longest interval on the vertex between the eyes as long as 

 the joints 1 + 2 + 3 of the flagellum. The interval be- 

 tween the two posterior ocelli shorter than the distance from 

 the eyes. 



The metathorax with two very small pointed protube- 

 rances. 



The wings light fuscous, a little darker at the anterior 

 margin. No darker band at the exteriör margin. The dis- 

 tance on the radial nervnre from the end to the inserting- 

 point of the third transverse cnbital nervure longer than 

 the distance between the third and second transverse cnbital 

 nervure. 



Length 18 mm. 



Exp. 34 mm. 



S. 4-punctata Tullgr. n. sp. (Pl. 25, fig. 12 a, b.) 



This species, of which only a single female is brought 

 home, must be referred to the subgenus Parar/ris Sauss. and 

 is likely to be very nearly related to S. aestuans Fabr. 



Female. — The head is black except the cheeks and the 

 clypeus, which are reddish brown, the dark brown inandibulse 

 and a yellowish red triangulär spöt in the front. The an- 

 tennse are reddish. The thorax is except the black mesono- 

 tum entirely reddish brown. The legs dark reddish brown. 

 The first abdominal segment for the most part reddish brown. 

 The second dorsal segment in each front-corner with an in- 

 distinct reddish spöt and behind these two larger yellow 

 ones. The third dorsal segment also wdth two larger yellow 

 spöts. In other parts the abdomen is black. 



The mandibulai slightly curved, at the inner margin 

 with three emarginations. The clypeus ovate, at the apex 

 truncated, slightly longitudinally striated. The longest in- 

 terval betw T een the eyes on the vertex as long as the joints 

 2 + o + 4 of the flagellum. The interval between the poste- 

 rior ocelli a little shorter than the distance from the eyes. 

 The maxillary palpi probably 4-jointed. 



The postscutellum and the metathorax bidentate. 



The w T ings hyaline fuscous, a little darker at the ante- 

 rior margin. The third traiisverse cnbital nervure touches 

 the radial nervure in the middle betw T een the end and the
