Hymenopterous Parasites of Coleoptera. 31 
Reissig and Brischke from swollen aspen twigs containing 
these larve in May, June and July (iii, 70); Pteromalus 
zneicornis, several raised by Brischke out of aspen 
swellings whence the 4. Gedanensis had already emerged 
(iii, 228); with, doubtfully, a single Entedon chalybeus 
from a similar larval swelling in poplar by Reissig, and 
Torymus macrocentrus by Nérdlinger at Stuttgart out of 
similar knots in a weak aspen (iii, 224) ;—were all noted 
from Cerambyx populneus by Ratzeburg (lid. cit. 11, 212 et 
ili, 249); as also was said by Brischke to have been 
Ichnewmon suspicax? (iii, 166), but Morley regards this 
(Ichn. Brit. i, 248) as “almost certainly in error,” and adds 
(1. ¢. 292), “a great deal more proof is needed before any 
reliance can be placed upon the records of any Ichneu- 
moninz preying upon Coleoptera.” Tischbein once saw 
Glypta teres,” Ratz. [nec Grav. : cf. Thoms., Opuse. Ent. xiii, 
1340] swarming round an aspen and several times bred 
the same species from the present Longicorn. Brischke, 
in his Prussian Ichneumons, also gives Hphialtes continwus, 
Ascogaster lxvigator %* and Entedon chalybeus, adding 
Diadromus subtilicornts with a query. Giraud records 
(Ann. Soc. Fr. 1877, p. 397 et seqg.) Cryptus analis,* 
Ephialtes tuberculatus, Pimpla alternans, Kchthrus nu- 
beculatus, HL. populneus, Gir., and Bracon denigrator,” Fab., 
as preying upon it. Kirchner (Cat. 119) adds Chelonus 
nigrinus and Tosquinet (Ann. Soc. Belg. 1897, p. 280) 
Ephialtes carbonarius, upon 'Taschenberg’s authority. 
Bridgman says (Trans. Norf. Soc. 1893, p. 629) that Mr. H. 
J. Thouless has bred both Lphialtes imperator and £. 
tuberculatus from this Longicorn in Norfolk. 
106. Saperda scalaris, Linn. 
According to Dr. Laboulbéne (Ann. Soc. Fr. 1877, p. 
405), Perris bred Campoplex transfuga, Gir., Orthocentrus 
fulvipes, Grav., and Meteorus tabidus, Wesm., from this 
species; from which has also been raised (Ann. Soc. Belg. 
1897, p. 822) by Dr. Fromont Xylonomus filiformis, Grav., 
in Belgium. Nérdlinger also bred both sexes of 2%. 
precatorius (Ichn. d. Forst. 111, 115) from a Cerambyx + in 
maple. 
1 Ratzeburg (loc. cit.) calls this beetle Ceraimbyx luridus ; I fancy, 
however, it is really Saperda scalaris, as Tetropiwm lwridum lives in 
Coniferx.—K. A. KE.
