490 Messrs. E. A, Elliott and Claude Morley on the 
and Mayr says (Verh. z.-b. Ges. 1879, p. 322) that he 
also bred from it on Pinus nigricans in January and 
February the latter's Zurytoma auricoma, near Vienna. 
253. Hylurqus piniperda, Linn. 
Cooper's parasitism was entirely supposititious (¢/, loc. cit.) 
and he gives C. pulchellus as a MS. name of Walker. 
Perhaps one of the Chalcids already mentioned is synony- 
mous with MHartig’s inadequately described Diplolepis 
hylesinum (Forstl. Conversationslex. 1834, p. 198), which 
he bred from the same host in Germany. Dalla Torre 
gives no authority for his statement (Cat. Hym., iii, 604) 
that this species is also attacked by Spilocryptus incu- 
bitor, Strom., which is most improbable. We have seen 
a 2 of Bracon minutator, Fab., bred by Mr. G. H. 
Grosvenor at Vaumoise, early in October, from galleries of 
this beetle. 
253a. PHLOEOTRIBUS FRONTALIS, Oliv.* 
A Chalcid, named by him Secodes phloeotribi, has been 
bred by Ashmead from this borer in Virginia (Trans. 
Amer. Ent. Soc., 1896, p. 233), together with his Cecidostiba 
dendroctoni (1. ¢., 1894, p. 338) and his Hurytoma phloeotribi 
(1. ¢., p. 326). 
254a, PHLOEOSINUS DENTATUS, Say.* 
A new species of the genus Huwrytoma has been described 
as preying upon this beetle by Ashmead (Trans. Amer. 
Ent. Soc., 1894, p. 327) in Virginia, under the name 
L. phloeosini. 
2550. POLYGRAPHUS RUFIPENNIS, Kirby.* 
From this species Ashmead has bred in Virginia both his 
Cecidostiba dendroctoni and his C. polygraphi (Trans. Amer. 
Ent. Soc., 1894, p. 338). 
2558. HYPOTHENEMUS ERUDITUS, Westw. 
Chittenden has observed that Cephalonomia hyalini- 
pennis, Ashm., attacks this cosmopolitan species in Florida 
(Kief., Proct., i, 237).
