the middle line of the mesothorax is quite strongly sulcate, and the 

 punctures are dense along this depression ; sides of thorax with rather 

 copious white hair ; tegulse black or very nearly so ; area of meta- 

 thorax well defined, minutely but very strongly cancellate ; scutellum 

 obtusely bigibbous ; heart-shaped posterior face of metathorax with 

 sharp borders ; legs black, with coarse white hair ; last tarsal joint 

 rufous ; hind spur of hind tibia serrate, the teeth evident ; wings 

 dusky hyaline, not yellowish ; stigma and nervures piceous ; third 

 t. c. and second r. n. weakened ; first r. n. joining second s. m. 

 at its extreme apex, but not quite meeting the second t. c. ; abdo- 

 men moderately shining, the punctures very minute ; triangular 

 patches of wdiite pubescence at lateral bases of segments 2 to 4, 

 very conspicuous ; no apical bands, and the apical margins black 

 like the rest. 



Hab. Chiyaka, Benguella, September 1st, 1907 ; flying with 

 Ceratina geigerice at flowers of Geigeria sp. (F. C. Wellman). 



General appearance like that of H. opacns, Perez, but opacus 

 has the mesothorax shining, with very much larger and stronger 

 punctures. H. geigerice belongs to the group of H. quadrinotatus 

 (Kirby) and H. sextiotatus (Kirby) — a group characteristic of the 

 Northern Hemisphere.

 NOTES ON THE BHYNCHOTA. 



By W. L. Distant. 



Mr. Kirkaldy {aiite, p. 14), in reference to the genus Platy- 

 lomia, Stal, writes : — " Distant says that this was not described 

 by Stal, and was only a name in 1870. On the contrary, it was 

 described by Stal (in the place cited by Distant), who doubtingly 

 ascribed ^anc^a, Gu6rin, as the type." The plain interpretation 

 of such a statement is that I overlooked the description, and 

 made an erroneous report thereon. So far from this being the 

 case, I had previously (Ann. Mag. Nat. Hist. (7), xv. p. 65 

 (1905) ) fully explained my reasons for considering Stal's short 

 description as inadmissible, though retaining bis name for the 

 genus. Reference to this opinion is under the genus in my Cata- 

 logue, which Mr. Kirkaldy has ignored. I also referred as to the 

 description of the genus to Faun. B. I. Rhynch. iii. p. 100 

 (1906), a book which Mr. Kirkaldy possessed, as he has elsewhere 

 made several references thereto, and there I repeated the course 

 I had pursued. The character given by Stal, " ramo vense 

 ulnaris interioris recto vel leviter curvato," was evidently taken 

 from Guerin's figure, a character, as I stated, " given by the 

 artist and not found in the species." Therefore, ^aric^a, Guer.,
