ART. 25 NEW ICHNEUMON-FLIES CUSHMAN 15 



Family BRACONIDAE 



BRACHISTES MAGDALI (Cresson) 



Calyptus magdali Ckesson, Psyche, vol. 2, 1878, p. 189. 



Brachistes magdali Brues, Bull. Wise. Nat. Hist. Soc, vol. 8, 1910, p. 50. 

 (New syuoiiymy.) 



Both Cresson's and Brues's types are from Massachusetts and 

 both were reared from the same host, Magdalis olyra Herbst. 



BRACHISTES STRIGITERGUM, new species 



Of the same form as B. iimgdali (Cresson) but at once distin- 

 guishable by the strongly striate second tergite. 



Female. — Length, 5.5 mm. ; antennae, 5 mm. 



Temples broad but distinctly narrower than eyes, which are dis- 

 tinctly bulging, especially behind; vertex and temples moderately 

 densely and very finely punctate; face more coarsely and more 

 densely so; clypeus coarsely confluently punctate; eyes shorter than 

 in tiiagdali, being only about a third longer than broad and little 

 more than twice as long as malar space; basal two joints of flagel- 

 lum equal in length and fully four times as long as thick at apex. 

 Thorax polished laterally and ventrally, subpolished and densely 

 pilose dorsally; pronotal groove, notauli, prepectal furrow and mes- 

 episternal furrow foveolate; metapleurum rugose; propodeum 

 coarsely rugose with a median carina basally and parallel carinae at 

 apex, posterior angles prominent. Abdoment barely longer than 

 thorax, the apical segments strongly retracted ; first tergite broader 

 than long, striate, with prominent dorsal carinae, between which the 

 surface basally is deeply concave; second tergite longitudinally 

 striate throughout, the striae not converging behind; other tergites 

 smooth and polished, second suture not foveolate; sheath about as 

 long as abdomen. 



Black; palpi and legs testaceous; all tarsi and hind tibia brown- 

 ish ; antennae black, piceous at base, wings very dilutely inf umate. 



Type locality. — Duncan, B. C. 



Type.— Cut. No. 41998, U.S.N.M. 



Paratypes. — Two are deposited in the Canadian national collection. 



Four females reared June 8, July 13 and 20, 1928, by W. G. 

 Mathers from a fir tree, under his number 17241, lots 1, 11, and 13. 



MICROBRACON LENDICIVORUS, new species 



Because of the deep foveolate tergal sutures and transverse fur- 

 rows of the tergites it runs in Ashmead's ^ generic key to 4, but differs 

 from the only genus falling there, Glyptomorpha Holmgren, in its 



srroc. U. S. Nat. Mus., vol. 23, 1900, p. 137.
