This geuus is founded ou Cryptus formosua Brulu', It 

 certain!}' cannot be retaiued in On/ptus as that geuus is uow 

 defined. In Ashmead\ arrangement (N. S. Nation. Mus. 

 ]<XIII, 39.) it would come in near Cryptoideus and Crtjpto- 

 pteryx; but it cannot well be confouuded with them. The traus- 

 versely striated metathorax, toothed clypeus, shallow striated 

 parapsidal furrows and fuscous-violaceous wings are characte- 

 ristic features with the geuus.

 on Anaphe reticnlata, a species of Bombyx, which spins its 

 cocoous in large masses. Cf. P. Eut. Soc. Loudou, 1878, 23 

 and 42. Tt appears to hâve a wide distribution iu Tropical 

 and South Africa. It has been taken by the Rev'l- ./. A,
