found under the bark of chestnut, maple, and hickory, fed freely in 

 confinement on pieces of the bark, one example living from May 24 to 

 July 2. 



The writer has not been able to ascertain the larval habits of these 

 last two species, but it may be surmised that they live under or in the 

 bark somewhat after the manner of C. parochus in butternut. 



Plocamus hispidulus Lee. — Beaten from limbs, and probably lives on 

 this tree, as it has been found by Mr. Schwarz breeding in the "outer 

 layers of nearly dead wood " of locust. 



Dryocoetes granicollis Lee. — Two colonies observed at base of trees 

 near roots; insect in all stages, mostly pupre and immature imagos. 



Other species of Cerambycidse, found at Wedderburn and elsewhere 

 on chestnut, have been reported upon by the writer in the Proceedings 

 of the Entomological Society of "Washington (Vol. Ill, pp. 95-102), 

 and need not be again mentioned at any length. The list includes: 

 Callidium cereum Newm.; Xylotreclius colonus Fab., and its parasite, 

 Xylonomus rileyi; Neoclytus erythrocephalus Fab., and its parasite, 

 Br aeon euryg aster; Cyrtoplwrus verrucosus 01. ; Euderces picipes Fab.; 

 Lepttostylus macula and collaris; Liopus variegatus, and its parasite, 

 EpMaltes irritator, and predaceous enemy, Tenebroides corticalis; and 

 Eupogonius vestitus Say. 



DAMAGE TO PINES. 



A year or two before the reports of insect damage to chestnut trees, 

 came complaints of injuries to coniferous trees in Virginia, West Vir- 

 ginia, and District of Columbia. The first of these was from Mr. M. H. 

 Farley, of Strom, Botetourt County, Va., who wrote October 26, 1891, 

 of the "frightful devastation" in the pine timber of that State. The 

 scrub pine (Pinus inops) was attacked first, and it was thought that 

 unless the insect was checked it would "soon sweep the pine timber 

 from the State." The insect, which proved to be Bendroctonus frontalis, 

 was apparently working southward, having at that time reached the 

 North Carolina line. It was also reported present in white pine (P. 

 strobus). 



During September, 1892, Messrs. J. E. Beaty & Co., of Crow, W. 

 Va., reported that the same insect was apparently the cause of the 

 destruction of pines in Baleigh County of that State, as well as in Vir- 

 ginia. 



Other reports of damage reached the Department during the next 

 few months, one of which, emanating from Port Bepublic, Va., was the 

 occasion of a visit by Mr. E. A. Schwarz of this Division, but did not 

 result in the finding of a single living specimen of Dendroctonus at that 

 place, although thousands of dead beetles were in evidence of their pre- 

 vious abundance and injuriousness. This was in August, 1893. 



One result of this trip was the discovery of a fungoid disease which 

 manifested its presence upon the dead bodies of the beetles under the
