Hah. Hiiiteiland of Benguella, W. Africa, Jan. 3, 190S 

 (F. C. We/lman). 



It was taken, along with nu'uerous otiier bees {Anthophora 

 ccerulea, Friese, $ , Cr< cisa picta, Smith, ? , Apis adansoni, 

 Latr., worker, &c.) at a small patch of flowering Coiupositte, 

 species of Othonna and Geigeiia. 



Thrinchostoma orchidarum, sp.. n. 



(^ . — Length a little over 11 nun. with tiie liead thrust 

 forward ; anterior wing Sf mm. 



Black, with the hair on head and thorax above mainly 

 ferrui;inous, but on cheeks and pleura white; sides and 

 middle of face with dense white hair; clypeus greatly pro- 

 duced as usual^ its apical margin broadly light yellow ; tongue 

 long and slender, orange, very hairy ; palpi clear ferruginous; 

 last joint of maxillary palpi long and slender; antennaa 

 ordinary, flagellum ferruginous beneath; eyes prominent; 

 mesothorax and scutellum extren)ely closely and densely 

 punctured; tegulse clear ferruginous. Wings ample, ferru- 

 ginous-tinted, stigma and nervures ferruginous; costal margin 

 with short dark h lir ; apex of wings not infuscated ; second 

 s.m. large; second t.-c. with a patch of black liairas usual in 

 the genus, but straight (not l>ent as in T. bicometes) ; third 

 t.-c. almost straigiit (not curved as in T. wellinani) ; third 

 s.m. receiving both recurrent nervures at about equal distances 

 from a}>ex and Ixise ; femora black; tibiae with a yellow 

 basal spot and more or less yellow apically ; hind tibiai broad, 

 triangular, with a greatly produced and eidarged inner angle, 

 on the lower side of which the two sjjurs are seen, widely 

 separated ; tarsi clear light yellow, the apical two or three 

 joints ferruginous; abdomen black, with the hind margins of 

 the segments broadly brilliant silvery, the apical segment 

 with black hair. 



From the structure and colour of the wings this cannot be 

 the male of T. loellinani. It is also quite distinct from 

 T. bicometes {IJi<i(jonozus bicometes, Enderlein) and 'T. pro- 

 ductutii (Smith). lis closest affinity is with T. renitanteli/, 

 Saussure, from Madagascar, but it differs in several points of 

 coloi'ation.
