November 19Ü3. 



Arranging the Neuropterous Insects in the collection of 

 the Leydeu Museum I found the type-specimen of the 

 above mentioned species with the names »Raye" and »Cal- 

 koen" on the labels of origin. Asking Mr. Ritsema, he 

 told me that, according to verbal communications of his 

 predecessor, the late Dr. S. C. Snellen van VoUenhoven, 

 Messrs. Raye van Breukelervv^aard and Calkoen were col- 

 lectors in the beginning of the 19th century, from whose 

 collections Olivier has described several species. The labels 

 are in Dr. Snellen van VoUenhoven's handwriting. 



Ascalaphus macidatus Oliv. This is in the best condition 

 of the three types, though the antennae and left hindwing 

 are wanting. Its label bears the indication »Raye, Gallia 

 meridionalis". No doubt this is the same species as Asca- 

 laphus niger Borkh. 



The type-specimen of Myrmeleon hifasciatum Oliv. is in 

 a worse condition, the abdomen and antennae being lost 

 and the wings being eaten at their base by Acari so that 

 they should fall off if not supported by a piece of paper. 

 This specimen bears on its label: »Raye, Pr. b. Sp." and 

 was placed behind a label bearing the name »? hifasciatus 

 Oliv." — There were in another box two specimens of
