A black species with the mouth, epistoma and humeral marks whitish ; 
scutellum more or less broadly at its apex, and the legs, flavous; anterior 
coxae and trochanters paler, with the anterior coxae of ? basally and 
hind ones entirely black ; abdomen centrally fulvous, with the apical seg- 
ments flavous-margined. Length, 4—5 mm. 
A conspicuous and very prettily marked species, known by its broadly 
pale scutellum, utter lack of areolet (in fact one male in Marshall’s col- 
lection has even the submarginal nervure obsolete) and the ¢@ flagellum 
bearing no raised lines; from H. elegans it differs in the vertex being 
short and subangularly emarginate; frons neither shining nor sulcate ; 
mouth white ; ¢ with cheeks broadly pale ; metathorax densely but not 
rugosely punctate, with areae and costae entirely wanting ; scutellum sub- 
triangularly flavescent nearly to its base; postpetiole quadrate, finely and 
subrugosely punctate ; abdomen black with segment three entirely, second 
except basally, and the first at its apex, red; apices of the apical and in 
d central segments flavidous; second subtransverse, broader apically, its 
base not striolate between the distinct and circular thyridii, disc very 
finely punctate; legs slender and flavous with coxae and trochanters 
paler; anterior coxae of 9 basally and hind ones entirely in 9, internally 
in 6, black; hind tarsi dull testaceous ; areolet entirely wanting ; ner- 
vellus intercepted nearly in its centre. 
This species would appear to be rare everywhere; it is found in 
northern and central Sweden (Thomson), in August (Holmgren); in 
France (de Gaulle); and Jacobs and Tosquinet record it from Belgium 
(Ann. Soc. Belg. 1890, p. 125). It was recorded from Lakenham, Earl- 
ham and Brundall, in Norfolk, by Bridgman (Trans. Norf. Soc. 1894, 
p- 629), without any note respecting its novelty as British ; and there is a 
male (named “ gracilentus, Holmgr.”) from Bishops Teignton with two 
females from Bugbrooke in Northants in Marshall’s collection. I also 
possess a couple of males, captured by the late Dr. Capron at Shere in 
Surrey; but have not met with this species myself.

Head as broad as thorax and a little constricted posteriorly ; vertex 
somewhat short and subangularly emarginate centrally ; frons somewhat 
dull and not sulcate; face laterally parallel; epistoma with a central 
oblong stramineous mark in 9, face and frontal orbits nearly entirely 
pale with cheeks black in @; clypeus slightly emarginate centrally with 
its hardly depressed sides and the palpi pale testaceous; mandibles 
entirely pale, basally almost shorter than the cheeks and apically con- 
stricted. Antennae reaching almost beyond thorax; flagellum ferru- 
gineous in 9, darker in @, with scape and pedicellus black and beneath 
mainly testaceous, Thorax with large pale testaceous mesonotal humeral
