156 BRITISH ICHNEUMONS. [Glypta. 



This species diifers from G. teres in its transverse central abdominal 

 segments. I follow Thomson in synonymising G. resinanae Avith G. 

 consimilis of Holmgren, although in a note (O.E. 2128) he says that 

 Holmgren's Glpyfae were so entirely incorrectly named that he could 

 gain no information therefrom respecting G. teres, consimilis and other 

 species. 



Bred from Retinia resinana in Prussia by Brischke ; and at Kings L\nn 

 in Norfolk by Atmore, as well as by Barrett, from Retinia turionanae 

 (Trans. Norf. Soc. v, p. 72), Kirchner also mentions the latter host on 

 the Continent (Cat. 102). I have seen a female of this species, taken at 

 Charlbury in the middle of June, by Hamm. Bridgman records (Entom. 

 1884, p. 71) G. consimilis as bred from Ephippiphora scutiilana by Fletcher 

 of Worthing. Bankes has given me a male bred at Brighton in 1906, 

 from Parasia metzneriella, Stt. ; and I possess two females, found by Tuck 

 at Tostock in Suffolk and ]Miss Alderson at Thorne in Yorks, differing in 

 nothing but the terebral length which is not greater than that of the 

 abdomen.

A linear, black and shining species. Head of 9 shorter and more 

 strongly constricted behind the eyes than in ^ ; frons punctate with a 

 transverse, subrugulose impression above the scrobes, but no horn ; labrum 

 dull ferrugineous, palpi subtestaceous ; clypeus not covered with dense 

 pubescence. Antennae subfiliform, apically attenuate, black ; of 9 half 

 the length of, of ^ nearly as long as, the body ; often ferrugineous 

 beneath. Thorax cylinidrical and immaculate ; metanotum strongly 

 punctate, with five subcomplete areae, of which the areola is hexagonal 

 with the base and apex truncate. Abdomen narrow, cylindrical, alutac- 

 eously punctate and dull, a little longer and narrower than the head and 

 thorax ; the three basal segments or only the second and third rarely with 

 the incisures rufescent, the latter never broader than long ; basal segment 

 laterally marginate, with distinct carinae hardly extending beyond its 

 centre and the apical angles obtuse ; terebra as long as, or slightly longer 

 than, abdomen with the spicula castaneous. Legs somewhat slender, ful- 

 vous-red with the coxae and base of the trochanters black ; the slender 

 hind tarsi entirely and apices of their tibiae infuscate, the latter generally 

 basally pale with calcaria of equal length. Wings normal, hyaline with 

 the radix stramineous, stigma subtestaceous and the tegulae infuscate or 

 red. Length, 5 — 7 mm. 



The S differs in having the antennae as long as the body, infuscate 

 with the under side ferrugineous, the legs paler and the abdomen a little 

 longer. 



That Gravenhorst's second and third varieties belong to this species is 

 doubtful, since the former is three and three-quarter lines in length with 

 the hind tibiae basally flavescent and the antennae not paler beneath ; 

 and the latter is more slender than the typical form with the mouth, 

 stigma, tegulae and legs stramineous-testaceous, the apices of the hind 

 femora and a band before the white bases of their tibiae nigrescent ; his 

 fourth variety, a 9 > has the mouth subtestaceous, antennae not paler
