ART. 4 NEW PARASITIC HYMENOPTERA GAHAN 7 



recorded the species from Hawaii. The National Collection shows 

 that it occurs from New Jersey and North ^^arolina to California in 

 North America. Apparently the species is nearly cosmopolitan. 



Kurdjumov placed Boheman's species in the genus Lariophagus 

 Crawford but stated that it was a form transitional to Mormoniella. 

 His conclusion was based on specimens determined by Gustav Mayr. 

 Kurdjumov noted some variation in these specimens as regards the 

 development of the occipital carina. In all of the many specimens 

 of the species that have come under my notice this carina is present 

 though varying to some extent in its development. 



Mormoniella is very similar to Lariophagus but the two genera 

 may be separated by the following dichotomy: 



Occiput with a carinate margin; funicle joints in female all broader than long; 

 parapsidal grooves sharply defined on anterior two-thirds of mesoscutum; 

 scutellum with a fine but more or less distinct cross furrow before the apex; 

 propodeum about two-thirds as long as scutellum, terminating in a distinct 

 short neck, without a transverse carina, the lateral folds distinct and a 

 delicate median longitudinal carina usually present; head, mesoscutum, and 

 scutellum with a shallow reticulate-punctate sculpture and shining 



Mormoniella Ashmead. 



Occiput entirely immargined; funicle joints not all broader than long; parapsidal 

 grooves very weakly impressed at anterior angles of mesoscutum; scutellum 

 without a cross furrow; propodeum less than half as long as scutellum, 

 without a neck, with distinct transverse and median longitudinal carinae, 

 the lateral folds distinct; head, mesoscutum and scutellum with fine deep 

 punctation, opaque Lariophagus Crawford. 



CECIDOSTIBA ACL'TUS (Provancher) 



Dijwtus acuttis Provancher, Add. Faun. Can. Hym., 1887, p. 201. 

 Cecidostiba ashmeadi Crawford, Proc. U. S. Nat. Mus., vol. 43, 1912, p. 170. 



A specimen agreeing with Provancher's description in every respect 

 and said to have been reared from PolygrapJius rujipennis in the 

 province of New Brunswick, Canada, was recently received from H. 

 L. Viereck. This specimen was compared with the type of Cecido- 

 stiba ashmeadi Crawford which was described from specimens reared 

 from the the same host species at Morgantown, West Virginia, and 

 found to agree. 



Family EURYTOMIDAE 



NEORILEYA MERIDIONALIS, new species 



Similar to the male of N. jlavipes Ashmead but readily distin- 

 guished by the narrower face and the absence of any large punctures 

 on the last visible tergite. Differs from the description of alhipes 

 Girault in lacking any trace of a fuscous spot appended from the 

 stigma and by the absence of any median carina on the second tergite. 



Male. — Length 2 mm. Head as broad as thorax, viewed from 

 above approximately two and one-half times as broad as long at
