extending to the base of the antennae. The thoracic stripes are 

 brown and narrower than in the male, the metanotum just below 

 the scutellum white. The base of the first abdominal segment 

 shows two depressed, subdorsal areas, base of the second and the 

 fifth, sixth and seventh segments, and tip of the ovipositor, brown. 

 The halteres and legs as a whole are slightly lighter in color and 

 wings broader than in the male. Length the same, 8 mm. 



The male was described by Edward Burgess (Proc. Boston Soc. 

 Nat. Hist., 1878, vol. 19, p. 320), from a specimen collected about 

 1872 near the U. S. Arsenal, Springfield, Mass., by Dr. George 

 Dimmock. It was next captured by Mr. William Reiff near Ellis 

 Station, Norwood, Mass., April 18, 1909 and recorded by the 

 writer (Psyche, 1909, vol. 16, p. 132).^ It was again taken by Mr. 

 Reiff April 21, 1912, and by the writer at the same locality. May 3, 

 1918. I have also received a specimen for determination from Mr. 

 H. L. Johnson, collected at South Meriden, Conn., April 17, 1915. 



Among the species of the family Xylophagidse, Glutops singularis 

 is not the only rare species. The following are represented only by 

 single specimens in the collection of the Boston Society of Natural 

 History: Arthropeas americana Loew, Cheshire, Mass., June 30; 

 Rhachicerus nitidus Johns., Bar Harbor, Me., July 24; Solva 

 aterrima, Johns., Franconia, N. H. (Mrs. Slosson); S. tenthredinoides 

 V. d. Wulp, Bretton Woods, N. H., June 29; Xylophagus nitidus 

 Adams, Mt. Washington (Mrs. Slosson); Ptiolina edeta Walk., 

 "Alpine Garden," Mt. Washington, July 4. There is a single 

 record for New England of two other species, Rhachicerus fulvi- 

 collis Halid., Beverly, Mass. (Edw. Burgess) and Xylophagus 

 longicornis Loew, Mass., but neither are represented in the Society's 

 collection. 



Two Interesting Additions to the Odonate Fauna of 

 Concord, Mass.
