142 BRITISH ICHNEUMONS. [Hemiteles. 



Hammer, and Marshall (the only S I have seen) from Cornworthy, near 

 Totnes. The second variety is represented in my collection by a female 

 taken by Capron, probably at Shore, and a male by Marshall at Govilon, 

 near Abergavenny. Of the third variety I have but a single female, also 

 from among Marshall's unnamed specimens, from Botusfleming in Cornwall. 

 The micropterous form (Pez. sn/'zo/tatus) has not before been associated 

 with H. crassicornis, and only four examples have come under my observa- 

 tion ; one captured by Willoughby Ellis in Sherwood Forest and another 

 by E. A. Butler at Wymondley in Hertfordshire ; Piffard has found one at 

 Felden in Herts, and in the middle of September, 1898, I took it in a crag 

 pit at Foxhall, near Ipswich. 



21. contaminatus, Grav. 



Hei/ii/eles corifaifiiiiatiis, Gr. I. E. ii. 840; Schm. Term. Ftiz. 1897, p. 516,9. 



Head with mouth stramineous. Antennae slender, filiform and rather 

 shorter than body, with the joints cylindrical and not discreted ; infuscate, 

 basally testaceous and centrally broadly white-banded. Thorax sub- 

 cylindrical. Abdomen fusiform, distinctly petiolate, slightly narrower 

 than the thorax and apically truncately compressed ; black with margin of 

 first two segments rufescent and of the last stramineous ; basal segments 

 bottle-shaped, with post-petiole as long as petiole and twice longer than 

 broad ; terebra hardly length of half abdomen and obliquely reflexed. 

 Legs slender, entirely pale flavidous. Wings ample and hardly clouded ; 

 stigma dark testaceous, tegulae red, radix pale stramineous. Length, 4 mm. 



We here have a good example of the value of Taschenberg's revision ; 

 he makes no mention of the present species, which consequently no one 

 has recognized from Gravenhorst's description, translated above. The 

 original single female transmitted to Gravenhorst from Piedmont still 

 remains unique, excepting, of course, for the supposititious British speci- 

 men or specimens brought forward by Marshall in his 1870 Catalogus 

 and repeated in 1872.

Hemiteles incisus, Briflg. Trans. Ent. Soc. 1883, p. 150, 9 ; Thorns. O. E. x. 987, (5-9 . 



Head somewhat nitidulous, of S dilated behind the eyes ; frons finely 

 and somewhat sparsely punctate, transverse ; face slightly narrower above 

 than below ; mandibles not tuberculate, of $ black. Antennae of S 

 black, of $ rather longer than half body, filiform, with scape red ; two 

 basal flagellar joints red, of equal length and four times longer than broad, 

 following becoming shorter. Thorax as broad as head and slightly longer 

 than high ; mesonotum dull and pubescent, centrally scabriculous an- 

 teriorly and aciculate posteriorly ; notauli distinct but not deeply impressed, 

 extending to centre, with lateral lobes nitidulous and distinctly though not 

 very closely punctate ; metathorax nitidulous and rugose with the transverse 

 costae prominent, but the longitudinal indistinct ; areola irregularly hexa- 

 gonal, twice broader basally ; petiolar area entire, apophyses sub-acute. 

 Scutellum smooth and shining, sparsely punctate. Abdomen smooth and 

 shining with scanty pul)escence ; the segments transverse with very distinct 

 incisures, the second to fourth and a[)ex of the first brunneous ; basal
