Forty- SIXTH Report on the jState Museum 



S. frontalis, although common, has not as yet attained as bad a rep- 

 utation as has some of its ^ongeners, as for example aS". blanda Mels.,* 

 which has gone on record as injurious to cotton, to potatoes, and par- 

 ticulary so to corn (see First Report on the Insects of JVew York, pp. 

 155, 156), and to beets (InseCt Life, iii, p. 149). S. tceniata (Say) 

 has been injurious to beans in Now Mexico {Insect Life, iii, p. 122) 

 and feeds on many of the Cucurhitacere, and has been taken in associa- 

 tion with a number of grass insects {id., iv, 198). ^S', elongata (Fabr.) 

 is at times destructive to cantaloupes in Maryland. 



Chauliognathus Pennsylvanicus (De Geer). 

 The Pennsylvania ^Soldier- Beetle. 

 Mr. C. R. Moore, of Bird's Nest, Va., has sent this beetle — one of 

 the Lampyridm — as a])pearing with the rose-bug in the latter ]:)art of 

 May, and eating roses and blossoms of grapes. 

 He was informed that the insect was not recog- 

 nized as an injurious one, although it was 

 known to feed on the pollen of various blos- 

 soms. Writing again, he stated that he had 

 observed the operations of the beetle on his 

 Fig. 81.- The Pennsylvania grapes for the past three years, and wherever

Should this form of injury by the beetle be established, it might be 

 •of more economic importance than tlie service rendered by it in its 

 •earlier stage of larva, when it is occasionally, at least, beneficial, in fer- 

 reting out and destiwing the ajDple-worm of the codling-moth and the 

 larva of the plum curculio and, as later discovered {Insect Life, i, p. 

 216), feeding upon the pupa? of the destructive cotton-woi'm. 



Pissodes strobi Peck. 

 I he White-pine Weevil. 

 An attack on the Norway spruce, of what was in all probability this 

 insect, was reported, in August, 1892, by W. C. Pierce, of Richford, N.Y. 



According to his statement, one hun- 

 dred and fifty Norway spruces, which 

 had been planted in the cemetery at 

 that place, commenced, last year, to die 

 at the top. On examination, small 

 borers were found working between 

 the bark and the wood from above
