ONE ix. 904-0 oar 
A punctate species, a little shining and black, with the legs alone red. 
Head not constricted posteriorly and somewhat nitidulous ; clypeus dis- 
tinctly discreted, apically rounded and red; frons strongly and not 
closely punctate; face punctate and prominent below the scrobes. 
Antennae often apically rufescent beneath. Thorax as broad as the head, 
stout, punctate and somewhat shining ; pleurae not dull and apically sub- 
punctate; metathorax short, rugulosely punctate with five very distinct 
discal areae. Abdomen a little longer than head and thorax, entirely 
black, with the three basal segments dull, finely rugose and subparallel- 
sided; basal segment convex, margined, finely and rugulosely punctate, 
with carinae extending nearly to its apex; second obliquely impressed 
basally on either side. Legs stout and red with coxae and trochanters, 
except extreme apices of latter, black. Wings with radial nervure a little 
reflexed apically; nervellus intercepted below its centre. Length, 
5—6 mm. 
At once known from the remainder of the genus by its dull abdomen, 
with the three basal segments finely and rugulosely punctate. 
This distinct species has been found in Sweden, Lapland, Prussia and 
France. It has not before been noticed as British, but I possess a single 
male, which I took by sweeping herbage at Eaton near Norwich on 9th 
June, 1901; and there is, I believe, another in the Edinburgh Museum.

Punctulate, sericeous and somewhat shining, black with the clypeus 
apically red. Antennae a little longer than half body, black and rarely 
ferrugineous basally. Thorax gibbulous; metanotum with five very dis- 
tinct discal areae. Abdomen black with only the apical margins of seg- 
ments discally red; basal segment margined, not convex, nearly smooth, 
with carinae extending to its centre ; second segment obliquely impressed 
on either side at its base. Legs stout and red with the coxae and tro- 
chanters, except extreme apices of latter, black; tibiae often basally 
flavidous. Wings with stigma infuscate and tegulae testaceous ; areolet 
small, irregular, obliquely transverse and petiolate or subpetiolate or sub- 
sessile ; nervellus intercepted below its centre. Length, 5—6 mm. 
This species is very like 2. punc/ulafus, but much more finely punctate 
with the abdomen discally smoother. Woldstedt in 1877 synonymises 
with it Zryphon haemorrhoicus, Htg. (Jahresb. 1838, p. 27; Ratz. Ichn. d. 
Forst. i. 129, 2), but both were known to Brischke, who considers them 
distinct under the present genus in 1878; the latter has been bred from
