islands with the omission of New Guinea is to a great extent one of 

 convenience only. IVIany more Papuan species will undoubtedly be 

 found in the Solomons and the meagre list from all the small islands 

 will unquestionably be greatly augmented by intensive collecting. 

 However, the mere fact that Mann obtained over one third of the 

 species previously collected by Froggatt would seem to indicate 

 that the fauna may not be so very extensive. 



Stephanidae 



Stephanus froggattii Cameron. 



Megischus frogattii Cameron, Proc. Linn. soc. N. S. Wales, 1911, 36, p. 357. 



There are six specimens including four females and two males from 

 Auki, Malaita; Tulagi; Fulakora; and Malaili. The larger females 

 from Auki are 26-31 mm. in length and have the accessory femoral 

 teeth better developed than the smaller ones (21-23 mm.). The 

 males measure 20-21 mm.

0^ . Length 7-8 mm. Black, head pale yellowish from mandibles 

 to just above antennae, the inner orbits narrowly pale to the level 

 of the lower tubercle; posterior orbits, wider above, wdiite; antennae 

 piceous, with the base of the flagellum fuscous; palpi piceous; pro- 

 pleurae rufous below; front legs brownish yellow in front; knees 

 and tips of tibiae of all legs whitish, their tarsi honey-yellow. AVings 

 slightly infuscated. Head rugose, transversely so on front below 

 and on vertex medially; three lower tubercles of vertex about equallj^ 

 developed; intra-ocellar ones much weaker; cheeks smooth, malar 

 space as long as first flagellar joint, not furrowed; hind margin of head 

 carinate, but the carina not strongly developed nor recurved. Third 

 and fourth joints of flagellum of antennae the longest, subequal; 

 second twice as long as first, these two together as long as the third. 

 Pronotum in front transversely wrinkled, the wrinkles extending 

 obliquely on the pleurae; on each side with a coarsely punctate area 

 before the smooth posterior margin. Mesonotum with a median
