136 BRITISH ICHNEUMONS. [Hemiteles. 



this species from Dr. Capron's collection, probably taken at Shere in 

 Surrey ; the female has the abdomen somewhat broadly red in the centre. 



17. varicoxis, Tasch.

Head black with the palpi and base of the cheeks white ; face aciculate, 

 clypeus smoother but not discreted. Antennae filiform and apically 

 acuminate, with the joints elongate. Thorax black ; metathorax smooth, 

 with complete areae ; areola hexagonal and basally contracted ; petiolar 

 area nearly vertical, discreted and sub-alutaceous ; apophyses distinct. 

 Abdomen castaneous, with the broad, curved and apically slightly ex- 

 planate basal segment b'ack and the anus white ; post-petiole deplanate 

 and, like the second segment, finely rugose longitudinally, with the 

 spiracles sub-obsolete and the apex glabrous ; third segment except at its 

 apex coarsely punctate. Legs with the front tibiae intumescent; anterior 

 femora and tibiae castaneous with darker tarsi ; apices of the hind femora 

 and their tarsi black, their tibiae piceous and basally white ; trochanters 

 and the anterior coxae-white. Wings slightly clouded below the large and 

 piceous stigma ; radix, tegulae and base of the stigma white. Length, 

 4-7 mm. 



This species is related to H. casianeus, Tasch., in its dull and densely 

 pubescent frons and mesonotum, complete metathoracic areae, evidently 

 antefurcal nervellus, elongate terebra, finely alutaceous second and 

 striolate first segments, but may be distinguished by the colour of the legs 

 and by the more obviously sub-rugose-punctate and red central segments. 



" Das S stimmt in Grosse, Korperform, Skulptur und Farbung ganz 

 genau mit dem $ ; die Skulptur der 3 ersten Segmente ist etwas grober. 

 Fiihler schwarz, Schaft unten mit weissem Fleck. Die 2 letzten vSegmente 

 schwarz-braun. Vorderhiiften mehr rot als weiss. Hinterhiiften schwarz- 

 braun und rot. Hinterschenkel und Schienen ganz rot, letztere ohne 

 weissliche Basis." — (Strobl. igoo). 



This species has only been found in Sweden and Germany, where 

 Ratzeburg bred his very probably synonymous H. coactus from Andricus 

 iermitialis together with his H. punctatus (? Cecidonomus Westoni) and 

 Phygadeuon horiula?ius, Grav. Biorrhiza ierminalis is an oak-feeder, and 

 Schmiedeknecht says he has always taken H. varicoxis on coppice-oaks. 

 It has long stood in our catalogue, but I only know of Bridgman's record 

 of it from Earlham, near Norwich, in July.
