 Angitia gracilis, Schm. Opusc. Ichn. 1778, J ? . 



Head with the vertex transverse, and somewhat constricted behind the 

 eyes; clypeus not basally discreted; teeth of the flavous mandibles ot 

 equal length. Antennae shorter than body, with first flagellar joint 

 slightly longer than second, and sometimes the scape apically flavous. 

 Thorax cylindrical and much longer than high, with the mesopleural 

 punctures running into sinuate aciculation and their speculum nitidulous; 

 metathorax elongate, with discal arcae complete; areola elongate, of 

 variable length, and apically incomi)lete. Abdomen slender and immacu- 

 late black; postpetiole about double breadth of, and about a third shorter 

 than, petiole, laterally ijarallel-sided in (J, slightly roundi'd in 9 ! second 

 segment a third longer than broad; terebra a sixth of the abdominal 

 length. Legs with front coxae of 9 and anterior of (;J , with their trochan- 

 ters except base of hind ones, flavous; femora fulvous with hind ones 

 often infuscate at both extremities ; anterior tibiae .stramineous, hind ones 

 white with their apices and a subbasal mark black. Stigma luteous or 

 piceous; tegulae stramineous; areolet petiolate or subsessile, emitting 

 recurrent nervure beyond its centre; nervellus entire. Length, 3.5-nearly 

 5 mm. 



" It differs from />. viiglnalis,''' says Bridgman, " in its smaller size, and 

 in having the hind femora generally more or less fuscous at the base and 

 apex, the front coxae of the female and front and middle coxae of male 

 yellow ; the post-petiole is slender, rather longer than wide, in vii'i^inalis 

 it is subquadrate with distinctly projecting spiracles; the areola of the 

 metathorax is long and narrow, in the other species it is transverse." 

 ISridgman referred his species to (iravenhorst (LE. iii. 511, (^), but that 

 is now recognised as belonging to the genus JVcncri/is. Schmiedeknecht 

 quotes (Opusc. Ichn. 1685 ct 1778) the latter author under both ! 



Gaulle, who leaves it in Limmritiin in igo8, says it has been raised from 

 Choreutcs and Acrolepia asscctella in France. Bridgman described both 

 sexes from Wimbledon, and both Moushold and Earlham near Norwich, 

 adding that two batches had been bred from Gracilaria stigmalclla. 

 Subsequently Bignell in Devon ai;d Fletcher of Worthing both bred it 

 from Corisciutn cucuUpcnncllum, the latter on 14th August. It is rarer with 

 us than the last species, and by no means easy to distinguish. I have 

 only some half dozen examples, besides a full series taken at Shere by 

 Capron; these are from sallow in Wicken Fen in Cambs., and several by 

 sweeping at Winterton in Norfolk during June; from reeds at Southwold 

 at the end of September, when Tuck took it in Finborough Park, also in 

 Suffolk; and, in the middle of June, Tomlin has sent it me from the 

 Point of Aire.
