 (After Riley.) 



brown scales; elytra with a 

 whitish or pale stripe ex- 

 tending from the humerus to 

 middle along the margin, 

 thence obliquely upward to- 

 wards the suture. Head and 

 beak longer than thorax, den- 

 sely punctured. Thorax sub- 

 cylindrical; disc with a fine 

 median line, densely punc- 

 tured. Elytra regularly oval, 

 base subtruncate without hu- 

 meri; disc indistinctly striate, 

 with rows of large, rather 

 closely placed punctures; inter- 

 vals as in tessellatus. Length 

 6.58.5 mm. (Fig. 49.) 



Not in the collection at hand from Indiana, but undoubtedly 

 occurs about greenhouses in the State, as it ranges from New 

 England and Wisconsin to California and Hawaii, and as far 

 south as Florida. Now rarely found even in greenhouses near 

 New York City. Little Falls, N. Y., Oct. IS, on carnations. Ac- 

 cording to Chittenden (1901, 88 96) it is known in economic 

 literature as "Fuller's rose beetle," as it attacks cultivated roses 

 and geraniums and many other greenhouse plants, as well as 

 citrus and other fruit trees. It is destructive in both larval and 

 imago stages, but does most damage as a larva when it lives in 

 the soil and feeds upon the roots of its food plants, while the 

 imago attacks the foliage, flowers and buds. The beetles are noc- 

 turnal in habit, feeding only after dark, and the female secretes 

 her eggs by thrusting them with her beak between the loose bark 

 and base of the stem near the ground. They are laid in batches, 

 each lot containing from ten to 60 eggs. The latter require about 

 a month to hatch. The best remedy so far known is to search for 

 and destroy the beetles when they are on the plants at night, or 

 to place traps, such as chips and boards, near the roots, under 

 which they will hide at night. The larvre can be readily destroyed 

 by injecting with a small metal syringe a few drops of carbon 

 bisulphide or a larger amount of kerosene emulsion about the 

 roots. Fertilizing with tobacco waste and spraying with arsenate 

 of lead is also recommended. From trees or shrubs the beetles 

 may be excluded by wrapping with cotton bands.
