A. TULLGREN, HYMENOPTERA ACULEATA FROM THE CAMEROONS. 437 



of the abdomen is a little different and the sculptare of the 

 thorax especially the postscuteilum and the median segment 

 is a little more acute. In consequence of these differences I 

 separate these two specimens from the following species and 

 ref er them until further notice to S. ochropus Stål. 



S. magnificus Tullgr. n. sp. (Pl. 22, fig. 2 a, b). 



Of this new species the collection contains one female 

 and four males from Kitta («/», 23 /s, "/*» 14 A 1891). 



Female. — Very like the preceding species. Black, the 

 mandibulse red-brown at the base, the scapus clark brown, 

 darkest above, the legs except the coxse perfectly light red- 

 brown. The head, thorax and legs very densely clothed by 

 a bright velvet-like golden brownish pubescence. The epipy- 

 gium brilliant ferrugineous and the abdomen with a distinct 

 golden brownish effulgence in certain lights. 



The clypeus is very broad of perfectly the same shape 

 as by the previous species. Labrnni a little emarginated in 

 the middle. The eyes touch the base of the mandibulae. 

 The interval between the eyes on the vertex as lon g as the se- 

 cond joint of the flagellum. The interval between the poste- 

 rior ocelli half as long as the distance from the eyes. 



The pronotum very large, rounded in front. The hind 

 margin slightly curved and the distance from that to the 

 collum a little more than 3 /s of the length of the mesonotum. 

 The mesonotum with a very distinct middle carina. Postscu- 

 teilnm nearly without conical process. The median segment 

 very large rounded at the sides and with fine transverse 

 wrinkles above. 



The wings as by the previous species. 



The legs very long with the longest spur of the pöste - 

 rior tibia much shorter than the half of the me t åtar sus. The 

 claws with two basal teeth. 



Length 42.5 mm. Exp. 73 mm. 



Male. — Very similar to the female but the abdomen 

 with the two basal segments on the back mostly greenish 

 yellow only with the margins black. On the ventral side 

 two large longitudinal yellowish spöts. 



The clypeus as by the female. The labrum very indi- 

 stinct emarginated. The longest interval between the eyes 

 on the vertex a little longer than the second joint of the fla-
