l62 BRITISH ICHNEUMONS. [Hemiteles. 



50. meridionalis, Grav. 



Hemiteles vieridionalis, Gr. I. E. ii. 834 ; Schm. Term. Fiiz. 1897, p. 538, ? ; cf. 

 Tasch. Zeits. Ges. Nat. 1865, p. 128. 



Head with palpi and mandibles stramineous ; clypeus discreted and 

 apically rounded. Antennae slender, filiform, shorter than body \ infus- 

 cate or ferrugineous, darker above with scape red beneath. Metathorax 

 reticulate with areae entire ; areola regularly hexagonal, apophyses small 

 and acute. Abdomen oblong-ovate, as broad as thorax ; black, with 

 second, base of third and apex of first segments, red ; basal segment 

 aciculate, gradually dilated apically, nearly thrice longer than broad ; 

 second punctate ; terebra hardly longer than a quarter of the abdomen. 

 Legs normal, red ; hind ones sometimes with tarsi and apices of tibiae, 

 occasionally also of femora, infuscate. Wings hyaline, stigma infuscate ; 

 radix and tegulae white. Length, 5 mm. 



I should certainly expect there to be some error in the inclusion of 

 this species in the British fauna, since it is only known on the Continent 

 from Geneva, had not Bignell captured it at Bickleigh in Devon, on 

 6th September (Trans. Devon. Assoc. 1898, p. 486). 



51. macrurus, Thorns. 



Hemiteles macrurus. Thorns. O. E. x. 985 ; Schm. Term. Fliz. 1897, p. 536, 9 (? (J )• 



Black. Head narrowed behind the eyes with vertex not broad, frons 

 dull and pubescent, clypeus not discreted but apically rounded, mandibles 

 narrowed apically and not tuberculate. Antennae stout, filiform, with 

 scape shortly cylindrical and a little excised apically. Mesonotum some- 

 what dull ; metathorax smooth with costae complete. Abdomen centrally 

 dull, testaceous ; petiole slender with spiracles somewhat far behind centre ; 

 epipleurae of third segment not inflexed ; terebra as long as abdomen. 

 Legs stout. Wings with stigma pale, emitting radial nervure from its 

 centre ; areolet with outer nervure elongate ; nervellus antefurcal. 

 Length, 4 mm. 



This species is very like H. similis, but the antennae are longer, the 

 terebra as long as abdomen, the epipleurae of second segment narrow, 

 with spiracles far from the margin and the much longer external nervure of 

 the areolet, will render it distinct. 



This species, which is found in Sweden and Hungary, claims a position 

 in our fauna upon the somewhat slender right of a female, said to have 

 been taken in the London district in August, 1889, which was exhibited at 

 a meeting of the South London Entomological Society in March, 1890.

 pilose. Antennae filiform and very little shorter than the body ; of ?
