reddish, and the claws have the basal half red ; hind margins of 

 abdominal segments, and the teeth on sixth segment, red ; mandibles 

 bidentate, the inner tooth rounded ; clypetis not at all keeled, the 

 punctures larger in the middle than at the sides, the anterior margin 

 a little produced and truncate in the middle ; hair of head and thorax 

 dull white, not abundant, on posterior part of pleura it is reddish ; 

 tegulse ferruginous, fuscous basally ; wings yellowish hyaline, apical 

 margin a little darkened, nervures ferruginous ; the scanty hair of 

 legs mainly black or fuscous, but the tarsi fringed with bright fox- 

 red hair ; first two abdominal segments with much bright fox-red hair ; 

 hind margin of fifth segment and upper surface of sixth, rather 

 thinly clothed with red hair ; first two ventral segments with scattered 

 reddish hair. 



Hab. — Ekuiva Valley, W. Africa, at flowers of a native species 

 of mint, collected (1907) by Dr. F. Creigbton Wellman. The 

 specific name means black and red in the language of the Sula 

 Islands. 



Another species of Creightonella, differing by the colour of the 

 hair on the tarsi and ventral abdominal segments, &c., has been 

 described by Friese (Zeits. f. Hym. Dipt. 1903, p. 273) as 

 M. sexdentata. Unfortunately this name was used by Eobertson 

 in 1895 for an American species, so it will have to be changed. 

 j\l. mandibulata. Smith, is also perhaps a Creifihtonella, but this 

 cannot be definitely determined without an examination of the 

 types. 



It may be as well to record here that Dr. Wellman also took 

 Megachile ianthoptera, Smith, in the Ekuiva Valley. 



BIBLIOGEAPHICAL AND NOMENCLATORIAL NOTES 

 ON THE EHYNCHOTA. 



By W. L. Distant. 



Mr. Kirkaldy's last disputation on names and words {ante, 

 p. 123) has quite bewildered me. He writes : " In using Lepto- 

 coris I have simply selected the name which is proper under the 

 rules followed by every living hemipterist but Mr. Distant." As 

 Dr. Bergroth is still living (and we all hope will live for many 

 years to come), that statement seems inaccurate. If he is not 

 living, as I absolutely disbelieve and have proof in a recent letter 

 to the contrary, what is the meaning of the sentence: "It is 

 because Bergroth is so strict an observer of the law that I feel 

 sure he would now use Leptocoris " ? Dallas's work may be 

 " nearly sixty years old." but if Mr. Kirkaldy bad referred to it 

 and studied the genus rather than the name which represents it, 

 he might have avoided redescribing the form Serinethataproban- 

 ensis, Dall., as Leptocoris bahraiiiy Kirk. However, we all make 

 mistakes.
