Singular " Insect Injury." — We recently received a singular 

 specimen of insect injury in the shape of a "minnie " ball which had 

 been gnawed through by a wood boring larva. The ball had been 

 fired into a red oak tree, probably during war, and 

 when split out of the log, a few days ago, was found 

 in the track of a full grown larva — probably of an 

 Orthosoma — the burrow leading directly through the 

 bullet. This the grub had evidently struck at its 

 concave end, boring two -thirds its length and com- 

 ing out at one side somewhat below the apex. The 

 larva was found in the burrow, alive, only a short 

 distance above the bullet, the latter nearly retaining

flattened. The specimen was found by Dr. W. O. Eversfield, near 

 the Agricultural College, Maryland, and both bullet and larva pre- 

 served together. — Chas. R. Dodge. 



I have just received from Prof. E. D. Cope intelligence of the capture 

 of the second specimen of Dromicus flavilatus Cope, in the United 

 States, the particular locality being near Lake George, Florida ; the 

 first having been discovered by the writer near Fort Macon, N. C, in 

 187 1. Prof. Cope in his original paper describing the specimen states 

 as follows: " This species is of especial interest as the first represen- 

 tative of a West Indian and Mexican genus found in the Nearctic 

 Region. No species of Dromicus has been known in North America, 

 and the occurrence of this one on the extreme coast, and its very close 

 affininity to a species (D. callilcemus Gosse) common in Jamaica, are 

 circumstances suggestive of origin by carriage in floating drift-wood 

 in the gulf stream." — H. C. Yarrow. 



GLEANINGS IN FOREIGN FIELDS. 



Commensalism among Catapillars. — In a recent number of 

 Nature there is a communication on an interesting case of commens- 

 alism, from Fritz Muller, Itajahy, Brazil, accompanied by an illustra- 

 tion of a large spiney caterpiller upon a leaf, having a smaller cater- 

 pillar upon it. He says ; " The larger caterpillar, protected by long
