TENTHEEDOPSIS IGNOBILIS. 107 



Very similar in coloration to ignobilis y but larger 

 and stouter, antennae and spurs longer, antennal fovea 

 deeper, clypeus yellow and not so transverse at the 

 apex, and abdomen with only three red segments, 

 which are marked with black in the middle. 



Rare ; two specimens in Shuckard's collection.

Tenthredopsis ignobilis, Cam., Tr. Ent. Soc., 1881, 567. 



Black ; labrum, a thin line on inner side of eyes and a spot behind, 

 and scutellar spots white ; the second to sixth abdominal segments and 

 legs bright red; coxae, trochanters, base, and apex of hinder femora 

 black ; hinder tarsi fuscous, the second to fourth joints paler. Antenna3 

 black, pale on under side ; a dull reddish splash on each of the middle 

 lobes of mesonotum. Wings hyaline; costa pale; stigma fuscous at 

 apex. 



Length 4 5 lines. 



The second segment is usually only black on basal 

 half above, and the red colour sometimes extends to 

 the last segment. The white on the head is generally 

 very obscure, and the white mark behind the eyes may 

 be invisible. It is a broader insect than scutellaris, 

 and the abdomen is more inflated. 



I have only seen three specimens of this species, 

 two from Eannoch, and one from Inverness-shire. 



Continental distribution : France, Germany, Switzer- 

 land (?) 



Obs. It is doubtful if this species is either ignobilis, Kl., or stigma, 

 Lep. The latter is quoted as a synonym of ignobilis by Hartig, but the 

 description will fit several species. Ignobilis is a true Tenthredo accord- 

 ing to Thomson, and if that be a correct determination Klug's species 

 has no relationship with mine, which may be regarded as a new species 

 and may still be called iynobilis.
