is closely watched, prove a serious enemy of the 

 favorite fruit of America. 



Until the life history of this species is complete, I can only say that the 

 strawberry fields should be inspected in fall and spring for evidence of the 

 presence of this caterpillar; and if it is found, it can be exterminated, as far 

 as we know, only by destroying the plants. It will, of course, be most likely 

 to occur in old and neglected fields, or, as at Normal, in runaway plants in 

 fence corners and by roadsides. I hardlj^ need say that these neglected 

 plants, living from year to year without " rotation," are the best possible 

 breeding places for strawberry pests, and may easily become centers of 

 infection for a whole neighborhood. 



Otiorhynchus sulcatus, Schoen. 



Order Coleoptera, Family Otiorhynchidfe. 



This is a rough, brownish black snout beetle, about four-tenths of an inch 

 long, of whose injuries to the strawberry I only know the fact reported by 

 Prof. Riley in his third report, that it infests the crowns of these plants; 

 doubtless in the larval stage. This species may be distinguished from the 

 other members of its genus by the fact that the femora are provided with a 

 very small tooth, while the rostrum is sulcate, with a bifid carina at the tip; 

 and the elytra are also longitudinally grooved. The thorax is sub-cylindrical, 

 with the sides moderately rounded, widest in front of the middle, snd the 

 surface rather closely set with rounded tubercles. Each interval of the ely- 

 tra bears a row of shining, rounded tubercles, rather closely placed, and 

 small patches of short yellowish hair, irregularly distributed. 



The Strawberry Crown-borer. Tyloderma fragarise, Riley. 

 Order Coleoptera, Family Curculionidse.

Although it has hitherto done but little harm north of the latitude of Cen- 

 tral Illinois, this species certainly occurs as far northward as Minnesota, and
