62 Mr. Ernest A. Elliott and Mr. Claude Morley on the 
also larvee of Clerus formicarius, but they could not have 
been the host”—one wonders why not, since their size 
would appear more appropriate than that of this Cryptid. 
The same observer also found Bracon stabilis (iii, 38) and 
Celoides filiformis (111, 72) associating with this borer in 
ash bark. Ps 
247. Hylesinus fraxini, Panz. 
Feldjager Angern, in his observations on timber and its 
injurious insects, bred Spathius ewannulatus“" (Ichn. d. 
Forst. 11, 43) out of this species, as also did Nordlinger at 
Hohenheim on July 3rd a single f of Celoides melanotus 
Gi, 40). All its other parasites were, however, Chalci- 
didous: Oberforster Radzay raised fourteen specimens of 
EHurytoma flavovaria (i, 173) from Hylesinus fraxini in ash, 
where they pupated in such a manner as to easily emerge 
through the beetles’ orifice; with it he bred several ¢ f of 
EL. ischiovanthos (i, 174), some spotted-winged Pteromali 
and Styloceras ladenbergi ** (1, 208). From borings of the 
same species, Saxesen once bred a single Lurytoma flavo- 
scapularis (i, 173) ; and from its larve, Radzay raised 
Pteromalus fraxini, P. bivestigatus, P. binimbatus*" and a 
gd P. bicaliginosus** (1, 190-191). Angern also found one f 
Tridymus xylophagorum (ii, 184) among a mass of Ptero- 
malus bimaculatus which had emerged from this borer, as 
well as Sciatheras trichotus*® (11, 209) and a single Lupelmus 
geert Gli, 151); Hurytoma nodulosa is also indicated (ii, 
215) as preying upon this beetle. Giraud adds Dendro- 
soter protuberans, Cerocephala cornigera and also bred in 
France Celiodes filiformis, C. melanotus, Eurytoma flaveo- 
laria, Raphitelus ladenbergi®® and Pteromalus bimaculatus, 
Spin., from this host. In May 1906 Mr. Donisthorpe bred 
a 2 Cheiropachus quadrum at Enfield from a pupa of 
H. fraxini, together with both sexes of Bracon caudatus, 
Ratz., and of B. longicaudis, Ratz., of which the latter is 
new to the British fauna. The same observer also bred, 
at the same time and from the same beetle, a species of 
Pteromalus at Leighton. 
248. Huylesinus oleiperda, Fab. 
Fonscolombe, quoted by Westwood (Mod. Class, 11, 159), 
tells us that Cheiropachus quadrum also feeds upon the 
larvee of this beetle; and Dr. Ratzeburg (Ichn, d. Forst.
