United States, it is well represented. Many of the specimens have 

 been reared. 



The genus Merinus LeConte is represented by its only species, 

 laevis (Olivier). The material, associated with reared adults, con- 

 sists of several larvae and pupae collected by the writer near Falls 

 Church, Virginia, July 23, 1918. The rest of the larval material, 

 not associated by rearing experiments, consists of the following 

 specimens : one larva taken by H. S. Barber from a dead branch in 

 the top of a cherry tree at Occoquan, Virginia, July 4, 1908; a second 

 larval specimen taken from beneath the bark of a dead maple tree 

 at Dead Run, Virginia (opposite Plummer Island, Maryland), Feb- 

 ruary 17, 1915 (H. G. Champion, collector) ; and a third specimen 

 taken by the writer from under chestnut bark at Black Pond, Fair- 

 fax County, Virginia. 



The genus Xylofinus LeConte is represented by both its species, 

 sayerdioides (Olivier) and aenescens LeConte. The material con- 

 sists of several specimens of saperdioides associated by rearing, 

 as follows: larval skin (larva taken by A. B. Champlain from a de- 

 cayed sycamore tree at Harrisburg, Pennsylvania, April 7, 1913, 

 and adult reared June 10, 1913) ; several larvae taken by F. C. 

 Craighead from the heartwood of a dead, dry oak log at Great Falls, 

 Virginia, May 30, 1916 (pupa collected with these transformed June 

 8, 1916) ; and several larvae taken by F. C. Craighead from beneath 

 the bark of a decayed oak log near Great Falls, Virginia, May 25, 

 1919 (adults reared June 4, 1919, from part of the same collection). 

 The material representing the species aenescens, consists of two 

 larval skins; one of larva taken by T. E. Snyder from beneath the 

 bark of a decayed oak at Shipman, Virginia, October 11, 1913, and 

 from which adult was reared May 28, 1914; another of larva taken 

 by T. E. Snyder at Black Mountain, North Carolina, March 22, 1913, 

 which pupated April 15 and transformed to imago May 9, 1913. 



The genus Haplandrus LeConte, of which there are three species, 

 is represented by fidvipes (Herbst). The material associated by 

 rearing consists of the following specimens: Four alcoholic larvae 

 and one larval skin, the latter from a specimen which pupated May 

 15 and issued May 23, 1913, all out of a collection of five larvae taken 

 by A. B. Champlain from a dead white pine at Charter Oak, Penn- 

 sylvania, April 10, 1913 ; and ten alcoholic larvae and one larval skin, 

 the latter from a specimen which was reared through to adult April 

 16, 1914, all out of a collection of eleven larvae taken by E. A. 

 Schwarz and H. S. Barber in a dry trunk of redbud at Plummer 

 Island, Maryland, August 27, 1913. Of the material not associated 

 by rearing there are several specimens taken from a rotten oak at 

 Plummer Island, Marjdand, by Messrs, Schwarz and Barber. Other 

 specimens were collected as follows : Larval skin and adult taken by
