THE CANADIAN ENTOMOLOGIST. 131 



A NEW SPECIES OF PTEROMALID^E. 



BY A. B. GAHAN, ASST. ENTOMOLOGIST, MARYLAND EXPT. STATION. 



Forster in 1S56 characterized the new genus Coelopisthia, (Hymen. 

 Studien. II, 1856, p. 65) using as the type Walker's species, Pteromalus 

 cephalotes, described by that author in 1836 from the Isle of Wight 

 (Entom. Mag. Ill, 1836, p. 481). In 1878, Thomson described another 

 European species, C. vitripennis (Hymen. Scandin. V. 1878, p. 16). 

 These constitute all the species of the genus recorded up to the present 

 time. It is my privilege to now describe a third species, the first occurring 

 in North America. It is readily distinguished from those previously 

 described by the large fuliginous spot on the fore wing. 



Coelopisthia famosipennis, n. sp. — Female : Length 2.3 mm. Aeneous. 

 Head broader than the thorax, densely and coarsely punctured ; eyes 

 black ; scape two-thirds as long as flagellum, yellow ; pedicel longer than 

 first two joints of flagellum, yellow ; flagellum black. Prothorax, meso- 

 thorax except axillae and scutellum which are shagreened, and metathorax, 

 coarsely and densely punctured, the latter with a distinct median carina. 

 Anterior wings except basal one-third and a broad margin at the apex 

 fuliginous ; posterior wings hyaline, iridescent. Legs pale yellow, slightly 

 fuscous at apex of femora ; the coxae are metallic green. Abdomen 

 smooth, shining black with cupreous reflections. 



Described from three female specimens reared from Lepidoptera 

 pupa, College Park, Maryland, July 27th, 190S. Two of the type speci- 

 mens are deposited in the United States National Museum, the third in 

 the collection of the Maryland Experiment Station. 



Identified as a new species by Mr. J. C. Crawford, of the United 

 States National Museum, to whom the writer extends his thanks for this 

 as well as many other courtesies. 



THE EDWARDS COLLECTION OF BUTTERFLIES. 

 "A very interesting personal note occurs in the current number of 

 the Canadian Entomologist, to the effect that the late Mr. W. H. 

 Edwards, finding himself without the necessary funds to publish the 

 third volume of his 'Butterflies of North America,'' contemplated offering 

 his collection of North American butterflies to the Trustees of the British 

 Museum, in order to secure the money to enable him to go on with his 

 work. To prevent the types of his species going out of America, Dr. W. 

 J. Holland offered to pay the bills for the publication of the third
