Hymenopterous Parasites of Coleoptera. 475 
149a, SERROPALPUS.* 
From an unidentified species of this Heteromerous 
genus, Erné records (Mitt. Schweiz. Entom. Ges., 1876, 
p- 518) the breeding of Rhyssa persuasoria, Linn.; but we 
suspect some error here, since this parasite has hitherto 
only been raised from Siricidae in Europe. 
150a. PYTHO DEPRESSUS, L. 
Professor Beare has given me two 29 Ichnewmon con- 
Jusorius, Grav., which he took on April 1, 1907, at 
Aviemore, beneath the bark of a fallen Scots fir among 
larvae of this beetle. No association was, however, estab- 
lished, and the parasite was probably no more than passing 
the winter in its normal hibernaculum.—(C. M.) 
1508. MORDELLA. 
Thomson writes (Opusc. Ent., 2229) of Microdus caleu- 
lator: “Funnen vid Ringsjon i Skane, der den triffades 
pa stubbar hvarur Mordella flégo ut.” 
15la. MORDELLISTENA PARVULA, Gyll. 
Ascogaster armatus, Wesm., and Entedon zanara, Walk., 
are both said to have been bred by Perris from J. 
inaequalis, by Dours (Cat., 78, 109). 
156. Attelabus curculionoides, Linn. 
Chaetostricha (Ophionewrus) signata, Ratz., is also given 
as preying upon this species by Dalla Torre (Cat. Chal., 4). 
156a. ATTELABUS BIPUSTULATUS, Schonh.* 
Howard tells us in his Descriptions of North American 
Chalcids (p. 19) that Aphycus annulipes, Ashm., has been 
raised in Florida from this weevil. 
157. Byctiscus betuleti, Fab. 
“Dr. Filippi (Annals and Magazine of Natural History, 
1852) observed in certain eggs of Rhynchites betuleti a 
smal] parasite like an infusorium, provided with a tail,
