SCARRED SNOUT-BEETLES.

The insect is very convex; the thorax has a projecting angle at 

 each side, and the body is almost egg-shaped. 



Judging from the work seen sucli snout-beetles can become 

 very destructive, and it will be difficult to combat them. Many 

 vears ago a snout-beetle infesting the roots of grasses was very 

 numerous in Druid Hill Park, Baltimore, Md., yet its presence 

 was not suspected at all, as no injury to the lawns was noticed, 

 except that the plants seemed to need food, which was provided 

 them in the form of a very bad-smelling manure obtained from 

 cleaning hog-bristles imported from Hungary for the manufac- 

 ture of brushes, etc. A liberal application of this substance was

spread over the lawns, and was followed by a heavy rain. Next 

 day immen.'^c numbers of beetles (Sphciiophoriis parinlns G}'11.) 

 could be seen upon all the sidewalks and seats on and about the 

 lawn ; they were evidently driven out of the ground by this of- 

 fensive manure. Perhaps this experience might show us a meth- 

 od by which we could combat this and similar insects. 



Two other species of the genus Otiorhyitcliiis (O. sulcatiis 

 Fab., and 0. picipcs Fab.), as well as Thricolepis siinulafor Horn, 

 are known to injmx the apple elsewhere.
