PRACTICAL ENTOMOLOGY.

Imago. — The only description in 

 American entomological works is 

 the following by Dr. Gr. H. Horn, 

 taken from the proceedings of the 

 American Philosophical Society, 

 vol. XV., p. Gl: " OtiorhyncJms 

 liqneus Oliv. Ent. v. 83, p. 378, 

 pi. 31, fig. 473. Form oblong, 

 color piceous, shining. Rostrum 

 flat, emarginate at tip, surface 

 very coarsely and closely punctured, 

 between the eyes a deep puncture. 

 Thorax nearly spherical, truncate 

 at apex and base, surface tuberculate (at middle the tubercles become con- 

 fluent in rows with deep sulci between them), each tubercle punctured at 

 summit and bearing a short hair. Elytra oval, striate at the sides, strife 

 obsolete on the disc and with coarse punctures closely placed, intervals flat 

 on the disc and feebly muricate, at sides moderately convex and slightly 

 tuberculate. Legs piceo-rufous, femora clavate, sinuate near the tip and 

 with a moderately strong tooth bearing a denticle on its free edge. Length 

 .20; 5 mm. 



"This is the smallest species which has occurred with us, and may be easily 

 known by the femoral armature, and the nearly spherical thorax with its 

 peculiar sculpture." 



GEOGKAPHICAL DISTRIBUTION. 



Dr. Horn states that the species occurs in the New England States, 

 but it doubtless has a much more general distribution. On this subject 

 Mr. E. A. Schwarz kindly writes: "The species ranges from the 

 New England and northern portions of the Middle States westward 

 to Minnesota and Iowa. Its southern limit I am unable to trace, but it cer- 

 tainly does not go very far south. From my own experience I know that the 

 beetle is very common at Cambridge, Mass., and Detroit, Mich., and that I 

 never met with it here at Washington. In Europe the species ranges from 

 Spain to France and England, but it occurs also, though rarely, in Italy and 

 Southern Germany." Mr. H. Garman informs mo that he has never collected 

 the species about Normal, 111., from which fact we may infer that it does not 

 extend very far south. 



FOOD PLANTS. 



Prof. Cook has found the beetles feeding on the leaves of borage; doubtless 

 they will be found to feed upon many other kinds of plants as well. It seems 

 probable that the larvae feed on other plants than the strawberry as I have 

 found the beetles in abundance in fields at some distance from either wild or 

 cultivated strawberries. As the beetles cannot fly it is probable that they 

 lived on other plants. This probability is strengthened by the fact that 

 closely related species live on a variety of food plants. 



PAST HISTORY. 



Absolutely nothing seems to have been known of the earlier stages of the 

 insect heretofore. According to Mr. Schwarz, the first mention of the
