Hymenopterous Parasites of Coleoptera. 467 
97. Exocentrus pwnetipennis, Muls.* 
The “ Braconid,” formerly referred to, appears to be 
Laelius bipartitus, Kief. (Proct., 1, 235) and Blacus 
exocentrt to be a MS. name, as were so many of those 
given by Dr. Giraud in his posthumous paper of 1877.1 
102a. MONOCHAMMUS SCUTELLATOR, Say.* 
1028. MONOCHAMMUS CONFUSOR, Kirby.* 
Upon both these American species Provancher has 
recorded (Fauna Entom. Canada, Hym., 1883, p. 447) the 
parasitism of our British Rhyssa persuwasoria, which with 
us invariably confines its attacks to the Siricidae. J, 
resutor, Kirby, synonymous with the former host, is said 
by Westwood (Trans. Ent. Soc., 1851, p. 224) to be attacked 
by his new Evaniid, Aulicus resutorworus. 
105. Saperda populnea, Linn. 
Mocsary, according to Dalla Torre (Cat. Hym., 111) has 
also raised Cryptus viduatorius, Ephialtes luteipes and 
Xylophrurus lancifer from this species; and Mayr appears 
satisfied (Verh. z.-b. Ges. 1874, p. 101) that the ? of 
Torymus quercinus, Boh. (= T. tarsalis, Walk.), was bred 
from it by Tschek in Austria. 
106. Saperda scalaris, Linn. 
Dr. Rudow records (Entom. Nachr., 1881, p. 310) his 
new Coleocentrus scutellaris as parasitic upon this species, 
106a. SAPERDA DISCOIDEA, Fab.* 
Harrington says (Canad. Entom., 1891, p. 152) that his 
new Canadian Xorides caryae was ‘bred from this species 
1M. Jules de Gaulle, the learned author of the recent full 
Catalogue of French Hymenoptera, has been good enough to write 
me concerning Giraud’s insects: ‘*La collection Giraud est au 
Muséum de Paris ; ; elle est Wun grand intérét, mais Giraud avait 
le tort de travailler seul et parait n’avoir eu guére de relations avec 
les ichneumonologistes de son temps ; la collection est elle vemplie 
de noms inédits, qui pour la plupart s’appliquent 4 des espéces soit 
déja décrites soit surtout décrites depuis sa mort. En outre les 
localités sont rarement indiquées; les espéces proviennent le plus 
souvent d’Autriche.”—(C. M.)
