Rhaphidophorinae 



Ceuthophikis sp. — Bottineau, Aug. 9-20, 1920 (A. H. East- 

 gate and N. A. Wood), 2 males, 3 females. 



These specimens were collected in an outside covered stair- 

 case leading to the cellar of a house in Bottineau. Five other 

 adults captured on the loth of August were placed by Mr. 

 Eastgate in a tin can, from which they escaped during the 

 night by chewing their way through the cloth cover. 



It has been impossible to get this species determined. Speci- 

 mens sent to Mr. Rehn were returned with the statement 

 that the western forms of this genus were in too much con- 

 fusion to make it possible to say what this species was. The 

 coloration, male genitalia, armature of the posterior femora, 

 and female ovipositor are all distinctive, but the descriptions 

 in Scudder's monograph"^ are so unsatisfactory that it has 

 been impossible to place the species by their means. 



CcH]thophilus sp. — Grand Forks, Grand Forks Co. (H. A 

 Shaw), I female. 



A single specimen taken many years ago by Mr. Shaw was 

 received from Mr. Eastgate. The remarks made concerning 

 the last species apply also to this. It seems to be fairly close 

 to C. gracilipes Haldeman (as used by Blatchley), but differs 

 notably in the lighter coloration, less distinct dorsal stripe, 

 larger size, and considerably smaller ovipositor. 



Cciithophilus niaculatiis (Harris). — Devils Lake, Jwly 9, 

 1919, 2 males; (?) May 7-1 1, 1921 (N. A. Wood), 3 juve- 

 niles; Grand Forks, Grand Forks Co., July 20-21, 1921 (C. 

 Thompson), 2 males, 5 females; Pembina, Pembina Co., July 

 15, 1 92 1 (C. Thompson), i male, 2 females. 



This species was taken in the woods bordering the lakes
