T. brevipennis ajipears to imlicate tliat he did not count tlia 

 basal joint. I j)lace these insects in Ashmead's genus 

 Tetralun'ieUa (type T. ciraja, Eversm.), although they do not 

 wholly agree in the vi-nation. If \vc allow a moderate 

 latitude iu our definition of Tefraloniella, it cannot very 

 well be separated from the American genus Xenoglossodes. 

 The genus Xenuylossodes was doscribeil by Ashmead (1899) 

 iu the same ])aper as Tetraluniclla, but on a later page^ so 

 Tetralon'u'lhi niu.st be given priority. Before sinking Xeno- 

 yhssodes, liowever, it will be necessary to carefully compare 

 T. graju, a species I do not possess. 



1 liave regarded Melissodes and its immediate allies in 

 America as of southern or neotropical derivation. It is now 

 evident that Xenoglossodes represents a northern or holaretic 

 type, from which Melissodes and Xeyioglossa have been 

 derived iu America. 



Ceratina (Ceratinidia) eburneopicta, sp. u. 



? . — Length 6^-7 mm. 



Like C. morawitz'ii, Sickm.^ but all the markings ivorv 

 colour instead of bright yellow ; wings clear hyaline. Dis- 

 tinguished at once from C. hieroghjphica, Sm., by the small 

 size and the very densely punctured sides of mesothorax in 

 front. 



Hub. N.W. India [Comber), British Museum. Type 

 from Salsette ; another from Khandala. 



Perhaps only a local race of C morawitzii. 



Ceratina sexmaculata, var. purpurascens, var. nov. 



S • — Deep blue-green, the head, tliorax, and abdomen 

 strongly clouded or suflused with purple, especially the 

 front, vertex, and. mesothorax. Seen without a lens, the 

 insect appears deep purple-blue, and looks just like Chrysis 

 cessata, Buyss., except that the colour is hardly so bright as 

 in the Chrysis.

Ceratina bingharni, Ckll.

Ceratina comberi, sp. n.

 Like C. bingharni, but smaller, golden green, strongly
