[March, 
Face, and sides of the thorax partially, aciculated. Abdomen nigro- 
piceous ; of the ? , often reddish beneath. Wings hyaline, nervurea 
reddish-brown. ^ ? . Long. 1— li ; alar. esp. 3|— 4i lin. 
Var. a. With a fulvous patch on each side of the thorax, before the ' 
tegulse. 
Var. h. With a fulvous patch as in var. a, and with the disc of the 
mesothorax and scutellum variegated with fulvous or testa- 
ceous. An extreme example of this variety is described, by 
mistake, on p. 101, as Andricus Rartigii. That name must 
be suppressed, and the description considered as referring to 
this place. 
Not to be confounded with Cynips ruU, Schrank, Ina. Austr., p. 
320, No. 646, which is a Callimome, probably parasitic in the bramble- 
gall. Another parasite is Eurytoma habrotani. 
B. rubi forms the strumous enlargements frequently seen on the 
stems of Ruhus ccesius. These galls are figured by Eeaumur, Ins., t. 3, 
pi. 36, f. 1—5. rig. 4 represents the larva magnified ; it has two oval 
brown spots on the last segment but one. 
Beside the preceding, two other species of Biastroplius have been 
described ; D. aceris (Forst), Kaltenbach, Ver. nat. Ver. d. pr. Eheinl., 
1856, p. 171 ; and B. scahiosce, Giraud, Verb. Zool. bot. Gesellsch. 
Wien, 1859, p. 368,— which are both likely to be found in this country. 
Genus Spathegastee, Hartig. 
Antennae ^ 15-jointed, longer than the body, slender, filiform ; 
3rd joint nearly twice as long as the 4th ; 4 — 14 gradually decreasing 
in length, 14 and 15 equal, the latter acuminated ; of the ? 13-jointed, 
hardly longer than the head and thorax ; 3rd joint as in the (J , 4th 
longer than the 5th, 6 — 13 much shorter, and gradually incrassated to 
the apex. Mesothorax convex, gibbous, hardly shining, sub-coriaceous, 
with three obsolete longitudinal sutures ; at each hinder angle is a 
foveola. Scutellum separated from the mesothorax by a wide, sinuated 
depression ; oblong, sub-coriaceous, faintly margined, hardly shining. 
Metathorax nearly perpendicular. Petiole of the (J one-third as long 
as the hind coxae ; of the ? very short. Abdomen of the $ much 
compressed, the dorsal ridge rising above the scutellum; viewed 
laterally, sub-orbicular, truncated behind ; ovipositor hardly exserted. 
Abdomen of the S > viewed from above, linear, compressed, much smaller 
than that of the ? , its dorsal ridge not rising nearly as high as the 
scutellum ; viewed laterally, spatliuliform, its upper edge convex, the 
lower edge straight. Wings as in Neuroterus.
