CONTRIBUTIONS TO OUR KNOWLEDGE OF THE BRITISH BRACONIDS. 7 
tarsisque posticis nigris; tibiis posticis albidis, macula ante basin 
apicique fuscis; primi segmenti abdominis tuberculis lateralibus 
acute prominulis (coxis posterioribus rufis; terebra corpore paulo 
breviore, ° ). 
The terebra is very slightly shorter than abdomen and 
thorax combined; the hind coxe are rufous in the female but 
black in the male; wings hyaline at base, darker towards 
apex. Antenne 30-31-jointed. In some examples the nervure 
dividing the first cubital and first discoidal cells, though always 
traceable, is indistinct, which adds to the structural resemblance 
the species bears to Microdus tumidulus ; there can be no doubt, 
however, that it is a true Harinus, the mesothoracic sutures 
being almost indiscernible. 
Not before recorded as British and possibly hitherto confused 
with delusor (gloriatorius, Marsh). I have found it fairly common 
in the New Forest, where on dull, damp days in April and early 
May I have on many occasions beaten both sexes from the 
leafless, lichen-covered branches of oak trees. 
Genus 5... Orgilus, Hal.* 
Authors have taken somewhat divergent views as to the 
true position of this aberrant genus, and although the majority 
consider it rightly placed with the Agathide, there is no doubt 
that considerable affinity is shown to the Macrocentride, as 
noted by Haliday, and also to the genera Hubadizon and 
Pygostolus. i am rather inclined to agree with Ashmead,+ who 
based his Orgilini, a tribe of his Blacine, on the genus, placing 
it immediately before Hubadizon. Szépligitit did not agree with 
the American classification and restored the genus to its old 
position. 
Maxillary palpi 6-, labial 4-jointed. Face ordinary; mesopleure 
with a crenulate furrow ; mesothorax distinctly trilobed. Wings 
short, narrow, stigma somewhat elongate, two cubital cells, the first 
distinct from the first discoidal ; radial cell narrow, though much 
larger than in the preceding genera, ending much before apex of 
wing; first intercubital nervure almost in a line with the second 
(third) abscissa of radius.
