104 THE ENTOMOLOGIST. 



vein about twice its own length distant from the mid ; lateral vein- 

 scales long and straight. Halteres creamy. Length, 4-0 mm. 



Habitat. Bihe, Angola. 



Observations. — Described from a perfect female. It is a very 

 distinct species, easily told by the thoracic and abdominal orna- 

 mentation and leg-banding. It clearly comes in the genus 

 Danielsia, but the scutellar scales are rather broader than in 

 the type (D. albolineata).

PREOCCUPIED NAMES IN COLEOPTERA. 



By T. D. A. Cockerell. 



There is urgent need for someone to go over the generic 

 names used for Coleoptera, and sift out the homonyms. For 

 some reason coleopterists seem extraordinarily careless about 

 homonymy, and it is evident that some of them, while proposing 

 numerous new generic names, never take the trouble to consult 

 the indices of Scudder or Waterhouse. Alexia, Steph., 1835, is 

 the name still in use for a genus of Endomychidai, but it is 

 invalid because of the molluscan Alexia, Leach, 1818.* Fair- 

 maire still uses the name Anodon, proposed in the seventies, for 

 a Dynastine beetle, but Oken used Anodon in Mollusca in 1815. 

 The Dynastine genus may take the name Paranodon, n. n. 

 Coryphus, Cski, 1902, for an Endomychid genus, would be con- 

 sidered by many a homonym of Corypha (Gray, 1840 ; Walker, 

 1860), but I think it may be allowed to stand. \ Weise, in 1902, 

 proposed Stenella and Spilonota as the names of two Chrysomelid 

 genera, but both names are invalid (Gray, 1870; Stephens, in 

 Lepidoptera). Stenella may be changed to Stenellina, n. n., 

 type Stenellina marginata (Weise), and Spilonota may become 

 Spilonotella, n. n., type Spilonotella sag ax {Spilonota sagax, 

 Weise). The original descriptions are in Arch. Naturg. vol. 68, 

 pp. 145 and 151. In the same paper, Weise proposes a genus 

 Sphondylia, which many would consider too like Sphondyla (Illi- 

 ger, 1805). 



* Since writing the above I have found that, according to Mr. B. B. 

 Woodward (Journ. of Conch. 1903, p. 361), the date given for the molluscan 

 Alexia in the ' Nomenclator Zoologicus ' is wrong ; that is, it is the date of 

 Leach's manuscript, which was not actually published until 1847. Hence 

 the coleopterous name stands, and it is the familiar molluscan Alexia which 

 has to go. 



f It may be added that the arachnid genus-name Coryphceus, Cam- 

 bridge, 1895, is a homonym of Coryphaeus, Gistl, 1848.
