There is considerable variation in different species of this 

 genus in the neuration, especially iii the shape of the second 

 cubital cell, which is sometimes pointed on the radial nervure 

 as in typical Milluta, but longer than the third in /. tartara, 

 Sauss. There seem, however, to be so many intermediate 

 foi ms that I cannot regard the character of generic importance. 

 The radial cell also varies in length and is more or less 

 truncated at the extremity ; Ashmead says that it is lanceo- 

 late in nocfurna, Mor., but in the original description 

 Morawitz distinctly says *' die Spitze mehr oder weniger 

 deutlich abgestutzt." The antennae also vary much in length, 

 but this might be expected in insects which have become 

 adapted to nocturnal habits. I have not seen specimens of 

 Milluta chchauti, Andr^, or of Magrettina nocturna, Mor., 

 the species given as typical of those genera ; but a specimen 

 in the British Mu.seum from Ormarah, Baluchistan, corresponds 

 well with Andie's description in most respects, the inter- 

 mediate coxae are, however, narrowly separated. Kadoskowsky 

 gives good plates of the male genitalia, which differ much 

 from typical Myzine, but do not seem to show any affinity to 

 Methoca. The only female I have seen, Komaroicia vicioriosa, 

 Radosz. = /. tartara^ Sauss., seems to me to show conclusively 

 that the genus is nearest to Myzine. Much more material is 

 required for a thorough study of the genus, but until this is 

 available it is better to abstidn from any attempt at generic 

 subdivision. Mons. Andre has probably overlooked Iswara 

 owintT to Westwood's mistake in placing it in the Thynnidae. 

 I agreO with him in treating the distinctions given by 

 Ashmead for Magrettina as specific and not generic ; but I 

 cannot consider the genus correctly placed in the Mutillidse.
