Very similar to Z. nigripes, but rather less nitidulous with the facial 
pilosity infuscate, frons more strongly and closely punctate, clypeus but 
slightly convex basally ; antennae apically pale beneath ; metanotal areae 
always complete, rugose, with areola elongate and laterally parallel ; scu- 
tellum deplanate, and laterally margined to its centre; segments two to 
four only usually red, and in ¢ somewhat dull; basal segment punctate, 
subimmarginate, with carinae extending beyond its centre; hind tibiae 
pale, with their apices alone nigrescent. Length, 6—10 mm. 
Not uncommon on the Continent from Sweden to France and bred by 
Brischke in Prussia from a Dolerus larva. Rev. T. A. Marshall possessed 
specimens from Nunton in Wilts and Govilon in south Wales. Capron 
took a full series in at Shere, Beaumont found it at Chobham Surrey, 
Thornley at Tresswell and South Leverton in Notts and Kelsey in Lincs., 
Miss Chawner several in the New Forest, where alone it has occurred to 
me at Matley Bog and Lyndhurst, and Rev. E. N. Bloomfield has given 
me amale named by Bridgman from Guestling in Sussex. I have no 
records from the northern counties.

This species differs from the last two in its much finer and more diffuse 
frontal puncturation, in its mainly rufescent hind tibiae, more strongly 
convex clypeus and distinctly margined basal segment; the metanotal 
areae are basally entire; and Thomson adds that the median nervure is 
parallel with the posterior in this species, whereas it is basally convergent 
therewith in Z. consobrinus, which has the epicnemia emarginate and 
female valvulae black, while in the present species the former is centrally 
entire and the latter flavous. Length, 6—9 mm. 
As broadly distributed as the last species and not easy to distinguish 
therefrom. With us its distribution is much broader, though it has not 
been mentioned since introduced by Marshall, who possessed no 
specimens, in 1870. I have examples captured at Cannock Chase in 
June by Tomlin, at Cadney in Lincs. by Thornley, at Tostock in Suffolk 
in June and July by Tuck, at Glengariff in Co. Kerry in June, 1901, by 
Yerbury; at Ballater, Banchory and Birnam in Perth in August by 
Elliott; and at Whiting Bay in the Isle of Arran in September, 1903, by 
Waterston. I have taken but a single pair; the female was investigating 
flowers of the blue wild hyacinth in Bentley Woods on 26th May, 1904, 
and the male was upon the flowers of Lupatortum cannabinum on 14th 
June, 1900, at Glemsford in Suffolk. Another was sucking /Herac/eum in 
my paddock at Monks’ Soham in July, 1908. That the female of this 
species is at least locally most constant in colouration and frontal sculp-
