There has, however, resulted but one addition to our fauna from the 

 twenty species there recently described.

Somewhat shining, rugosely punctate, with fuscous pilosity. Head 

 coarsely punctate and pilose, black ; face flat and uniformly alutaceous ; 

 clypeus deflexed, incompletely discreted and apically slightly rounded, 

 with a central impression ; $ palpi white. Antennae black, slender, as 

 long as body, with the lower flagellar joints sub-discreted and apically 

 tumidulous ; of $ with first flagellar joint about thrice longer than 

 broad ; of $ centrally white-banded and a little incrassate before the 

 apex. Thorax coarsely punctate and pilose ; metanotum more coarsely 

 punctate in $, its lateral areae incomplete; the petiolar entire, broad, 

 sub-vertical and longitudinally strigose, with, in 9 , its basal margin 

 sub-obsolete ; basal area of $ smooth ; spiracles linear, broader in $ . 

 Scutellum black. Abdomen narrower than thorax, elongate-ovate and 

 in $ sub-linear ; castaneous-red, with first segment or only petiole, 

 apical half of fourth, and whole of the remainder, black ; post-petiole 

 glabrous, somewhat convex, a little longer than broad, with no foveae 

 nor furrow, and sides straight to close to apex and spiracles prominent ; 

 terebra one-third the length of the abdomen. Legs black ; anterior 

 tibiae and tarsi, apex of front femora and base of hind ones, usually 

 testaceous ; hind tarsi of $ with apex of first and whole of second to 

 fourth joints white, of ? with third and fourth apically dull white ; the 

 $ anterior trochanters also sometimes white-marked. Wings a little 

 clouded ; radix and tegulae infuscate ; radius apically reflexed, nervelet 

 elongate, areolet sub-quadrate ; nervellus intercepted slightly below the 

 centre. Length, g-12 mm. 



Marshall says Gravenhorst's description does not apply to the Linnaean 

 type, and Thomson that his female is distinct from that of Gravenhorst, 

 who seems to have described more than one species under this name ; 

 but if this be so, the discrepancies are so trivial — the colour of the third 

 segment and slightly paler anterior legs — as to be quite inconsiderable. 



Bouche gives us a somewhat meagre description of the larva and cocoon 

 of this s[)ecies (Naturg. 142). The former is cylindrical and curved, with 

 inflated lateral margins, it is white and acuminate with isolated bristles ; 

 the rounded head bears two short, turbinate antennae, and the dorsal 

 segments are rather humped, with the last one narrowed ; its length is two 

 lines. He adds that it preys upon the larvae of Bolys samhucalis ; that
