NEMATUS ANTENNATUS. 155 



The pupa state is passed in the earth, the cocoon 

 being close, thick, elliptical, and, like those of the other 

 species, is covered on the outside with grains of earth. 



The imagos appear in June. They are very com- 

 monly distributed. Kintail, Clydesdale, Berwickshire, 

 Eannoch, Braemar, Sutherlandshire, near Newcastle 

 (Bold), Manchester, Lastingham, Worcester, Glou- 

 cester, Grlanville's Wootton, London district. 



Its European distribution is very wide. Greenland 

 (Schiodte, Berl. Ent. Zeit., iii, 144), Lapland, Fin- 

 land, Scandinavia, Holstein, Germany, Bohemia, Hol- 

 land, France, Italy, Switzerland, Austria, Curland, 

 Casan. 



Obs. The Tenthredo ventralis, Panz., which Hartig regarded as this 

 species, is a Selandria (cf. Giraud, Verh. z. b. Ges. Wien, vi, 187). 

 Tischbein (Stett. Ent., xxxii, 253) describes and figures a monstrous 

 forewing, the neuration being very irregular.

 PL XXIY, fig. 4, Saw. 



Nematus antennatus, Cam., Ent. M. M., xiv, 58 (1877) ; Andre, 



Species, i, 221 ; Cat., 24,* 190. 



Reddish-luteous ; the greater part of the head, the antennae, the 

 sternum, three large marks (almost confluent) on the mesonotum, the 

 scutellum, and the metanotum black. Wings hyaline ; stigma red- 

 dish-testaceous, black at the base. 



Length 3 lines. 



This distinct species agrees with N. bilineatus in 

 having black marks on the mesonotum, but these are 

 very much larger, occupying nearly the whole surface ; 

 the mark on the breast is larger, the pleurae beneath the 

 wings are marked with black, the thorax generally is not 

 so deeply punctured, the incision in the clypeus is not 

 so deep, the mouth is dirty, not clear white, the stigma 

 is broadly black at the base, and the third cubital 

 cellule is very much shorter, more so, indeed, than in 

 any other species in the group, while the second 

 recurrent nervure is farther removed from the third
