228 ENTOMOLOGICAL NEWS. [May, '08 



Angola are of great interest, my small collection having al- 

 ready turned up several fine new forms, including a new genus. 

 The peculiar abdominal pouches of the Xylocopid group, en- 

 closing parasitic mites (Paragreenia Ckll.) is also most in- 

 teresting, as is the mimicry and parasitism in the whole familly.

No. 1554. Tabanns biguttatus Wied. (Dipt.) 

 This fly is representative of the powerful group which in- 

 cludes, in my collection, several new species. T. latipes Macq. 

 is the handsomest member, while the one named in the title to 

 this note is of special interest on account of its mimicry of a 

 wasp. The two species here named, with several others (not- 

 ably T. socius Walk, and T. rubricundus Walk.), make life a 

 burden to cattle, and occasionally attack man. 



25- 

 No. 1060. Clytus semiruber Qued. (Coleopt.) 



A common Cerambycid beetle (represented here by a variety, 

 probably new) which is typical of a large group. They do 

 great damage to dry timber. C. semiruber (which is distaste- 

 ful and rejected by insect-eating animals) is a Mullerian mimic 



of Zonabris dicincta Bert.

No. 1555 seq. Salius spp. (Hymenopt.) 



Such formidable wasps as Salius vindex Sm., 5". dedjax 

 Guer., and 5. regina Sauss., are reinforced by scarcely less 

 powerful representatives of Scolia, Synagris and Sphex. The 

 number of species is very large in the region, and the more 

 aggressive ones are best left alone. I once saw a gigantic 

 Salius chase a native boy several rods. The sting of such 

 wasps is severe. The group as a whole is a fine one and several 

 of my specimens are new to science.

 No. 1246. Hacinatopota ocellata Wied. (Dipt.) 



I have taken a considerable number of Hacmatopotac nearly 

 a dozen of which have been pronounced new species. These 

 flies are a terrible pest in the wet season, both to men and
